WiFi Hardware Still Not Found After Replacing Airport Card
Hello all, nice community you have here. I have a late 2012 Retina Macbook pro, 13". Model A1425, EMC 2557. Running OS 10.12.4. I fell asleep last week while using the computer and the battery died; received the "WiFi: No Hardware Installed" error message upon booting up. Tried a few software tricks, except for resetting the NVRAM, and no luck. Just replaced the card today with one I got off eBay, and to my massive disappointment I still got the message. The card was listed as fully functional.
So what now? No hardware seems damaged, and I'm pretty sure I didn't accidentally switch the antennae leads around. I'm reluctant to reset the NVRAM because I don't have a backup disk at the moment. I'd really appreciate any troubleshooting help.
Is this a good question?
