You usually need to be plugged directly into the router and type in its IP address into an explorer window, usually 192.168.0.1 or 192.168.1.1, then type in the username and password, this is brand specific if you have never entered a password. Then navigate to the security menu and enable WEP, I also recommend hiding the SSID. You really need a manual before you start this, there are a lot of little differences between brands. I've set up 20 or so wireless routers and most brands are really easy one you get used to the interface. PM me if you need any help.
