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

[ShonP40]

Already did that, didn't help.

The issue is macOS connecting to the 5GHz network but getting extremely low speeds & high ping times + AirDrop sometimes doesn't work at all or just transfers files very slowly (as its using 5GHz)

Enable ExtendBTFeatureFlags and then check.

Bluetooth & Handoff are working just fine.
Its just every feature that requires 5GHz WiFi is lagging (this includes 5GHz WiFi itself and AirDrop)
I can connect a Bluetooth gamepad & my AirPods with no issues

Try a different Router/Network.

Already did.
And as I stated before, this WiFi card works perfectly fine on Linux, only macOS is having these issues.

Try a clean install.

I already tried that when upgrading from Monterey to Ventura.
Did a full clean install in hopes that this issue would disappear.

Try experimenting with Wireless channels.

Did that already.
And its still not explaining how this card works completely fine when I boot my PC into Ubuntu but not on macOS, even though its an official Apple card

Try adding brcmfx-country=#a in boot args.
