The Wii is designed to be Internet-ready right out of the box; it comes with an internal wireless card and supports most configurations of home wireless network. To connect your Wii to the Internet you need to go to the Wii settings menu and configure the wireless settings.
To connect the Wii to the Internet you will need a broadband Internet connection in your home connected to a wireless router; dial-up users will not be able to create a home wireless network.
Generally, the Wii will work with any modern router that you may have in your home. Nintendo Support does not offer a list of supported or problematic routers, but they do have a compiled list of thirty-one different brands of routers and how to find the settings necessary for connecting your Wii to your wireless network (see "Resources").
The Wii supports the 802.11 broadcast standard, either B, G, or mixed frequency. On the whole, most routers work in one of these two frequencies; you can check the box before purchasing to ensure that it supports 802.11B/G or go to your router's administration settings to double-check. Routers that work in 802.11N may not work with the Wii wireless system.
The Wii supports all forms of home wireless encryption, including WPA, WPA2 and WEP; whichever method you use is entirely to your discretion, depending on how secure you want your Internet connection. WPA2 is considered the most secure of the settings if you have a strong password to accompany it. You can also connect to insecure wireless networks if your home network does not have encryption enabled.
