Technique filtering through the MAC ADDRESS

sometimes we find that it gives a chance AP mac address only some can go ... The following are examples of such restrictions through the technique .. yes bypass technique again ..

for example I use backtrack SO 4:

# Kismet

(option)

space
S - to sort
S - to sort the SSID
Down Arrow - Put in AP SSID that you want.
ENTER - detail AP
C - see who the client AP

Make sure airmon inactive in WLAN wlan0 (for atheros: ath0)

# Airmon-ng stop wlan0

To change the MAC address of the WLAN on eth1 to be equal to the MAC address is allowed AP client

# Ifconfig wlan0 down
# Ifconfig wlan0 hw ether 00:16: CF: C1: FA: F5
# Ifconfig wlan0 up

or to random MAC address

# Macchanger-r wlan0
