Fix #8: 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 maximum wireless users. Once you manage to increase the maximum number of users, try and see if the valid IP configuration problem has been fixed.

Fix #9: Check for a Conflict With Your Antivirus

In some cases, your third-party antivirus could be interfering with the Wi-Fi IP configuration, network settings or network adapter. 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.

Fix #10: Set Up Your IP Address Manually

The IP address of each PC will be assigned automatically whenever you experience issues with your network. Reset network settings to fix the error.

  • After you’re done, click the OK button.

Fix #11: Check to Make Sure Your DHCP Is Turned On

If working on your wireless adapter driver did not solve the problem, you can check this method. Sometimes, you may have turned off your DHCP unknowingly. This causes problems with your connection as a result. To fix, simply turn on your DCHP.

  • Make sure that DHCP is turned on
  • Select Network Connections.
  • Locate your wireless network adapter, right-click and select Diagnose.
  • Diagnose network connection. Check DHCP is not enabled for WiFi.
  • Wait for the scan to finish.
