Being released on September 18th in Japan for 5,800 yen (US $53) is the Nintendo WiFi Network Adapter for the Nintendo Wii and DS. This wireless LAN router can also be used with PCs and other devices as well as Nintendo Wii and DS, it can also be set to “Auto” which automatically switches over the household network. It also has 2 other modes on the back “Router” and “Bridge”.
Router mode is what it says and is self explanatory and bridge connects to another router and then communicates with the Wii and DS.
No word on a U.S. release as of yet, but I think it will be right around the corner.
