[Ti] Airport Card Troubles

[Michael Ramirez]

Chris, thanks for the suggestion. I reverted back as per your  
instructions, but I'm still having the same problems. I even  
installed a fresh 10.4 on an external HD and still have the same  
problem. My guesses are that Apple may have updated the firmware on  
the card, I see this "Aug 10 22:59:42 Firestorm kernel[0]:  
AirPortFirmware: start Sta f/w download" in the System Log, my  
connection from the card to the antenna is faulty, or the card itself  
has gone bad. The search continues. Will post if I find out anything  
more.
