5GHz WiFi on a native Apple card doesn't work properly

[ShonP40]

Hello,
I've been having 5GHz WiFi issues (2.4GHz & Bluetooth work fine) on my Hackintosh ever since I got an Apple branded BCM943602CS card, where it won't always connect to WiFi, and when it does connect, it'll have a very high ping to the router & low speeds (despite sitting about a meter from the router), AirDrop doesn't always work and SideCar just shows a black screen for a while and then displays an error.

I've tried this card on Linux (on this same PC) and it worked just fine with a proper sub 1ms ping to the router and about 800Mbps down & up (router limitation), so the issue is macOS specific.

(Its currently connected using a PCI-E adapter I got from eBay that has 3 antennas and a USB connector for Bluetooth)

Is there a way to fix this issue?

Thanks in advance,
Shon.

It's a native Apple card though, shouldn't it just work out of the box? (considering that 2.4GHz WiFi and Bluetooth work just fine)

Also I'm on OpenCore 0.8.7, latest is 0.8.8, I don't think that its going to make any differences (had these WiFi issues for about a year now)

Something is wrong here. The MAC Address isn't detected by the card.

Ah ok. As it was not cut but entirely masked, i suspected that something was off

Are you using a 5GHz Network?
