<title>[Speed] Blast!, 2mbps upload?</title>
<link>http://www.dslreports.com/forum/remark,20853499</link>
<description><![CDATA[I've had the blast tier for almost 2 years now and people recently have been talking about them getting upgraded to 2 mbps upload, I test my connection and am still showing 16 down and 1 up. I am in a FiOs zone in a town in south jersey called Audubon if that makes any difference, what do IO have to do to get that 2 mbps upload, do I have to call comcast and notify them? Thanks for your help.]]></description>

<title>What MTU is optimal for your NIC?</title>
<link>http://www.dslreports.com/forum/remark,20836529</link>
<description><![CDATA[I'm using Comcast with a DLINK 4300.    The MTU inside the DLINK is set to 1500.

The reason I ask is when my NIC is set to 1500MTU I get 1800kbps on speedtest sites and 275KB/s UPloads in real world FTP tests.  When I change my NICs MTU to 1472 I get 3000kbps on speedtest sites and 400KB/s UPloads in real world FTP tests (which drops off to 265KB/s after powerboost runs out.

The only downside I have found with 1472MTU is occasionally a 3rd party POP server times out and gets stuck on the same email.]]></description>

<title>Canceled Comcast, but still getting billed?</title>
<link>http://www.dslreports.com/forum/remark,20718948</link>
<description><![CDATA[Hi All,

I canceled my Comcast service (HSI and TV almost a month ago [June 2nd]).  That was the day I returned all of my equipment, and called them.  Right now I have a bill that's due tomorrow for June 1st to June 30th, but I'm supposed to be getting money BACK because they charged me in advance.  I called them and they STILL haven't disconnected me at the tap -- I just tried my TV and the basic cable TV still works.  I'm assuming they're going to expect me to pay the bill?  I've called them about this several times, but haven't been able to get a straight answer.  They keep giving me the wrong numbers that I'm due a check as well -- once it was $17.59, and the other time it was $12.52.  I have a feeling the operators are just making these numbers up as they go along..

Is there any kind of direct phone number I can call to get this taken care of?  I'm worried they'll send out a late notice and hit my credit if I don't pay the bill tomorrow, even though I canceled at the beginning of the month.  Any help would be great..]]></description>

<title>Post about PowerBoost and other speed increases here</title>
<link>http://www.dslreports.com/forum/remark,18769382</link>
<description><![CDATA[Continued from ---> http://www.dslreports.com/forum/r17991756-Upload-PowerBoost-See-Where-Its-At  

All discussion of PowerBoost belongs in this thread.  Please do not start another topic about PowerBoost without prior mod approval.

This is also the place to discuss PowerBoost in general, to avoid filling the forum with PowerBoost threads.  Thank you for your cooperation.  :)

What is PowerBoost?

Actual speeds vary and are not guaranteed. PowerBoost only available with Comcast&#146;s 6.0/8.0 speed plans and above. PowerBoost provides bursts of download speed above the customer&#146;s provisioned download speed for the first 10 MB of a file. It then reverts to your provisioned speed for the remainder of the download.

See also this post.

If you are noticing increased speeds, talk about it here until a determination is made whether it is PowerBoost, Blast! or some other officially-offered by Comcast reason.  See this topic ---> http://www.dslreports.com/forum/r19743582-Awesome-Speeds-Anyone-Else-Getting-This

If you simply want to discuss something about speed tiers or ask a related question, post in this thread as well.

The object is to leave space in the forum for topics other than speed discussions.


Please post in this thread if you notice PowerBoost upload speeds have arrived in your area.

<title>[Connectivity] Has comcast dropped L3 in Florida?</title>
<link>http://www.dslreports.com/forum/remark,20854222</link>
<description><![CDATA[Comcast ran Cogent & Level(3) out of their Miami POP, however, it's recently switched 100% to Cogent, it appears.

Knowing that a Cogent connect is about half the price of L3, I'm wondering if this could be a move to save money?

This is disconcerting as we're now having to go through Chicago or DC to get anywhere, and our VoIP jitter just went from +/- 3ms (unbelievably good) to +/- 25ms.

Thank you in advance for any suggestions!]]></description>

It use to go directly from Seattle to Dallas, giving latencies of around 57 ms.  But now, it goes thru Denver first, adding 20-300 ms.

<title>3 Years of Upload Dropping - Severe Packet Loss</title>
<link>http://www.dslreports.com/forum/remark,20789537</link>
<description><![CDATA[OK...

Before you read anything, check out this Line Quality Test:

http://www.dslreports.com/linequality/nil/2406845

You'll have to pardon my ranting, but this has been a problem for a LONG time. If Verizon had run copper in my neighborhood, or if/when they ever run FiOS, I have decided long ago, that I will be jumping ship from Comcast, because of the horrific experience I have had with them. But unfortunately, my only current broadband option is Comcast. (Cost for Satellite or WISP is prohibitive, although I have considered it.)

To Recap The Issues:

1- I have had to cancel my 3rd party VoIP account, because my upload signal regularly dumps.

2- Online gaming is virtually impossible, because although my down-pipe is fine, when I lose the upload, I lose all ability to act within the game environment, regardless of what game it is.

3- I had to cancel Comcast Digital Cable (TV) because of this upload issue. If I tried to order On-Demand events, the system would freeze, because I couldn't SEND information through the system. Regularly couldn't change channels. This is simple stuff.

4- I host a personal/non-business related website. I regularly cannot upload information.

5- I cannot use services such as Skype, Ventrilo or Teamspeak, because my upload drops out.

6- Chat programs like Trillian, Yahoo IM, MSN Messenger, AIM are spotty, because I can receive messages, but very often cannot send.

7- E-mail is a hassle, because sending can be spotty.

It all started when I moved to this townhouse. (2005) The development is brand new, all the lines and hardware are brand new. Within the first month I noticed that my upload pipe was, shall we say, "unreliable"... It's not that it wasn't fast enough to satisfy my needs... It's that it would on certain intervals, drop to ZERO, take a few minutes, cycle, and come back. It took 3 tech vists just to convince them that the problem wasn't any of my network hardware, and they finally told me "the upload signal at the box (at the corner of the street) was so low they almost couldn't measure it."

They then dug up and replaced the main line that ties all of the units in my building to the service main. I can say, they did NOT bury it deep enough, because I can SEE it in my front yard. They also, and I quote from another tech "used a gauge wire they only normally use when they have to run very long distances, which is odd, since they are only running about 120 feet." 

I gave up complaining about this problem about a year ago, after a Supervisor Tech came out and told me it was a quality of service issue, and that my best bet was to try Verizon. The result of his visit was as follows:
I explained the whole deal to him, and he headed outside. About 15 or 20 minutes later he came back in the house to tell me:

1 - the problem is 100% outside.

2 - the problem is somewhere past the cable box on the corner.

3 - he said "the upstream is WAY too high" (remember, i am spitting back what he said, i have zip idea what that means.)

4 - he said "the power rating has noise/distortion, and does not maintin a constant signal. even if it were a weak signal, it should remain a constant weak signal. something is wrong, if it's all over the place like this." (remember, i am spitting back what he said, i have zip idea what that means.)

5 - he left his ticket open, and put in a, SRO for a Line Crew to come out, because the problem definately exists somewhere behind the box.. whether it's up a pole or undergound, he obviously couldn't say.

6 - he said the wiring at my house was done by a blind person, and he re-worked it, although that wasn't going to FIX the problem, but should help with performance once the problem is fixed. (he said that someone was using a 3-way splitter as a junction and left the other 2 ports open, so he replaced it with a "barrel"..)

NOW... in 3 years, I have had probably 15-20 service calls, two SRO's for Line Crews.... and as I am typing this, I have my second tech in less than a week scheduled to come out, as well as another SRO for a Line Crew.

It's interesting, but I am not the only person in my neighborhood who has this problem. I live in a townhouse community, and if you drive through the development, you will see a total of 3 satellite dishes on the buildings. In probably over 100 units. MY building is the only thing that feeds off of the line on my side of the street, and EVERY SINGLE UNIT in my building (10 units) has a satellite dish on it, because we all have the same problem. I am apparently the only one who complains about it.

Here's an old post here on BBR when I was pursuing the problem, and as fed up, as I am now:
http://www.dslreports.com/forum/r18026589-Comcast-passing-the-buck-to-the-customer-for-bad-service

If anyone has any suggestions, I am ALL EARS!

Thanks, and sorry for being ranty and long-winded.
