Ethernet adapters missing

Windows build 19041.867
Gigabyte motherboard.

At least I think they are. If I go to Change adapter settings I see my Wifi adapter and 2 ethernet adapters (one for Wifi), but they are both Hyper-V Virtual adapters.

Hyper-V is not enabled. I enabled it, restarted, checked - no change, disable it, restarted. No change.

It is possible that my MB has failed, it is giving me problems. New one is on order. Just worried that it is a Windows setting which is causing this.

Diagnosing shows no problems.

BTW, my router confirms that ethernet is not working and networking in the notification area also doesn't mention ethernet, just Wifi. I can't stream my movies without it.

This is confusing because adapter can be either WI-FI or ethernet, but not 2 ethernet one of which is WI-FI.

Please follow steps below to share system information file:

1. Click on Windows button
2. Type msinfo32 on your keyboard
3. Right click on "System Information" and Run as Administrator
4. If asked for password enter your password and click OK
5. Click on: File -> Save...
6. Save the file to C:\ root drive
8. Zip up this file and attach to your reply

You either connect computer with LAN cable to router or use WI-FI, having both connections is place is not as simple so you have to make your choice.

You indeed have physical ethernet adapter installed but to figure out why it's not present do this:

1. Right click on Windows button and select "Windows PowerShell (Admin)"
2. If prompted for password, enter administrator password and click "Yes" to continue
3. Copy all of the code below at once, right click into console to paste and press enter.

Code:

Get-NetAdapter -IncludeHidden -Physical | select * > $env:SystemDrive\adapter.txt

In your C:\ root drive should appear adapter.txt file, please attach it to your new reply.

Thank you, unfortunately the command failed to capture realtek ethernet adapter, and msinfo32 shows the driver is not running so very likely either motherboard or adapter itself has gone bad or there is problem with the driver

If you remember this adapter was working fine recently it could be because of Windows, you can try out installing another driver, gigabyte site does not offer any new one (most recent is from 2015) (both chipset and LAN driver), instead try get chipset driver from with INF utility:
Download Chipset INF Utility

If installing chipset does not work in Windows go to:
System -> Update & Security -> View optional updates -> Driver updates
Try to find "Intel - System" or similar and install it then reboot system.

For LAN adapter see realtek site below:
Network Interface Controllers > 10/100M Fast Ethernet > PCI Express Software - REALTEK

Install realtek driver and see if this works.

You're welcome, new MB is good, current one is already old enough.
