Verify that you have the two items needed to connect your DS: a WiFi compatible DS game and a wireless router with WEP or less encryption. Sometimes the DS has trouble with more advanced router security. Insert a WiFi compatible game into the Nintendo DS and access the wireless network options screen. Each game does this a little differently so check your manual if you have trouble finding it. Use the options interface to set up a new wireless connection. Choose "Nintendo WiFi Connection Settings," then your first unused connection preset, then "Search for a Wireless Access Point." If everything is set up properly you should be able to find one and connect. Look at the color of the padlock next to your connection name. Blue means you are ready to go, red means you need to supply a password to connect (common with most home routers) and gray means your router is using security that the DS doesn't understand.
