Well, if you have a Nintendo DS, then getting access to Nintendo's Wi-Fi Connection isn't hard at all. All you need to have is a Nintendo DS, a game capable of Wi-Fi connectivity (any game with a Nintendo Wi-Fi Compatability sticker on it, such as Metroid Prime Hunters), and a wireless internet connection or Nintendo Wi-Fi USB Connector.

Then, when you start up your game and go to multiplayer or Nintendo Wi-Fi, you'll be asked to configure your settings (or can select a menu to go to such settings). There you can manually configure your connection or simply go to the settings and select to search for an access point for immediate configuration.

If you've got more problems or need more help connecting, visiting www.nintendo.com or www.nintendowifi.com may provide you with help, especially under the Customer Service section.
