Why does my Windows 10 computer keep losing Internet connection?

If you find Windows 10 repeatedly drops the Wi-Fi connection without warning (and you’re sure there are no issues with the router), the problem could be caused by your network adapter’s power management settings. You need to revoke the permission which allows Windows to turn off the adapter to save power.
