If you would like to see 802.11 frames generated by the ethernet wireless adapter(wlan0). Execute the following command.


iw dev wlan0 interface add mon0 type monitor

ifconfig mon0 up


# create adapter
iw dev wlan0 interface add mon0 type station

#

# change into monitor mode

ifconfig mon0 down

iwconfig mon0 mode monitor

ifconfig mon0 up




You can see a virtually created monitor mode adapter named mon0.
