Good find, well doneOk, so the problem is now fixed. After installing the updates for windows, I restarted the PC and still no jazz. It could find the networks perfectly fine, but absolutely refused to connect to them.
I eventually stumbled across the most up-to-date drivers on this webpage here: https://rog.asus.com/forum/showthread.php?124328-DRIVERS-AMD-MediaTek-WiFi-Bluetooth
And after installing these new drivers the WiFi works perfectly fine.
I don't know if this page will get cached for people searching in the future, but anyone has a RZ608 WiFi 6E 80 MHz adapter and it isn't connecting to a network, get the most recent drivers in the link above, this is version dated 28/09/2022. Alternatively, I've also seen people use CCleaner to automatically find them.
Now on to the GPU issue.
But it's not recommended to use any auto updaters for drivers as they almost always cause problems, there's no way they can know the right driver to install, as manufacturers aren't contributing to their database.
For any driver update, always go to the manufacturer website.
