I got a ds recently, and i have been wondering about this wi-fi thing. I know no games support it yet, but when they come out with ones that do i want to know how to work it. Do you need a wireless wouter to play with wi-fi..ir does it play from anywhere? I mean it doesnt really matter cuas i have a wireless router hooked up. But if i wanted to play with people miles and miles away from a dfferent location other then my house could I?
