Don't worry. WPA2 is standard.

Simply don't.
My guess in the dark: you have manual on the CD. Try to get defaults.
Then enable or disable what you like or dislike. Try to change channel
to 1, 6 or 11. Maybe it has option for aes, which is what you want. Try
to be close to ap. I've read that some ap's are not fully wpa2 ready.
If you live in civilized area, try to replace it for wrt54gl. There is
even newer version, that has nas included.
