  1. Make sure you have created the directory /etc/reaver; otherwise things won't work.

    Run sudo airmon-ng start <INTERFACE>.

    Check that iwconfig shows the new interface (usually mon0) as being in Monitor mode. Managed will not work.

    Run aircheck-ng and turn off any processes it tells you might be bad. Afterwards, use airmon-ng stop mon0 and then airmon-ng start wlan0 to recreate the (hopefully) monitoring interface.

  2. Had the same problem, and after a few hours I realized that I'm not running reaver as root (run with sudo)

  3. mon0 is not a terribly likely name for a wireless interface. I know it's the one in their screenshot, that doesn't mean it's right for your system.

    Try ifconfig to see what yours is called.

    Incidentally, mine runs with wlan0 BUT wants to be told my own mac address with -m switch, & doesn't like mon0 at all.

  4. try ifconfigselect the wireless network start with w as like wlan and command the following sudo airmon-ng start wlan to set interface as monitor mode be sure mon0 will enabled to monitor mode and capture the packet of mon0 by using this command sudo airodump-ng mon0 and finally start the sudo reaver -i mon0 -b bssid -a -N -vv -c 1
