Oh, come on, it took me cca 20 minutes to go from being an absolute noob to
being able to crack my own network. It requires reading through one web page
and four man pages.

Set source MAC address.
Read the output of airodump-ng for a MAC address of an already connected
client to find one that is allowed by the access point firewall. How much of an
expert one needs to be to use an option switch in a command?
Really, people typically have no idea how easy it is to crack a wireless until
they actually try it, at least once. After that, one gets to appreciate what
is really a security measure, and what is the "please don't open me" sign on
the door.
MAC spoofing is trivial. Even in Windows there is a field to type a desired MAC
somewhere in the network settings...
Best, :-)
