How to fix Wi-Fi does not have a valid IP configuration on Windows.

Wi-Fi is great when it’s working properly. You can probably carry a device everywhere and have a high-speed Internet connection. But when it misbehaves, fixing Wi-Fi configuration errors on Windows can be a pain. Here are some solutions that you should try.

Restart your computer and router

Have you tried shutting it down and then turning it back on? It’s tech’s biggest cliché, and for good reason: Restarting your PC often solves a whole host of problems. In this case, you need to restart both your router and your PC. .

Locate the router (or combo unit) and unplug it for at least 30 seconds, then plug it back in. Be careful not to accidentally disconnect the Ethernet, fiber optic, or coaxial connections while handling power.

Then you need to restart your computer. The Start menu underwent a major cosmetic overhaul between Windows 10 and Windows 11. Follow the instructions for the version of Windows on your PC.
Windows 10

To restart Windows 10, click on the Start button, then on the power icon on the left, and finally on “Restart”.

Windows 11

Click the Start button, click the power icon, and then click Restart.

Reset Dynamic Host Configuration Protocol (DHCP)

DHCP should take care of automatically obtaining an IP address from your router, but nothing is perfect. Try to force your computer to re-obtain a new IP address from your router. You need to run PowerShell elevated.

Click the Start button, type “powershell” in the search bar, and then click Run as administrator.

Type the following two commands into Powershell:

ipconfig /version

ipconfig /renew

After running each command, you will see a bunch of texts related to the different network adapters. Each computer will be different, depending on the hardware at hand. The ipconfig/renew command can take 10, 20, or even 30 seconds to complete, so don’t panic if it pauses for a while before you start seeing things pop up in PowerShell.

Try to connect again.

TCP/IP stack reset

The Transmission Control Protocol and Internet Protocol, often referred to as TCP/IP, manage how information is divided into packets and then classified for delivery. It’s essential for most modern internet traffic, and when something gets corrupted or malfunctions, it can cause connection issues.

Run PowerShell as administrator, then type the following command in the window to reset the TCP/IP stack.

netsh int ip reset

There will be a bunch of “Reset, OK!” lines. in the PowerShell window if all goes well.

If the reset is successful, a group of “Reset, OK!” will be performed. will display.

Restart your computer then check if the error is still there.

Reset WinSock

WinSock is another part of Windows that allows your computer to communicate with devices on the Internet. WinSock can be responsible for network errors (including Wi-Fi). Resetting WinSock only takes a few seconds.

Run an elevated Command Prompt or PowerShell, then type netsh winsock reset in the window.

You will see “WinSock Catalog Successfully Reset”. After running the command, restart your computer and try Wi-Fi again.

Adjust your computer’s network and driver settings

Automatic DHCP Configuration

Your computer is configured to get an IP address automatically, unless you change it manually at some point. If you get the error message “Wi-Fi does not have a valid IP configuration,” configuring your IP manually may be causing the problem.

Click the Start button, type “view network connections” in the search bar, and then click “view network connections.”

You can also access it through the Control Panel if you want – Control Panel > Network and Internet > Network and Sharing Center, then click “Change adapter settings” in the upper left corner.

Locate your Wi-Fi network adapter, right-click on it, and then click Properties.

Scroll down until you find “Internet Protocol Version 4” (IPv4) and “Internet Protocol Version 6” (IPv6). Start by selecting “Internet Protocol Version 4”, then click “Properties”.

Select the Obtain an IP address automatically option, then click OK.

Repeat the Internet Protocol Version 6 process. Keep in mind that your IPv6 settings will all display IPv6 addresses, so don’t worry if the IP addresses look different.

Update your network drivers

Click the Start button, type “Device Manager” in the search bar, and then click Open.

You are looking for the category “Network Adapters”. Once you find it, click on the arrow and expand the list. What you see listed depends entirely on the hardware and software you’re running – whether you have a lot of things that require physical or virtual network adapters, such as a VPN, virtual machine, physical Ethernet port, and Wi-Fi adapter. You should expect a very busy menu.
