Another quick way to fix error 52 is by installing the latest Windows updates, as well as the newest driver versions.

Running outdated OS versions can cause various technical issues, including Internet connection problems.

Restart your computer and check if the issue persists.

• netsh winsock reset
• netsh int ipv4 reset reset.log

4. Turn off your antivirus/ firewall

If error 52 occurs immediately after you try to connect to your Wi-Fi network, try disabling your antivirus and firewall tools.

Sometimes, conflict issues between your antivirus solutions and computer drivers may arise and trigger various error codes, including the error that we’re focusing on in this article.

Don’t forget to enable antivirus and firewall protection afterwards.

5. Disable driver signature enforcement

Since error 52 comes with a description message reading that the digital signature could not be verified, maybe disabling it helps.

Here are the steps to follow:

1. Go to Start > open the shutdown menu and keep your mouse cursor on it
2. Press and hold the Shift key > click on the Restart option
3. Your Windows 10 computer will restart now displaying the Advanced Startup Options screen
4. Go to Troubleshoot > Advanced Options
5. Go to Startup Settings
6. Hit the Restart button
7. Windows 10 will restart > the Startup Settings screen should now be available
8. Press F7 to disable driver signature enforcement
9. Windows 10 will then boot to desktop.

Keep in mind that this solution allows you to disable driver signature enforcement only until the next reboot.

6. Delete the upper/lower filters from the Registry Editor

Before tweaking your Registry, don’t forget to first back it up. In this manner, you’ll be able to restore a working version of Windows in case anything goes wrong.

1. Go to Start > type “regedit” > hit Enter to open the Registry Editor
2. Locate the UpperFilters value under the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
3. Go to the Edit menu > Delete > OK
4. Now locate the LowerFilters value under the same key
5. Go to the Edit menu and delete this value as well
