So i've had my old DS for 5 years but i've never bothered to pick up a wireless router. But now that i have a DSi and 1000 free points to start off with (get me 2 or 3 games for that much) i really want to get online, so i went to the Maccas gotspot and it came up on the dsi but it wouldn't link with it. What's up with that?

Any help? Otherwise i gotta stand outside my ex-friends house because he's the only person i know that can link his DS to wi-fi...
