    I have a MacBook 5.1 (Late 2008 model) running on Mountain Lion. Yesterday when I opened it and I can't connect to the internet and I checked the WiFi connection and it said "No Hardware Installed", I tried to turn on the WiFi in the System preferences and it won't work! What should I do?

    A few things to try:

    1. Reboot and Zap PRAM twice
    2. Shutdown and remove battery (can't remember off hand if the battery is removable on that model) and unplug and hold power button for 20 seconds.
    3. Repair Disk Permissions
    4. Reinstall OS, or at least create a bootable USB to see if it has the issue as well.

    Or the card could have just died, in which you would have to repair it or go with and external usb option.

    I have the same model and had this problem after I upgraded to 8.5, I found that it happened occasionally to me only if I put it to sleep whilst on the mains.

    Powering down and rebooting it running off the battery seemed to fix it.
