We mostly use an ethernet cable (wired connection) or a Wi-Fi connection to consume the internet on our PC/Laptop. Nowadays, plenty of users prefer to have both wired and wireless networks from the same ISP. So, if, in case, you’ve just connected an ethernet cable to your Windows computer, which is already connected to a Wi-Fi network, the Windows system will automatically start using the wired network (ethernet cable) by default instead of the Wi-Fi. As Windows doesn’t turn off the Wi-Fi connection when connected to a wired network, you must disable it manually. Here we’ve shared the steps on How to Automatically Turn Off Wi-Fi Upon Ethernet Connect in the Windows system.
Another thing worth mentioning is that if you’re not using Wi-Fi and it still turns on in the background, your PC power or battery life is wasted. So, you should turn it off manually if you’re not using it. The option will work if your wireless network adapter driver supports enabling the ‘Disable Upon Wired Connect’ setting to turn off Wi-Fi whenever an ethernet cable is connected automatically. That means whenever you unplug the ethernet cable, Wi-Fi will be turned on automatically.
