I have a dell laptop (inspiron 9400) with a wpi based adapter connected to a router (Linksys WRT54G f/w rev 7) over WPA. I normally have no problems with disconnections (w/ 7-stable, not 7.0-release), even with multiple long downloads using parallel connections (upto 10 per file). It works fine without any disconnections or problems until I run the Deluge bittorrent client. Once this start running, after a few minutes, all connections except Deluge stop (Deluge still runs fine). I cannot even ping the router. If I stop Deluge, other connections start working after a few minutes. Not sure if this is related, but I do have a problem when freebsd starts up. For some reason, the ip address and the route do not get setup when it boots up, although I can see the config scripts running. After I login, I neet to run /etc/netstart again before the ip address gets assigned. it gives a message 'invalid authmode' in both cases -- Gautham Ganapathy http://lisphacker.org
