I say cut out the airport and just use a wireless router. Do you have a desktop PC that you can have the wireless router plugged into full time? I have the Linksys broadband router and love it. My computer is plugged in with an ethernet cable (4 ports on the back) and hubby uses his laptop wirelessly. Everything that I have read says that it is combatible with the MAC OS but that it may be slightly trickier to set up. I personally think Linksys is the best brand of wireless router out there. I'm not sure which models allow mac but if you search for linksys wireless routers you will find it.
