WiFi problems tend to occur when you’re actively using your desktop. Your WiFi signal may drop, it may disconnect at random, or it may refuse to connect altogether. Other problems are easier to isolate e.g., when you lock your screen and the WiFi disconnects.
This isn’t intended default behavior though the WiFi can be set to disconnect on system lock. If your WiFi is disconnecting each time you lock the system, or the system locks automatically, you need to fix a configuration in the registry.

WiFi disconnecting on system lock is a very specific bug with a specific solution. If it persists after you’ve applied other fixes, you can try resetting the network adapter.

To run the network troubleshooter;
- Open the Settings app.
- Go to the Update and Security group of settings.
- Select Troubleshoot.
- Click Network Adapter.
- Apply any and all fixes that it recommends, and restart the system.
This is an old Windows 10 bug that crops up randomly after system updates or driver updates have been installed. It happens because an update changes something related to the settings in the registry or, they are not set correctly when you install your OS. This fix solves it definitively and it doesn’t reappear.
