To hack a wi-fi password, you will need:

You can go online and buy a wireless card with RTL8187L chip easily.
  3. Boot your computer from the Linux distro. For our purpose, we will suppose that we use Backtrack4 to crack wireless password. Type startx to get into the Backtrack4 graphic user interface. On the bottom of the screen, you will need an icon named Terminal. Click on that, then you can use the set of commands that you will find on the Aircrack-ng to hack a wifi password. For example, you can use airmon-ng wlan0 to check whether your wireless card is supported by Aircrack. You can change your mac address by typing in macchanger, etc.
