Every single laptop that this site owns should use backtrack 3 or 4
If you do not know backtrack is a operating system that can be booted from a live cd or usb drive
backtrack 3 can fit on a cd and a 1g usb
backtrack 4 however can only fit on a dvd and a 2g usb
backtrack is espically good for accessing wireless networks
it can crack wep in 1 minute if its inuse
wpa needs a dictionary of course but it would have to be a 10 digit list since u verse has one setup
it also can crack passwords stored on the local machine
it has many functions that i dont have the patience to state
you can get backtrack from here http://www.remote-exploit.org/backtrack_download.html
