How to Fix ‘Ethernet doesn’t have a valid IP configuration’ errors in Windows?

Fix ‘Ethernet doesn’t have a valid IP configuration’ errors: Windows might have been the most widely used and one of the most efficient operating system available in the present market.  Windows also has a record of strange error messages and notifications appearing all over the operating system. If you ever search for any error messages that Windows shows, you’ll get a number of forum posts, guides and questions with very heavy technical terms, which requires an in-depth knowledge of Windows to understand. Seems like Windows is working a lot with troubleshooting of Windows Errors, as a reason of which the troubleshooter of Windows 10 is that effective. The troubleshooter is mostly the solution to most of the basic errors in Windows 10.

But Windows Troubleshooter is not a complete solution for all of the errors, especially network connection issues. For Gaming or many other purposes, you might be using an Ethernet cable for establishing an internet connection on your PC. Ethernet, in fact, is more reliable than WiFi and is usually used where a stable connection is required. Ethernet also provides a faster connection than WiFi.

As Windows, Ethernet is also not perfect and has its own flaws. It presents a number of errors and problems, including an error that says that Ethernet doesn’t have a valid IP configuration. Most people don’t give a thought about IP addresses and that too for various reasons. First of IP addresses are dull and boring and require technical knowledge and they mostly exist in the background as they are not required or are not in general use for common creed. You will mostly see IP address written in an error message or a network problem, otherwise, IP address mostly stays in the background and works silently. The error message that usually pops up is regarding the validity of your IP address. So what does this error mean and what you should do? Proceed with the article to know about that.

What does this ‘Ethernet doesn’t have a valid IP configuration’ Error Mean?

So, basically every device connecting to the internet has an IP address which is provided by Internet Service Provider(ISP) and in a closed connection like a home network, a single IP address is shared by all of the devices connected to the internet. Usually, a router is used for that purpose. IP address makes it possible to track down the devices when and if needed. Think of this as a Resident address, the address of your house; it lets you and other people track down your house when and if needed.

So, whenever the error saying that your Ethernet connection doesn’t have a valid IP configuration, it means that Dynamic Host Configuration Protocol (or DHCP), a network protocol that automatically allows the server to assign IP addresses to the computers; is not being able to send IP address to the Windows operated device. Which in turn, cuts your connection to the ISP network and that as a result, leaves you with no internet connection.

This can be a pain in the ass as it hinders any kind of work that requires an internet connection. The cause of this error could be either of these two:

  1. Your ISP might be facing an outage in your area, in which, the best you can do is to call your ISP or wait for the problem to be solved.
  2. There could be issues with your PC or your modem.

So how to fix this error?

Well, you can do this by following either of the below-mentioned methods.

1. Simple Fixes:

We’ll be starting with some simple and easy to perform methods. These methods could also be seen as the methods you should Immediately take as soon as the error message is displayed before contacting your ISP or trying any advanced fixes as mentioned below.

2. Reboot:

The first method, as you would do in any other problem or with any other device, is to reboot the device or restart the device. As soon as the error is displayed on the screen, save your work in any of the opened applications and shut down the applications. Once you have saved all your work and terminated all the running applications, restart your PC. Make sure that when your PC reboots, the Ethernet cable is firmly plugged into your computer. Retest the internet connection and retry to establish an Internet connection through Ethernet cable. Keep moving through the steps if the same error message is displayed over and over.

3. WiFi Fix:

After going for the reboot, you have to make sure that it is a problem with your Ethernet connection, not the internet. To make sure, use your WiFi to connect to the internet. If everything goes well, then it surely is a problem with your Ethernet connection. But if you still receive the same error message, it could either be a problem with your network card or configuration. We’ll cover them both in Advanced options.

4. Driver Updates:

Now we need to check our network card for driver updates. It means asking your computer to look for any updates that could fix potential bugs and issues. To update your network drivers, click on Start button on your desktop and search for ‘Device Manager’ in the Search bar. This takes you to the Device Manager, displaying a full list of the hardware components of your device.

Click on the drop down the tab icon next to the Device Managers and look for the network adapter for your card. It could have been listed by different names. If you don’t know it, open the Start menu and search ‘ncpa.ol’ to open network preferences in Control Panel. Navigate to the name of your Ethernet connection, the same name will correspond to your Ethernet driver. To check for updates for your driver, right click on each listing and click on ‘Update Driver’ from the pop up menu.

As the update menu opens, click on ‘Search automatically for updated driver software’. You have to use any other PC with active internet connection to download the required updates for your network card. For doing this, right click on the corresponding network driver in the list shown in Device Manager and go to ‘Properties’. Click on the Driver tab and write the name and number of your version driver, and search for the written name and number of the driver online on any other PC with an active internet connection.

Download the latest updates available on the manufacturer’s website for the searched driver. Now transfer the driver update to your PC with a flash drive. Now, Right click on the driver name within the Device Manager and click on ‘Update Driver’. Now, click on ‘Browse my computer for driver software’ and navigate to the driver update you just transferred into your PC and select it. Then follow on-screen instructions to install the update and test once again, your device’s Ethernet connection.

5. Power Cycle:

This method is a pretty important solution. For this, you need to access your modem and router. Unplug the AC adapter from the back of each unit and wait for around ten seconds, and plug it back in. This will reset your modem and router. This type of reset will serve as the hard reset for both the devices and will fix the local network issues once the device is rebooted. If you do not have access to the modem and router, contact your network administrator and ask him to cycle your network as soon as everybody leaves the building.

6. Advanced Solutions:

If you’ve tried your luck with all of the above-mentioned methods and the error message still popups to screen, you need to try these advanced options. So read and understand carefully before going with any of the methods mentioned hereafter.

7. IPV4 Configuration:

The first thing you should do once you’ve tried all of the simple methods and the error message continues to pop up, is to view your network configuration to ensure that everything works as it should be with your PC’s network card. An account with the administrator rights is must for doing this. Once you have that, go to command prompt.

Once you are on the command prompt terminal, type the following phrase as written without quotes ‘ipconfig/all’ and press the Enter key. This loads a long list of information inside Command Prompt, including the name of your PC’s hostname, the states of your Ethernet and Wireless LAN Adapters and additional connection information for both Ethernet and LAN connection as well as your device’s Bluetooth connection information. Here we are looking for one specific piece of information. Under “Ethernet Adapter Ethernet’, look for an IPv4 address.

Your device should list an address using “192.168.x.x” where x represents the additional numbers in your IP address, if the IP address reads “169.254.x.x”, your device may be configured to use private networks because It is unable to find a standard IP address from your DHCP server.

Now, to fix this error, type “ncpa.ol” in the search bar on the start menu of your PC. Next, on the Network Connection Configuration window, right click on your network adapter icon and click on “disable”. Accept the prompt from Windows to allow your driver to be disabled. Wait for the icon to refresh. Now right click again and click on “Enable”. Now windows will reload both the network driver and your configuration and retest your connection too.

If the problem still remains, go back to the Network Connections window and right click on your Ethernet driver and click on “Properties”. Find “Internet Protocol Version 4” from the list of preferences displayed. Now select the “Properties” box underneath the list. You will find that “Obtain an IP address automatically” is selected by default. Now you select the other option and type the same IP address found in the Command Prompt settings above. Set the subnet mask to 255.255.255.0 and copy the default gateway numbers down (typically 192.168.x.x with x representing some variation of 0’s and 1’s).

Then, save preferences and exit Control Panel and retest your Internet Connection.

8. Resetting Your TCP/IP Settings:

If the above method didn’t work for you, then the next method you need to follow is to reset your TCP/IP settings to get your device back online. Start by opening the Command Prompt as an Administrator by right-clicking the command prompt icon and selecting ‘Run as Administrator’.

Now type the following commands as follows without the quotes: ‘netsh int ip reset c:\resetlog.txt’ and press Enter on your keyboard. This resets the connection. Now log in again and hopefully solves your internet troubles. Now reboot your computer and test your connection again.

9. Resetting Your IP Configuration Automatically:

One last step we can take to restore IP configuration on your computer is to clear the configuration files on your computer, to allow Windows to restore the Ethernet connection on your device. Proceed by running the command prompt as an administrator. Now you need to enter the following commands in the same order as mentioned below:

  1. Ipconfig/release
  2. Ipconfig/renew

This will refresh your IP configuration and an identification number that makes it easy to restore your certification on your device. After the process is complete, close the Command Prompt and try reconnecting to Ethernet.

10. Contacting Your ISP:

An easy way to figure out whether this is a computer error or a network error is to test your network with some other device or computer. If you are able to load web pages on your phone connected to WiFi, then it’s definitely an issue with your computer. If you’ve tried all of the above-mentioned methods and nothing works out for you, then the problem can be solved by contacting your ISP.

You can call him to ensure nothing is wrong with your local internet connection and ask him to send services to check your connection.
