For fakeauth the aircrack-ng method doesn't works with 4965, and I think doesn't also with 5100...Cause a firmware bug, you have to use a auth with wpa_supplicant, to do this open a file and call it wpa_supplicant.conf, in it type
ssid="essid of network"
and then use aircrack suite normally..
PS: sorry for the spaces into urls but i haven't posted 15 mesg...
