Hello.

I have a problem with my Ethernet adapter on the X870E NOVA and am at a loss:

The error already occurred during the initial installation: No network card was found. After a few attempts, it suddenly worked and I thought it was just a problem with the setup.

But the problem is much more subtle:

The network card worked fine at first - for hours.

But as soon as the computer goes to sleep and is woken up again, the network card has disappeared. Even in the device manager. Sometimes even when I shut down the computer.

Only when the computer is shut down and disconnected from the power supply for at least one minute does the network card reappear and then work again. Depending on the powersave settings in the BIOS, I also have to unplug the network connector to get the Ethernet working again.
The problem occurs on both my 1G switch and my 2.5G switch.

Bios, Windows and drivers are up to date. I have also tried various power saving settings in the BIOS without success.

Help!
