No 5 GHz WiFi on BCM94350ZAE (DW1820A)

Hello folks,

I'm using BCM94350ZAE (DW1820A) for my Build (Check it out here)

It works like a charm with AirportBrcmFixup kext.

Only thing I'm missing is 5 GHz WiFi.

They aren't shown in the available WiFis and yes I have 5 GHz AC Networks available.

Can anyone help?

Thanks in advance!
