High Sierra does not detect my PCI combo card

Hi,

It seems that High Sierra doesn't detect my combo BCM943602CS card. In my system report, under the PCI tab, nothing is detected (https://imgur.com/a/Sej4N).

Obviously, no wifi on the network system preferences. But the bluetooth does work (probably because it's wired to the USB pins on the motherboard).

Tried to use DPCI Manager, nothing detected.

Tried to switch to the other PCI-E slot, did nothing.

I am using a Gigabyte H270 Gaming 3 motherboard. Maybe the issue comes from it ? I also searched anything related to PCI in the BIOS but did not find anything noticeable...

Any help is greatly appreciated since I made everything works on my config except this.
