Maybe your driver needs to be patched.
After updating to ~amd64 aircrack-ng, it's working like this: # airmon-ng start wlan0 # airodump-ng wlan0 Injection is also reported to work. The only problem is I don't get any results from airodump-ng unless net.wlan0 is started. 'ifconfig wlan0 up' doesn't seem to help. Can I monitor without associating net.wlan0? - Grant
