Windows 10 – Fix Ethernet Adapter Disappeared

ethernetfirewallnetworkingrouterwindows 10

My Windows10 PC has no ethernet network connection since yesterday. The port is part of the ASUS X570 motherboard. In 'View Hardware and Connection Properties':

  • Ethernet: Status is Not Present, Connectivity is Disconnected.
  • vEthernet Status is Operational and Connectivity is Disconnected.

Ethernet adapter isn't present in Device Manager.

Steps:

  • Reset router/modem
  • Tried different ethernet ports on the router
  • Changed the ethernet cable
  • Network Troubleshooter comes up with no results.
  • Tried reinitializing all network states as suggested below.
  • Windows Network Reset
  • LAN Controller in BIOS is on
  • Delete vEthernet Adapter in Device Manager
  • Green ethernet port LED is on when cable is plugged in, orange LED is flashing
  • Reinstall drivers

The same router is connecting successfully to an RPi4 via ethernet, and wifi works for my MacOS laptop and Android phone.

I'm wondering if this is a firewall or network setup issue. If so, what are steps I could take to troubleshoot? I had previously messed around quite a bit with my ports and firewall settings.

Try completely reinitialising all network states.

Run the following commands in an elevated (run as Adminstrator) cmd shell:

  • Reset WINSOCK entries to installation defaults (reboot required):

    netsh winsock reset catalog

  • Reset TCP/IP stack to installation defaults:

    netsh int ip reset reset.log

  • Reset Firewall to installation defaults:

    netsh advfirewall reset

  • Flush DNS resolver cache:

    ipconfig /flushdns

  • Renew DNS client registration and refresh DHCP leases:

    ipconfig /registerdns

  • Flush routing table (reboot required):

    route /f
