I use Ubuntu (Feisty Fawn), and I'm having a little trouble with the wireless. It works fairly well in gnome when configured using network-manager, but it's kind of hit-or-miss. Also, if I log out of gnome and use a different window manager (xmonad), eventually the wireless craps out, and it takes a lot of dicking around with network-manager to get it to work again. I'm able to verify at the time that the wireless is working from a roommate's machine.

Is there a better replacement program, maybe console-based, that will allow for easy configuration and reestablishment of my wireless? dhclient? Something like that. I'm a programmer, not an OS guy :-X

I just don't trust network-manager, it feels brittle as hell.

Suggestions?
