I have ordered two screens, both separate orders from iFixit for screen replacements for the 2012 Apple Macbook Pro 13"… each time, I replace the screen and I receive the “No Wifi Hardware Installed” icon. When I put the broken screen back on, the wifi works normally. I have reinstalled the operating systems with no luck… Any suggestions?
Agreed, makes no sense! The Clutch cover in this series only has the WiFi & Bluetooth antennas. Are you sure you have this model? As an example, this model has the AirPort board is in the clutch cover: MacBook Pro 13" Unibody Mid 2009 AirPort Card Replacement
This is weird. Are you sure you properly plugged the airport/bluetooth daughter board with the new screen? Step 5: MacBook Pro 13" Unibody Mid 2012 Display Replacement
