If you just want to temporarily share then I think "access point" is unimportant - can't you use "ad hoc" mode? "Access point" means getting a wifi card which supports master mode. Not all do. I question whether this is worth the bother - routers are just too cheap. If you want to do something complicated, which is not available in the menus of your $20 wifi router, then run OpenWRT Linux on a $40 router. The extra cost of a recent router will quickly pay for itself in electricity savings, over leaving your big desktop PC on when you only want to surf the net on your netbook. Stroller.
