How do I protect my computer against shit like wifikill and other

Thanks for telling me about wifikill, I can finally weed out my family for watching netflix on 4 different computers all day hogging the bandwidth.

What about connecting via ethernet?
Chances are that works by ARP spoofing. So on your PC figure out how to make a static entry in the ARP cache.
Or find out who's doing it and beat the shit out of him, which is easier, faster and gets the point across
