    Default "Wi-Fi: No hardware installed"

    My MacPro wouldn't wake up this morning. Rebooted it, and then had no internet. In the menu bar I now see the wi-fi icon with an X through it and a message, "Wi-Fi: No hardware installed." Huh? When I went to bed last night I had wi-fi. Did a little gremlin thief come and steal my wi-fi hardware in the middle of the night?

    Try resetting the PRAM:

    Restart and hold: cmd-opt-p-r until you hear a 2d startup chime. Thereafter release the keys and let the computer start up normally.

    PRAM = Parameter RAM. Which is where the system stores configurations. Things like startup disk, speaker settings, monitor resolutions and so on.
