Wi-Fi "No Hardware Installed" even after replacing wi-fi card
So I've been fighting the wi-fi "no hardware installed" bug for sometime, on my early 2011 15" MBP. I tried replacing the drivers to no avail. Wi-fi is not available when booting to the OS X restore CD, nor at the boot drive selection screen (holding "option" at power on). I still have bluetooth connectivity.
I recently bought a replacement wi-fi card from iFixIt, and that also did not resolve the issue.
The computer is out of warranty.
I've run out of ideas. Does anyone have any advice?
Is this a good question?
