Is there a way to reinstall the airport software without reinstalling OS X? I have a flat panel iMac that runs 10.4. One day after a thunderstorm and power outage the Airport stopped working. The wireless network works fine with my other macs. I bought another airport card (128bit) online and installed it. In the system profiler it says under airport card it says "no information found" however when I run the hardware test that came with OS X.4 it identified the card and serial number and passed the test. this sounds like an airport card recognition software issue but I do not want to reinstall my entire OS and loose my pics and music any advice or thoughts before I reformat the whole computer?
