Then it's only a matter of time before they can see one of the clients on the network log off, and use their IP address.
Even if you use a MAC address filter, I can sniff the clients in the air and get their MAC and use a De-auth attack to kick them off the router, then spoof your MAC to one of the clients.
WPA2 with a strong password non dictionary password. making your AP so unattractive they will go and freeload somewhere else. because if they want in they will get in.
Unless, the person happen to be a neighbor living near that signal, and nothing else is close enough to connect to.
In which case, time is what you would have
But my main point that I'm trying to get across is EVERYTHING is crackable eventually, given enough time and resources.
and I believe that the secret worldwide ACTA treaty that will enforce anti-piracy to the fullest extent, is very dangerous, because they can't just say, that everybody in the whole house must loose their internet connection, because they happened receive a notice about copyrighted material coming from that IP.
it's just madness (not to mention almost impossible), to make ISP's into net nannies.
But I think the ISP's will go for it because it would give them the right to start getting involved in "Behavioral advertising" while they are already getting involved with users traffic.
