I am going to post a forum thread from Comcast! Please anylyze comcast is doing QAM256 upgrades all over the country, they are breaking some clean network areas while other not so good copper networks are breaking. Read on...
I am running on Comcast out of Independence, MO. I have been experiencing the problem of my internet connection pausing every 5-10 seconds. Sometimes long enough that the server times out. I upload to three different sites on a regular basis and this has made uploading even the smallest files nearly impossible. Also, since I am seemingly not connected for short periods of time, I have to click links two or more times to get the page to load without getting an error page.
I have called Comcast twice. First they said it was Zone Alarm causing the problem. I completely uninstalled it and had no better results. The second time, they said I was experiencing "packet loss" and would send out a tech to check into the problem. The trouble with that is I can't get a tech out until a full seven days from now! Bummer!
Anyway, I ran a packet loss test at dslreports.com and got the following results:
Simple ping loss check (10secs of 40byte packets two per second)
~Loss = 65%
~Min Latency = 40.6ms
~Avg Latency = 45.6ms
~Max Latency = 53.9ms
~Pass/Fail = FAIL
Low Bandwidth Stream (10secs of 56k/bit ping stream 512byte packets)
~Loss = 100% - Unknown Reason
~Pass/Fail = FAIL
Medium Bandwidth Stream (10secs of 128k/bit ping stream 512byte packets)
~Loss = 51%
~Min Latency = 926ms
~Avg Latency = 2617ms
~Max Latency = 7995ms
~Pass/Fail = FAIL
Your first hop ping (Stream of 40byte pings to "IP")
~Loss = 0%
~Min Latency = 31.9ms
You are 8ms to your first hop!
~Pass/Fail = PASS
This is mostly all greek to me , but what I do know the difference between PASS and FAIL and I got three FAILs out of 4 tests. What could be causing this and is there anything I can do to fix it before next Thursday (when the tech is scheduled). It is absolutely driving me insane.
Thanks for any advice.

Ok you are NOT ALONE! Something is going on in Independence, I do not know what, I am a network engineer, and have repeatedly reported this problem. It has been believed to be a firmware upgrade that happend a couple weeks ago, this is my own guess. Me any my friend in Blue Springs 10 miles away are getting the same exact problem as you, only it's not as bade probably because our modems are brand new docsis surfmodems. But before i got a surfmodem I had a old first generation Docsis modem which was being horrible. Apparently there is a router huge router with 80,000 clients and a bunch of nodes(cards) in our area, this includes Independence, Blue Springs, and who knows where else. I do know the tech that came to my house said last week there was a software upgrade when my modem started all this. I was litterally online with my friend in Blue Srpings when this maintenance started. The modems both of ours went down, and came back up 30 mintues later ever since then the problem has incurred. I had some people do some pings from the outside, the only place from the outside you cannot ping is this router (local). The problem seems to be local and I hear reports of splices,(new areas serviced) and software upgrades (firmware upgrades to router?). All i know is I have had numerous people try(attempt) lousy attempts to help me figure out this. Tonight though I spoke with a person named Jared that is supposedly a senior customer service tech, and he thinks he is seeing this from different areas. Is it possible that firmwares are taking place city by city, or did the maintenance just have a problem or a buggy firmware upgrade? I don't know however the problem is local and there is no doubt they need to fix it I hope they do, I think as many people should call complain and get credits to their accounts in the mean time like me. Another thing to consider is this article, you see the problem only seems to be breaking old modems that cant handle this, and latency on newer modems. On newer modems it is making games, IP phones, and Remote or any socket connection unbareable, and from I hear this is not a Local only thing happening, is comcast changing something? I then find this article hmmm I wonder....

You're right!! It is not a local problem and it seems to have started a few weeks ago here in Eastern Massachusetts. I'm still trying to get comcast's attention on this, but I haven't had a lot of success.

HI i live on the edge of Independence/Blue Springs and having the exact same problems.The node for the whole area is in my backyard. About 3 1/2 weeks ago there were like 5 guys working on the node with a QAM256 upgrade to it.Every since then internet gaming is unbearable.packetloss/disconnection. I have comcast pro and have been a comcast customer for 4+ years and never had any serious problems till this qam256 upgrade.Most people who are gamers will see this problem right off.Anyways i had a tech out here last week and thats the info i got from him.He told me the problem would be taken care of before the week is over.Well here it is another week gone by and no solution.Called them back today and now there sending another tech out to see if he can see what the problem is.
im looking at my modem log right now and i see this

These are my logs..... seems we have the same problem great INFO! call and report this always ask for supervisor, and ask for the supervisors supervisor, until the supervisor says I do not have one. That's what I did to talk to anyone technichal.

Well its happening all the way over in Oregon too. On Tuesday (7/27) night all of a sudden my connection would timeout. This would last from about 5 - 10 seconds, then reconnect. I would be reconnected for about another 20 seconds and then the whole process would start over. It defiantly seems to have a continuos pattern which has now lasted non-stop for 1 week. Ive reset my modem multiple times, checked for viruses, installed a firewall app to make sure that there was no incoming attacks, got all the microsoft updates, etc. etc. etc and it still timeouts in the same pattern. I havent called Comcast yet because I am pretty sure I am going to get the run-a-round like everyone else. Nothing has changed on my end - from the cable line out side my house, to my PC in the last week. Sending some dude out to "check things out" is a waste of time. Is this similar to what you have been noticing?

I think I'm having similar problems as well out here in Southern New Jersey, the weird thing is that when I go gaming, pinging a server gives back a decent ping, around the 50s or 60s, but once in game I start lagging as well. When not gaming, the internet is very slow and downloading is very spontaneous, sometimes I start downloading at 200 kb/s only to have it later plateau at 40 on numerous sites, or sometimes just completely stop. I've also done a few bandidwith tests and I don't remember the exact numbers, but they aren't too great. I thought it was just something with my network or my house, but it seems as people around the country are having these problems.
Dang, this seems to be covering a wide area. I'm in Norcross, GA (near Lilburn) and I have been having dropped connections, packet loss, and lag. My dropped connectivity began in July. The dropped connectivity issue still happens every few days, but not as often as it had been (once a day or multiple times a day). The packet loss and lag are newer problems that I noticed after the dropped connectivity problem began clearing up. I haven't changed my network setup and with all these posts from folks with problems similar to mine it seems like the problem lies elsewhere. It would be cool if comcast had a more informative page (like the one Mindspring used to have back in the day) with scheduled repairs and known issues than their "network health" blurb on the support page. If they know that is an issue it would be nice to know that they know it is an issue and that they are planning on doing something about it. Every call I have made to tech support has resulted in no real information.

It seems as though the smart dudes out there have figured out the problem... but what is the solution?
Modems?
I'm currently using a motorola SB5120, and running a SNR of 33dB.. and I'm getting lag spikes just about once a minute, of pings ranging anywhere from 1000 to 9000, across the board.
I'm thinking about running out to get an RCA today... see if that helps any...
People who have HAD this problem, which modem did you use/get to solve it?

Getting the same problem in Vancouver WA just north of Portland OR. At first I thought it was my router but now I see it's my connection. I think I'm getting a little different problem. My connection is solid for about 15 minutes and then it will just freeze for 10-15 seconds. Playing games is possible but pretty annoying to see it freeze like that and then I know I'm dead. It's funny because I can time when it will freeze next. I check and sometimes I can say okay guys wait for 30 seconds I'm going to freeze and then I freeze. Just like clockwork.

Well everyone I am the one who has been spreading this post. I am soon going to take this and much information and start a website petition. The problem has come because of the QAM256 upgrades around the country they are doing from area to area. The QAM256 upgrade may work on some areas and not others. What the QAM256 does is upgrade thier routers to utilize more bandwidth, and this might be a good thing for them, "offer more bandwidth or customers" they are breaking us in the process. QAM256 basically fits all the packets closer together so it is much more prone to spikes and other problems, I have heard some reports about RCA modems dealing with the problem better, I would like to know if anyone can deal with this. I plan on starting a petition website and getting some signers and information on it, I also plan on sending a letter to HQ Comcast with lots of information about how the system ran great 2 months ago when they were on QAM64 (packets farther apart). You guys this is a money decision and it is ultimately out wieghing us as customers, do not think for a minute that they are not aware of the problem, they are fully aware however its not just jump and replace millions of dollars in time, and hardware. They are choosing the bug and proffit over good service. I personally want to keep my cable modem which is why i choose to fight. DSL, Satellite, and Dial Up are second par when it comes to speed, gaming, and over all internet experience. That thick Coax cable just simply is the best American thing we have for internet now, and I choose it, but I also choose not it to a half but it to it's full and so should you.
Here is some contact information from comcast they do not want you to have. Please make some noise report this forum, and put a end to their ****.
Service number: 18776373128 Senior level support (Jared Ext 5014 he is well aware of this problem yet he says nothing can be done.) Supposedly the manager of all service here is by Nichole Daske try to get in touch with her she is the head honcho there.
Now i know you wont wanna do what I will ask you, but please do it anyway as I am.
Write a letter explaining this problem and how it affects you, when it started and some information like this forum supporting your not the only one to..
Steve Burke (CEO)
1500 Market Street
PA Pensylvania 19102
guys this is Comcast HQ, Steve Burke is the CEO, demand this be stopped or you will not only stop service but spread the truth as to what is happening. Use your threats it's your right as a un happy customer. You have the right to demand correct service which you are paying for. Stand up and put a end to corporate stupidity. |
