This is all a different language to me, but yes have WEP, I don't remember passphrase I just bumbled through somehow when initially bought it and plugged it in and hey presto the original laptop connected (it lists 4 keys) I thought I'd just enter the key that was bullet point selected into the new laptop somewhere

Clicked add new station (if thats correct) what the hells a MAC address?!

Actually I don't think I did create a passphrase, I would've remembered, I just dunno how I got the laptop online! I can't find anywhere on the new one to add the keys/security details to
