Lets very quickly define WiFi hacking. WiFi hacking is gaining access to network via wireless means. Gaining access to a wireless access point would be the same thing as being plugged into a switch on a network. In short, we’re on the network.
But how do we get onto networks? What makes one wireless antenna better than another?
There are literally hundreds of wireless antennas that exist. If you are going to be using Aircrack-ng consult the compatibility list. The compatibility list is not complete, but use it as a gauge.
To classify what is the best WiFi adapter for hacking we need to get into a little antenna and radio frequency theory.
