My Macbook Air was bought October 2012 but has this WiFi/BT card. It failed and the machine would not boot, even to recovery or single-user mode, and removing the card allowed it to boot.
Awesome instructions. Followed step by step and didn’t screw up my Air. Thanks for your assistance!
Is possible to replace this with a newer card? Be nice to have wifi-6 and Bluetooth 5.2
Just followed these instructions and they worked! Typing this from my now stable WiFi
