Hi I'm new here (occasional mac user) and I have problem I'm hoping someone can help me with. I borrowed a friend's ibook G4. She assures me that she has used it to connect to wireless internet in the past (with out external hardware). I lifted the keyboard and I see a sticker with an AirPort ID number - so it certainly seems like the card is there. System profiler (under AirPort) says: "No information found". System preferences -> Network says: "AirPort is currently Off", "AirPort Power: Off", "Network: not available", "Base station ID: Not available", "Status: No AirPort hardware found". The pie slice that should be in the task bar is not there. I had a quick look through the archives (but didn't see anything conclusive). Any help would be much appreciated.
