I have a PowerMac G4 with a first generation Airport card running OS X 10.4.3 and a Nintendo DS with a copy of Mario Kart DS. My computer gets broadband through an ADSL modem and until now I have never used the Airport card for anything. I want to get Mario online so I went into the Sharing preference pane, turned on Personal Web Sharing and Internet sharing but the DS cannot find anything. How can I tell that my Airport card is working? How do I get the DS to pick join the wireless network and go online? I am very disappointed by this game. It was supposed to be very easy to get online but it looks like once again Mac users have been left out of the equation. Worse of all there is no help on the internet because everyone is too busy playing the game. The other threads on this Forum have not been very helpful, including the one from Zeeman that many people have pointed to. If anyone knows how to get the DS online please tell me how.
