This is a video tutorial on the very basics for cracking a WEP key. There are several tutorials online but after following them and playing with them, I found out why they never worked for me. I like to continue running the command “aireplay-ng -1 1 -a xx:xx:xx:xx:xx -h xx:xx:xx:xx:xx wlan0″ I find by keeping a steady authentication with the access point it allows me to get packets and by using them with the command “aireplay-ng -5 -b xx:xx:xx:xx:xx -h xx:xx:xx:xx:xx wlan0″. Each time the command is run and it reads packets it will ask you if you would like to use it. Just keep saying yes. Keep making sure you do this, especially if the access points are further away. By doing this you will get less errors while running the commenand “aireplay0ng -1 1 -a xx:xx:xx:xx:xx -h xx:xx:xx:xx:xx wlan0″ This will cause traffice and you will notice that if you look at your window from running “aireplay0ng -3 -b xx:xx:xx:xx:xx – xx:xx:xx:xx:xx wlan0″ the ARP Replies will start increasing giving you proper #Data from your Airodump. If you notice that you are over 10000 in your #Data but after running aircrack-ng you are still not able to obtain the key, there can be several possibilities. If the network is set to a 64-Bit encryption then it will take a lot faster to crack, meaning if you have about 15000 for data, it should work. 128-Bit networks can usually be cracked with about 30000 Data. You can wait until the #Data reaches 30000 if you like and open 2 more consoles and have …
