i have an mn-730 wireless card that works fine under windows, and it has worked before under knoppix (i'm running from a 3.6 hd-install, with ndiswrapper ver 1.1). however, it has stopped working, and i don't know what went wrong. apparently it can get a signal and it sees the access point, but i cannot get an IP for the life of me. even if i try to set one manually, i can't ping the router. any ideas?
