• WiFi not working on Windows 10, 64-bit system

If you are experiencing one of the WiFi problems listed above or any other WiFi problem, the solution  below might help resolve the issue.

Reason for WiFi problem

Your Windows 10 WiFi problem might be triggered by unsupported VPN software installed on your PC. If you have an old VPN client like Sonic Global Client or Cisco VPN client, then it is likely your WiFi problem is caused by this piece of software.

Microsoft has also stated that if you have old VPN software installed on your Windows 8.1 system, which was also present in your system during the Windows 10 upgrade, then problems are likely to occur. This happens because the older version of software has Filter Drivers that are not upgraded properly when you migrate to Windows 10, leading to WiFi problems.

4. Enter the command given below at the Command prompt and hit Enter

netcfg -v -u dni_dne

5. Restart your PC

After taking the above actions, you should find the WiFi settings are now available and you can connect to your required WiFi network. If this solution does not solve the Windows 10 WiFi issue, you need to use the Compatibility mode to resolve WiFi Driver problems.
