We’ll explain why you see the message that Wi-Fi doesn’t have a valid IP configuration and how to fix it so you can get connected again.

What Is an Invalid IP Configuration?

Before we dive into the fixes, it helps to know a bit about why this error appears. In short, when you connect to Wi-Fi, your router assigns an IP address to your computer so it can get online.

If something goes wrong with the IP configuration, your computer and router won’t be able to communicate. For instance, your computer might try to use a different IP than the router expects it to. This prevents you from reaching the internet, and results in the “doesn’t have a valid IP configuration” error.

Let’s look at how to resolve this issue.

This tells your computer to release its current IP address back to the router’s pool of available addresses. Next, enter this command (press Enter to send it) to request a new address:

netsh winsock reset
netsh int ip reset

Try to get online again afterward.

5. Check for a Manual IP Address Setting

By default, your computer and router use a protocol called DHCP (Dynamic Host Configuration Protocol) to assign an IP address to your system without any manual intervention. If you’ve set a static IP address in the past and something changed, this can cause the “Wi-Fi doesn’t have a valid IP configuration” error.

To check for this, open Settings (the Win + I shortcut is handy) and browse to Network & Internet > Status. Here, select Change adapter options. In the box that appears, double-click on your Wi-Fi connection.

You’ll see a new window containing information about your connection. Click Properties at the bottom, then double-click Internet Protocol Version 4 from the list of options. This will open the properties window, where you can change IP settings.

Viruses and other malicious programs can sometimes mess with your internet settings to prevent you from getting online. While it may not result in this particular “doesn’t have a valid IP configuration” issue, it’s still worth a try.

Run a scan with Windows Defender or another antivirus you have installed on your system. If you have access to another computer that can get online, download  Malwarebytes and copy it over to the affected computer to run an anti-malware scan.

As another troubleshooting step, try disabling your antivirus and trying to get online again. Some third-party antivirus programs can interfere with normal network operations and block your network connection.
