So I just updated my Aluminum Powerbook 15 to 10.4.4 via software update, and system prefs now tells me that "No Airport Hardware is Found" when I try to connect to the Airport base station I've been using for the last 2 years. Incredibly annoying. System Profiler still reports that I do, in fact, *have* airport, but OSX doesn't recognize it. Anyone heard of this? Any suggestions?? Thanks.
