    I just updated my 2008 Unibody MacBook 13" from 10.8.2 to 10.8.3 and have the same problem. When I restart the computer the WIFI symbol in the status bar shows that the wifi is OFF if I try to turn it ON it looks like it turned ON but won't detect any wifi network.

     

    I tried accessing to System Preferences > Network > Diagnostics > Wifi and it detects that the wifi is OFF even when I had already turned it ON before in the Status bar. It then tries to re-Turn it ON and won't detect any network or do anything else.

     

    Any suggestions? I'm downloading in my other Mac the 10.8.3 combo update to try to reinstall it just in case there is a orphaned file that didn't update correctly with the normal update.

     

    Any suggestions are appreciated! I'll update after the update.

    I just reinstalled 10.8.3 Combo Update and the wifi still won't turn ON. Bluetooth works and ethernet also works without problem.

     

    any suggestions are appreciated. Thanks in advance.

    Finally found the solution in another Thread:

     

    All You have to do is:

     

    1. Go to your Macintosh HD drive in Finder (system drive)

    2. Go to Library/Preferences

    3. Drag the 'SystemConfiguration' Folder onto the Desktop (creates a BU copy - just in case)

    4. Delete the 'System Configuration' Folder within the 'Library Folder' (empty the Trash Bin - just in case)

    5. Reboot - This recreates the network files (automatically)

    6. That's it!

     

    My wifi is now back and Works now like a charm.

     

    Hopes this helps to solve your problems.

    This worked the first time, but when I powered it down and back up again it started doing the same thing. I tried the same process twice to make the wifi turn on and find my network, but no dice. Any suggestions? Thank you.

    I've been tyring this, and it did work at the beginning, but now after a few days it's not working anymore. Anyone with other ideas?

     

    Which was the other thread you found this in Npalamidis?    Thanks, Jeremy

    It would be nice to get an Apple Support Specialist to address this issue in this discussion. I'm dealing with the issue, and many others are. It's only fair that we get a direct solution to the problem from Apple.

    @Marcus, yes, I wish the same, but these forums are not the place where Apple Inc folks come to sove problems. It's mostly user-to-user discussion and problemsolving here. We have to submit reports to apple here:

     

    http://www.apple.com/feedback/

     

    Have you upgraded to Mavericks? I haven't had any more wifi issues since upgrading. Might be something to consider.

    Yeah, I called Apple and found a solution. Basically, the network patterns in the computer somehow undid themselves. So the solution was:

    • Shut Down

    • While rebooting, hold down Command + Option + R until globe appears

     

    This will perform a network recovery. Once you're in the utilities screen, you can can click on the Safari option and should be able to browse in this window. Once done, restart the machine. If you're like me, the machine will still not allow Wi-Fi to be turned on. So the end solution is to open system preferences > Network > Wi-Fi. Under location tab, add a location (name it whatever you'd like), and delete the Automatic location option. This should solve the problem, and connect you instantly.

     

    Automatic is just a default location. Adding a new one should refresh things and get them up and running.  This was the course of action Apple Care took with me. Hope it helps!
