Instructions
Start up your Wii and one controller.
Click the “Wii” button on the home screen.
Select “Wii Settings,” and then “Internet.”
Open “Connection Settings.”
Choose an open connection slot (any open connection slot will say “None” next to it).
Click “Wireless Connection” and choose to “Search for an Access Point.”
Select “OK” when you are asked to choose an Access Point.
Choose the wireless network you want to connect to from the list. If you are attempting to connect to a secure network (signified by a lock icon), you must enter the network password.
Wait for the Wii to perform a connection test. You will receive a message letting you know the connection was successful or unsuccessful. If the connection does not work, check your wireless router. If you are connecting to a secured network, ensure that you entered the password correctly.
