How to Fix ‘Ethernet doesn’t have a valid IP configuration’ Error

The Ethernet does not have a valid IP configuration error means Windows couldn’t get an IP address from the network’s DHCP server.

Internet connectivity and interaction with other computers and the outside world need an IP address. Like a street address. A postal carrier can’t deliver your letter without a precise address. A wrong IP address prevents the internet from providing data.

Incorrect network settings and outdated drivers may have caused this problem. This is not a serious issue and can be rectified by anyone with basic technical skills. Just follow our instructions to reconnect to the internet.

How Do Ethernet Cables Operate?

Wired and wireless technologies are the two primary categories utilized to connect computers and establish communication channels.

As with a local hotspot provider, data is transmitted wirelessly without the need for wires. Users may interact with one another and connect to the Internet via Ethernet connections, which connect devices.

What to do if you see the error “Ethernet Doesn’t Have a Valid IP Configuration.”

Method 1: Rebooting your modem, router, and computer could be necessary.

Occasionally, restarting the affected hardware may fix this annoying issue. Before shutting off your computer, save your current work and any modifications you’ve made beforehand.

  1. To open the Start menu, choose Windows from the taskbar.
  2. Click the icon to access the Power menu and then restart. This will shut down and restart your device on its own without any more action from you.
  3. Log back into your Windows 10 user account after restarting your machine.
  4. Restart your network’s hardware after that.
  5. After turning it off, disconnect the modem or router for at least a few minutes. It is suggested to wait for at least 2 to 5 minutes to ensure a good restart.
  6. Reconnect it to the power source and wait for it to start. The LED lights should come on to indicate that the device is again operational and switched back on.

Check to see whether the Ethernet’s invalid IP address has been fixed. Check the ethernet cable if you’re using one. Check to see if switching the cable improves the connection.

Method 2: Disable Fast Startup

Due to the Fast Startup option, the Ethernet interface does not have the proper IP setup. Disabling Fast Startup is one remedy if you encounter an error stating that your Ethernet does not have a proper IP configuration.

This feature comes as standard on the majority of Windows 10 PCs, which reduces the time it takes to resume after being in hibernation or shutdown.

  1. Enter “control panel” in the search bar of your browser. Windows + S will launch the search bar if you wish to utilize the keyboard. Simply click the Control Panel’s icon to access it.
  2. Select the small icons or large icons view mode and then go to the Power Options area in the Control Panel to get all of the functions.
  3. From the menu that displays on the left, choose “Choose what the power buttons do”.
  4. Choose the supplied link to change the inaccessible choices. You may need to log in as an administrator in certain circumstances to do this.
  5. Go to the Shutdown settings menu, uncheck Turn on the speedy startup (recommended), and then click Save changes to turn off the feature. Disabling Fast Startup can be helpful if you’re experiencing issues with your Ethernet connection. 
  6. Click the Save Changes button to save the changes and restart the computer. Check to see if the issue persists when you reboot. 

Method 3. Your network card’s settings need to be adjusted.

By default, your router gives each connected device an IP address; you may modify this setting to use just one static IP address. It is advised that you try the following to fix the Ethernet, which does not have a suitable IP setup problem.

An instruction manual for configuring your network adapter is provided below:

  1. Press the Windows key, and R will open Run. In the box, enter ncpa.cpl, then press OK. The window for controlling network connections will open as a result.
  2. Right-click your Ethernet adapter to configure.
  3. In Ethernet Properties, double-click TCP/IPv4 to modify the protocol. This will launch the TCP/IPv4 Properties box when clicked. You should turn on the following features there: 
  • Find your IP address using a machine.
  • Automatically determine the DNS server’s IP address.
  1. If it fails, manually modify your IP address and DNS server. 
  2. Use the Internet Protocol Version 4 (TCP/IPv4) Properties to change the following settings. Substitute these values for the following IP address.
  • Enter the following IP address to connect to this computer:
  • The subnet mask we use is
  • Default router

When using the following DNS server addresses, then swap out the blanks with the necessary values:

  • The preferred DNS server is
  • Domain Name Server Replacement:

Select OK to commit the changes after you’re done changing them. Remember that Google utilizes these DNS server configurations. 

Method 4: Reset TCP/IP

This method needs the Command and the Command Prompt. Using this utility, network settings on a machine may be seen and modified. 

  1. To see the prompt, type “Command Prompt” into the “Search” box. A search box may also be accessed by pressing the Windows key and S.
  2. Right-click the option to open the Elevated Command Prompt. Another option is to right-click the Command Prompt icon and choose Run as Administrator. Select OK if you are prompted to confirm.
  3. When the UAC (User Account Control) prompts you, choose Yes to allow the software to change your device. You need to complete this to launch the program initially.
  4. To make the following commands effective, remember to hit Enter after each Command at the Elevated Command Prompt. 
  • Winsock state netsh reload 
  • Ip reset netsh int
  1. An error message will show up if you run the first Command without restarting the machine. You may safely ignore it at this point and go on to the second Command.
  2. Restart the computer after completing both procedures to determine whether the Ethernet connection still fails to establish a connection with a legitimate IP address.

Method 5: Be sure to delete all network history

The ipconfig command is specifically used in the Super User mode of the command prompt. The IP stack’s current settings are shown in the Command’s output. It may be used to clean the DNS client resolver cache and update the DHCP settings.

In the box there, type “Command Prompt” to find it. Click Windows + S to open a search box. Open the elevated command prompt by selecting Run as Administrator. Right-clicking Command Prompt and selecting Run as Administrator works also. If asked to confirm, click OK.

On the Elevated Command Prompt, enter the following commands: 

  1. Ipconfig /release
  2. ipconfig and flushdns
  3. IP Address Renewal Using IP Configuration

It would be best if you restarted the computer after inputting the instructions to check whether the issue has been fixed.
