If the user is still using WEP, they can have the required encryption

longer. As for those that don't have any encryption, they might as well
install a flashing neon sign saying "free wireless connections here"
A reasonably secure WPA password can be obtained from www.grc.com (Click
on Services > Perfect passwords), which is a 63 character string of
random ASCII characters. That password should be fairly difficult to
guess. That leave a brute force attack on the 256 bit WPA key.
According to what I've read, neither WPA nor the underlying AES
encryption have ever been broken.
Incidentally a 256 bit key has

possible combinations, so it'll take a while to try them all. ;-)
