System hacks: plug the Internet cable wireless adapter automatically save energy

We are often accustomed to choose Wi-Fi or network cable connection to use our laptops in different places, and we do not deliberately turn off the wireless network adapter when we do not use Wi-Fi, and Windows 10 does not automatically turn off the wireless network adapter by default. If you want to save more power, besides turning off the wireless network adapter manually, we can also make the wireless network adapter switch to off or energy-saving state automatically when you plug in the Internet cable through the settings or with the help of third-party software.

1. Set it manually in Windows 10

Right-click the network icon in the system tray to open the “Network and Internet” settings window, and click the “Status” option. In the Network Status window, click “Change adapter options” (Figure 1).


Next, in the Network Connections window, right-click on the WLAN connection and select Properties, which will then open the WLAN Properties dialog window (Figure 2).


In the WLAN properties dialog window, click the “Configure” button under the “Network” tab to open the properties dialog of the wireless network adapter. Switch to the Advanced tab of the wireless network adapter properties window and look for the “Sleep when WoWLAN is disconnected” option in the Properties section list. Select the entry and change its value from the default “Disabled” to “Enabled” from the “Value” drop-down list on the right (Figure 3). Since using the default “Disabled” setting will keep the wireless adapter in a power-consuming state even when the WLAN is not in use, when this setting is changed to Auto Sleep, it will serve the purpose of energy saving; and when the adapter receives a specific wake-up command, it will automatically wake up from sleep. When set to enable, Windows 10 will automatically switch the Wi-Fi adapter to sleep whenever a network cable is connected to the computer and the WLAN connection is automatically disconnected due to the priority of using the Ethernet connection.


It should be noted that the content in the “Properties” list of the “Advanced” tab may vary for different categories of wireless adapters, but generally there will be an option to save energy or automatically disable the relevant option. If the adapter has a Disable Upon Wired Connect option, set it to Enable to automatically disable the wireless adapter for the purpose of saving energy. If the wireless adapter is an external USB wireless card, you can set “Selective Suspend” and “Selective Suspend timeout”. This also allows you to temporarily suspend the card to save power when it is not in use.

2. Use third-party software to set up

In addition to the manual setting, we can also use BridgeChecker software to implement the Wi-Fi adapter auto shutdown function when Ethernet is available.


When installing BridgeChecker software, four options will pop up, the middle two options are whether to disconnect wireless automatically when connected to the network cable, and whether to connect wireless automatically when disconnected from the network cable (Figure 4). After installation, the above automatic functions can be achieved as long as the software is in automatic operation.
