Online connectivity
The Wii console is able to connect to the Internet through its built-in 802.11b/g Wi-Fi or through a USB-to-Ethernet adapter, with both methods allowing players to access the established Nintendo Wi-Fi Connection service.Wireless encryption by WEP, WPA (TKIP/RC4) and WPA2 (CCMP/AES) are supported.AOSS support was discreetly added in firmware update 3.0.Just as for the Nintendo DS, Nintendo does not charge fees for playing via the service and the 12 digit Friend Code system controls how players connect to one another. Each Wii also has its own unique 16 digit Wii Code for use with Wii’s non-game features.This system also implements console-based software including the Wii Message Board. One can also connect to the internet with third-party devices.The service has several features for the console including the Virtual Console, WiiConnect24, Internet Channel, Forecast Channel, Everybody Votes Channel, News Channel and the Check Mii Out Channel. The console can also communicate and connect with other Wii systems through a self-generated wireless LAN, enabling local wireless multiplayer on different television sets. Battalion Wars 2 first demonstrated this feature for non-split screen multiplayer between two or more televisions.
