By default, Windows will automatically select a wired ethernet connection over a wireless connection when a cable is connected to your PC. (This is done for quality and speed purposes) Although the WiFi adapter isn’t being used, it continues to run in the background, needlessly draining battery power. This guide will show you how to configure your Windows 10 computer to automatically disable your WiFi Adapter whenever a Wired connection is being used.

Because wireless connections are the easiest way to connect devices to the Internet they have become far more popular than Wired connections. What a lot of people don’t realize though is that wired connections are way faster and far more reliable than wireless connections. Even if you are only a few meters away from a WiFi router you can’t compete with the speed of a cabled connection. 

Connecting your Laptop to a wired connection rather than a WiFi connection is also a great way to reduce how much power your battery uses. Obviously, this isn’t always going to be an option but is something to consider in the future. It’s also important to know that even if your computer is connected to a network or the Internet via Ethernet your WiFi adapter is still functioning in the background draining a substantial amount of power. The good news is that a lot of modern Network Adapters now allow you to configure how the two network connections interact with each other.
