‘Ethernet does not have a valid IP configuration’: Easy Fix 2021

Ethernet does not have a valid IP configuration

‘Ethernet does not have a valid IP configuration’: has this error message been constantly popping up on your screen? This is a common problem faced by many Windows users as their device is unable to get proper IP address from the DHCP server, such as the wireless router, modem, or switch. You have nothing to worry because there are a few rather simple solutions to the problem. Read on to know more!

What causes the ‘Ethernet does not have a valid IP configuration’ error?

An Internet Protocol (IP) address lets devices communicate with one another over the internet through the IP-based network. This IP address is like the identity of the device on its network. It is similar to a unique business location that has a particular address, which can easily be recognized by others. There are all kinds of IP addresses, like dynamic, static, public, and private. 

If you get the error message ‘Ethernet does not have a valid IP configuration,’ it indicates that the Windows operating system is not getting the valid IP address from the Dynamic Host Configuration Protocol (DHCP). Now, what is DHCP? DHCP refers to the network protocol system that is responsible for letting the server spontaneously assign the IP address to your device for a particular network.

So, when you getting that error message on your screen, it means that your computer has not been assigned the IP address. Thus, it is not being able to establish a network connection, and you’re unable to get an internet connection. The error is typically brought upon by incorrect, outdated, or faulty network adapter drivers, or issues with network configuration.

Six solutions for the ‘Ethernet does not have a valid IP configuration’ error

Give below are the six easy ways for you to solve the ‘Ethernet does not have a valid IP configuration’ error.

1. Restart the router or modem

At times, a simple restart can be enough to solve this issue. So, the first thing that you need to do is save all the work that you have done, and then, shut down the computer. Unplug the modem or router and leave it like that for a few minutes.

Plug the modem or router back after a while, and give it some time to start. After it starts, it’s time to turn on your computer and check if the error is still showing. Also, check that you are using an Ethernet cable, and try using another cable to test the connection.

2. Disable the ‘Fast Startup’ option

The ‘Fast Startup’ is the feature that is added by default in the Windows 10 computers. It is put there to ensure faster recovery from shut down or hibernation, so that your device boots up faster. Follow the steps given below for disabling this feature:

  • Press Windows + S to search and open the Control panel
  • Change the ‘View’ option to Large or Small Icons and search for Power

  • Click and select what the power buttons are to do on the left side of the screen

  • Choose Change settings which are presently unavailable
  • Under Shutdown settings, uncheck the ‘Turn on Fast Startup’ option to disable the feature
  • Choose to save the changes and restart the computer

Check to see if the issue persists even after you’re turned the feature off. Move on to the next solution if the error is still showing up.

3. Change network adapter settings

An IP address gets designates by default by the router, although the settings can be changed to have a particular IP address. Here are the steps to accomplish that:

  • Open the Run dialog box by pressing Windows + R. Type ‘ncpa.cpl’ and press enter.
run
  • Select Properties by right clicking on Ethernet adapter settings

  • Search for Internet Protocol Version 4(TCP / IPv4) in the Properties dialog box, and click on it to get the Properties of the Internet Protocol Version 4(TCP / IPv4). Here, you will have to enable two options:
  • Automatically obtain the IP address
  • Automatically obtain the DNS server address

You will have to manually set the DNS and IP address if the automatic method does not solve the problem. Given below are the steps to do it manually. After you’re done with the previous steps and reached the Properties of Internet Protocol Version 4(TCP / IPv4), edit the given options:

  • Fill in the sections you find on your screen with these digits.
  • 192.168.1.15 (IP address)
  • 255.255.255.0 (Subnet mask)
  • 192.168.1.1 (Default gateway)
  • Go to the DNS server addresses, and fill in the details given below:
  • 8.8.8.8 (Preferred DNS Server)
  • 8.8.4.4 (Alternate DNS Server)

These are the DNS settings of Google. Click ok, and see if the issue is fixed or not.

4. Deleting network cache

Sometimes all you need is to reset all the contents of DNS client resolver cache and fix the DHCP configurations. Here are the steps to delete network cache:

  • Press Windows + S to search and open the Control panel. 
  • Open ‘Elevated Command Prompt’ by clicking on the option ‘Run as Administrator.’ You can also get the option to run as Administrator by right clicking on the command prompt.
  • Click ‘OK’ when you are asked for permission
  • Enter the given commands in the ‘Elevated Command Prompt’ box
Ethernet does not have a valid IP configuration
  • ipconfig / release
  • ipconfig / flushdns
  • ipconfig / renew
  • After entering these commands, restart your computer to check if the issue has been resolved.

5. Reinstalling network adapter driver

Use the Device Manager option in the computer for updating or reinstalling the network adapter, and see if this solves the problem:

  • Press Windows + S to search and open the Device Manager. You can also open the Run dialog box using Windows + R, enter ‘hdwwiz.cpl’ and hit enter for opening the Device Manager
  • Once the Device Manager opens, you will get a list of devices that are currently connected to the computer. Search for the Network Adapter option, and expand it. Now, choose the option ‘Uninstall device’ by right clicking on the device.
  • Select ‘Uninstall’ on the confirmation box, after marking the option ‘Delete the driver software for this device’

Restart the computer to see if the error shows up anymore or not. If the uninstalled drivers are not automatically installed by Windows, open the Device Manager once more. Choose ‘scan for hardware changes’ by right clicking on your computer’s name. Install the missing drivers after they are detected.

6. Change the TCP/IP settings

You will have to use a netsh command and the command prompt for trying this fix. It lets you modify or display the network configurations of your computer. Given below are the steps to change the TCP/IP settings:

  • Press Windows + S to search and open the Control panel
  • Open ‘Elevated Command Prompt’ by clicking on the option ‘Run as Administrator.’ You can also get the option to run as Administrator by right clicking on the command prompt.
  • Click ‘OK’ when you are asked for permission
  • Enter the given commands in the ‘Elevated Command Prompt’ box
Ethernet does not have a valid IP configuration
  • Netsh Winsock reset
  • Netsh int IP reset

After running the first command, you’ll be shown a message that asks you to restart your computer. You can ignore this prompt for now, and go ahead with the second command. Restart your computer after you have run both the commands.
