[Speed] Slow Speeds and gaming issues.

SW Chicago Suburbs http://www.dslreports.com/forum/remark,18161220 anon : I am in Highland Park, IL, and I also have an SB5120 (which I just got recently). I previously had a D-link DCM-202. I get very similar problems to the ones you describe with the connection, and I get a TON of intermittent problems on the upstream. But all speed tests, pings, etc.. come out perfectly fine. I have no idea what is going on but I don't recall any of these problems with the DCM-202, but it's power adapter melted (literally).

I have had many techs out, they replace my wiring, give me a direct line to the cable box outside, only one splitter in the path which has been replaced a bunch of times, did nothing. They just fixed a problem with noise and spiking power levels on my line, and now my downstream power has settled down and all things reported at 192.168.100.1 are perfectly normal, but I still have this damn upstream problem. I think it is the SB5120. I just ordered a SB5100 off ebay, supposed to be the best cable modem.]]> http://www.dslreports.com/forum/remark,18161220 Thu, 12 Apr 2007 19:17:43 EDT Re: [Speed] Slow Speeds and gaming issues. SW Chicago Suburbs http://www.dslreports.com/forum/remark,18160872 Quaoar : What you need to do is simple: pester the CSRs until you get satisfaction. Note that you are paying for a business-level account with a premium charge, and Comcast must make it perform to your satisfaction. Ask for a credit for every day you note performance problems, and keep a diary of the issues. Sooner or later (hopefully, sooner) you will get a tech's tech and all will be well.

I've been in the same situation as you with an intermittent connection whenever the wind was up at my house. It took serveral calls until the tech that showed up the last time fixed the loose connection on the drop to the house from the overhead line.]]> http://www.dslreports.com/forum/remark,18160872 Thu, 12 Apr 2007 18:08:40 EDT Re: [Speed] Slow Speeds and gaming issues. SW Chicago Suburbs http://www.dslreports.com/forum/remark,18159713 joeyfry : Well say what you will. Degree from U of I, thank you! And many advanced math classes, yes. I'm not here to argue intellect with you. I'm here to solve my problem.

Would you like to know about my setup... well, here it is. A single line coming into a newly constructed house that plugs directly into the SMC 8014 modem (no splitters - RG6 cable is about 6 feet long from where it enters my house to the modem ). The modem directly feeds into my Windows 2003 Server (that again, has been using the same setup as it has for the past year, no rebuilds). Another line from the modem feeds my Linksys WAP (and that feeds the rest of the house - 1 desktop and 1 laptop). There isn't a rats nest of cables.

Day 1: I called Comcast business support and they sent out a residential tech. He of course had no business class modem, but he dropped me a new line (box to house ~ 80'). Problem still not fixed.
Day 2: Tech brought a business class modem and hooked it up, installed new configuration file to it, to no avail. Ping/Download times still crap.
Day 3: Line tech comes out to check signal at box. Result: Packet loss and faded signal. Tech says he will escalate problem so that another tech comes and checks the line with "better equipment"
Day 4: Mr. "better equipment" tech leaves a note on the front door: "Your problem fixed!" Elated, I run down stairs and try pinging/loading google.com. Result: Still takes 20 seconds to pull up the website.

I'm leaving out the many hours I've spent on the phone with Comcast. Most of the time they tell me there is nothing they can do even though the tech that can out on day 3 wrote on the ticket "obvious line issues".

What more info can I relay in this message board what will assist the almighty Comcast company to help me resolve this issue? Please tell me and I will post whatever I can.]]> http://www.dslreports.com/forum/remark,18159713 Thu, 12 Apr 2007 14:32:05 EDT Re: [Speed] Slow Speeds and gaming issues. SW Chicago Suburbs http://www.dslreports.com/forum/remark,18151027 joeyfry : I don't have to show them a line test... I can have them bring over their laptops and have them pull up google.com. When they ask why it takes 30 seconds to do so, I'll simply say, "I have Comcast"]]> http://www.dslreports.com/forum/remark,18151027 Tue, 10 Apr 2007 23:15:31 EDT Re: [Speed] Slow Speeds and gaming issues. SW Chicago Suburbs http://www.dslreports.com/forum/remark,18150576 CableTool : I didnt say it did answer why. Just stating that pointing to THAT loss and stating it is "obviously" causing your issues is inaccurate.
Maybe you can teach the other computer engineers how to read a simple line test chart now!! ;)

Well CableTool, that still doesn't answer why I am experience all this packet loss all of a sudden with my connection going up and down. My connection was fine for a year and one day in February all went to hell. I changed nothing on my end therefore it is a Comcast issue as far as I'm concerned. Believe me, if I had another option where I live, I would have exercised it!]]> http://www.dslreports.com/forum/remark,18146699 Tue, 10 Apr 2007 09:31:38 EDT Re: [Speed] Slow Speeds and gaming issues.

Also, please enlighten me how packet loss at the same hop isn't the same problem? Enlightening answers only or don't bother posting. And I posted my concern to two others so that they can contact me if/when they get their issues resolved!............

I'm a Computer Engineer so I understand how to read a simple line test chart.
Because as previously stated by NerdTalker, the routers are denying the ICMP packets showing as loss. You will ALWAYS see loss on those. That is really the only similarity between you and the OP. You both have Comcast and their routers deny most pings.

Your issue is much more local as all the real loss is at your modem/house/drop/line etc.

Really, stop hijacking everyone elses thread by posting -"YEAH! ME TO! here is all my info and 3 more posts about it! Now.. what was the OP trying to say again?"

If you have a concern start a thread with all the relevant information requested and get a dialogue going.

I got zero intelligent feedback from Comcast employees both on the phone and on site. I'm a Computer Engineer so I understand how to read a simple line test chart. So if you are such an expert, I would much rather be enlightened than swore at. I'm not here to argue as the board rules state. All I want is for someone at Comcast to fix my problem.

I live on the soutwest side and I am getting similar problems. For the past month I have been in contact with comcast and they claim that it is not their problem that the hop from att.net to comcast.net is dropping packets. Check out my post and test results and compare them to you. I'm sorry that I offer no support, I would like to know all who is effected. Do you have a business account? My neighbor has a normal residential account and his signal is fine, he claims.

Also, your problem is not related to the original posters problem. It is completely seperate with a seperate cause. Just wanted to point out that there is no correlation between your two problems. None at all!]]> http://www.dslreports.com/forum/remark,18145789 Tue, 10 Apr 2007 01:57:04 EDT Re: [Speed] Slow Speeds and gaming issues.

The problem is not an ATT router dropping packets to comcast. You posted this same crap on another post, do a little reading before you make such ignorant posts, this is as basic as it gets.]]> http://www.dslreports.com/forum/remark,18145786 Tue, 10 Apr 2007 01:55:07 EDT Re: [Speed] Slow Speeds and gaming issues.

SW Chicago Suburbs http://www.dslreports.com/forum/remark,18138301 steelhead78 : Do you mean that you have tried a wired connection to your router, or an actual direct connection, modem to computer? If not, could you try just to eliminate the router from the equation? Remember to reboot the modem after unplugging from the router and previous to plugging into th computer.

SW Chicago Suburbs http://www.dslreports.com/forum/remark,18137938 Nerdtalker : Well, just from looking at your linequality test, it's pretty obvious that there are some definite packet loss issues to your modem.

The hops before that (which are Comcast) really don't indicate anything, since ICMP traffic has very low priority now.

What lights remain lit while you have the intermittent connectivity? Do your signal levels vary at all, keep a close eye on downstream SNR and power. Post a copy of the modem logs, as well.

SW Chicago Suburbs http://www.dslreports.com/forum/remark,18137774 anon : honestly it could be a million things. Yes it could be a bad amp, or a combination of a million other things. hopefully the line tech will fix it, but I wouldn't count on it, they have a bad track record with your type of problem. (not their fault usually it's comcasts managements fault) anyway, if it's not fixed after 36 hours call and complain.]]> http://www.dslreports.com/forum/remark,18137774 Sun, 08 Apr 2007 18:08:33 EDT Re: [Speed] Slow Speeds and gaming issues. SW Chicago Suburbs http://www.dslreports.com/forum/remark,18135325 Ay_Gov : Well, I had a tech out on Thursday evening and he said that my signal at the tap was weak and scheduled a line tech to come out and possibly replace an amp (24-36 hour time-frame so I've no idea if the line tech has been out yet or not). Now, I've done a bit more investigating into the problem and what appears to be happening is that during a download the bandwidth will drop down to 0 kB/s for about a second or two and then ramp back up to normal speeds and continue on until it drops off again a short while later. Are these symptoms consistent with a bad amp on the line and if not does anyone else have any idea what it could be??]]> http://www.dslreports.com/forum/remark,18135325 Sun, 08 Apr 2007 02:07:25 EDT [Speed] Slow Speeds and gaming issues. SW Chicago Suburbs http://www.dslreports.com/forum/remark,18119573 Ay_Gov : 1) Your location: Palos Hills, IL

2) A description of the problem.

Slow speeds in varying degrees. It goes from max speeds to the speeds I've posted below. Online gaming has become unplayable over the past 4 days due to the fact that I experience constant freezing in game. Video streaming results in buffering every 1-2 minutes and connection loss.

3) Is the issue intermittent, constant or does it occur at a specific time of day?

It happens throughout the day it's just sporadic. Like I may play for 10-15 minutes fine and then it becomes unplayable for while.

4) Your modem make, model & firmware version.

Motorola SB5120

5) Describe any home networking if applicable. (i.e. routers, hubs, adapters, etc.)

Linksys WRT54G wireless router. All of the issues I'm describing are being experienced over the wired connection as well as the wireless.

6) List any firewall and/or anti-virus software you have installed. Include what version you have.

Zone Alarm Security Suite ver. 7.0.337.00
