Hi all, I just recently purchased a friend's 12" PowerBook G4 (1 GHz ). I reformatted it using my store bought Tiger DVD. Since then, it has not recognized the AirPort Extreme card. I took it out (it's in the battery compartment) and put it back - not a loose connection. I ran all the software updates and restarted. The System Profiler has "No information found" under the AirPort Card heading. I don't know what else to do. I'm completely stumped and I can't find any support articles to troubleshoot this problem. Thanks in advance.
