torrent clients causing disconnections

[MrBo]

i dont know what the issue is, but every client that i use lets me download for a couple of minutes before my connection is killed. i cant access anything on the internet until i close uTorrent, and disable/enable my connection. currently, i have:

windows firewall disabled (winXP SP2)

removed nortons 2006

there is a firewall on my modem (2Wire 2700HG-D), but i enabled port forwarding on that.

ISP is Qwest DSL.

ive read every FAQ/Guide that i could find, and have gone through them several times.. but nothing has worked. any suggestions?
