No wifi after catalina

[phoenixAL]

there is a IO8021family.kext from high Sierra that has a airport.....40.kext in it

With sip set to allow unsigned kexts etc I placed that airport kext into the plugins folder of IO80211Family.kext that’s part of Catalina in /S/L/E it’s not a hackintosh kext it just from older OS
the Older Io80211 kext I found on herethere a reason Apple dropped support for that hardware
I never had airdrop that I know of
The fenvi t919 card has it plus Bluetooth

in the US average wifi card that works with macOS about $30 or more, Bluetooth adapter $15-$20 let’s say $50 for both I paid $55 for the fenvi t919 and about $12 in tax and faster shipping

it works out of the box with macOS
Windows I had to plug in network cable so it could download drivers for both WiFi and Bluetooth

Thanks for the suggestions, I'll look into it

had same issue with my wdn4800. quite simple fix for me, by placing atheros40.kext and IO80211Family.kext into /EFI/CLOVER/kexts/other

I just copied the IO80211Family and it works. Thanks
