Also, if you do have Animal Crossing: Wild World, go and check the map and go towards the main gate. Enter to the main gate, and you should see booker and copper. Copper is the one on the right. Press the third option "friend code!" and copper should explain everything. Also, make sure when you go to the very first screen, press the fourth option "other things." and then press the next fourth option "wi-fi settings." and then you should be able to see if your DS can connect to the internet. If not, then you can always find a place like Mcdonalds that always has free wi-fi.
