"As long as you have a wireless router that is compatible with the Nintendo WFC -- and almost all of them are -- then you will be able to connect to the Nintendo WFC from your home. For gamers who do not have a compatible wireless router, and do not wish to purchase one, Nintendo offers the Nintendo Wi-Fi Connection USB Connector as an alternative. Unfortunately, this device is not compatible with Macintosh systems. You can still play by connecting at a local Hotspot, or purchasing a compatible wireless router."
