    When I use Bittorrent (Tranmission or Deluge), it works great for the first 10-15 megs, maxing out my speed, then it hits a wall and drops the download speed to 10% of what's capable... besides that, it slows my overall internet experience even if i close down the bittorrent client...

    if i turn off my wireless connection, then turn it back on through the network manager, my internet is back to normal speeds as long as I don't use bittorrent... start downloading a torrent files then the same thing happens...

    I've setup my port correctly in the client, i've opened them up in FireStarter, and I've used the following code to make sure everything is fine..

    sudo iptables -A INPUT -p tcp --dport 6881 -j ACCEPT

    anyone have ideas why my internet slows down so much after laucnhing bittorrent?

    it's not that it's a seeding issue, because like i said before, even after i close my client down the internet is slow till i disable & enable my wireless..

    Here is an example of what i mean...

    Fresh boot, cleared cache + history

    Restarted computer

    Opened transmission, got to about 20 megs out of a 375 meg torrent file, then my internet speed dropped, quit transmission.

    Opened firefox, cleared cache + history
    [​IMG]

    go to network manager, disable wireless, then immediately enable it again and my speeds are back to normal...

    other points of interest...
    I use Transmission on my mac, so i've put in the exact same settings...
    router is a WRT54GL running Tomato firmware
    Ubuntu is the only OS that causes this, downloading the same torrent on Windows or OSX maxes my speed till the very end without issue

    Comcast doesn't like BitTorrent. They're clamping down on your connection so you don't actually use all the bandwidth you paid for, because what they sold you was a connection that was only intended to provide the advertised bandwidth for short bursts.

    Alternately, maybe you just have a shitty network card in your Ubuntu machine.

    maybe you should work tech support, you're super helpful and seem knowledgeable...

    according to deusexaethera, it's probably comcast screwing you over just on that system... not all your other systems, just the ubuntu one...

    Well, if it's only happening on one system, and that system is running Linux, then it's either a driver/ndiswrapper issue, or the NIC is overheating and slowing down. You're the Ubuntu-hacking badass, you figure it out.

    i have one computer dual booting win7 and ubuntu right now, it only happens on the ubuntu partition, so i suppose it could be a driver issue. definitely not my ISP or the NIC itself though :dunno:

    why not try completely encrypting your traffic and trying again?

    Okay I narrowed down my issue to the built in Network Manager being a piece of shit... I replaced it by installing Wicd (http://wicd.sourceforge.net/) and redoing my internet connection...

    no more bittorrent issues, i can download and upload max speed...

    based on my previous statement...suck it...:fawk:

    known issues with most other *unix distos and cheap ass NICs... if you run a Intel card, Broadcom, etc, then no problems..

    most mobos have the crappy Realtek chips on them which have terrible support
