Thread: Wireless Issues After Upgrading to 12.04 (Atheros AR9285)

tried searching forums didn't see solution particular problem threads similar ones, , tried asking irc told create thread.

anyway, upgraded 11.10 12.04 , can't connect wireless, working smoothly before same settings. asks me wep key, attempts connect , gives in , asks key again. i've triple checked key , tried resetting router, no luck. tried inputting same key wpa/wpa-2 in case written on router in error (it states "wep(64bit)") again, no joy. stated in title, chipset atheros ar9285.

outputs are:
