sub7 is for script kiddies lol......
for example.... a house near me has an encripted network. "fester"for example...... if you log onto your own router and enter "fester" into the wep-keygen... it will give ou a hexi bunch of numbers (silly people tend to use the same thing as there password also lol). there when you rescan the area and try to enter the "festor" network it will ask for the wep key.... enter thenumbers from the hexi keygen and if your lucky (or the person is dumb) you'll be given an ip address..... and even better you be able to access the net..
now when you get a ip address like .192.168.0.34 (default netgear ip range)
enter 192.168.0.1 into your address bar and you should be prompted to enter the router login user name and password..... (if ther person hsn't chnged it) its ADMIN then password.....
now ur in.... change your workgroup to WORKGROUP or MSHOME (default ms workgroups and you'll be able to see files
if there shared) once you can log onto the router you can block them! lol
not hackin' as such. just usin' ur head... sorry for the long post.....
