How to resolve: Ethernet does not have a valid IP configuration

Your computer uses an Internet Protocol (IP) address to connect to the Internet. This is the address that identifies the device on the network. It is used to communicate with other devices or with the Internet.

If you are getting the error message “Ethernet does not have a valid IP configuration“, it is because your Ethernet connection is not getting a valid IP address from DHCP (Dynamic Host Configuration Protocol).

This is a network protocol that allows servers to automatically assign your computer an IP address for a specific network. As a result, the computer cannot be assigned a valid IP address, which means that it cannot connect to the network and the Internet.

This error can be caused by a variety of reasons, from faulty network adapter drivers to improper network configuration. In this guide, we will present you with several solutions that will help you solve the “Ethernet has no valid IP configuration” error.

How to troubleshoot the Ethernet does not have a valid IP configuration

Reinstall the network adapter

  1. While holding down the Windows key, press R.
  2. Type hdwwiz.CPL in the input box and click OK.
  3. Expand Network Adapters, right-click the Ethernet card, and select Remove Device.
  4. When a confirmation dialog box appears, click Uninstall.
  5. Reinstall the network adapter using the driver that came with the hardware.
  6. If reinstalling the Ethernet card does not fix the problem, you must reinstall the network card with the latest driver from the manufacturer’s portal.

Reboot the router and check the Ethernet cable

  1. Turn off the router or modem and turn it back on after five minutes.
  2. Now check if your PC has a valid IP configuration.
  3. If that still doesn’t work, connect the router to your PC with another Ethernet cable.
  4. If not, you may need a different router.
  5. If connecting to another router does not solve the problem, then the problem is with your network card.
  6. Perform a factory reset of the network card and, if that doesn’t help, replace it.

Use the command line

If you can’t access the Internet because of the “Ethernet has no valid IP configuration” error message, you can solve the problem by using the command line.

According to users, you can easily solve this problem by running a few commands. To do this, follow these steps:

  1. Press the Windows + X key and select Command Prompt (Admin) from the menu.
  2. If the command line is not available, you can use PowerShell (Admin) instead.
  3. When the command prompt opens, type the following commands:
  • netsh winsock reset
  • netsh int IP reset

After running these commands, just reboot the computer for the changes to take effect. After restarting your computer, the problem should be solved and you should be able to access the Internet without any problems.

Restart your system

  1. Press the Windows + S keys and go to Control Panel. Now select Control Panel from the list of results.
  2. In the Control Panel, select Power Options.
  3. In the left pane, click Select Power Button Actions.
  4. Select Change settings that are not currently available.
  5. Uncheck Enable Fast Startup (recommended) at the bottom of the window to disable Fast Startup.
  6. Select Save changes.
  7. Reboot your computer.

Check your network adapter settings

The router works to automatically detect the IP address. This is the default setting, but you can also assign a specific IP address.

In this case, you need to set the automatic IP address first, and once connected, check that the settings are correct in the Internet properties. Follow the instructions below:

  1. While holding down the Windows key, press R.
  2. Enter ncpa.CPL in the input box and click OK.
  3. Right-click the network adapter in the Network Connections window and select Properties.
  4. In the Ethernet Properties window, select Internet Protocol version 4 (TCP/IPv4) and click Properties.
  5. The Internet Protocol Version 4 (TCP/IPv4) Properties window then opens. Enable the following options:
  • Obtain an IP address automatically
  • Obtain a DNS server address automatically

If obtaining the IP address and DNS automatically does not solve the problem, consider setting the IP address and DNS manually. To do this, follow these steps:

  1. Open the connection properties, select Internet Protocol version 4 (TCP/IPv4), and click Properties.
  2. Now select Use the following IP address and Use the following DNS server addresses.
  3. Fill in the details as shown in the screenshot below. When you are finished, click OK to save your changes.
  4. To see the necessary information, such as the default gateway and subnet mask, you can simply check the connection properties of any other device that might successfully connect to your network.
