I applied the updated 10.8.5 combo updater today and still got the same wifi "not on" issue. Applying the supplemental update alone on top of that got me wifi until the next restart, but then it was gone again. Back to 10.8.4.

I have a fix!
just got off the phone with tier 2 apple tech support.
I have a mackbook 2008 and when I upgraded to 10.8.5 my wifi was completely broken.
Went through all of the typical reset PRAM, remove battery...etc.
Here is the fix:
Go to network prefs
remove the existing wifi configuration
select the - (minus sign) at the bottom left of the window.
Select Shut Down from the Apple menu.
Restart the computer.
Open Network prefs and select the + (Plus sign) at the bottom left of the window
For me, WIfi connection was populated already.
Go to the menu bar and you should now see all of your typical networks displayed.
Select your network.
Waallla! Sanity restored and your Macbook is back in action.
Have a great day!!
