How to Automatically Turn Off Wi-Fi Upon Ethernet Connect in Windows

information   Information
When you connect an Ethernet cable to a Windows PC which is already connected to a Wi-Fi network, Windows will automatically use the Ethernet connection by default instead of the Wi-Fi network. However, Windows does not automatically turn off the Wi-Fi connection when you connect an Ethernet cable. By defailt, you would need to manually turn off the Wi-Fi if you wanted to save power and/or battery life.

If supported by the driver of your wireless network adapter, you may be able to enable the "Disable Upon Wired Connect" setting to have Windows automatically turn off Wi-Fi when you connect an Ethernet cable. When you unplug the Ethernet cable, Wi-Fi will automatically be turned back on.

This tutorial will show you how to enable or disable to automatically turn off Wi-Fi when you connect an Ethernet cable to your Windows 7, Windows 8, or Windows 10 PC.

You must be signed in as an administrator to enable or disable the "Disable Upon Wired Connect" setting.

Here's How:

1. Press the Win+R keys to open Run, type ncpa.cpl into Run, and click/tap on OK to open Network Connections.

2. Right click or press and hold on your wireless network adapter (ex: "Wi-Fi"), and click/tap on Properties. (see screenshot below)
