Reset My Router. WEP Key?

Hey everyone.

Last week, I reset my router to change my IP address (lol ban evasion). But now, I have either reset my WEP key or have none, so I can't access the internet from my DS, Wii, or PS3. I've looked into my router settings, and I can't seem to find it anywhere (Unless i'm overlooking something). What should I do?

First, think to yourself.

Do you really NEED Wi-Fi to enjoy all your games.

If yes
