<< Solved >> Broadcom BCM4331 BCM94331CD No Wi-Fi or bluetooth

[MrMotley]

I've got an old Broadcom BCM4331 BCM94331CD installed for bluetooth and wi-fi. They worked in Sierra with clover and since I've from scratch gone to Monterey using OpenCore neither bluetooth or wi-fi are working, they're just not showing up as an option. Obviously I've not set something up correctly via OpenCore but am not sure what, I assumed I didn't need any drivers.

I did find this mention saying "BCM94331CD (may need to force the kext to load for Catalina)" but I don't know what kext to specify to force.

Would this be where I need to mess around with the USB port mapping?

Hi MrMotley,
BCM4331 chipset is only supported up to Catalina. This chipset is not going to work in Monterey.

Thanks, guess I'm off to look for a new wireless card.
