Disappearing Wi-Fi networks

Randomly disappearing Wi-Fi networks is a known problem in Windows 10, but it can be fixed. 

The first consideration is whether you’re using any VPN software – if so, this could be conflicting with Windows 10. Turn it off, and see if this fixes the issue. If so, obviously your VPN utility is the problem – make sure you’re running the latest version of the program, and if that doesn’t help, try using a different VPN.

If the issue isn’t anything to do with your VPN, there’s another solution to look at. Right click on the Start menu, and select Command Prompt (Admin), then type in: 

reg delete HKCR\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3} /f

Press enter, and now type in:

netcfg -v -u dni_dne

Then hit search. This should fix the issue and all available Wi-Fi networks should show up present and correct.
