Bittorrent Woes

    I recently started downloading though BitComet and have been having trouble. I opened up the specific port in all my firewalls for BitComet and it runs great. I have no problem download or uploading at my full cable modem speeds. Here's the problem. When BitComet is running, I cannot access anything else on the internet. I have limited the upload bandwidth to 10kBps, but the problem persists. I have also limited the number of global uploads to 3. I should be way under my total bandwidth. What would be causing the freezing of my network?

    Here's my setup:

    Adelphia HSI - 4000/384 (Terayon Modem)
    WRT54GS (Thibor11 firmware - default settings)
    P4 1600MHz / 512M RAM / XP Pro running BitComet 0.61 (connected wirelessly thought a WMP54GS)

    Thanks for your help in advance!

    From what I understand, BitComet is the hardest of everything on your Internet connection. I don't know why, and I can't confirm this myself, but you may want to try another client like uTorrent or Azureus.

    I have used both of the above on a WRT54G running Tofu 10 and 12, and have not had the slightest problem.

    Of course, I don't have any experience whatsoever with attempting to run BitTorrent over wireless. I'd clamp your "total connections" down and see if that helps out.

    Your settings are too tough, by that I mean your trying to download and upload too much at once.

    Torrents are different to other P2P clients. With Kazaa if you downloaded 10 things at once your net speed was the same, the 10 things would just download a little slower each, however with torrents its different. If your trying to do to much your left iwth no upload bandwidth.

    I tried everything in these forums regarding new firmware, scripts and commands, QoS and the only thing that sorted it was this:


    I entered my true upload speed as per the speed test (195 kiloBit/second) and now my download speeds are actually better and the net is still usable by all computers.

    Dont be fooled by thinking the more you upload the faster it goes, this is only the case if your network connection can keep up, if your pushing it too far then its going to actually go backwards.

    My setup
    WRT54G v2 with Tofu 12
    2mbps NTL Cable internet with 256kbps upload (actually 195 after overhead)

    What you are saying makes since but I have capped my global upload to 10Kbps. That should be way less than the 50-55 Kbps that I can upload. I'm going to try and switch over to uTorrent or Azureus tonight and see if I have the same problems.

    When I was searching through the forums, others experienced problems with overheating. Could this a problem for me? How can you tell if your router is overheating?

    Re: Figured it out...


    While I'm glad that fix worked for you, I'm a little mystified as to how. Thibor already has that fix in his firmware, at least the Timeout values which seem to have the most impact.

    Maybe BitComet is worse than uTorrent and others about using ICMP packets and unsolicited packet usage, so the other blocks help more with BitComet.

    But, hey, your BitComet is working. That's what counts. Can't argue with success. ;)
