How do you use Nintendo DS WiFi?
First you must buy a Nintendo DS Wi-Fi compatible game. Turn on your DS and choose the game. Go to the games WiFi options (sometimes under settings, or WiFi Play) go to WiFi setup. Choose a slot to save the connection in, and then choose your wireless network. If you have a security system on your Wireless network, like WEP, you will need to know the password and the key. Once the connection test is successful, go back to the game, and the first time you connect to Wi-Fi it will usually tell you what your Friend Code is, or a way to find out what it is.
