I dont believe that will work. The Wii has a Wireless adaptor built in. If you have a wireless router already then you dont need anything else. If you are looking to connect your wired network to your wii you will have to use the nintendo wired adaptor (I believe you plug eathernet from your network into the adaptor and it connects through the USB in the back of the Wii) or use the Nintendo wireless adaptor that sends the signal to the Wii. The adaptor you have here recieves signal to a computer.
