Loose rivets,
Have you tried the old paperclip trick ? (i.e. factory defaults reset).
Stick Flying,
I personally prefer WPA
I'd personally put that statement a little more bluntly ....
There's no excuse for running WEP these days. It's a lousy excuse of an "encryption" protocol .... so lousy that you might as well just leave your network unencrypted.
WPA (preferably WPA2) with (for the home user without the luxury of RADIUS etc.) a good password of reasonable length is the only way to go.
Yes there are potential weaknesses in WPA/WPA2 ..... but compared to WEP it's chalk and cheese, especially if you take care to avoid a brute force dictionary attack when implementing it in it's pre-shared key form (i.e. typical home user setup) which is the most common way in for lazy script-kiddies.
