I have the same card. On Big Sur you have to disable one kext in order for WiFi to work.
First, you only need 4 kexts. No need for FakePCIID.kext:
AirportBrcmFixup.kext
BrcmBluetoothInjector.kext
BrcmFirmwareData.kext
BrcmPatchRAM3.kext

Now disable this entry in your config.plist under Kernel-Add.
Read the bottom section about it here:

Questions.

Can you set the min kernel max kernel to only disable it for Big Sur? If so can the same EFI boot Mojave, Catalina etc.??

I have not tried that myself, but, according to the github info, it should work. I simply disabled the kext from loading in my system. What is the use case for this I wonder? I would not use the same EFI for Mojave, Catalina or other version simply because SIP settings are different for each OS.

SIP does not need to be disabled for most systems. CSR Active config can normally be set to 0x0000 once the system is configured. Disabling it is usually done to set up a system or hardware device. Once configured you should be able to set It back to 0000 for a secure system.

For laptops it’s most likely not an issue because of limited drive bay options. But in a situation where you want to mount an external drive of a different MacOS Version or from another PC it could be useful.

@Lucca.Fernandes Do not post multiple questions about the same issue.

I have answered this question in two of your other posts, there are no kexts or drivers available for your BCM43227 WIFI (not Wife!) card.

Posted in another thread but will post here as it is more specific to this one. Latest OC 0.7.0 broke by native BCM94360NG card. It is off and would not turn on.

Did you Clear or Reset NVRAM when you upgraded to OC 0.7.0?

Does the Bluetooth side work on the BCM94360NG card?

I assume you can't use the On/Off button in the System Preferences > Networking pane to turn the device on.

Have you tried deleting the WiFi device from the Networking preference pane, using the minus (-) icon at the base of the Networking Device list. Then rebooting the system and seeing if the WiFi device reappears in the Networking pane with the WiFi switched on?

NVRAM was cleared several times. Removed the WiFi card from the Networking list and rebooted. Cleated NVRAM again. Card is not listed anymore in the Network section of System Properties. Manually adding the WIFI card does not help either. Bluetooth continues to work though.

Have not tried any kexts as card was working OOB before. Reverted to OC 0.6.9, cleared NVRAM but still the same issue. That means it is not the OC that is to blame. Something else is going on...
