Ethernet Doesn’t Have A Valid IP Configuration’ Notification in Windows 8.1

Try Disconnecting the Ethernet Cable and positioning in a different Router or Switch Port.
This may release the IP Config and Renew.
Two Connections may have been assigned the same ipconfig if dual boot options exist on the same PC by the DHCP Server.

  1. Log on to the Windows 8/Windows 8.1 computer with the administrator account.
  2. From the Start screen, click the Desktop tile.
  3. On the desktop window, press Windows + R keys simultaneously on the keyboard in order to open the Run command box.

  4. In the available field in the Run command box, type NCPA.CPL command and press Enter.
  5. On the opened Network Connections window, right-click the icon of the network interface card that is connected to the network and is facing issues.
  6. From the context menu that appears, click Disable.
  7. Wait till the NIC gets disabled, and once it does, right-click the icon again, and click Enable this time.

  8. Wait till it successfully receives an IP address from the DHCP server.
  9. If the issue persists, press Windows + X keys simultaneously on the keyboard. (Windows 8.1)

  • 10. From the displayed menu, click Command Prompt (Admin).

    Note: In Windows 8, go to the Charms bar > Search, type CMD in the field, right-click the Command Prompt from the list, and then click Run as administrator from the context menu.
    11. On the displayed User Account Control confirmation box, click Yes to provide your consent to continue.
    12. On the opened Administrator: Command Prompt window, type the IPCONFIG /RELEASE command and press Enter.

    13. Once the command is executed successfully, and the cursor starts blinking, type the IPCONFIG /RENEW command and hit Enter.

    14. If the problem still persists, check if the LAN cables are properly connected and they are not broken from anywhere (in case of wired network).
    15. If everything is working fine at your end, you can check the DHCP server in case it is available within the local area network, or you can try contacting your ISP if the DHCP server is present at its end.
