There’s hardly any day or rather moment when we spend without Internet or Ethernet. Ethernet and the Internet have become a crucial part of our lives. Thinking about a life without them is simply impossible. But what if you suddenly face an issue with your Ethernet? Is your ethernet showing “Ethernet doesn’t have a valid IP configuration”? Well, in this article we will talk about all the ways you can solve this issue.

The issue windows 10 ethernet doesn’t have a valid IP configuration when your Ethernet fails to a valid IP address from the Dynamic Host Configuration Portal or DHCP. DHCP is a network protocol allowing servers to automatically assign an IP address to your device for a specific network. Hence, consequently, the computer or the device is unable to set assign an IP address. Therefore, meaning that the computer is unable to connect to the Internet and the network.

This error is caused due to a myriad of reasons. Below we have mentioned the various reasons why the error can occur. Moreover, we have also listed how you can fix this error.

When does the error occur?

So, as already mentioned, there can be a myriad of reasons why this error occurs. So, let’s check out the reasons.

  • Your Ethernet does not have an IP configuration Netgear, TP-Link

Many users have reported this problem. This problem affects any kind and type of hardware network. Hence, this is not something new or unfixable. This problem mainly persists while using Netgear devices and TP-link.

  • Ethernet does not contain a valid IP configuration powerline

Powerline is undoubtedly the easiest and the best way to set up a network. Now, many users using a Powerline have reported the ethernet error issue. Therefore, if you are using a Powerline, then check out how to fix the error.

  • It does not have a proper IP configuration router

In most instances, the ethernet error occurs because your router is not configured correctly. So, if your router is not configured correctly, then you are sure to face this problem. Hence, you have to make certain changes and adjustments to your router’s configuration to fix the issue.

  • Your Ethernet does not have a viable IP query

Now, this is simply one kind or variation of the same issue. Hence, you can solve this issue by applying the same solution. We have listed the fix below.

How to Fix Ethernet Doesn’t Have a Valid IP Configuration

Below we have mentioned how you can quickly solve the issue Windows 10 ethernet doesn’t have a valid IP configuration. So, check out the different processes and get rid of the issue.

1. Reboot the system

You should start with disabling the fast startup feature. This feature comes in Windows 10. This allows faster recovery from shut down or hibernation. Hence, this means that your computer is going to boot up quickly. So, for disabling and turning off this feature, follow the steps below:

a. Firstly, go to the search bar—type “Control Panel” in the search box. You can even press “Windows + S” and enable the search feature. Now, click on the Control Panel app to launch it.

b. Next, simply set the view mode to large or small icons for viewing all the items. Next, click on “Power Options.”

c. On the left-hand side of the windows, you will find the option “Choose what the power button does.” Then, click on it.

d. Now, click on the link “Change settings that are currently unavailable.” Note that at this point, you might have to enter an administrative password.

e. Now, simply unselect the box “Turn on fast setup (recommended). So, you will find this option under the Shutdown settings. Next, after you have unchecked the box, click on “Save Changes.” So, this will disable the fast startup feature. Hence, solving the ethernet error.

f. So, save the changes. Then, simply restart your device. After the device restarts, check whether the problem persists.

If the problem persists, then you can follow the other methods we have listed below. All the other solutions are surely going to help you.

2. Check and configure your network adapter settings

The router you are currently using automatically allocated IP addresses to each device it is connected with. This is by default. But, you can also configure the settings for assigning just one static IP address. So, you have to check whether or not this works for you to resolve the ethernet issue. So, you have to set the IP address to automatic first. Then, simply check the Internet Properties once the Internet is successfully connected.

Now, follow the instructions below:

a. Simply hold the Windows key and then press R.

b. Next, in the input field, type in “ncpa. cpl“. Then, click OK.

c. In the Network Connections window, simply right-click on the Network Adaptor. Then, click on Properties.

d. Now, select “Internet Protocol Version 4 (TCP/IPv4)” from the Ethernet Properties. Then, click on Properties.

e. Upon seeing the “Internet Protocol Version 4 (TCP/IPv4)”, enable the following options:

  • Obtain an IP Address Automatically.
  • Obtain DNS Server Address Automatically.


If an IP address automatically and the DNS server address automatically do not work for you, you must set both of them manually. So, for doing that, follow the steps below:

  1. Open the connection properties. Then, click on “Internet Protocol Version 4 (TCP/IPv4)”. Next, select Properties.
  2. Now select “Use the following DNS server addresses” and “Use the following IP addresses.” Now, check out the image below, and simply fill in the same data on your device. Once you are done entering the data, click on OK to save changes. Moreover, if you want to check the Subnet Mask or Default gateway, you can check it on any other device. You can now easily connect to the internet connection.

Note that we have mentioned Google’s DNS settings. So, if this fix did not work for you, you can check out the other solutions.

3. Restart your Modem, Router, and Computer

So, Ethernet’s most straightforward fix doesn’t have a valid IP configuration by restarting the affected hardware. So, start by saving all your work and progress, then closing them, and shut down your computer or laptop.

Next, follow the steps below:

a. In your taskbar, select the “Windows” button. Then, open the “Start” menu.

b. Click on the Power button. And then click on the Restart button. Now, this will automatically shut down the computer and again start it. You do not have to give any manual input.

c. Log in to your User account. Then, simply allow Windows 10 to back up.

Just like your laptop or computer, restart your modem or router as well.

  1. So, firstly, unplug the router or modem and keep it unplugged for few minutes. Moreover, to ensure a proper restart, wait for at least two to five minutes.
  2. Now, plug it in and wait for it to start. The LED lights on your router will indicate when it is ready to operate again.
  3. Lastly, check whether the error is resolved. Also, make sure you check the ethernet connection you are using as well. Also, try testing it by using a separate cable.

Finally, you are all set, and hopefully, the error is resolved. If still the error persists, you can scroll down and check the various other methods as well. Although this was the easiest and simplest method to fix the issue, we have mentioned some complex ones to solve the issue. So, make sure if one does not work for you, then head to another fix and try it out.

4. Update or Reinstall your Network Adapter Driver

By using the device manager, you can easily reinstall or update the network adapter driver. This is sure going to help the ethernet error. So, let’s check out the following steps:
