Hi,
I have TL-WN722N USB adapter with AR9271 driver and when I want to let it be in monitor mode by "airmon-ng start wlan1" and then use wash to see which networks around are WPS locekd by "wash -i wlan1mon" it retrives something like "ERROR: Could not filter packets". It's getting a bit more weired when I type "airmon-ng stop wlan1mon" - "...device is not in monitor mode" while I can see it should be when typed airmon-ng.
Does somebody know whats wrong with that?
Thanks a lot.
Note I did not kill NetworkManager process.
