How to Fix ‘Ethernet does not have a valid IP configuration Error’ Issue – Guide
If you have a computer and an IP address, the computer can connect to the internet. If your home has a modem and router, and if there is a problem with getting an IP address from the network, you may see this error.
Ethernet not having a valid IP configuration error can cause problems for many people. This can be caused by a variety of reasons, such as faulty network adapter drivers or incorrect network configuration. In this guide, we will walk you through various fixes that will help you to get rid of Ethernet not having a valid IP configuration error.

Sometimes it can be caused by this – the boot process goes beyond the steps necessary to get the correct IP configuration. Press WIN + S and go to Control Panel. Now select Control Panel from the results list. Go to Power Options and select “Choose what power button does.” Select Change currently unavailable settings and uncheck Fast startup. ..
Configure your network adapter settings
If your router has a static IP address system, you can assign it yourself by using a DHCP client.
ncpa.cpl is a command line tool that can be used to view and change the settings for the National Computer Emergency Plan (NCP).
Right-click on the network adapter and select “Properties.”
Under “TCP/IP Protocols” on the properties window, find TCP and click properties. On the “TCP” tab, under “Protocols” you will see TCP. Click on it to open the TCP Properties window. Under “General” you will see the following: -Source IP: The IP address of the computer that initiated the connection -Destination IP: The IP address of the computer that you are connecting to -Port: The port number used by TCP (default is 25) -Sequence Number: A number that is incremented for each packet sent by TCP (used to prevent data loss) ..
If you are using a computer to access the internet, you may want to try setting your own IP address. If you are in a pattern home network, try 192.168.1.180. If you are on a specially configured network, talk to your network administrator about how to set up an IP address automatically for your computer or device.
If you’re having trouble getting your router to assign an IP address automatically, try changing the address to auto-assign and waiting for your router’s DHCP server to be configured correctly. ..
Restart your router
If you are having problems with all your devices connecting to the internet and your PC says “Ethernet does not have a valid IP configuration” – try restarting your router. Turn your modem, router and devices off and on (turn them off and on again, from the wall to your hands (modem, router, device).

Uninstall your ethernet card from your computer.
If you don’t have the drivers from your OEM’s website, you can get them from a Bluetooth transfer or USB device.
Try forcing IPv4 by disabling IPv6
IPv6 addresses follow the following convention: xxx.xxx.xxx.xxx. As you can imagine, with so many devices connected to the internet, having millions of different address combinations might not be enough. So we created IPv6, which allows for billions and billions of different address combinations. However, there are some infrastructure issues, especially with older devices that need to be solved before IPv6 can be fully implemented on all devices. Sometimes disabling IPv6 can give you a usable IPv4 address and go back to the internet.
Open your network and sharing center and change adapter settings.
Select “Properties” and then “Connection Properties.”
Disable IPv6 on your computer. ..
Assign a MAC address to your network card
MAC address conflict is when two MAC addresses are assigned to the same device. This can happen because the device was bought new, or because it was given to the user as a gift. If your ethernet isn’t receiving an IP configuration, it could be a symptom of a MAC address conflict.
Administrators are people who have power over something. They can make decisions, change things, and control what people can do. Administrators can be found in many different places, but the most common place for administrators is in organizations.
Open the command prompt and type “netstat -an” to see active network connections.
To search for a network adapter, you need to find its “physical address value”. This is the number that corresponds to the adapter’s physical location on the computer. To find this number, you can use a variety of methods, such as using a computer’s built-in hardware or software tools.
Your network card/router will now try to connect to the internet. If it succeeds, you’ll see a message like this: “Internet connected.” If not, your network card/router may be defective and needs to be replaced.
Enable DHCP
DHCP is a service that helps your computer find an IP address. If you’re not using DHCP, your computer might not be able to find an IP address on its own. This can cause problems, so make sure you’re using DHCP if you have a home or office network. You can also enable the option “Obtain an IP address automatically” in your PC or device’s network configuration if you want to get an IP address automatically.
Reinstall drivers for your network cards in compatibility mode
If you have an old network card, it may not be compatible with Windows 10. You can find the driver installer and run it in compatibility mode for Windows 8. ..
