In case 2 (with default chan 1), ifconfig wlan0 gives error "SIOCSIFFLAGS: Input/output error" # iw dev wlan0 set channel 1 no output generated, also nothing in dmesg # iw dev wlan0 scan trigger command failed: Network is down (-100) nothing in dmesg. Both commands do not give any output in dmesg in case 3 either. Tried channel 1 up to 11, 12 and higher gives 'command failed: Invalid argument (-22)', which is expected I think. > One more thing to try is create a monitor interface and run kismet on > it.
