There are several Wi-Fi bugs on the Windows 10 platform and some of them are quite difficult to fix. One issue, though not as common as others, involves Wi-Fi certification and prevents users from connecting to a network or accessing a particular website.

We’ve listed a few solutions below, so be sure to try them out.

How do I fix Wi-Fi Certificate error in Windows 10?

  1. Check the time and time zone
  2. Update your network drivers
  3. Set Windows Time Service Startup to Automatic
  4. Reset advanced network settings to defaults
  5. Enable the Hyper-V hypervisor

1. Check Time & Time Zone

  1. Right click on Start and open Settings.
  2. Choose Time and language.
  3. Deactivate and reactivate automatic time and time zone settings.

4. Restart your PC.
5. If the problem persists, set the time and time zone manually.

Let’s start by making sure the date and time are set correctly. This seemed to be a problem for some users, due to the discrepancy between the system and regional time.

Resetting the automatic time and date settings should solve the problem, but you can also go for manual focus if it doesn’t work.

2. Update your network drivers

Certificate errors with Wi-Fi and Ethernet connections can also be caused by outdated network drivers. Therefore, use a third-party driver updater like DriverFix to easily fix the problem immediately.

The program is portable, which means you just need to download it and run it directly for the client. It will then proceed to scan your system for outdated, corrupted or missing drivers and then repair them automatically.

DriverFix is packed with libraries of all known drivers and as long as you are connected to the internet you can access the latest versions of the required drivers.

3. Set the Windows Time service startup to Automatic

  1. Type Services in the Windows search bar and open Services.

2. Search for the Windows time service. Right-click it and click Restart from the context menu.
3. If the problem persists, right click on the Windows time service and open Properties.
4. Change the startup type from Manual to Automatic and confirm the changes.

The Windows Time Service controls and maintains date and time synchronization on a network. This service must be started manually if necessary.

However, you may get stuck and thus trigger the respective bug. Restarting this service should be enough, but you can also opt for the Automatic Start type, which ensures that the service is always running as soon as the system boots.

4. Restore Advanced Network Settings to defaults

  1. Type Internet Options in the Windows search bar and open Internet Options.

5. Confirm the changes and restart your PC.

Usually, you don’t have to bother with advanced network settings, at least not for home users. And that’s how they should stay to deal with this problem.

With one option as the only exception and that is the certificate address mismatch warning, which should be disabled.

5. Enable Hyper-V

  1. Open Windows features in the Windows search bar and check Turn Windows features on or off.

2. Check the Hyper-V box to enable it.

3. Confirm the changes and restart your PC.

Finally, we recommend enabling the Hyper-V system feature. Of course, this only applies to users who have server problems. These issues started after upgrading to Windows 10 1803, so you can also roll back the upgrade as a last resort.

You should. If you have any questions or suggestions about Wi-Fi certificate errors, we recommend posting them in the comments section.
