When you connect an Ethernet cable to computer, it automatically connects to the internet using Ethernet connection, instead of using the Wi-Fi Network.
However, the Wi-Fi network still remains open and you will have to manually switch off Wi-Fi, in case you do not want both Wi-Fi and Ethernet connections being active at the same time on your computer.
Luckily, it is possible to automate this process and make your computer automatically Turn OFF Wi-Fi, whenever an Ethernet cable is plugged in to the computer.
Note: The steps provided below work only if the Network Adapter Installed on your computer supports this feature.
Turn OFF Wi-Fi When Ethernet Cable is Connected
Make sure that your computer is connected to Wi-Fi and follow the steps below to make your computer Automatically Switch OFF Wi-Fi, as soon as it is connected to a wired Ethernet Network.
1. Right-click on Wireless icon > click on Open Network and Sharing Center option in the menu that appears.
Note: If you do not find the Wireless Icon in the Taskbar, it will be available in the System Tray.
2. On Network and Sharing Center screen, double-click on the active Wireless Network Connection on your computer.
3. On the next screen, click on Wireless Properties button to open Wi-Fi Properties screen.
4. On Wi-Fi Properties screen, click on the Configure button located below the listed Wireless Adapter.
5. On the next screen, switch to Advanced tab, select Disable Upon Wired Connect option in the property box, set its value to Enable in the Value Field and click on OK.
From now on, whenever you connect an Ethernet cable to the computer, you will find it automatically turning OFF the Wi-Fi Network.
Note: If the “Disable Upon Wired Connect” option is not available, it is likely that the Network Adapter on your computer does not support this feature.
