From memory you can either do it manually or automatically. All the easier automatic route entails is switching on your WIRELESS router and have the Wii search for it and save the settings. With the manual way, you will need your SSID name and WEP/WPA password. Insert these into the various boxes, let the Wii search and again save your settings. Please note that the Wii works with wireless routers out of the box. A wired connection will need a LAN adaptor.
