Many Windows 10 users have reported problems with WiFi after upgrading to Windows 10, the most common problems are set out below:

• WiFi button on Windows 10 not working
• No WiFi settings or an option to sign in to WiFi network
• No WiFi adapter found
• 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.

Solution to WiFi problems in Windows 10

1. Right click on Start Menu
2. Select Command Prompt(Admin) from the drop-down menu
3. Type the following command and hit the Enter key

reg delete HKCRCLSID{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f

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.

8. This will start the Program Compatibility Troubleshooter wizard that will check for the issues

11. Click Next
12. Select Windows 8. (You have upgraded from Windows 8 and WiFi drivers worked well in that version of Windows.)
13. Click Next
14. Click Test the program
15. Follow the on-screen instructions and in most cases the WiFi problem will be resolved
16. If the program is successful, Click the option “Yes, save these settings for this program” at the end of the program
