The Wii has Wi-Fi built into the system which allows users to connect their console to the Internet when they have a wireless router or Nintendo Wi-Fi USB Connector available. The Wii LAN Adaptor is an accessory that allows users to hook up their Wii console to the Internet without the need for a wireless network. The adaptor connects the Wii console via one of its USB ports to a wired access point, such as a broadband modem or wired router.
