my friend told my of a hack program which will hack the WEB key and WPA key, this program is called cain and able and only works on windows, Warning its very complicated and you will need to be a nerd to configure it out so look for the tutorial on youtube or something:
by the way some anti viruses will think that cain is a virus but oxid has said they do not distribute viruses, worms, Trojans ext.
P.S i have a way to unblock web filters like school filters its called vtunnel and heres the ip address to the site incase the normal address is blocked http://184.108.40.206/
and here is some more that i pinged myself
