No WIFI hardware installed

[sigomez]

Hi Everyone,

Hope someone can help me out with the issue I am currently encountering with my early 2013 Macbook Pro Retina. I was having wi-fi issues with the latest update of Yosemite (10.10.2) and read online about reverting back to a previous IO80211Family.kext file. I tried this but like an idiot i deleted the previous one on there.

Now I am running into the issue where the one I installed isn't working and my computer is saying there is no wifi hardware installed.

I tried rebooting in recovery mode and of course wi-fi is there; I also tried resetting the PRAM and the SMC but neither of those worked. Any help is greatly apprecited.

Thanks in advance.

Sergio

Perhaps someone can provide you with the 10.10.2 kext file.

Try posting over in the Yosemite forum.
