Hi, I've upgraded from Mojave to Catalina and now my WiFi card didn't recognized in system. I upgraded clover and kexts to latest versions, but Wifi didn't appears.
In "about this Mac" I see:
CoreWLAN: 13.0 ((null))
CoreWLANKit: 13.0 ((null))
Menu Extra: 13.0 ((null))
System Information: 12.0 (1355)
IO80211 Family: 12.0 (1200.12.2b1
Diagnostics: 1.0 (910)
AirPort Utility: Not Installed
My kexts is:
I checked forum and table of supported Wifi cards - and everything should work (a lot of people has this card working on Catalina). When I was on Mojave my wifi was ok.
As I can see in terminal output ( after command "kextstat") - kext for wifi not loaded, but I'm not sure because I haven't got a lot of experience of this
*my english isn't good enough, sorry for that*
m.2 DW1707/AR9565 shows yellow wifi indicator in network applet when turned on in 10.13.6, 10.14.6 and yellow ethernet in 10.15.2.
Icon in desktop panel indicates looking but not find networks in all three. Same wifi card detects available networks in linux without issue.
The attached kext is labeled particularly for 10.13.6, but wifi is not being detected even in that version. In all cases Atheros 40 kext is installed S/L/E as plugin in 80211 family kext with reparied permissions.
Can anyone who has this working in sierra, high sierra, mojave or catalina please post what you did including any dsdt/config.plist mods?
From what I have read in these forums the modded atheros 40 kext is supposed to work. Is this failure to detect networks specific to any particular brand(s) of laptops?
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.
I will be using ASUS ROG STRIX B360-I GAMING (mini-ITX) for my new build, and I'm trying to figure out the best solution for WiFi & Bluetooth. I understand that it should be possible to replace the WiFi/BT card that comes with the motherboard, but I'm confused about with what kind of card exactly. What connector will I need to be using? There are cards with miniPCI, M.2, some solutions require adapters, ...
