Playing Star Fox DS, but this has happened with Mario Kart and Digimon too, I can connect to one person for a one on one game just fine, but if I ever go more than that I get an error and it sends me back to the Wifi menu. It does that to me for Digimon and Star Fox. I forward the ports that Nintendo.com has and it's still not working, what's the deal? Now I'm annoyed. I managed to get into a 4 Player game, but right in the middle of it the game just suddenly ended. What the hell!
