We are going to explain what it means and how to solve the error “Ethernet doesn’t have a valid ip configuration” that your computer may give you on occasion. This is an error that can sometimes appear from one day to the next, and we will try to make you understand what exactly is happening by explaining the error to you, and then we will give you several methods to return to normality.
We are going to give you several ways to solve it because the error can have different origins. We will do this for you, we are going to propose several different solutions. From experience we know that the way to solve it from one, sometimes it does not work for the other, and that is why we recommend that you try the solutions until one helps you. We will try to order the solutions from the simplest to the most complicated, although if the simple ones are not worth it, I am afraid that you will have to resort to those that are somewhat more complex.
What does it mean Ethernet doesn’t have a valid ip configuration?
This message has two concepts that you must understand. Ethernet is what the wired connection of the computer is called. When you connect your computer directly to the router, you are going to do it using an Ethernet cable , which allows you to maintain full speed without losing anything as sometimes happens with WiFi connections, not having to write names and passwords and, ultimately, saving you some complications that wireless connections can have.
The other concept that you must understand in the message is the IP address , which is the license plate that identifies your computer when it connects to the Internet , and the one that also identifies the websites you visit. The IP will be assigned to you by your Internet provider when you connect to their services through the router.
Therefore, what this message tells you is that something has failed when assigning an IP when you have connected to the router with your computer, and that this is causing your device to not be recognized correctly. Therefore, it tells you that it is an invalid IP, because it is not fulfilling its function correctly.
As we have told you at the beginning, the error can have different origins , such as that the subnet mask of the computer that indicates to which part of your home connection it is connected, has an incorrect value. It can also be due to an error in the gateway , which is the device that acts as a connection interface between devices or devices, and which is usually on the router.
It can also be a problem with the DNS , which is the system in charge of translating the addresses that you put in your browser such as Xataka.com to the IP to whose server your computer must connect. It can also be due to problems with Windows itself, since the Ethernet error may occur after an update, or another different and minor error, which is why you will have several solutions available and not all of them will work for you. Ethernet 2 doesn’t have a valid ip configuration this problem also comes when ethernet not working properly.
Steps for Fixing Ethernet doesn’t have a valid ip configuration Windows 10
- First, restart the router and the computer
- Update the network adapter drivers
- Reset your connection settings
- Reset TCP IP sockets
- Manually reconfigure Internet properties
- Change the DNS to see if it is fixed
- Don’t forget the Windows troubleshooter
LET’S BEGIN
First, restart the router and the computer
Before you get to fiddling with the settings, it’s best to start by trying the oldest and most widely used method in computing for troubleshooting. Turn everything off and turn it on again. This can help to solve small one-off errors that do not affect the configuration, and therefore cease to exist when you turn the router and the computer off and on again.
First try restarting the router by turning it off and on again, looking for the physical button that the device must have to have it turned on. If the error persists when the router restarts, try restarting the computer as well. If neither one nor the other works, try restarting both at the same time, leaving them off for a few minutes so that the computer does not try to restore previous configurations.
Update the network adapter drivers
Another of the first things to try is to update or reinstall your network adapters. To do this, the first step is to right-click on the Windows button at the bottom left of the desktop, and in the options that open, click on Device Manager.
You will enter a screen where you have a list with all the devices connected to the computer, the external and internal hardware.
In it, expand the Network Adapters section. When you do, right click on your network card and choose the Update driver option. If it doesn’t work, you can also try uninstalling it and restarting to reinstall it.
Reset your connection settings
Another easy solution is to reset your IP and DNS values. To do this, open the start menu and type CMD (1). You will see that the Command Prompt option appears , and in it you have to click on the Run as administrator option (2) that you will see in the right window or when you right-click on the Command Prompt in the results.
Once you are inside the Windows 10 command console, now you have to type the following commands. Write them by putting one first and hitting Enter to execute them, and so on with all of them:
- ipconfig /release
- ipconfig/flushdns
- ipconfig /renew
Reset TCP IP sockets
And since we are writing commands at the command prompt, we are going to use another to reset the sockets, which are what make two programs exchange data between them safely. To do this, first open the start menu and type CMD (1). You will see that the Command Prompt option appears , and in it you have to click on the Run as administrator option (2) that you will see in the right window or when you right-click on the Command Prompt in the results.
Now, disconnect the Ethernet cable from the computer , that cable that goes from the PC to the router. When you do, type the command netsh winsock reset and hit Enter.
When done, restart your computer and reconnect it to the router with the cable.

Manually reconfigure Internet properties
Your router will always automatically assign an IP, although this is something that can be changed, and by doing it by mistake you can end up seeing the failure that concerns us today. To check and fix it, press Windows + R and type ncpa.cpl. After doing so, hit Enter to open Network Connections settings.
Once you enter Network Connections , right click on where you put Ethernet. A pop-up window will open with several options, in which you have to click on the Properties option. You will need to give it administrator permissions to enter.
The Ethernet Properties window will open. In it, select the Internet Protocol Version 4 (TCP / IPv4) option in the list and click on the Properties button below it. In the window that opens, make sure you have the option Obtain DNS server address automatically activated,
which you may have mistakenly removed. After doing so, restart the router and try again.
Change the DNS to see if it is fixed
Once you have followed the steps on the previous screen, you can also try manually changing the DNS to some of our recommended DNS different from those of your operator. To do this, simply click on activate the option * Use the following DNS server addresses, and then write the DNS you prefer to use.
You can use OpenDNS, whose primary and secondary DNS are 208.67.222.222 and 208.67.220.220. In many support forums you will read that Google’s DNS is recommended, whose addresses are 8.8.8.8 and 8.8.4.4, and you also have others like Cloud flare 1.1.1.1 and 1.0.0.1. This change is just to check if the problem is here, then you can choose to stay in this DNS or get it again automatically , but as long as this change has fixed the problem.
Don’t forget the Windows troubleshooter
Finally, we can’t finish without reminding you that Windows 10 has a troubleshooter that could help you detect network problems and fix them by explaining what to do step by step. Go to Windows Settings and go to the Update & Security category.
There, in the left column, click on Troubleshoot , and inside click on the Run the troubleshooter button that will appear after selecting the Internet Connections option. Local area connection doesn’t have a valid ip configuration problem also solves by these above steps.
