🔹 Log in with the router’s username and password.
🔹 Locate the SSID and password settings, make changes, and save them.
🔹 Update the Wi-Fi settings on your PC and other connected devices.

Method 1: Check if Network Service Is Running

Windows uses a Network Service to automatically detect and manage network changes. If it’s disabled, you might experience connectivity issues.

Follow these steps to ensure the service is running:

Press the Windows Key and type “services” in the search bar.
Click on the Services application from the results. (It may take a moment to load.)
Scroll down and find WLAN AutoConfig Service.
Right-click → Select “Properties”.
Ensure the Status is set to “Running” and the Startup Type is “Automatic”.
If changes are needed, apply them and restart your PC.

If your Wi-Fi is still not working, move on to the next troubleshooting step.

Performing a clean boot ensures that third-party applications don’t interfere with your system, helping to resolve Wi-Fi connectivity issues caused by software conflicts.

Follow these steps to perform a clean boot on Windows 10:

1️⃣ Press Windows + R to open the Run utility.
2️⃣ Type “msconfig” (without quotes) and press Enter to launch the System Configuration window.

3️⃣ Navigate to the Services tab and check the box for “Hide all Microsoft services”. (This ensures you only see third-party services.)

4️⃣ Click Disable all to temporarily turn off all third-party services.

5️⃣ Click Apply, then restart your computer.

After rebooting, try connecting to Wi-Fi.

If the issue is resolved, a third-party service was causing the error. Enable services one by one to identify the culprit and keep it disabled.

⚠ Note: If the troubleshooter doesn’t detect any issues, don’t worry! It only checks for common errors, so your issue may require a more advanced fix.

🚀 If your Wi-Fi problem persists, move on to the next troubleshooting method!

Method 4: Reset IP Configuration & TCP/IP Settings

Your Network Adapter’s IP Configuration is typically set to automatically detect network settings, including the device-specific IP address assigned by the router. If flushing the DNS didn’t resolve the issue, you can try resetting your TCP/IP settings using Command Prompt.

How to Reset IP Configuration and TCP/IP on Windows 10:

1️⃣ Press Windows + R to open the Run utility.
2️⃣ Type “cmd” (without quotes) and press Enter to launch Command Prompt. (You may need admin permissions.)

ipconfig /release  
ipconfig /all  
ipconfig /renew

4️⃣ Stay in Command Prompt and enter these additional commands:

netsh int ip set dns  
netsh winsock reset

5️⃣ Exit Command Prompt and restart your PC.

After rebooting, check if the “Wi-Fi doesn’t have a valid IP configuration” error is resolved.

🚀 If the issue persists, continue with the next troubleshooting steps!

Method 5: Temporarily Disable Your Antivirus

Antivirus software can sometimes interfere with your internet connection, blocking essential apps and services, potentially causing the “Wi-Fi doesn’t have a valid IP configuration” error. You can test whether your antivirus is the cause by temporarily disabling it.

⚠ Important Note: Disabling your antivirus is risky. Only proceed if you’re aware of the security risks and have a backup of your system in case of any damage.

How to Temporarily Disable Your Antivirus on Windows 10:

1️⃣ Right-click on an empty space in the taskbar and select Task Manager.
2️⃣ If Task Manager opens in compact mode, click “More details” to expand the view.

7️⃣ Once installed, restart your computer and check if your Wi-Fi works without issues.

🚀 If the error persists, continue with the next troubleshooting method!

Method 8: Reset the Firewall

A firewall configuration issue can sometimes prevent your IP address from being validated, leading to the “Wi-Fi doesn’t have a valid IP configuration” error. You can reset your Windows Firewall to its default settings to resolve this.

Subnet Mask: 255.255.0

Default Gateway: 192.168.1.1

6️⃣ Switch to “Use the following DNS server addresses” and input the following:

Preferred DNS server: 8.8.8.8

Alternate DNS server: 8.8.4.4

7️⃣ Make sure the “Validate settings upon exit” option is checked, then click OK.

After making these changes, check if your Wi-Fi connection is now stable.

🚀 If the issue persists, proceed with the next troubleshooting method!

Method 10: Perform a Network Reset

Performing a network reset can help fix the “Wi-Fi doesn’t have a valid IP configuration” error by removing and recreating your network profiles. This process will remove all existing network profiles, giving you a fresh start, but keep in mind you’ll need to reconnect to all previous networks with the correct credentials.
