Instructions
Turn off the Wii console and turn it around so you can see the back of the console. The USB ports are in the back.
Plug the Wii Lan Adapter into one of the USB connectors on the back of the console.
Connect one end of an Ethernet cable to the router and the other end of the cable to the Wii Lan Adapter. This cable allows the Wii to access the Internet through the router.
