Last night, I tried updating to Big Sur. I tried with Clover r5127, OpenCore 0.6.3, and OpenCore 0.6.2. I encountered the same issue with all three that I don't know how fix... Everything worked except Wi-Fi. The Wi-Fi is not even seen as PCI device at all.

Here's the Wi-Fi card in Catalina:

It's completely missing in Big Sur:

Reboot in to Catalina and the Wi-Fi works perfectly again... I'm at a complete loss...

make sure to use that list instead of what you have, as the ordering is import with OpenCore

also remove:
debug=0x100
for quicker booting :)

I don't think it's the way the kext is being injected. The wi-fi isn't even seen as a PCI-e device.

Also, it doesn't work with Clover r5127 where we don't have to tell the config.plist how to load the kext. All three EFIs that I tried has working wi-fi in Catalina...

your kext is missing the plugin folder, try the one attached

Big Sur works differently, scroll to the bottom of the page:

Holy smokes! That did it! Thanks!!

I needed to update AirportBrcmFixup... :banghead:
 
Feartech said:
yup! :)

assume you have it working now? :)

Yes! Thanks!

My biggest mistake was assuming that even with a non-functional kext, the device would show up in the PCI list...
