How to Fix: WiFi Doesn’t Have a Valid IP Configuration

Sometimes the TCP/IP network protocol layers work against each other and create problems with your Internet. This error can occur even if you are using an Ethernet connection. Usually, you had Internet connection issues and decided to run the Troubleshooter. Instead of fixing the error, the Troubleshooter tells you there isn’t a valid IP configuration.

What Causes the WiFi Doesn’t Have a Valid IP Configuration Error?

Unfortunately, there isn’t just one simple fix for this error. There are many different reasons the Troubleshooter could be telling you this is wrong including the following:

  • You need a new IP address for your computer
  • You need to reset the TCP/IP
  • You need to update drivers or uninstall drivers that could be interfering
  • A third-party app is interfering with your connection
  • Your antivirus software is preventing you from connecting to the Internet
  • Incorrect network settings

Since there are many reasons you could see the WiFi doesn’t have a valid IP configuration error, we will walk you through methods to help you deal with each underlying cause.

Step #5

The computer should perform an automatic search. If your driver is up-to-date, you will see a message stating you already have the best driver installed for that device. Otherwise, the computer should automatically update the driver. Close the pop-up window once the search (and update if needed) is finished. Return to the device manager window (and Step #2) and follow the instructions for the next device until you have checked for driver updates on all the devices that are listed.

Do a Clean Boot

If third-party apps are interfering with the connection, restarting the computer without these apps running should resolve the matter. A clean boot reboots the computer with only necessary Microsoft apps running. A clean boot is not the same thing as booting into safe mode.

Step #1

Log as an administrator. Once you have logged in, press the [R] key and the [Windows] key at the same time to open the Run box. Type “msconfig” in it without quotation marks, and click the “OK” button.

Change the Number of Allowed DHCP Users

The steps for changing the number of DHCP users are different depending on the router you are using. You will need to consult the manual for the router to learn how to increase the number of users.

Check for a Conflict With Your Antivirus

In some cases, your third-party antivirus could be interfering with the IP configuration. The only way to confirm this is to uninstall the antivirus and see if the error is resolved. If it is, you need to consider using a different antivirus product.
