Solved Wi Fi No Hardware Installed After Replacing Wi Fi Card Macbook Pro 15 Unibody Mid 2012

Chosen Solution

My wifi has been dropping intermittently over the past few weeks (on multiple networks too) and would only re-connect after I completely restarted the device. I replaced the board but after installing the new AirPort/Bluetooth Board it still isn’t connecting and now I’m getting a “Wi-Fi: No Hardware Installed” message. I even opened up my computer again to ensure that everything was connected properly. When I did this it did connect for about 15 minutes before kicking me off the wi-fi again, thus forcing me to restart the device, to which it then said “No Hardware Installed”.

A common issue is the AirPort/Bluetooth Cable breaks down. I would replace that. Here’s the IFIXIT guide you’ll need to follow MacBook Pro 15" Unibody Mid 2012 AirPort/Bluetooth Cable Replacement and the needed part MacBook Pro 15" Unibody (Early 2011-Mid 2012) Airport/Bluetooth Cable. That should fix it!
