I tried out an Orinoco PC Card on my PowerBook today. The card provides high-speed wireless networking at 11 Mbit/s. It worked like a charm. I'd downloaded and installed the Mac driver last night and after a couple of minutes configuring a new TCP/IP connection to use the new card this morning, I was up and running untethered. Cool!

Why they'd want to name a wireless LAN card after one of the Wombles is a mystery to me ;-)
