<< Solved >> BCM94360CD Big Sur Wi-Fi not working.

[denny483]

So, I am done with patching the UHD 630 iGPU and port mapping on Big Sur but now another issue popped up.
I have a PCIe BCM94360CD card in my PC with 4 antennas Wi-Fi+BT. The only issue is that the Wi-Fi does not work but the bluetooth does and the Wi-Fi is recognised in System Report.
I have looked around for solutions before writing this and I didn't really find anything useful to me as some threads I saw talked about how you had to fix your USB but that is in order for Bluetooth to work and other threads talked about using AirportBrcmFixup.kext and Lilu.kext which I put into the EFI folder but still doesn't work.
Another thing is that when I bought the card I already had Mojave installed and when I put it in it worked perfectly out of the box.
My EFI and a screenshot of System Report are attached.

i5-9600K
ROG B360G
UHD630
BCM94360CD
Big Sur 11.1
OpenCore 0.6.4

Any help would be greatly appreciated.

Did you read the bottom paragraph on the AirportBrcmFixup.kext Github page, it raised a specific issue for your card when running Big Sur.

Do you have a Broadcom BCM94360CD card working in Big Sur?

@denny483 - I notyyoir EFI contains the kexts brcmfirmwaredata.kext and Airportbrcmfixup.kext.
I was able to get Wi-Fi working natively without either of these kexts. But my Bluetooth does not work.

Check out my post here:

I'm having this issue. I also have the Broadcom BCM94360CD.

It was working fine in Catalina and both Wi-Fi and Bluetooth is working fine in Windows 10, so I'm confident it's powered, seated correctly etc.

I read your post above @Edhawk and you're correct to mention the paragraph towards the bottom of the document,

You have to block (or remove) AirPortBrcm4360_Injector.kext in BigSur.

I understand this and I have edited my config.plist as below:

<dict>
<key>Arch</key>
<string>Any</string>
<key>BundlePath</key>
<string>AirportBrcmFixup.kext</string>
<key>Comment</key>
<string></string>
<key>Enabled</key>
<true/>
<key>ExecutablePath</key>
<string>Contents/MacOS/AirportBrcmFixup</string>
<key>MaxKernel</key>
<string></string>
<key>MinKernel</key>
<string></string>
<key>PlistPath</key>
<string>Contents/Info.plist</string>
</dict>
<dict>
<key>Arch</key>
<string>Any</string>
<key>BundlePath</key>
<string>AirportBrcmFixup.kext/Contents/PlugIns/AirPortBrcm4360_Injector.kext</string>
<key>Comment</key>
<string></string>
<key>Enabled</key>
<false/>
<key>ExecutablePath</key>
<string></string>
<key>MaxKernel</key>
<string></string>
<key>MinKernel</key>
<string></string>
<key>PlistPath</key>
<string>Contents/Info.plist</string>
</dict>
<dict>
<key>Arch</key>
<string>Any</string>
<key>BundlePath</key>
<string>AirportBrcmFixup.kext/Contents/PlugIns/AirPortBrcmNIC_Injector.kext</string>
<key>Comment</key>
<string></string>
<key>Enabled</key>
<true/>
<key>ExecutablePath</key>
<string></string>
<key>MaxKernel</key>
<string></string>
<key>MinKernel</key>
<string></string>
<key>PlistPath</key>
<string>Contents/Info.plist</string>
</dict>

This did not work.

I also tried removing reference to AirPortBrcm4360_Injector.kext completely in the plist, but this didn't work either.

Finally, in the Bluetooth section of System Information it states, "No information found."

Any ideas?

Sorry for the late reply.
Got it working by deleting AirPortBrcm4360_Injector.kext.
Already tried before opening thread but only now worked.
Thank you very much for the help I received!
