have you tried updating to 7-stable?

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
