Hi, I just built a PC and I have the
X670E Pro RS motherboard. I installed all the latest drivers and enabled LAN in BIOS and Ethernet is still not working. I have Windows 11 and tried checking Device Manager to configure the ethernet driver but it's not even showing. Any ideas? I doubt it's a faulty motherboard but if that's the only reason then I'll have to return it and get a new one.

I've got this problem with W11P at start when update drivers function was switched off in bios, it was resolved by switching on, but then again after waking up a system from sleep mode LAN/WiFi/BT even some USB devices are missing.
I suspect a faulty bios/AGESA implementaion or sh*tty Realtek drivers in W11.

Nothing worked. I've enabled LAN in my BIOS, reinstalled the OS, updated the latest drives via the BIOS, and nothing worked.
