Things You'll Need
Instructions
On your computer, log in to your router's "Internet Settings."
Under the Internet Settings, look for a "Wireless" or "Wireless Security" setting.
Look for the WEP Key field. Many routers have settings for four WEP keys. The Wii will only work with the WEP Key in the first position.
Carefully write down the WEP Key. It will be a long, alphanumeric string.
On the Wii main menu, click on the Wii button on the bottom left of the screen to access the Wii Settings. Then click "Internet" and "Connection Settings." Look for "WEP" to input and save your WEP key on the Wii.
