As of the first release of macOS Mojave, Apple has removed the support for Atheros based WiFi adapters by removing the AirPortAtheros40.kext file from the IO80211Family.kext/Contents/Plugins so if you have been using one of those cards you need to add the missing AirPortAtheros40.kext back to /System/Library/Extensions or /Library/Extensions to make your WiFi adapter active again.



The process is so simple:

There is a simple way to add the missing kext file back to macOS Mojave which is to download the AirPortAtheros40 installer from our download section and easily install the missing KEXT file back to macOS with only few clicks and by using the installer you don't need to worry about the permission repair and rebuilding the system caches because it will be done by the installer.


After rebooting the computer your WiFi will be active.
