Broadband Internet service: Cable connection Lagging?

    Hi I’m new to the forum and I have a connection problem. I’m using comcast high speed cable and when my son plays x-box live, he always gets booted beacause his connection “lags” we have played games with other people who have DSL and they have problems with us lagging also. Any ideas on why I’m having this problem? I’ve tried to just connect the x box directly to the cable modem, power cyling the modem, but I still seem to have a “slower” connection than anyone else who games online. The other thing is that when I used to play computer games online, I used to lag badly also. Any help would be appreciated!!

    If you are experiencing lag with multiple devices and when directly connected to the cable modem, you’ve pretty much narrowed it down to a problem with Comcast’s network in your neighborhood. I would call them and tell them about the problem; if you can give them lag times, that would be even better, because it will give them an idea of how serious the problem is. They probably have no contractual obligation to improve the situation, and in any case they won’t do anything quickly, but it can’t hurt to complain. If you’re seeing delays of over 200-300ms, they really should take action, and good broadband service would really keep your ping under 100ms.

    In case you’re wondering, there’s nothing about DSL or cable modem service that makes one or the other better for lag times… but if your Comcast service continues to be subpar, you might as well try out DSL to see if the service in your area is at least up to par.

    Thanks for that info chase!! I’ve been browsing getting knowledge on the subject.

    Here’s a couple of speed tests I’ve done

    http://www.dslreports.com/linequality/nil/2158377
    line quality test.

    I’m paying for the 6meg service and as you can see sometimes i get more than 6meg download. The tech that came out stated this also and said that everything was ok. but sometimes I drop all the way to 1000kb/s and of course it will never happen when they come out to check. I’ve had 2 tech’s come out and look at it so I’m kinda wondering what my next step should be, and what could I do on my side to show/prove to them that I am having a problem?

    I’m glad you found DSLreports. They probably have the greatest wealth of information on the topic of fine-tuning your connection. I noticed in your line quality test that 12.116.160.6 appears to be a bottleneck; I tried to do a reverse DNS lookup on this address, but couldn’t find any useful information. If you test again at a later time and you get the same results, I’d try to investigate this address (or ask Comcast to do so).

    The speeds you’re seeing are really incredible, but your ping is still a little slow (although I’m surprised that they’re slow enough to get you kicked off of Xbox Live). I might also try the DoctorPing tool to compare yourself with other users on your local Comcast system. If you’re not up to snuff, try searching around the forums there for tips on cutting down your latency.

    Chase, I have finally figured out the problem. I called comcast today and complained again, told them about the latency and irratic speeds. They checked everything on their side and initially said there wasn’t a problem. I started explaining that about packet loss and the rep did a couple of pings. The first 2 came back normal but the 3rd on had 100% packet loss. FINALLY someone was able to see it happen. SO he advised me that the modem needs to be replaced so on monday, I’ll get another modem and we’ll see how it goes. Thanks again for all your help, and I’ll post the results on monday. Hopefully this thread helps anyone else who might be having the same problems.
