I am on the latest verson of Mountain Lion (10.8.2) and when I turned on my macbook pro I get an issue on where the wifi says "no hardware installed". I know there is because I was using it but 10mins beforehand. I reset the PRAM and everything but it still does not work. Is there anything else I could do or will I have to take it into the Apple store (or someplace like CompUSA?) in order for them to fix it

    Also since then the computer has been running very sluggish (2.26ghz core 2 duo and 8gb ram)

    All kinds of weird fixes for this issue have been reported, most of which make no sense. I think it's usually or always caused by a hardware fault, which may be intermittent — something like a loose connector or a failed solder joint. Almost anything might seem to fix it, at least temporarily. In some cases, a software or firmware bug may be involved.

    The Apple Hardware Test doesn't find anything, as usual.

    To rule out everything but a bug or a hardware fault, take each of these steps that you haven't already taken:

    1. Make sure all available updates are installed.

    2. Reset the NVRAM.

    3. Reset the System Management Controller.

    4. Boot into Recovery by holding down the key combination command-R at the startup chime. In the OS X Utilities screen, select Get Help Online. A copy of Safari will launch. Test, then reboot as usual.
