About This File

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.

doesn't work on catalina final, sip is disabled.

Also putting the kext is L/E and rebuilding cache returns:

 

Kext rejected due to improper filesystem permissions: <OSKext 0x7fde40d0b620 [0x7fff8e2d9b00]> { URL = "file:///Library/Extensions/AirPortAtheros40.kext/", ID = "com.apple.driver.AirPort.Atheros40" }

 

Finally solved. Extract IO80211Family kext from this installer and use hackintool to install it.

This is what worked for me in Catalina final-

- Disable SIP from recovery

- Get Hackintool

- Unlock it (Bottom left corner)

- In Tools tab, run Disable Gatekeeper (Home icon on the bottom)

- Run the installer by Cyberdevs

Add it to your clover/kext/other/ directory, My WDN4800 worked without any issue.

IO80211Family.kext.zip

Yeah it works, it wasn't working before I have been testing this since Mojave's release so I made the installer; but now using the clover/kexts/other works on both Mojave and Catalina. I guess the new revisions of clover made this possible which wasn't working before.

You need to disable SIP in recovery mode, boot into macOS and run the installer and once you're done you need to reboot back into recovery and then you need to rebuild caches and prelinkedkernel and then boot back into macOS OR use the steps that @haunteddevil619 suggested.

@Cyberdevs Adding it to opencore kext directory is also working.

The setup worked really well. Thank you.

I got AR9285 working on Catalina. There is a small problem: the signal strength shows 1 dot at the bottom only. The laptop is less than a meeter away from the router and it looks odd. Any ideas?

Hi, as far as I know the signal strength shouldn't be affected at all, the only thing that comes to mind is to make sure the antennas are connected correctly.

It worked perfectly on Atheros AR9280, Catalina 10.15.2.

Got some errors when using the app v2, so instead "open" it and copied the kexts from inside to Clover v.5100 "other" folder, and restarted. That´s all.

Thanks a lot for making those kexts!

Hi,

 

It works well on Catalina 10.15.3.

But, I don't know why, I have a sleep issue with the Kext and don't have without.

I can go to sleep but I have a black screen until I wake up.

If someone knows what to do, it will be appreciated. ;)
