Wi-Fi Doesn’t Have a Valid IP Configuration Error – Permanent Fix

Are you getting tired of seeing the “Wi-Fi doesn’t have a valid IP configuration” error? Most Windows 10 users face this problem while trying to be online. You may feel being back in 1995 when 1% of the population could use the internet.

You can’t connect the computer or laptop to Wi-Fi without IP configuration. However, Windows troubleshooting only detects problems but can’t provide solutions. You need to solve the issue manually. Thankfully, there are many ways to fix the error message.

Let’s go through the article to learn all the possible solutions.


What Is Invalid IP Configuration?

Before proceeding into how to fix the error, let’s know what causes it. Generally, when you connect with Wi-Fi, the router assigns an IP address to the PC to be online.

But if there is an issue with IP configuration, the router can’t communicate with your PC. Especially when the PC tries to use a different IP address, it prevents you from accessing Wi-Fi. As a result, Windows display the error message due to invalid IP.

In short, it’s a network configuration issue when the network protocol layers (TCP/IP stack) work negatively that interrupts Wi-Fi service. However, there can be other reasons too behind it like,

  • Incorrect network settings.
  • Faulty network drivers.
  • Antivirus settings.
  • Hardware-related problems.
  • Poor network connection from the service provider.
  • Disabled Windows network services etc.

How To Fix “Wi-Fi Doesn’t Have A Valid Ip Configuration” Error?

Wi-Fi is surely important when you want to use the laptop in a different location. But encountering with connection problem is frustrating. But don’t worry, an invalid IP configuration error isn’t permanent.

As Windows only can troubleshoot problems but can’t provide fixes, you’ve to do it manually. Here are the 13 solutions for your problem.

1. Restart The Computer

Restarting the computer is the first troubleshooting solution that comes to mind to fix any issue. The “Wi-Fi doesn’t have a valid IP configuration” message can be a temporary glitch. You can quickly resolve it by restarting your system before trying other solutions.

2. Reboot The Router

Sometimes the router handling the IP address causes the error. If restarting the computer doesn’t fix your issue, you can reboot the router as well. In order to clear router glitches or caches, turn it off for a few seconds and restart from new to get online.

If this simple fix doesn’t clear the error even after power cycle everything, let’s move to some advanced solutions.

3. Release and Renew IP Address

You can correct the invalid IP error by releasing the current IP address and requesting a new one using the Command Prompt tool. To renew your IP address in Windows 10, follow the steps below:

  • Type command prompt in Search to open Command Prompt and right-click on it. You can also select Windows PowerShell (Admin) from the power user menu to open the command line.
  • Select Run as administrator.
  • In Command Prompt, type ipconfig /release and hit Enter from the keyboard. Don’t forget to put a space between “ipconfig” and “/release”.
  • Then type ipconfig /renew and hit Enter. Again, you need to put a space between “ipconfig” and “/renew”.
  • Finally, type exit and hit Enter.

Now, restart the computer to check if your problem has been resolved.

4. Reset TCP/IP

If renewing IP address didn’t help, try resetting Winsock or TCP/IP stack to set network settings to its default. Winsock is the technical specification defining how your computer’s network software accesses the network like TCP/IP.

Follow the steps below to reset TCP/IP:

  • Type Window PowerShell at the Search box, open it and right-click to select Run as administrator.
  • Type netsh winsock reset and hit the Enter button.
  • Then type nets hint ip reset and hit Enter.
  • Exit the command window and restart your computer.

Now, try to get online to see if it resolves the network connectivity issue.

5. Set Your IP Address Manually

DHCP or Dynamic Host Configuration Protocol server automatically assigns an IP address when you connect with Wi-Fi. So, if something is wrong with the static IP address you’ve set, DHCP can’t get a valid IP. Consequently, the “Wi-Fi doesn’t have a valid IP configuration” error may occur.

In that case, you need to set the IP address manually. Here how it’s done.

  • Open Settings from the power menu or press Win+I from the keyboard.
  • Select Network & Internet>Status.
  • Select Change adapter options.
  • Double-click on the Wi-Fi connection.
  • You can see a box with our Wi-Fi status. Click on Properties.
  • Double-click on Internet Protocol Version 4 (TCP/IPv4) from the list. It’ll open a window where you can change the IP settings.
  • Most people have the Obtain an IP address automatically button selected automatically. You need to enable Use the following IP address and provide an IP address, Subnet mask and Default gateway manually. Similarly, you can change the DNS settings too if necessary.
  • Hit Ok and restart your computer.

Hopefully, you can get online now by setting up a new static IP address.

6. Update Wireless Adapter Driver

As your specified problem involves a wireless network connection, you may need to check the adapter driver. Due to a faulty or outdated network driver, sometimes your computer can’t connect to the internet.

So, how’s about updating the wireless driver? Here’s the simple process.

  • Press Win+X from the keyboard and select Device Manager.
  • Click Network adapters to find your wireless adapter from the list.
  • Right-click on it and select Update driver> Search automatically for updated driver software.

However, it may not find any new driver. Rather you can check Properties by right-clicking on your wireless driver to see the manufacturer. So, you can update the driver directly from the manufacturer’s website.

7. Uninstall Wireless Adapter Driver

If updating the adapter driver can’t solve the issue, you need to uninstall it. Don’t worry because Windows 10 OS will automatically reinstall it when you start the system again.

In order to uninstall the wireless adapter, follow the steps below.

  • Type device manager in the Search or press Win+X and select Device Manager.
  • Expand Network adapters and find your wireless device.
  • Right-click the device and select Uninstall device from the drop-down.
  • Mark the box Delete the driver software for this device if available and click Ok to confirm the uninstallation.
