How To Fix The "Ethernet doesn’t have a valid IP configuration" Error
IP address (Internet Protocol address) allows devices to communicate with other devices on the Internet, on the IP-based network. IP address is the identity of a device on a network, you can think of it as a home or business address with a particular physical location with an address that can be identified by others. There are various different types of IP addresses, like private IP address, public IP address, static and dynamic IP address. Additionally, every type of IP address can be an IPv4 and IPv6 address.
If you are reading this, then most probably you got the error message saying that "Ethernet doesn't have a valid IP configuration". This error means that your Ethernet connection no longer has a valid IP configuration and Windows operating system is failing to receive the necessary IP address from the DHCP (Dynamic Host Configuration Protocol). Dynamic Host Configuration Protocol is a network protocol system that is responsible for enabling a server to automatically assign your computer an IP address for a specific network. If you are getting the "Ethernet doesn't have a valid IP configuration", it means that your computer cannot be assigned an IP address and you are unable to connect to a network, and you cannot connect to the internet.
Usually this error is caused by faulty, outdated or incorrect network adapter drivers or incorrect network configuration. In order to fix this error you may need to update or reinstall network drivers, configure network settings and to try some other fixes. In this guide we are going to show you how do to it by providing thorough descriptions with screenshots. Simply follow the steps and try out our provided methods one by one until you find the one that works for you.

Restart Your Computer And Router/Modem
We recommend you to start with the simplest solution that actually helped some users to fix this "Ethernet doesn't have a valid IP configuration" error. Save all your unfinished work and then shut down your Windows operating system. Additionally, we recommend you to unplug your modem or router from the power plug and leave it unplugged for a couple of minutes. Then plug your router (or modem) in again and wait until it finishes the startup (self test) process. Turn on your computer now and see if the "Ethernet doesn't have a valid IP configuration" error gets fixed.
This method includes entering and executing "netsh" commands into Command Prompt. Netsh is a command-line scripting utility that allows you to, either locally or remotely, display or modify the network configuration of a computer that is currently running. Netsh also provides a scripting feature that allows you to run a group of commands in batch mode against a specified computer.
The commands require an elevated Command Prompt opened with administrator privileges. To open elevated Command Prompt, type "command prompt" in Search and right-click on the "Command Prompt" result. Choose "Run as administrator" to run it with administrative privileges.
When you select "Run as administrator", a User Account Control prompt will appear asking if you allow the Command Prompt to make changes to your computer. Click "Yes".
Elevated Command Prompt will appear. In the Command Prompt window, type these commands:
netsh winsock reset
netsh int ip reset
Command Prompt will show a message saying that you must restart the computer in order to complete the reset after you execute the first command, ignore it and execute both commands by pressing Enter after each. Restart your computer and see if the "Ethernet doesn't have a valid IP configuration" error is now fixed.
Clear Network Cache
This method includes entering and executing "ipcofig" commands into Command Prompt. Ipconfig is a command-line tool that displays the current configuration of the installed IP stack on a networked computer. Using tool, we can flush and reset the contents of the DNS client resolver cache and renew DHCP configuration. Open Command Prompt as administrator again and type these commands and press Enter after each:
When all three commands are executed, restart your computer and see if this heled to fix the "Ethernet doesn't have a valid IP configuration" error.
Configure TCP/IP Settings Manually
If resetting TCP/IP and clearing network cache could not solve the problem, then you might want to try to configure TCP/IP settings manually. To do so, open the Run dialog box by right-clicking the Start menu and selecting "Run" from the contextual menu or simply by pressing Windows key + R.
In open Run dialog box type the "ncpa.cpl" command and press Enter on your keyboard or click "OK". This will open the Network Connections window for you.
In Network Connections window you should see all available connections, find the Ethernet connection, right-click it and select "Properties" from the contextual menu.
In Ethernet Properties look for "Internet Protocol Version 4 (TCP/IPv4)" or "Internet Protocol Version 6 (TCP/IPv6)", depending on which one you are using. Select (highlight) it and click "Properties".
If there is a configured static IP address and you are unable to connect to the internet, and you are getting the "Ethernet doesn't have a valid IP configuration" when using it, then try to switch to the "Obtain an IP address automatically" and "Obtain DNS server address automatically" options and click "OK".
If these options were set by default and you haven't done any configurations, then you can try to enter the static IP address details, like IP address, subnet mask, default getaway, the preferred and alternate DNS server. You can use our screenshot as an example. Click "OK" and restart your computer to see if this solution helped to fix the "Ethernet doesn't have a valid IP configuration" error.
Reinstall Or Update Network Adapter Driver
Device driver is software that informs the operating system and other software how to interact with particular hardware. It is rather like a translator between software and hardware, since they often are created by different manufacturers, companies, or people. The driver facilitates smooth communication between hardware and software. In most cases, computers are unable to send and receive data correctly without drivers. If the appropriate driver is not installed, the device might not function properly. To reinstall network adapter driver you will need to use Device Manager. To open Device Manager, right-click the Start button and select "Device Manager" result from the contextual menu or type "device manager" in Search and click the "Device Manager" result.
In Device Manager you will see a list of devices connected to your computer. Find "Network adapters", expand it and right-click on your networking device. Choose "Uninstall" from the drop-down menu.
You will be asked to confirm the uninstallation. Click "OK". Mark the "Delete the driver software for this device" checkbox if you see this option.
You will need to restart your PC for the changes to take effect. Restart your computer and see if it fixed the "Ethernet doesn't have a valid IP configuration".
If for some reason Windows could not or won't install the missing (uninstalled) drivers, then go to Device Manager again and right-click your computer name, select "Scan for hardware changes". It should detect missing drivers and install them.
To update your network adapter drivers follow the same steps and choose the "Update driver" from the contextual menu option when right-clicked the network adapter device.
You will be asked if you want to search for updated driver software automatically or to browse your computer for driver software. If you select the first option, then Windows will search your computer and the Internet for the latest driver software for your device. If you select the second option, then you will have to locate and install the drivers manually. Using this option requires having downloaded driver on your computer or USB flash drive. We recommend you to select the first option, select it and follow the instructions. If first option does not solve the problem, then download the latest network adapter's drivers from the manufacturer's website.
If you want, you can youse third-party software to update your drivers automatically. In this case we would recommend you to try our the Snappy Driver Installer. it is a powerful free driver updater tool for Windows that can store its entire collection of drivers offline. Having offline drivers gives Snappy Driver Installer the ability to have access to fast driver updates, even if there is no active internet connection. Snappy Driver works with both 32-bit and 64-bit versions of Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP. Drivers are downloaded through Snappy Driver Installer in what are called driverpacks, which are just collections (packs) of drivers for various hardware like sound devices, video cards, network adapters etc. It can also show duplicate drivers and invalid drivers and it separates the updates that require you to restart your computer so it would be easier to distinguish them from the rest. You can download Snappy Driver Installer from here.
