I hear ya. The Wii and DS already have Wi-Fi. True, but this device is a Wi-Fi router/bridge for those who don’t have wireless networks. Even when you do have a wireless network, it can be a pain to get your Wii set up depending on your provider. The device will be available in Japan on September 18th for $53.
Obviously it resembles one of those Wii knockoff jobs from China, but it’s the real deal. The adapter has a switch for three modes on back: “Router”, “Bridge” and “Auto”. “Router” is self-explanatory, while “Bridge” connects to another router and then communicates with the Nintendo DS and Wii. “Auto” will switch the household’s network over automatically.
