If your interested in buying a WiFi usb, your only option is the Officiall Nintendo one. It looks as if it would work since it kinda looks like the Nintendo usb adapter, but you shouldn't buy it if you havent done research about. The Wii allows only certain adapters to work. I bought two different ones before i got the Nintendo usb, and neither worked just the Nintendo did. So you should really google around and ask someone whos had it. Sorry i cant be much of a help but i never tryed the product so my answers very limited.
