How to fix the “Ethernet does not have a valid IP configuration” error

What does the “Ethernet does not have a valid IP configuration” error mean?

The “Ethernet does not have a valid IP configuration” error means that Windows can’t receive the IP address from DHCP (Dynamic Host Configuration Protocol), which automatically assigns IP addresses to devices connected to the network.

Your computer needs an IP address to connect to the internet and communicate with the outside world. It’s similar to your home address. If a postman doesn’t know where you live, he can’t deliver your mail; likewise, without a valid IP configuration, the internet can’t send you data.

There could be several reasons for this error: incorrect network configurations, outdated drivers, and more. However, this is not a serious issue and can be solved with even a limited technical knowledge. Just follow these steps to get back online.

Ways to fix the “Ethernet does not have a valid IP configuration” error

Restart your router

Turning your router on and off can work miracles. While this might seem a trivial solution, restarting your router usually solves nine out of 10 internet connectivity issues. When you turn off your router, make sure to count until 10 before turning it on. Additionally, you can also restart your PC.

Reset the network adapter

If the problem persists, you can reset the network adapter and refresh your IP configuration:

  1. Go to “Settings” > “Network & Internet” > “Status.”
  2. Networks and Internet
  3. Under the “Advanced network settings” section, click “Change adapter options.”
  4. Click Change adapter options
  5. Right-click the adapter and select “Disable.”
  6. Select Disable
  7. Right-click the adapter again and select “Enable.”

Configure your network adapter settings

Your device obtains an IP address automatically, but it’s worth checking if your settings are correct:

  1. Go to “Control Panel” > “Network and Sharing Center” > “Change adapter settings”.
  2. Change adapter settings
  3. Right-click on the Ethernet and select “Properties”.
  4. Select Properties
  5. Double-click on “Internet Protocol Version 4 (TCP/IPv4) .”
  6. Double-click on Internet Protocol Version 4
  7. Click on the “Obtain an IP address automatically” radio button.
  8. Click on the radio button
  9. Click on the “Obtain DNS server address automatically” radio button.
  10. Click “OK”.

You can also change your default settings manually and see if it helps to connect to the internet:

IP address:

Subnet mask:

Default gateway:

Preferred DNS server:*

Alternate DNS server: address.

Clear the network cache

  1. Type “cmd” in the Windows search bar and open “Command Prompt.”
  2. Type cmd
  3. Type “ipconfig/flushdns” and hit “Enter.”
  4. flush DNS
  5. Type “ipconfig/release” and hit “Enter.”
  6. Type “ipconfig/renew” and hit “Enter.”

This will clear your DNS cache on Windows, release your IP address, and renew it.

Troubleshoot Windows

Windows can identify connectivity issues and fix all kinds of problems. It doesn’t always help, but it’s not a bad idea to try:

  1. Go to “Settings” > “Network & Internet” > “Status.”
  2. Networks and Internet
  3. Under the “Advanced network settings” section, click the “Change adapter options.”
  4. Click Change adapter options
  5. Right-click on the adapter and select “Diagnose.”
  6. Click Diagnose

Update ethernet network adapter drivers

  1. Type “Device Manager”in Windows search bar.
  2. Type Device Manager
  3. Expand the “Network adapters” section.
  4. Right-click on the selected driver you want to update.
  5. Select “Update Driver.”
  6. Update driver

If you have tried all the options mentioned above and you still bump into the “Ethernet does not have a valid IP configuration” error, contact your internet service provider (ISP) directly for technical support.

How to prevent ISPs and other parties from spying on you

Your IP address links your online activities with your identity and location. The websites you visit, the services you use, your location history, search queries, and other sensitive information is all accessible to your ISP and other third parties.

This data is used to create a detailed profile of your habits, so companies can target you with online advertisements. If you want to avoid this and keep your information to yourself — use a VPN.
