Hello all,


I just updated to Mojave and I'm having some wifi troubles. Currently, my wifi is stuck on "looking for networks" or will just say "wifi on" and won’t display any of the available networks. I have installed the IO8211Family kext but still nothing...


My wifi card is the TP-Link 4800. It worked fine with High Sierra but obviously isn't working now with Mojave.

  • Using Kext Utility or KextBeast or Terminal commands , install AirPortAtheros40.kext in /S/L/E and reboot the current Mojave with TP-link 4800 and check System Preferences_Network to see your WiFI is Enabled.
  • Copy and paste the same kext in CLOVER/kexts/Other of your System Disk's EFI/EFI/CLOVER/kexts/Other ( May not be necessary , but I did it anyway)
  • If you have trouble getting that kext, you can unzip and use the AirportAtheros40.kext.zip I have uploaded.

I started with editing the 8011 kext and installing to S:L/E, now I just used kextbeast and A40kext in L/E and it works well and withstands updates. For me Kextbeast L/E is all it takes.
I normally keep everything in Clover and have Inject Kexts rather then detect and it still works.

I too extracted it from the IO80211Family.kext>plugins folder in macOS High Sierra . I keep a copy in my Installer's CLOVER/kexts/Other for my use and to help anyone struggling with non-working TP-LINK TL-WDN4800 Dual Band Wireless N900 PCI Express Adapter in Mojave installation.

Unfortunately it didn’t seem to work. I’m beginning to think my card could be dead? Super confused about it all now...

  • If your card is dead , you won't be able to use in Windows or Linux to access any WiFI network.
  • From your initial post or current response, readers have no way of knowing for sure you have confirmed that your TPLink Wdn 4800 PCIE WiFi card is not working in other OSes like Windows and Linux before concluding that the card is "dead".
  • Device Manager in Windows, lshw -C network command in Linux, and DPCIManger in Hackintosh can tell us the status of our WiFi card.
 
If you added the 8011 kext to System/L/Extensions folder and didn’t clear caches it may have become inactive. Try opening up S/L/Extensions folder and search out Atheros40kext, and 8011 Kexts and remove them. Rhen rebuild caches and then use Kext beast to reinstall the 8011 kext (original) to S/L/E and then run kextbeast again with the Atheros40kext using L/E option. Then reboot. Remember that kextbeast will load every kext you place on the desktop so only have one present at each loading.

In my case, Kext Utility will automatically repair permission and rebuild cache on dragging the target kext on to the launched and password permitted Kext Utility interface.

Once that is successfully done, once again with a Password entry on prompt, you can quit KU.

Once you reboot the system, Wifi adapter will show up in System Preferences>Network and all that is needed is to find your Network through Network name list of any broadcasting Wifi network to pick your Home network by the name you have given when you had set it up.

Unfortuenalty this also didn’t work. My WiFi icon is just grey with no signal bars and no networks show up…
