Service has definitely been degraded since the switch from Insight. I was getting pretty consistent averages close to the 10/1. Now average halved and latency doubled and pretty jerky. I reckon I can say that I have been 'Comcraptic' initiated. I am not all to happy or satisfied with my service right now.
Update 3/7/2008
AS in my previous assessment. My user experience basically halved. I was using a Dlink DCM-202 Modem. Apparently Comcast did not have me modem registered. That was odd seeing as I registered it with Insight a little over a year ago. Comcast had my original RCA-425 modem registered I had gotten from Insight when I first started service. After spending about 21/2 hours registering my Dlink, the issues were not fixed. In fact I could not upload?!!. Dlink had a firmware upgrade specifically for Comcast users on the 202 model. So I figured ok...i'll try it. Well after the firmware upgrade the issues still wasn't straightened out. Then I found out that the firmware upgrade disables the tftp so you downgrade or revert back to the original. Something Dlink neglects to tell you on the site or in the 'instructions' SO DON"T DO IT is my suggestion for us former Insight people. Your Older RCA-425 is probably a bottle neck for your connection. It was on mine. I bought a new SB-5120 from Newegg with a promo code for free shipping. I figured I had not much to loose seeing how I considered my DCM-202 bricked and me RCA-425 slow. I have to tell you folks IT MADE A BIG DIFFERENCE!! Comcast is still having intermittent issues especially around peak time. Tier 2 tech assured me they are aware and are working diligently on them. Well I am not holding my breath,
3/14/2008
Lots of Phone call disconnects when calling support...even when just trying to call the Number sometimes I get disconnected right away. This time I actually got a 'ticket' number & I declined a service tech call because I know that it would be fruitless at this time. I did manage to pull a partial credit for the issues I had been experiencing. I found out that some of the effects included ssl errors & a full minute to sync Imap folders or Outlook times out in an email account. I wondered why I was having issues with updating/syncing My Quicken & Bank info for a week...
3/16/2008 PM
There has been a few times I have managed to experience moments of seemingly unfettered smooth sailing on the net and have actually managed some respectable speed tests. However I don't believe the 'Speed tests' really give an accurate reading of the 'real world' internet experience. So i go to sites where i have downloaded things in the past ie: Microsoft.com and download maybe a SP2 or something. On Insight average would 1200-1300- KB/sec. Since Comcast takeover it now averages 500-600 KB/sec.
I never have mentioned about the Cable tv service before so I will now.I just have basic 'cause I don't watch TV that much. However, the few channels I do watch occasionally have sometimes experienced distorted sound and occasional picture distortion (The little fleeting squares)
3/16/2008 PM
Now the service really sucks
3/25/2008
Some times when you think they have it all straightened out.Then more issues happen.
4/07/2008 AM
Still experiencing a lot of intermittent issues. Naturally Comcast wants to waste my time and theirs to send out a truck. I exclaim what for?? Besides the last person that came out confirmed there isn't anything wrong with me modem and inside lines or the drop and the immediate neighborhood. ..the intermittent issues are on comcast nodes above me like in Chicago and Boston.& why in the hell am i being routed to boston from the midwest to visit a sever thats located on the west coat? Gee that makes perfect network manageability sense to me.
4/13/2008
Yada Yada...same ole craptastic intermittent issues and &%^$% support. BTW the email Rick Germano thing is just a PR placebo.
4/26/2008
Internet has been a bit more stabilized per norm. But you never know exactly when you would mysteriously get cutoff in the middle of something. Such as what happened last week for 5 1/2 hours. However there are still occasional persistent intermittent issue on some nodes. The Basic cable service I have is even taking a licking from comcast compression and routing tactics. Insight service was sooo much more dependable and reliable in the end...
4/30/2008
Have another tech scheduled to come out...just to waste my time and confirm that is is nothing on my end...BTW I getting so annoyed at that stupid voice menu/speech/ marketing crap...just get to the chase I say
5/2/2008
I had to cancel the scheduled tech visit because a more demanding issue came about that required my presence elsewhere. I did get an email response from a "Comcast Rep". I have yet to email all my data to them.
5/4/2008
Until these issues are resolved, I am going to do my best to keep this review on the front page to divert what I sense are some of Comcasts paid poster/reviewers. I have notice a few folks posted a thread in the forums about a node/router in Connecticut (& other places) dropping packets big time. It just so happens to be one of those nodes/routers that is affecting me in Northern Illinois that I have repeatedly reported on numerous occasions. One in Massachusetts is another that acts up frequently and affects me here.
One thing I have to say... If Insight can whip together a full fairly reliable network in about a year with less resources & experiences than Comcast, why on earth cannot Comcast keep/or do the same. Technically they were somewhat partners. So what happened in the transition? Other than Big Corp Greed, manipulation and moving stuff around for their own major benefit all in the meantime using the deceptive marketing media hype to promote the half truths..

Even My basic cable tv service has intermittent issues showing on various channels today.
5/14/2008
Speed test (especially flash) DO NOT give an accurate rendering of real world internet experiences. Just as certain protocols, web sites, & servers can be blacklisted (throttled or blocked) - the opposite is also true. Have you ever noticed a vast difference in the latency when running a speed test from a certain server from Flash to Java & to running just a simple ping?
A Comcast sales rep handed out a bunch of flyer's in me neighborhood offering a pretty good introductory deal. Little do they now that I am co-captain of the neighborhood watch. I communicate regularly with a lot of households. Needless to say I share the truth about my own experiences and what to really expect with Comcast.
BTW as I am pinging speakeasy.net I am showing the 5-10 ms packet losses every 20-30 ms on the ole boston node/router this morning.
5/19/2008
As per typical Comcraptic ways. The above mention Nodes are still intermittent. I must STRESS that even the cable TV is rapidly deteriorating. Most of me channels have these quaint little lines going up the screen. Reminds me somewhat of rabbit ears. Support simply sucks at best. Tech or corporate don't get off their duff to truly fix stuff. Save the New Building the fatheads can sit in & that silly social site of whatever the (*&% it is they bought.
5/23/2008
I'll give credit where credit is do. Had a tech visit this morning about the quaint lines in my Cable TV service this morning. Apparently & highly probable it appears to have been a bad splitter that I really didn't need in the first place. (It was something leftover from before Comcast & NOT inline with the cable modem/internet) I won't fault Comcast on that one. I'll give the tech that came out a thumbs up for prompt and thorough inspection and troubleshooting.
I do have a hard photo of my TV with some green lines taken on 4\20
2008 However I believe that was a totally separate issue Than this recent one.
I did show the tech the data I have been collecting about my internet experiences. He suggested I take it to the supervisor locally. That can be arranged seeing as how they are not far from me.
6/7/2008
Woke up this morning and booted comp up to a very intermittent slow loading at times (Something was interfering with Various pages being called up intermittently) Home page (Google) and various other pages would take way too long to load or sometimes would load normally Speed tests and latency checks were all over the place. As usual the node IP 68.86.90.58 te-3-1-ar01.chartford.ct.hartford.comcast.net that appears to be in the way of most of my browsing paths is showing its typical intermittent issues. However it wasn't quite as bad as I have seen it in the past. So this is a bit puzzling for me. I'll chalk this up to one of their 'Deep Packet' inspection hardware boxes interfering with the syn_sent or the receive packets from my browsers. On the other hand, just to be fair it appears several other level3.net (nodes/routers) were having occasional packet losses too.
Comcast support was running on the usual script per norm and of course they offered to roll a truck. I asked, "What for? You still hadn't really fixed the other (Internet) Comcast network issues yet thats above me since the last few tech visits."
6/11/2008
Internet service is the crap again. So what else is new aye. Can't even call support today from cell...reckon thats my fault too that even the call center is &^(^$%*$ up.
6/14/2008
Don't consistently get alleged advertise speeds even OFF "peak' Hours. Customer service and networks techs simply suck at best. Service is not 'smooth'... is spotty, jerky (cuts in and out) I really Hate the robot thing when one calls in with a bloody passion. What an absolute annoyance. Even that part of their service is not consistent or reliable. (Go figure aye). I am tired of doing the same ole 'script' only to still be where I am at today. Comcasts service and support simply doesn't hold a candle to my former ISP Insight despite all the marketing hype and empty PR double talk.. Yet they raised rates pretty much across the board claiming an 'Increased value of service. What a bunch of true BS. All the various 'Deep packet inspection' hardware, protocol agnostic, monitoring and other crap they use, actually hinders and adds to the instability and performance issues. Makes trouble shooting and diagnostics a much more pain in the backside & it leaves the generic tech support people clueless and inept.

With A 10 down and a 1 up service (Before the Media Marketed propaganda 'Powerboost') One would think that to send an email with approx. 8 MB attachment (Something I very rarely do), it wouldn't take all but a couple minutes MAX to send. How about a full 7 minutes!! Very Nice...yah right.
Time to spend calling support= 2sec.
Listening to robot to get to live person= 1-5 min
reciting 'scripts' before CSR= 10 min
User experiences from Insight to Comcast average ratio= (negative) -33-50%
Actual 'Real' or 'long term' solutions applied= ???
Real User Experiences= Priceless
Must be why they figure it as an 'Increased value of service' uh?
6/30/2008
I can no longer connect to local office...so i have to go through the other number and if I am lucky get cut-off during transfer so i can listen to that crap all over again. Aaarrgg!
Finally got a live one. #CR129479 the tech on the phone even noted intermittent High pings from his end to my modem. As per protocol. I get to blow part of a day for a truck roll. I also take the opportunity to remind them once again of the troubled nodes/routers I have been noting.
note...generally the speeds have been about half of what they should be these last couple of weeks.

ge-1-2-ar03.area4.il.chicago.comcast.net showing 29% loss Immediately after that I ran PingPlotter (TCP packets) against Pingplotter.com and te-1-4-ar01.woburn.ma.boston.comcast.net shows average of 50% packet loss. Comcast has us screwed coming and going. Go figure. View image
7/05/2008
Tech was here on time (Former Insight employee...Sincere thanks for Comcast keeping the "Local workforce') Tech was professional and thorough. He checked everything, looked at my data collected. Even ran his lappy bypassing router confirming my results. Again...Its not on my end that these issues are happening. I am gonna call it node overload or deep packet inspection/compression hardware issues. Whatever the case is, I am NOT getting what is marketed or I am paying for.
Naturally it was 9 am day after the 4th so network wasn't nearly as bad. However it was still below par.

Results of the tech visit are yet to be seen. I trust this guy will follow through on his reporting this for a real workable solution

Still Waiting for a longer term solution to be applied...aka 'fixed network' screw the powerboost, stop compressing the snot out of everything and just stick with reasonable reliability aye!!.
Comcast nodes/routers ARE overloaded.

Another grand evening of spotty, jerky, packet dropping and sub-par internet performance for what one ‘allegedly’ pays for. I am in the process of ‘testing’ a certain config file for what is known as Blast (16/2). I must confess, I am not too impressed. I do not see/experience much difference that what I ‘allegedly’ had (10/1) save the upload is a little bit better. Of course we all know that that what I had (10/1) was performing subpar in Comcast’s hands opposed to when it was in my original ISP’s (InsightBB). Generally, we are cruising about half speed and jerky. I ran some more PingPlotter Plots using three different types of packets, pinging three strategic domains (I will not post them here). One was Comcast’s very own. Naturally, the router/nodes or whatever one chooses to call them today I have been consistently griping about are still intermittently dropping packets
.
Some excuses ISP’s like to use is “It’s not on our network”… “We are not responsible for other networks”… or something along the lines of: We are not responsible for the delivery/speed outside our networks and even then, it is worded ’UP TO’… & THAT depends on certain conditions (of course one of them is termed “network”. These statements and ideologies may be true in one perspective. However, they are also used as a ‘reasonable’ cop-out for what appears to me as blatant irresponsibility.
Whose network we complaining about here?? When I do browse other places outside your (Comcast) network, do I not pass through devices on your (Comcast) network to get to them (Other networks) and vice versa??
Let us have a show of hands of people that that do all their browsing, posting, forum hopping, music listening/downloading, video watching/downloading, banking, online shopping, software patches, online courses, web work, research & all the other things folks do on the net… On & limited too their ISP’S own specific network…hmmm
Yet the Marketing Media Propaganda portrays it as…’DO EVERYTHING’ faster and better with our service (Which btw implies network) Tell me please how that will that happen when their own network cannot keep up and/or perform with the service they offer and sell?
If I recall, this review falls under the ISP of Comcast and I do specifically remember me posting images (see below or go here »/comment/67268 ) and such about certain troubled routers/gateways with the ending of COMCAST.NET that are consistently intermittently dropping packets, Thus, drastically affecting my internet experience.
See recent from another angle »/linequality/nil/2410639
From my own experiences of the ‘Blast’ (16/2) these last 2 weeks is nothing but a ‘sound good’, ego boosting (Cuzz I got blast) theoretical cool thing that one technically pays more money for and gets less product (Personal experience with data to back it up) I call it deception or to put it lightly “LIE”. Comcast couldn’t even keep up with the 10/1. Former InsighBB customers were promised that we would have the same uninterrupted service, performance and speed that we experienced with InsightBB for at least a year. Well the Year is half over; so far we are getting the shaft by Corporate BS.

Oh, Gee Comcast…. Your bank is NOT ON MY BANK NETWORK. So I am not responsible nor can I guarantee the delivery for the ‘UP TO’ my full bill payment
8/172008
I have resisted posting anything on here for several weeks for 2 reasons: 1) been real busy in real life 2) trying to give Comcast a fair shake at 'catching up'
Apparently, Comcast HAS been doing some things to improve user experiences in my particular area. from what I can tell. I have not seen the consistent packet losses noted in previous posts.
I have been noting a considerable degradation in 'Speed' performance during 'Peak' time. (Generally 2/3rds of the normal using the internet time) Even with the highly media marketing propagated 'Powerboost'.
Apparently the 'Powerboost' works well OFF peak hours. But what about 'Peak' hours? Does it turn off then? Doubt it very seriously. Then why the serious degradation in performance during 'Peak' hours. I think the powerboost just manages to keep you at about 'provisioned speed' during the speedtests at those times never mind the 'sustained provisioned speed. My observation anyway. So what does that really tell an inquisitive mind aye?
Below is a copy of an email I sent to the Comcast reps that have been communicating with me.
Begin email...
Ok, I’ll put this more direct. So you bumped me up to blast and it ‘Really’ isn’t any better than the service than before. (Check out a few other folks complaining of issues with ‘Blast’.) Except, I am paying 25% more. Please tell me (stupid of me to think it was possible) How in the hell can Comcast manage 16/2 when they couldn’t manage the 10/1? When folks on the 8/2 can post similar speed tests (see 8-2 example.pdf). Evening time really sucks and you guys know it. Your overloaded and your charging a premium for services not & incapable of rending on a reasonable level. I am sure there are a whole slew of other folks that do not know better and are not aware of how or where to complain about their Comcast service too.
To top it off, Comcast evidently shows favoritism. *see this review »Review of Comcast by baineschile.
So where is the real difference? Apparently Comcast will not deliver what they claim and market. I have multiple speed tests, PingPlots and download screenshots from places all over and locally showing that.
Why is this error in my modems log files? *see logsdata.pdf (reset my modem yesterday)
REG: Capability type incorrectly negotiated by CMTS
Now we know that my system and setup can and does handle things nicely when Comcast is playing right.
In one of your emails you sent me Frank, You stated “This could be something specific to the ping plotter program or the specific packets used…”. Could be! If that were truly the case, then why is it those two specific hops on a regular consistent basis and not any others?
As I stated in my review… ‘Pay more for less’ I am not all happy or content with the dishonoring of Comcast’s word to us former InsightBB customers. Nor am I happy with false and misleading advertising claims. Nor am I happy with the performance and degradation of my prior service and the service I have now at a 25% cost increase. I am a Remodeler by trade and if I don’t perform what I say I would. Then I don’t get paid. Now you want to ()*&^)%^ my credit up because I contest my bill?
All I want is what I have paid for on a consistent level. I’m tired of the price gouging, lies, Corporate greed and deception.
end email...
My observation about the Degradation in overall performance during Peak times has been confirmed more than once using Comcast's own speedtests as well as others.

8/29/2008
I am still not convinced that the 'theoretical 16/2 blast' @ a 25% increase in cost, is any better than what i originally had and were promised that the service would not change in the transition from Insightbb. ( I still have the original letter) Now because Comcast was caught with their hand up their backside. We normal users have to pay another deceptive price. The user cap. I am not advocating those folks that use the internet to the extreme. To impose the abusers penalty on everyone else is just not right. I can read the writing on the wall. Its a dumbing down for internet access and another way to double charge for advertisements and to keep with the greed of 'Pay more for less' It doesn't matter if one has ad-blocking software on their PC. The bandwidth is still counted toward ones own use.
Remember Comcast in essence could not manage my original plan 10/1 and it appears that the 16/2 on most occasions is the same performance. the throughput after the powerblast kick is no different the majority of the time.
I am still waiting for proper compensation for Comcast own mismanagement of their network which in turn affected me.
As for the other 'Paid' reviewers trying desperately to 'up' comcast ratings score... Truth always prevails in the end. Such as that when Comcast was caught red handed about the p2p protocol forgery and they (Comcast) explicitly denied it.

Both @ 7am Sunday morning.
However come a little later in the day and at evening times one can generally halve those numbers and the is with the co vented powerboost. Take the Powerboost away and one gets the real time average speed. which equals about half on a good day. So in essence we are paying twice as much for half of *package sold. As for the 'up to' lingo. They can shove it up too the their highest backside. I am a little pissed off at the constant serious evening and weekend degradation of services.
I was doing a tile job @ a clients house when Comcast came to do an install. I was appalled at the non former comcast employee installing Comcrast's malware aka toolbar and whatever else that crap comes with. What self centered jerks!! They prey on the internet and computer illiterates for their own selfish, controlling and manipulative ways.

Supposedly they are escalating this *again to the local office. This time I made sure I got a reference number # 53358 & CSR id.

Customer support is a proverbial loop of NOT actually getting anything done. But rather a placebo to to appear as they are actually doing something and to waste ones time and resources.The bureaucratic red tape in the companies policies ensure that nothing actually gets done to the customers satisfaction or a REAL long term solution for the customers benefit. (as been noted by my reviews as well as a few other local Rockford area members that managed to find this site and post there own experiences.)
Customer service, Real technical support/solutions and the PR placebo scheme give a whole new meaning the the term 'simply suxs' So I have taken the liberty of contacting several elected state officials,CUB. FTC, FCC, Illinois Commerce Commission and the states attorney with my documented complaints, letters. tests, findings and will continue to hound them. Not all tests and finding were done from my own personal location. To ensure the broad scope of things I have run tests from several other peoples houses throughout Rockford & area. Only my own are posted.

finally been contacted on that 'double' escalated ticket. I have actually had a few Comcast folks calling me. Naturally per protocol, they are sending out yet another truck today. I asked them....gee...did it really get fixed the other 5 times?
Evidently the guy monitoring my 'line' noticed packet losses too. That's why they are rolling another truck. We will see...
In the mean time, Internet service has been sporadic today some good times and some bad. * Normally this time of the day, it's all bad...but, it's not evening yet. here is a sampling

That's with the 16/2 package and powerboost mind ya.
10/19/2008
Comcast's own internal speedtest site on a Sunday morning no doubt & it being Flash based at that with the all powerfull powerboost & Blast
Last Result:
Download Speed: 9881 kbps (1235.1 KB/sec transfer rate)
Upload Speed: 2814 kbps (351.8 KB/sec transfer rate)
This test was done after a restart * first one stalled out. Like I posted in another place appears comcasts own crap throttles its own.I reckon it truly is agnostic. But you know I pay for the 16/2. But hey at least they cant use the excuse 'It's not on our network'
11/03/2008
Just cleaned up the ole PingPlotter images from here...(Kudos to the webmaster that enabled this)
Apparently with all the DPI crap & new protocol agnostic hardware in the way. It makes it much harder to pinpoint the bottlenecks... Then again, maybe THOSE are the bottlenecks. I tend to think so. Been running a few tests from alternate sources when time permits.
Although I do not really put mush stock into 'Speedtest' especially flash. I must again publicaly note that one of the suggested sites I use was one of Comcast's own internal site. We will just say that 4 out 5 last times I used it it would countdown and almost crawl to a stop...funny aye.
Got hit with the random cable modem rental fee...even though I own my cable modem & always have. Funny it wasn't on the last bill. I have a theory that the billing program is set to randomly inject that fee for some mass, fast, oops (Hope you don't catch that) revenue generator.
As for the actual service...Not much has really changed still averaging 1/3 - 1/2 the allotted tier I have been faithfully paying for.

Bottomline Comcast service simply is unreliable and simply sucks
1/9/2009
Still averaging half of what I am paying for. Fired off a EECB with "Written notice prior to Small Claims'. Supposed to be Contacted Regional Manager.
7/23/2009
I know it's been awhile since I posted my review. I hadn't taken Comcast to small claims yet. I still have time.
Service still sucks!! still getting half speeds on average of what we pay for. I degrade my service back to the original 'Insight' tier 10/1 *naturally at a higher price than what I had* and guess what!! I am still getting (If I am lucky) between 5-9 on average with powerboost. Gee I was getting that on the 16/2. So basically they sold and billed me for a service they were incapable of actually delivering.
See 12/7/2208 post
I hold Mr. Comcastcares accountable for that. As far as I am concerned in My book, he aint nothin but an egotistical fluff bucket. Don't care much for the district manager in Rockford either. I have a letter written to me by him straight up lying. My response rebuked his tale using Comcast's own internal speedtest server. But naturally I suppose that's part of the Corporate policy is to lie. Just look at their track record. I thought about and maybe still will post that letter along with my reply here.
As of 2 months ago, the slowest link; now reports 45 Mbps T3/DS3 subnet. Comcast replaced a head of course secretly while denying there was any problem with their network. Incidentally it took care of the tin man underwater sound on the local HD channels they are required by law to transmit. But that was a whole other complaint part that took about 4-5 months to resolve. One would think it would actually help our true speeds...NOT!! maybe it's the sandvine crap that was mentioned on the front page
»Comcast/Sandvine Traffic Managment System Evolves today.
I know delivering mp3's and videos to a website I manage has a grand throughput speed of about 48-168kbs....'corrected' NOT GOOD
So what is the real deal. Folks in a neighborhood that has some true competition may see some of Comcast's better side. But as it stands we in Rockford are getting screwed!
7/24/2009
I uploaded the letter I got from the District Director here in Rockford Illinois along with my response. Needless to say Executive customer care rep Verneen Breaux mirrored the same to to the inquiries from complaints I submitted to the FCC and our States Attorney. When I confronted Verneen on how is it Comcast can say I was complaining on speed results from a server in Germany...she replied they thought a tech that visited mention something about it. Again I rebuked that notion and claimed I NEVER SAID OR ELUDED TO ANYTHING OF A KIND. Asked if they had it in writing...'No', she said. I asked how is it they can claim something as fact (evidenced by the copies of letters they sent to the FCC and Lisa Madigan) when all they have is 'what they thought was said' and heresy? Putting it in writing may constitute perjury.
Yet...true to Comcast denial and neglecting the truth Comcast negated actual hard core proof in writing nor would they own up to it. I do have several of our conversations recorded.
Unfortunately the images of the letters do not appear in proper order despite my uploading them in order. No worries though, it's there for the world to see.

7/26/2009 7:55am
Just to be fair and reduce to naught some typical Comcast excuses... I did a FTP test to my site in Dallas Texas on Site5 using the Theplanet.com Internet Services Inc group.
Mind you, this is considered early morning when LESS traffic congestion is happening. My node isn't being used as much and Comcast's protocol agnostic network management aka sandvine theoretically may not be kicking in.
I have screen shots, but will not post them here because they will interfere with the 'naming convention' of the other pics I have.
I used a 253MB wmv file
Upload averaged 134.27 KB/s....'corrected' good
Download averaged 1192.81 KB/s....'Surprise!' well within 'reasonable' performance for the 'tier' I am on now.
Maybe these recent posts are an official complaint against Comcast;s deployment of their newer 'Protocol agnostic' network management scheme.
I do know this for a fact...as evidenced by ALL my previous postings. Come 'prime time' we get the snot throttled out of us!!
07/27/2009
Not even 'Prime Time' yet..But true to Comcasts continual commitment to customer and quality of service coupled with value added 'Enhancements' we are experiencing the following this morning!!
Back to 'the slowest link 10 MB Ethernet link' Which probably explains the deterioration (random Pixelation) in on Cable video last night. I am quite sure the tin man underwater sound will be prevalent again too.

this is with PowerBoost! of course when one calls...we get the same ole scripted crap we heard for the last year and half...several techs...and supervisors...yada, yada, yada...what do we have?... aint nothing changed but rather grew worse..Yet the Ads are blasting ...spewing hyped propaganda.....It makes me want to puke.
7/29/2009
So much for going back to the original Insight 10/1 I just learned today the screwed me out of that and have me rated at their so-called even more throttled silver package (the "performance 6/384'...excuse me??? Another example of Comcratic experience!!
7/30/2009
I do have another tech visit this early evening. Will it be another fruitless trip? I am not holding my breath.
Excerpt from another post I did this morning in answer to an ambitious and dedicated Comcast rep...YES!! I actually DID say something positive. I don't hold the people who are the 'nuts-n-bolts' to Comcast's service accountable as a whole. I DO however hold Corporate policies and business model and those in charge of same accountable.
A direct answer to your question...the mean average for my previous post was 8.16Mb/s.
Knowing that those tests were using a 10 second burst up & down falls well within 'Active PowerBoost's' parameters. Please
also note the time I posted 3:38 pm central. We were starting to get into primetime.
Actual throughput was about 4.68Mb/s
I will note this was done on my Vista 32 bit...Tweaked. Using router it is the same machine I did my FTP test to my site
stated in my review on Sunday morning 7:55 am 7/26/2009 which at that time produced very acceptable results.
This morning starting @ 5:50 am I did the same FTP test to my site. Freedombuild.net using ThePlanet group located in
Dallas Texas. My site has a dedicated IP. There is only one other website I am managing there.
This test I used my Vista 64 bit machine, Tweaked, same router of course and same 'brand' Security Suite * noting for documentary purposes, Security Suites generally do increase the overhead and MOST tests I have done, have this as well as other factors in mind (there has been some documented tests I have done with with said Security Suite disabled even when I was running XP 64 & 32 * just another side note to let Comcast know, that ALL my tests I have done and documented over the last year and half were not done hastily, biased an ignorantly without considering 'other' variable factors including 'typical' networked factors...aka the other networks.
Here are my results @ 5:50 am-6:30am 7/30/2009
Using 253MB wmv file ftp to freedombuild.net
Upload averaged....133 KB/s or 1.09Mbps
Dnload averaged...1100 KB/s or 9.011Mbps
Perfectly acceptable performance for my rated tier at this time

Note that this test produced similar results as the one I did 7/26/2009 Sunday morning on me Vista 32 bit machine.
Come primetime, when there is more traffic on Comcasts network, results are greatly diminished. Which tells me
1) Comcast's network is underbuilt and oversold.
2)The Network management scheme Comcast deploys throttles the snot out of everybody benefiting Comcast but screwing the average user.
3) Demonstrates the 'PowerBoost' is really just a marketing ploy and just manages to keep more naive users deceived as to what's really going on.
4)Active Comcast ad campaigns wording can be considered false advertising in certain markets (Rockford, IL)
5) Discredits Comcast's universal claim to 'committed' or 'commitment' when used in conjunction with customer service and quality of service....
I could go on, but I think the point is made.
Does Comcast have the ability to provide service as they claim? I am sure they do as demonstrated from other folks here on
DSLR/Broadband Reports
typically in an area that is more prone too and has true competition.
I have noted, on more than one occasion, folks on lesser tier plans (Especially when I was on the supposed 16/2 blast)
consistently blew the doors off or MATCHED my typical speed tests
*another note: I am not the only one in my immediate neighborhood that has expressed anguish over the performance of Comcast's 'HSI'

Now I know what some of your are thinking.... so here is Comcast's own internal 'Flash' speedtest @ »68.87.178.6/ 5:33pm
Download Speed: 10866 kbps (1358.3 KB/sec transfer rate)
Upload Speed: 2467 kbps (308.4 KB/sec transfer rate)
Get off that 10866 kbps looks like your getting your rated down speed trash. Because one has to consider the Powerboost percentage. PowerBoost is a little over a 40% increase in the normal 1Mbps for the tier I am on now
2467 x 40% = 986.8 or 0.9868Mbps
Take the download speed 10866 x 40% = 4346.4kbps or 4.346Mbps
Not too far off from my FTP test...
Now you know why I have been rising a stink for the last year and half...cause this just aint right! This has been the norm for me...

Generally deficient given any tier level verses the ACTUAL performance...even for normal browsing during 'normal' usage times despite the marketing media propagated claims of downloading large files 'Fast' With Comcast HSI [sic] with powerboost [sic]...Please define large!?! Apparently large must be between the parameters of the Powerboost [sic] scheme. But then, there are some parts of the Comcasts network that are just plain shitty and apparently will be forever the same no matter what scheme they use. Unless, despite whoever claims, we get some genuine competition here.

Uploaded another TCP pingplotter image from a sample set yesterday afternoon - early evening showing the exact spike that threw my Dennon 1909 AVR into a tizzy. It's been happening more frequently lately. Although I suspected several other reasons other than Comcast for my Dennon spazzing on and off then resetting itself, I just happened to be pinging Microsoft.com using tcp packets when 'Spike' happened and instantly my Dennon went into it's spazz....

| My (Now Comcast) data connection went down on Tuesday, Apr. 22nd. (80 degrees and sunny BTW.) I have been on the phone three times with Tech Support. Each time there is always some minor glitch....Modem not registered, last tech forgot a number, blah blah, but never a solution.
I went to purchase a new modem and lo' and behold, there is not a single cable modem in the Rockford area at any of the major retailers. (BB,CC,Office Depot, Office Max). Turns out that many a Rockfordian is having cable modem issues. Hmmmmm.
I suppose that the the house call, scheduled 7 days later, will find the problem will be internal customer equipment, so I get to fork out an additional $45 for the service call AND buy a new modem.
Congrats on the skyscraper, Comcast.

| comcast Well, went from 10/1.5 to 1.5/1.5 ... went though the online tech help...Sends out service guy...seems they went from channel 80 to channel 73 to split up the users as they had too many and causing lag issues. Seems they put in traps if you dont have cable tv service also. (use Directv - more channels less money then comcast) Trap drops off everything BELOW channel 74...thats why the drop in speed. Some bright comcast person decided to do that...why? Tech takes out trap and I'm back up to 10+ down and 1.5 up...
Take care,

| Debugging Need to capture pings and a traceroute at the time of issue. Also be sure you are evaluating them properly.
1) Packet loss at router interfaces is usually a red-herring. Read:
More info: »Tools FAQ »Why am I seeing so much packet loss in my provider's network?
2) The Boston DNS record is bogus. Based on ping times, this router is really in Chicago. This is administrative and happens sometimes. It is not a real issue. Also and again, loss/latency at a router which is not seen at the end point is not service impacting. | |

trying2help13
@comcast.net
| Fake packet loss "have notice a few folks posted a thread in the forums about a node/router in Connecticut (& other places) dropping packets big time. It just so happens to be one of those nodes/routers that is affecting me in Northern Illinois that I have repeatedly reported on numerous occasions. One in Massachusetts is another that acts up frequently and affects me here." The reason for this is due to the routers being configured to drop ICMP and other user test traffic sent at their interfaces in favor of service related traffic flowing through their interfaces. Believe it or not, it is the standard way all large networks are configured. It does not impact service in any way.
I explained the Boston/Hartford vs. Chicago in the previous post | |

| Re: Fake packet loss I do appreciate the input and I in no way claim to be a expert. I do admit I am constantly in part-time learning mode.
One thing I have noticed is when certain programs I have take longer to sync is when the packet losses are more prevalent. A cool thing about PingPlotter is that it is able send packets using the ICMP using Windows dll, ICMP using Raw sockets, UDP Packets (Unix-Style or targeted [IAX (VOIP) Ping,UDP DNS Query,etc])& TCP (ie: HTTP,etc) All of the above have various customizable features.
I have heard before that the Ma one was misnamed. But that was on the internet!?! I am just stating what the whois servers are saying what they are. If it is an Administrative problem or error...well, need I say more about the Administrations efficiency example set before us? If this is 100% true, then I'll lay odds they were the ones causing the issues that a few folks were complaining about recently in the Chicago area. Maybe its all one big coincidence. Maybe we all should just believe whatever the marketing department and administration says is true...Just a little hard to do when one has been caught in a blatant lie and the hype doesn't match the real life experiences.
Again Thanks.

| Analysing traceroutes said by fishmaster :One thing I have noticed is when certain programs I have take longer to sync is when the packet losses are more prevalent. Try and capture the traceroute at that point. Could be many things and the more data the better. Learn to read a traceroute to help isolate the issue and who you need to contact to fix (not always your ISP)

It is a good tool, but always remember that any packet sent AT the router will be treated at a very low priority vs. traffic passing THROUGH the router. Loss shown on Ping Plotter is only valid when the loss/latency is consistent from a specific hop all the way through to the destination.

Again Thanks. Reverse lookups of router interfaces are not always 100% accurate. It is not done on purpose and mistakes are not a major measure of a network. I've seen these mistakes in every network and they are in now way service impacting.
Fishmaster, hopefully your issues get addressed, but lets make sure people focus on real issues (vs. traceroute anomolies) and the right fix agent is engaged (which may not always be Comcast). Good luck and hope this helps. | |

@comcast.net
| Re: Fake packet loss I don't see an overloaded Comcast element in your data. I did a quick review of the first 6-7 ping plotters you posted and here is my analysis
• 100% packet loss at first hop - non issue and common on CMTS boxes
• X% packet loss at hops along the way, but not at end site - non issue as long as end site is not seeing loss
• Destination unreachable after atdn.net hop - end site issue. Not a network issue
• 65ms response to google on east coast from Chicago - OK
• 45ms response to yahoo in DC from Chicago via L3 - OK
• 62ms response to google on east coast with 10% packet loss - Not OK, but Google has been having issues lately with their upstream ISPs
• 23ms response to a local site on GTEI/L3 - OK
• 32ms response to ihop.org near StLouis - OK
• 87ms response to yahoo on the west coast - OK
I didn't go through every one, but I think you are finding exception to the loss / latency on intermediate hops. As said before these are not real issues and are not causing problems. The only problem I can see is the one you did with Google, but this appears to be a problem with Google and not your Comcast service specifically. See
»[Connectivity] Comcast dropping packets from google/gmail?
»YouTube very slow?
If you still think you are having performance issues, please post a recent ping plotter to the site in question. If you are not seeing loss or heavy latency at the end site, then there is not a network issue (remember latency is also caused by how many miles away the site is - speed of light) | |

| Re: Comcast Assistance Maybe it has to do with the continuous updates to his review which keeps it very prominently toward the top of the reviews. I think that's a good thing. If that's what it takes to get an ISPs attention, then periodic postings about poor service seem acceptable to me.
There was a time when dslreports was a website where you could consistently get assistance and express your opinions. Now it's becoming dominated by fans and employees of the various ISPs who jump on anyone who posts a negative review as if customers' problems are all in their heads. I don't mind satisfied customers cheering an ISP, but many attacks are nothing more than accusations and insulting remarks.
An ISP should clearly specify what they will deliver and what it will cost. They should then have the expertise available to follow through on their commitment. People don't post bad reviews for no reason. They post out of frustration almost always after having tried unsuccessfully to get satisfaction directly from the ISP. It would be outstanding if ISPs actually provided a means to bring knowledgeable technical support to people who suffer poor service instead of repeatedly forcing them to deal with nontechnical phone operators whose only apparent job is to shield the ISP's high end technical people from complaints. Hopefully Mr Eliason will do that in this case (which certainly deserves it). | |

Appears they are sincere in a workable solution in these issues. Thats all I will say about it at this time.

The point of the matter is that he's not getting what he's paying for. There is nothing wrong with demanding that an ISP deliver on their promises. And there sure as heck isn't anything wrong with posting about their failure to do that in a review forum. The best way to make this guy shut up is for Comcast to fix his problem (if it's not too inconvenient for them). In lieu of that, I'd say he has every right to complain regularly where the whole world can see it.
Comcast is great when it's working as it's supposed to, but if there's a problem, they are your worst nightmare. | |

2 edits | Comcast Response The speed test you are running are to the west coast and the east coast. The most accurate speed tests will be those closest to your home. I understand from our conversations that you would like the same speeds when going to other places around the world, but that is not how the internet is designed. The internet jumps you from server to server to get you to the location you are looking for. In Illinois you typically leave the Comcast network in Chicago. I will be happy to assist with legitimate concerns and I do want to make sure you have the right experience. At the same time you need to have the right expectations.
We will review your latest ping plotter data to determine if there is anything we can do to improve your experience based on that. I will be happy to report back here with our findings.

| Speed slow down during peak hours Said by fishmaster: I have been noting a considerable degradation in 'Speed' performance during 'Peak' time. (Generally 2/3rds of the normal using the internet time) Even with the highly media marketing propagated 'Powerboost'.
Apparently the 'Powerboost' works well OFF peak hours. But what about 'Peak' hours? Does it turn off then? Doubt it very seriously. Then why the serious degradation in performance during 'Peak' hours
All cable systems slow down at peak hours. that's because you're sharing your connection wiht everybody that is connected on that node ( usually a couple of hundreds ) . Thats not gonna change anytime soon . only systems that dont slow down during peak hours are dsl and fios ( that i know of ) since they have a dedicated line
complaining about that would be like complaining that your v8 car only gives u 18mpg . | |

| Re: Speed slow down during peak hours said by fishmaster :I understand & expect a lil bit of overhead during peak times. However when the general experience decreasing hits the halved mark and beyond. That is not acceptable. That is a good indication piss poor management, planning & network capabilities. Oversold & Overloaded. Or the DPI crap in the way can't keep up. If the node is capable of ( for example ) 500 hsi customer and 50 more order what do u think they are gonna do ?
that's why it says on the TOS that they dont warranty any speed ( read it im not kidding ) . some isp's wont even troubleshoot it if not really low like dial up speeds 100-300 kbps . At this point i gotta admit it sux to be you because you dont have ANY real options ( i mean u got dial up but that's a downgrade and the pings on sattelite are way over 700 )
If Frank ( which most people online admit is the most helpful guy on comcast) can't help you nobody else can
They are not violating their TOS since you're getting over 5000 at worst . for what is worth i had cable modem before and i know what you're going through when u called and they want you to reboot your pc and reboot the modem etc. I'm lucky to be able to have fios and had Zero outages in 2 years | |

| Maintenance I don't see a single comment about any of your trouble call technicians calling this issue to a maintenance crew. The "blocks" on your TV is microblocking and can be caused by anything from dirt touching the copper in a connector to a bad TV or a bad ground several houses down the street causing extra signal to ingress into your lines.
The most popular ones are VCR or DVD/VCR combos with those cheap RF jumpers in the back that people connect to record TV off of their digital boxes. | |

| Frustrated with Comcast I recently moved over to the Comcast triple play, with Powerboost. Advertised 16Mbps download speeds.
Cable modem install went well at first, nice speed, but phone couldn't be installed due to admin problems. Phone install rescheduled for 2 days later. I made sure to be home at the appointed time. No one showed up, but at some point, my phone went dead. I plugged the line into the cable modem and it was apparent they'd made the switch. It would have been nice if someone had told me so I could retrieve voice mail.
However, the problem is that ever since then the download speeds have dropped to 1.88 Mbps. They came and swapped out the modem, but no speed increase. Someone was supposed to come back out, but Comcast cancelled the call without contacting me.
Everytime I call customer service, I get a different response as to where the problem lies. I realize that it says "speed UP to 16Mbps, but seriously - 1.88 means something is wrong.
I'm hard wired into the modem right now (after one of their "fixes" my router stopped working - router still works beautifully on DSL line).
I'm tired, frustrated, and don't know where to turn next. I had to make the switch to Cable for corporate reasons, and Comcast has a monopoly in this area of NJ (you can either get Comcast Cable or Embarq DSL - none of the other providers are allowed in even though the residents have been fighting it for years).
Any suggestions?

The best thing about my service with Comcast is its reliability--the damn thing just never goes down.
The speed is fast--I consistently get 12Mbps down and with the PowerBoost it can go as high as 23Mbps. I regularly see about 3Mbps up which is really surprising.
I've had to change modems a few times and their people were patient with me and provided good service.
I originally was paying about $44 a month but they recently offered me a combo deal with my TV and it looks like I'm paying maybe $30. Quite remarkable.
The only black eye with Comcast is that they do DNS redirection which sends you to an ad page when you mistype URLs. Fortunately they also make it easy to opt out of this "service" if it bothers you.
You will read many complaints about Comcast broadband service in the forums but remember that the vast majority of people have no problems and since they are the largest ISP by far there will be more complaints.

I've been a WOW subscriber for 8 1/2 years and have been really happy with them. I left Comcast for WOW back then because of constant service issues. Recently there was a post in the WOW forum with a member leaving due to a great deal he got, so I decided to look into it. Well, it was a fantastic deal and I went for it. I have nothing to lose really.
My services entail, Digital tv service with HBO and Starz, 3 DVRs, 1 SD box, 8Mbps internet tier, and phone service, all for roughly $116 a month for a year.
The install was kind of a nightmare. My job should have been easy as all that was really needed was a new drop to the house. All the inside wiring was perfect and working. Just change all the WOW gear for Comcast and we're done. Well the drop went easy and that was it. The phone # wasn't ported over and Comcast actually sent the tech out with a truck full of DCT-6412 Phase 1 boxes, which didn't have RF outputs, as I needed RF out for 2 sets. I was really hoping for DCX-3400s, but they were out of stock at the moment. So the only thing that really went right was my internet install.
I had him leave the boxes as I was going to go to the local payment center and swap them out. What a joke, and I hope someone from Comcast reads this. OPEN MORE SERVICE CENTERS!!!! It's BS that all of SE MI has to go to the one service center in Warren. There were people from Detroit and Port Huron there, what a crock. So after standing in line for 2 hours I was told they didn't have any DVRs that I could use.
I was so pissed after that I called up 800-Comcast and talked to a tv guy. He was really nice and helpful. He had fulfillment call me back and she got my phone ported within 30 seconds. She then also placed a special request order for 3 brand new DCX-3400s to be delivered because that's what I wanted and for all of my troubles. She was supposed to call me back 3-4 days later, well that never happened. So I called back and a nice woman said she IMed her and she would call me back. Well, that never happened either. Lucky for me I have a special connection in Comcast and I decided to exercise it and they were able to get me my DCXs within 2 days.
Overall I'm very happy with Comcast's service and have recommended them to a few other people with this deal I got. Now if only they're get external HDD expansion working on their DVRs to allow me to hook up my 500GB drive that I had with WOW, I'd be in heaven.

Comcast is the only broadband provider for where I live. I have the 12mbit package which was upgraded for free from the 6mbit package I was paying for. Install is usually quick and painless if you have cable hookups at the place already.
I've generally always had decent equipment from Comcast. The past 10 years they've given out motorola modems. About a year ago my 4th motorola modem died for some reason and wouldn't connect. Comcast gave me an unknown brand of modem as a replacement. Using a router, I was getting speeds under 2mbits download. Removing the router eliminated the problem. I wasn't satisfied though. I'd never had an issue using the older motorola modems with any of my routers. I ditched the unknown brand modem supplied by comcast and bought my own motorola modem. Haven't had an issue with the modem at all since.
Comcast has fairly sketchy support. It honestly depends who you talk to. Right now I have intermittent problems with my cable getting extremely poor signals in the evening/night/early morning, but works flawless during the daytime. Two techs have come out when the modem was working fine and tried to blame it on the motorola amplifier I have installed. I removed it and still have the issues. One lady tried to tell me over the phone that it was my ethernet cable. She suggested that some ethernet cables are designed to only send data one way and that was my problem. I'm not even going to explain how stupid that is. I told one tech about that and he just laughed.
Bottom line is, when I don't have problems, my service runs flawlessly. When there are problems... it's beyond pulling teeth to get someone to fix it or even recognize the problem is there. I'd love to love Comcast, but the only thing they really seem to be willing to do is keep tacking credits on my bill everytime I call in. Sooner rather than later I'm just going to ditch them and get the new Quest fiber optic that's being installed right now.

I do not know what people have against comcast. There service is 99.9% reliable. Its gone out 2 times in the last 14 months. Once after a fire and again after a thunderstorm. Its kind of expensive but if combined with a low cost voip provider it can be a little less than you POTS and DSL combined. As demonstrated Below.
I have the blast package (16 Megs Down and 2 Megs Up) which is $72.86 after taxes and Voipo which is roughly $13.75 a month . Combine the two and it comes to $86.61. With Verizon there fastest connection is 1Meg, not fast enough to provide a steady voip connection. So you have to use there POTS which cost big $$$. Anyway 1MB DSL is $19.99 and the POTS with unlimited minutes and three features is $54.99. Plus a unlisted number which verizon charges $1.25 a month for. I'm not sure about the taxes but i remember when my family had verison there was at least $10 in taxes and fees. For example there was a 911 Fee, Line Recovery Fee, State taxes, etc. So the unoffical amount is about $86.23 give or take.
So lets see a very reliable 16meg connection and Unlimited Phone Service with over 20 great features for $86.61 a month or POTS, a unlisted number, and a 1Meg dsl line for Roughly 86.23. That is a 40 cent difference, A lot less than most people think.
Here is a good experience that stuck with me. The other night there were new maps available for gears 2. About 80MB, my friend and i started downloading at the same time. By the time he was at 20% i had already download the maps. And by the time he finished downloading them (about 15 mins later) i had already played all three.
The only bad thing is having to reset my modem every few days to stay at peak performance.
Overall Comcast Broadband is a much better deal than it leads onto be. The only bad thing is the 250 Gig Cap. But its still a little smaller data allowance than verision dsl. Do the math and you will see a 1meg connection running 24/7 at 100Kbps (Top speed based on my buddys connection) for 31 days only 259 gigs, compared to 250 gigs via comcast.
Anyone moving to Santa Maria needs to get comcast and a voip provider. It makes for a much better internet experience. Maybe if verizon looses more and more people they might think about bringing FIOS here in 09. The day that happens verizon will be welcome in my home again. No questions asked.
Update 2/1/2009
After 4 months of lies i finally got my blast speeds. I get about 2 megabytes a second when i download and that's faster than anything i thought was possible worth my current hardware. Ive come a long way from 180kbps DSL. And like i said before with blast and voip its the same price as POTS and DSL, ultimately making this the better deal for value.
Update 4/14/2009
My Blast Price Went Up $2.00 while around the country Blast Prices Are Being Lowered 10-15 Dollars. So since i am now receiving blast and Ultra prices i must lower the value for money from a 5 to A 2
Update 11/26/2009
Had to downgrade as part of my financial budget cuts but really don't notice a solid differnce in speed, with powerboost kicking in every so often no real noticeable speed decreases to be had. My view of comcast has really improved in the last 6 months, im very grateful they are around. I hope to upgrade to 50 tier some day

| as soon as verizon comes hello perki, i'm sorry you had a bad install experince, but what you should have done is called and complained and they would have given you a credit for the poor service, as for jumping to fios , well it sounds like you've had good service and overall experince with us, just to let you know if you go to verizon, they will only give there service techs 2-3 calls a day because they are union . our techs get between 6-9 calls a day, the horror stories i've heard will make you think twice ' i'm not just plowing smoke, you can find this out for yourself, when you see a verizon van on a corner were are there techs usually at the coffee shop or slepping in the van. do the research before you switch.... good luck | |

| Comcast provisioning I had to drop Comcast as my cable provider after suffering through multiple rate hikes a year- for "upgrading" their infrastructure. We never saw the benefits of these rate hikes and the cable form the pole to our house hasn't been touched since it was installed by a previous Cable provider. As far as performance, I believe the last time I checked, my area was being offered 6mb as the fastest with a powerboost which netted about 12mb/sec for 2 sec of download-not a big selling point in my opinion. I even had to repair my own cable drop when a truck going by caught the line from the pole (was sagging horribly after a lot of years). I called Comcast to fix the line(it was laying in the street) but they NEVER rolled a truck. I ended up climbing up on my roof and pulling the cable and securing it to the house. That was the straw the broke things. I quit Comcast and went with Direct-TV. BTW if COMCAST really reads these posts they should know that the on-line tools for COMCAST are so convoluted you have no idea of what you can/should/must order. Some real truthful disclosure would go a LONG way to fix the reputation of Comcast. In ther end Comcast is just as good/bad as the rest of the providers.They ALLhide behind their TOS statements and make a lot of promises they know they won't keep. | |

I love DSLX, but 5mbps is just not scratching my back like it used to. I decided to sign up for Comcast's base tier once my area went D3, which it did a few weeks ago. I ordered online and was able to get a rate of 19.99 per month for six months for 12/2 service, plus a $50 install fee. I thought the install fee was pretty irritating because I took the time to run the cable, but it turned out to be worth the price.
The installer arrived on time and set to work. All he had to do was terminate both ends of the RG6, connect the modem, and provision it. Unfortunately, the modem (a D3 Ambit model) was not being recognized by whoever provisions the modems. The upstream light on the modem was blinking, and the installer could not figure out why. To his credit, this was only his second install using that particular modem, but for some reason he was focusing more on the fact that my computer was pulling down a local address from the modem (192.168.x.x) than the lights on the modem clearly indicating that something was wrong. After a lot of futile motions on his part, his supervisor came over and together they discovered a corroded connector in the cable box across the street. Once that was fixed, I was up and running. My upstream power level is marginal (49-50) but it's been very solid so far.
The speed is good and it is very consistent. Powerboost takes me above 2MBps, but once it wears off I am at 1.5-1.6. It's interesting to note that my max rate is capped at the modem at around 21Mbps down and 3mbps up, whereas I could speedtest at 30/5 on SB5100s pre D3. I guess capping the max burst rate is one way to differentiate between tiers.
Uploads sit at around 250KBps consistent, with powerboost pushing me over 300. I have seen no evidence of any throttling so far. The 250GB cap may become an issue, but I'm trying to alter my habits.
Once my promo runs out I'd imagine I'll upgrade to Ultra or Extreme if I can get a decent rate, as well as sign up for CDV. Well done, Comcast.

25-NOV-2009 Update-
Still waiting for DOCSIS 3 to roll out here. Powerboost at 25dn/2.9up. Sustained at 6.6dn/2.7up. No service disruptions. Running a SB5101 (I own it).
23-MAY-2009 Update-
Things are still good. Was told that DOCSIS 3 is coming in June. I'm happy.
Initial Impressions-
Constant speeds are 6600dn/1100up. With Powerboost I see 29000dn/4300up. Waiting for the free upgrade from 6/1 to 12/2. I use them as my pipe to the net. I do not use their other 'services' (email, portal, etc.).
