WPA or WEP For PS3?

So yeah, which security is better for ps3?
i heard WPA is safer, but can be too strong sometimes, so it stops the key info exchange from happening. I have WPA atm and that quite often happens.

Plus, if i wanted to change to WEP, how would i do that? I go to my router page, select WEP and then it comes up with 4 boxes named WEP key 1-4. i dont think i even have a key? haha :P

So yeah, your views?

Put a WEP key in the first box. It must be 10 hexadecimal characters long for 64-bit encryption or 26 characters for 128-bit.

Maybe use the same key as your WPA one for ease. It can be anything as long as the characters are A-F 0-9 and is the correct length.

will it really make any difference to me using WEP?

I use WPA2 and it works fine PS3 connects it's self everytime and doesn't lagg or time out or anything.

WPA is a more complex encryption I think, so you'd probably benefit on security and speed.
