How to fix "Ethernet does not have a valid IP configuration"

"Ethernet does not have a valid IP configuration" Have you come across this error message and you don't know what it means and how to fix it? This is a mistake quite common that can appear to us for no apparent reason. In this post we will explain how to solve the problem easily.

This error message can be caused by several reasons, there is no single cause. Therefore, we are going to offer you several solutions that you should try until the problem is corrected. Let's see below some methods that can help you. But first, let's see what does it mean "Ethernet does not have a valid IP configuration."

What does it mean "Ethernet does not have a valid IP configuration"

To understand this message, you must first understand what is ethernet. It is the wired connection of the computer, that is, the internet by cable. The moment you connect the computer directly to the router to use the internet, you are using a Ethernet cable.

This allows you to maintain all the internet speed, which, unlike the WiFi connection, does not lose that connection speed. In addition, you do not need to enter the password to access the WiFi. In short, using an Ethernet cable allows you to obtain a higher internet speed and save steps such as searching the network and accessing it using a key.

Once you are clear about what Ethernet is, you should understand what that "valid IP" address looks like. The IP address is a set of numbers that identifies your computer when you connect it to the internet. This IP is assigned by the Internet provider when you connect to the Internet through the router.

So, the problem is that something has gone wrong at the time of assigning an IP when you have connected to the router with your computer. Consequently, your device is not recognized, that is, you do not have a valid IP. Now that you know what the error is, let's proceed to see How to solve it.

How to fix the error

Restart the router and the computer

The first step is the simplest, but we should not ignore it, as it is usually the fastest solution to the problem. Before going into configuration topics, restart your routers, this tends to correct specific problems on certain occasions. First, restart the device by turning it off and on again (with the button that incorporates the router).

If after performing this step the error has not been corrected, test restart the computer as well. You can also choose to restart the router pressing that little button that is usually identified as «reset». It is a small plug that you will have to press for a few seconds using a very fine utensil, as the button is very small.

Update the drivers or network adapter drivers

Another method that can be very useful to solve the error is update or reinstall network adapters. To do this, follow these simple steps:

• Right click on the Windows button at the bottom left of the desktop
• Click on "Device Manager".
• You will enter a screen where you have a list with all the devices connected to the computer.
• Click on the Network Adapters section.
• Right click on your network card and choose the Update driver option.
• If it doesn't work, you can also uninstall it and reboot to reinstall.

Reset your connection settings

You can also try resetting your IP and DNS values. To do this, you must follow these simple steps:

• In the start menu type: CMD and click Command Prompt.
• Right click and hit the Run as administrator option.
• Once you are inside the Windows 10 command console, type the following commands (write them by putting one first and pressing Enter to execute them, and so on with all of them):
• ipconfig-release; ipconfig-flushdns; ipconfig-renew.

Reset TCP IP sockets

In the same console that we have shown you in the previous step, we can reset the sockets. These are what make two programs exchange data safely with each other. To do this, do the following:

• Disconnect the Ethernet cable from the computer.
• In the console, which you will have open and run as administrator, type the command netsh winsock reset and hit Enter.
• When done, restart your computer and reconnect the Ethernet cable to the router.

Disable Quick Start

Another solution for this common error is disable Quick Launch. This is one of the Windows functions that reduces startup and startup time. To disable it, you must:

• Right click on the Windows Key and select Power Options.
• Select Start / Stop and Sleep on the left
• Tap Additional power settings.
• Click Choose the behavior of the on / off buttons on the left side of the window.
• Select the option to Change settings currently unavailable.
• Now remove the check: Enable fast startup (recommended).
• Once you turn off the Quick Launch, click on Save Changes and close the currently open window.
• Reboot the system and see if the problem persists.

Reconfigure Internet properties

Tu routerAs we have said, it assigns an IP to the computer, although this can change and give an error. Check that this is not happening by following these steps:

• Press Windows + R and type ncpa.cpl and hit Enter.
•  The Network Connections settings will open.
• Right click on where to put Ethernet.
• Click on the Properties option.
• In this window select the Internet Protocol Version 4 (TCP / IPv4) option from 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.
• Restart the router and see if the error persists.

If with these methods that we have detailed above the problem persists and the error continues to appear, we recommend that you contact your network provider and explain the problem, they should know how to solve the problem or they will send you a technical to correct the error.
