Home » Fix Windows 10 Wi-Fi Certificate error in 4 easy steps

There’s a variety of Wi-Fi errors in Windows 10 platform and some of them are quite hard to deal with. One problem, albeit not as common as others, concerns the Wi-Fi Certification and it prevents users from connecting to a network or access a certain website.

We enlisted some solutions below so make sure to give them a try.

Steps to fix Wi-Fi Certificate error in Windows 10

  1. Check Time & Time Zone
  2. Set the Windows Time service startup to Automatic
  3. Restore Advanced Network Settings to defaults
  4. Enable Hyper-V Hypervisor

Solution 1 – Check Time & Time Zone

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

Resetting the Automatic time and date settings should resolve the problem, but you might also go for the manual approach if it fails.

Here’s how to set the time and date to proper values:

  1. Right-click on Start and open Settings.
  2. Choose Time & Language.
  3. Disable and re-enable the time and time zone automatic settings.windows 10 wifi certificate error
  4. Restart your PC.
  5. If the problem persists, set the time and time zone manually.

Solution 2 – Set the Windows Time service startup to Automatic

Windows Time Service regulates and maintains the date and time synchronization on a network. This service should start manually, when necessary.

However, it can get into a stall and thus invoke the error at hand. Restarting this service should be enough, but you can also go for the Automatic Startup type which will ensure the service is always on as soon as the system boots.

Follow these instructions to change the Startup type for the Windows Time Service:

  1. In the Windows Search bar, type Services and open Services.
  2. Search for Windows Time service. Right-click on it and click Restart in the contextual menu.
  3. If the problem is persistent, right-click on the Windows Time service and open Properties.
  4. Change the Startup type from Manual to Automatic and confirm changes.

Solution 3 – Restore Advanced Network Settings to defaults

It usually isn’t necessary to meddle with the Advanced Network Settings, at least not for home users. And that’s how they should stay in order to address this issue. With one option being the only exception and that’s the “Warn about certificate address mismatch” which should be disabled.

Here’s what to do:

  1. In the Windows Search bar, type Internet Options and open Internet Options.windows 10 wifi certificate error
  2. Choose the Advanced tab.
  3. Click on the “Restore advanced settings“.windows 10 wifi certificate error
  4. Scroll down through the Settings list until you find the ” Warn about certificate address mismatch” setting. Uncheck the box.windows 10 wifi certificate error
  5. Confirm changes and reset your PC.

Solution 4 – Enable Hyper-V

Finally, we suggest enabling the Hyper-V system feature. This, of course, applies only to users who have issues with servers. These issues started after update to Windows 10 1803 so you can also roll back the update as your last resort.

If you’re not sure how to enable Hyper-V, make sure to follow the steps below:

  1. In the Windows Search bar, Windows Features and open “Turn Windows features on or off“.windows 10 wifi certificate error
