I've got an old Titanium Powerbook (400 mhz) running OS X that should make a good music server connected to my stereo. I'd like to add a wireless card so I can pick up Internet radio stations on iTunes (I've got a Netgear wireless router). This machine supposedly takes Type I and II PC Cards, but what's my best option? I assume a third-party card off eBay would be hard to beat, but can I use a faster "G" or do I need "B"? I've read so much about some not being recognized I thought I'd ask for help, so help, please!
