I am in Jaunty with the same Inspiron / Intel hardware, same Tomato router (Version 1.25 in a Buffalo WHR-HP-G54).
It will work fine for hours, maybe even days, and then suddenly disconnect and refuse to reconnect. Logging out and logging in doesn't help, turning off wi-fi in hardware doesn't work.
nm-applet repeatedly tries to reconnect and nothing happens. The only thing I can figure out is to reboot.
(Oh wait, this is an older bug.) The symptoms are the same and it's on the same hardware, so I guess I'll keep it.
Since upgrading to Jaunty the problem has reappeared. Several other users experience the same thing:
