after owning my pismo powerbook for almost two years, i just got an airport card (about $53. "open box") and a netgear mr814 router ($50, plus a $20 rebate, buy.com)
plugged everything in, ran the airport setup utility with 10.2.4...and i'm in!
great how all this works, how everything configures itself.
the netgear is a great buy.
and i'm writing this from the balcony, with a great view of lower manhattan.
brilliant!
