PC keeps disconnecting from WiFi

If your Wi-Fi is working fine but your PC keeps disconnecting from it, then your PC’s network card may not be receiving full power. Windows has a built-in power saver option that gives less power to the network card. You need to disable this feature:

1. Go to Advanced settings in the Power Options.
2. Here expand Wireless Adaptor Settings and then expand Power Saving Mode.
3. Set this to Maximum Performance.
