I'm trying to get a cross-platform wireless home network up and running. Of course, I'd really prefer not to purchase seperate routers for my mac and pc. If anyone can answer them, my questions are these: 1)Will an Apple airport base station work with any network card, including ones for PCs, or only Airport cards? 2) The corollary: Will PC-based access points(like the ones from Linksys, etc.) work with a Mac? 3) Will a wireless pcmcia card typically work in either machine? If so, does it depend on whether it's an Airport or PC-based access point? 4) The new Airport comes in two flavors: one is $50 more, and comes with an antenna and modem. Don't all wireless routers need antennae? And would the version with the modem eliminate the need for a seperate cable/dsl modem? Hope somebody can enlighten me.
