Now you will be at a screen with a blue square and a orange rectangle click the blue square that says Nintendo wifi connection setting (this screen will be the same for any wifi game). Now click connection 1. Now search for an access point. It will search for connections. It should find yours. Click it and then it will test the connection. then go back and it should say connection 1 Ready. There should should be all set. Oh and there should be a booklet in the game case that should be able to help you if any problems occur.
