Please read me:
Ever since macOS Mojave came out (I mean the first DP) Apple removed the support for Atheros based WiFi Adapters from the IO80211Family.kext, so to fix it we need to add the AirPortAtheros40.kext to the Extensions manually.
After each clean install the AirPortAtheros40.kext needs to be installed and after clean installing Mojave DPs after few times I decides to create this app to save some time.
How to use it:
This application will install the missing AirPortAtheros40.kext into /System/Library/Extensions and after the installation is done and once you reboot your computer the Atheros based WiFi adapters will be enabled.
The installation is the first step of the process and it is fast but the next steps which are repairing the permission on /System/Library/Extensions and rebuilding the system caches might take a while so please wait until you were asked to reboot your computer.
I'm using a TP-Link WDN4800 with an Atheros chipset and it works on other similar hardware.
If this app helped you please consider donating; any amount is appreciated.
