How to Use Wii USB Ports

When Nintendo first began selling the Wii in 2006, there was much excitement over the USB ports in the back of the device, but the excitement soon faded when people realized that these ports were not able to do as much as they thought. Future updates to the Wii operating system might allow users to better use these ports, but you can also use them for LAN adapters to connect to the Internet.
Make sure that you have an Ethernet cable that is connected directly to your modem or wired router. The Ethernet cord should be long enough to reach the location of your Wii game console.
Turn off the power to the Wii game console. It may be best to completely unplug the power supply from the back of the Wii. Insert the LAN adapter all the way into the USB port that is on the back of the Wii console.
Find the Ethernet outlet on the Wii game console. Take the Ethernet cord that is connected to your modem and connect it to the outlet in the Wii. Push the Ethernet cord in until you hear it click into place.
Plug the power supply back into the Wii console and turn it back on. When the Wii menu appears on screen, click on the "Wii" logo on the bottom left-hand side of the screen.
Click on "Wii Settings" to change the settings that will allow the Wii console to communicate correctly with the Wii LAN adapter that is hooked into the USB port.
Click on the blue arrow when the next screen appears, to move the screen to the right. Then select "Internet." Finish the setup process by selecting "Connection Settings," then "None," then "Wired Connection" and "OK."
Use only LAN adapters made by Nintendo. Other types likely will not work.
Do not try to connect to the Internet with a dial-up connection. Doing so will likely be fruitless, as the Wii was designed to work with broadband connections.
