Wi-fi: No hardware installed - Is it possibly an SSD issue?
I have a 2012 11" Macbook Air and the airport icon on the menubar is greyed out with an X and says Wi-Fi: No hardware installed. I have tried a lot of fixes. SMC reset, PRAM reset, booting from USB drive loaded with OS X, re-intalling OS, Deleting the network, and more.
This problem started with the most recent update of Mavericks. So it seems unlikely to be a hardware issue. However, I just remembered there is a SSD recall on the 2012 Macbook Airs and noticed that the Apple support page warns users not to upgrade the OS. Does this seem like a possible candidate for diagnosis?
If it was as easy a fix as walking into an Apple store to fulfill the recall it would have been done by now but there are none for thousands of miles.
