Yeah, well you see, I want to be able to able to play at my school. There is a teacher who has a router for his laptop and I tried to connect to that but the DS online activity icon doesn't flash or anything, so that is why I'm asking...
well maybe he put security at the router. just ask him to put ur DS MAC address at the router, or buy wifi max, and connect it to the school computer. which i doubt they wont allow .
Go to Nintendo Wi-Fi Connection Setup (WFC compatible game required), then go to Options->System Information
