I've got a MacPro with DSL wired directly. My wife got a Macbook for Christmas (she was good this year), and so I want to set up a small, simple wireless network for our place. I'm completely ignorant of wireless networking, so here come the questions: 1) Can I install an Airport card in my MacPro and share our DSL connection that way? Also, can I share my USB printer that way? 2) If option 1 isn't a no go, what kind of device can I plug into my second ethernet port to share the DSL? I'm confused by the different things like access point, router, etc. I've currently got Internet Sharing and printer sharing working via my second ethernet port (works great), but I'd love to lose the wire. Thanks!
