So… with no Airport here, what stuff must I get?, just an Airport Extreme or Express base station to get the wifi aimed to the DS or must I add an Airport card inside my G4 MDD?, I mean, would be possible to connect the base station to the Mac via an old fashioned Ethernet cable and then the base station serving the DS as wi-fi router?, the Airport would be aimed to feed the DS, none of the three Macs over here are Airport 'ready', just sharing a non wireless router.
