<title>[Connectivity] what is unicast maintenance ranging - possibly so</title>
<link>http://www.dslreports.com/forum/remark,26817083</link>
<description><![CDATA[Last week I posted about my unicast maintenance ranging problem.  Today a tech came to the house.  A few days ago my upstream jumped to 56.5 and I called Comcast.

While here the tech (using his equipment) saw the upstream go from 53.5 to 51.  In the morning I had checked my line and it was at 53.5.  He said that should not fluctuate like it did and he went outside and did some checking.

He decided that the problem is in the main line at the street.  The reason none of my neighbors are having the problem is I am the only one coming off that particular part of the pole.  So he is sending a ticket to have someone come out and work on the long lines.

He said it isn't the modem.]]></description>

<title>[Business] Comcast Direct 1, Comcast phone support 0</title>
<link>http://www.dslreports.com/forum/remark,26839879</link>
<description><![CDATA[I tried Comcast phone customer service to handle erroneous billing. After 2 weeks no result. Yesterday I tried Comcast Direct. Some additional information was needed, provided last night in a 2nd post. Today, got a call from Comcast and the problem is resolved.

Thanks Comcast and thanks dslreports. 

No cable modem bill for me.

<title>[Speed] Albuquerque Speed Loss in 87104 area</title>
<link>http://www.dslreports.com/forum/remark,26845322</link>
<description><![CDATA[Since about 1:30pm yesterday I have lost most of my download speed.  I have the Blast home service which is supposed to give around 16Mbps down and about 4Mbps up.  I recently installed a new Motorola Surfboard SBG6580 which has DOCSIS 3.0.  Since yesterday my down speed has been about 1.5Mbps and 4.5Mbps up with a ping in the range of 65-125 which is normal for me.  The up speed is also normal.  It is only the down speed that is effected.  I was wondering if anyone else is having the same issue?  I had a technician at my house about 15 minutes ago and he could find no connection problems.  Is there an upgrade happening that is effecting speeds?  I could get no answers on the phone and as I said the tech found no problems at my house. ]]></description>

<description><![CDATA[Why does Comcast/xfinity insist on sending these emails?  I imagine they garner a ton of business from unsuspected noobs who believe this sales pitch, directing them towards a paid service.

Admittedly the first time I received this email I panicked.  I'm not new to computers, nor fighting/repairing virus infections.  Ran all kinds of scans trying to find a virus that simply didn't exist.]]></description>

<title>[IPv6] Benefits of IPv6</title>
<link>http://www.dslreports.com/forum/remark,26818593</link>
<description><![CDATA[I have been following some of the threads about IPv6 and don't really understand the benefits other than what I have read that with IPv4 you can have a max of 4.2 billion IP address as with IPv6 you can have 340 trillion trillion trillion address.
After reading some of the comments, there must be more to it than just more addresses.
Both my modem and router are IPv6 capable, but will there be any benefit as far as speed and reliability on the internet once IPv6 is rolled out to everyone?
Thanks

<title>[Business] Switching modem / Well over provisioned speed</title>
<link>http://www.dslreports.com/forum/remark,26860688</link>
<description><![CDATA[  I am a new Comcast business class customer.  I was provided with a SMC gateway but prefer to use my own modem and router.

  I have a SB6120.  What is the easiest process to switch to using my own modem?  Can I just plug it in and go through the process in the walled garden or should I call customer support?

  Also I am paying for 22/5 service but have been over provisioned, from reading this forum and from others that I know with the service this is common.  Will I lose these speeds if I switch to my own modem?  I'm currently getting 85+/12+ speeds, is this SpeedBoost? :o]]></description>

<title>Comcast- 1,100 Feet of cable for 3 Houses ???</title>
<link>http://www.dslreports.com/forum/remark,26839370</link>
<description><![CDATA[I am on a one man mission to get comcast installed at my current residence , comcast would have to run about 1,100 Feet for three homes. i know for sure me and my neighbor would sign up (the first two homes). I have already gotten a quote from comcast of 7,500 dollars which i thought was quite ridiculous. Maybe i am wrong, but i mean whats the big deal ?  I have attached a simple image that indicates the most plausable route of the cable to be laid. The red line indicates the new cable that needs to be laid, the black is just me trying to cover the street names so the world doesnt know where i live.  ]]></description>

<title>Comcast says I don&#x27;t have DOCSIS 3 - somewhere in the USA</title>
<link>http://www.dslreports.com/forum/remark,26850868</link>
<description><![CDATA[When I called Comcast and asked if DOCSIS 3 is available in my area I was told not yet. Yet my speedtest.net speed is around 31-mbps down and 5-mbps up. Also when I login to my account to see what packages are offered, the top package is the 50-mbps down / 10-mbps up. Isn't the 50 / 10 speed DOCSIS 3?

I upgraded my internet / telephone modem to the latest Arris modem in anticipation of DOCSIS 3. Would any of the lights on my modem be blue if I did have it?]]></description>

<title>Best Buy Comcast xFinity eMTA DOCSIS 3.0 Modem Unboxing</title>
<link>http://www.dslreports.com/forum/remark,26853439</link>
<description><![CDATA[I recently purchased and installed the EMTA Arris 722 DOCSIS 3.0 voice modem that Comcast is selling through Best Buy for $149 in my area (McHenry, Illinois). I wanted to avoid the monthly $7 charge in my area. I took some unboxing pictures and posted it on my blog. I always find it helpful to know what your really going to get in the kit.

Feel free to check out the post with all the pictures and details here:

Hopefully, it helps you make the decision if this is the way you want to go. For me -I hate paying rental fees for equipment that shold last a long time.]]></description>

<title>Comcast Seattle Problems</title>
<link>http://www.dslreports.com/forum/remark,26852061</link>
<description><![CDATA[Anybody know what's been going on with Comcast in Seattle lately... I know we had some wind storms and power outages but that aside problems have persisted even when the weather is fine.

It might be working during the day (like it is now with speeds where they should be) but then at night there's almost always problems.

Just a few examples...

Mon 1/2... Late afternoon connection deterioration. Called in but no outage or reason why.

Fri 1/13-1/14.. Friday night/Sat Morning outage... called in the CSR tried to tell me my modem was the problem... he sent packets out and they didn't return. Then magically everything was working again Sat afternoon!

Fri 1/27... I called in and got a message the outage was due to commercial power outages.

Sun 1/29... Speed deterioration & connection issues again but no reason as to why when I called in.

Thurs 2/2... Then last night the upload speed died. The speedtest wouldn't even run it. I took my router out of the mix and power cycled the modem for a direct connection and same result.
 
I ran pings on the DNS servers (they recently switched to 75.75.75.75 & 75.75.76.76) and I was getting 30% packet loss on one and 60% packet loss on the other. I tried the old ones (68.87.85.102 & 68.87.69.150) and they're spotty as well with 40% & 16% packet loss.
 
In every instance the web browsing gets noticeably choppy, it hangs, loads fast, then hangs, loads etc. Running ESPN (POWERED BY XFINITY!) & Netflix on XBox yields the same up and down erratic quality issues in the picture.

1/23... I JUST HAD a tech out here to check the connection inside and outside... ALL GOOD, he changed out a few old connectors, that's it.
 
On the Comcast board a few folks from eastern Wa and outside the state were getting terrible pings to Seattle. It's pretty sad that the connection into and out of a major hub city is so plagued by inconsistency, problems and overall erratic quality. It makes for a poor Xbox experience whether it's streaming video or trying to play competitively when you're almost always lagging on an erratic connection.

This is what they call an UPGRADE?! This is progress?!

The big news they put out is how speeds have been upgraded... and yes my download speed did go up from 30MB to 35MB... Upload is still the same around 5-6MB but it's the overall consistency that seems to be a constant problem.]]></description>

<title>[Signals] Acceptable Corrected &#x26;amp; Uncorrectable Error Levels</title>
<link>http://www.dslreports.com/forum/remark,26827683</link>
<description><![CDATA[Hello,

I noticed my corrected and uncorrectable errors are building on my modem status page. I reset the error counter and attached the results from the last 24 hours.
Is that considered acceptable or is a ticket in order?

History: In Oct/Nov, a CC tech replaced all my connectors and splitters, my aging drop was replaced (which helped immensely), and tech informed me maintenance would be checking the local plant.

Thanks!]]></description>

<title>[Connectivity] Vicious packet loss, mainly upstream, for weeks.</title>
<link>http://www.dslreports.com/forum/remark,26804824</link>
<description><![CDATA[For the last few weeks I've been experiencing packet loss (mainly upstream), ranging from 2% up to 40% with jitter levels between 30-150 (measured at pingtest.net) especially between 7:30pm est and 3:00am est. At my absolute wit's end with this, I'd rather not go through the hassle of switching ISPs, but its the only option if this issue isn't resolved in the next few days.

All my vitals, both upstream and down, read good (29.1 upstream snr according to customer service). Using Moto SB6120. Only had Comcast at this residence since late October.

My best guess, with just my a+/network+ cert is it feels like the node I'm hooked into has some technical issues with upstream channels, and is just getting blasted into oblivion during peak times.]]></description>

<title>First time I have packet loss and high jitter</title>
<link>http://www.dslreports.com/forum/remark,26743280</link>
<description><![CDATA[Every now and then I use speedtest.net and pingtest.net to see the speed/quality of my internet.

Ever since I had Comcast internet (October 2010-present), I have had "Grade A" results on PingTest.net.  Today, however, I was surprised to see some packet loss and higher jitter.  My first grade was a "C", which had packet loss.  I tested again, and I had no packet loss, but my jitter was still high, so my grade was a B.

The ping also seemed higher than usual. 

I have never had this problem before in the 1 year and 3 months I've had internet with Comcast.  The signal levels on my Arris TM722G modem are:

Downstream 1: -1.4dbmv SNR: 37
Downstream 2: -1.8dbmv SNR: 37
Downstream 3: -3.2dbmv SNR 36.8
Downstream 4: -3.2dbmv SNR: 36.1

Upstream: 51.2dbmv (was around 48 a few days ago)

Do you think this is an issue involving my signal personally, or do you think it's an issue with Comcast?  It is Sunday at 2:40pm where I am right now, so maybe there's a lot of traffic on my neighborhood node?
