I had to go wireless on my iMac - I was using ethernet cable - and I'm able to connect to the internet no problems. What is irritating me is that the wireless icon in the toolbar is empty (as if it were off) and tells me 'AirPort' not Configured. Of course, it is configured, I'm connected to the internet! What is going on?? Does anyone know of any fixes? I should add that my macbook is fine with the same updates (10.5.2).
