Cracking WEP Keys

Looks like you neglected to mention how you get past routers that are using mac address filtering. To bypass ones with those, make sure to change your mac address to that of the router itself. The router itself will not block itself, therefore, mac address filtering is shit.

I should also note that a copy of backtrack is completely, and overly, unnecessary. And to be honest, I've had issues with it recognizing my wireless devices. I prefer to just use a simple Ubuntu with Gnome and just install aircrack-ng and macchanger.

sudo su

Fill in the appropriate password for super user.

apt-get install aircrack-ng apt-get install macchanger

Alternatively

sudo apt-get install aircrack-ng sudo apt-get install macchanger
