Use Wireless Internet Without Taking Your Ethernet Cable Out
The following is a step-by-step process as to how you can use wireless internet without taking out your ethernet cable out.
- Open Network and Sharing Centre ("Network Status" in Windows 10).
- Go to "Change Adapter Settings" ("Change adapter options" in Windows 10).
- Go to properties of Local Area Network.
- Click on Internet Protocol version 4 and go to its properties.
- Click on Advanced. You will see a block checked there by the name of "Automatic Metric".
- Uncheck it and then enter 2 in that section.
- Now, Do the same for the wireless network but enter 1.
Save the setting, and you'll be able to use Wi-Fi even when your ethernet cable is connected to the LAN.
"Automatic metric" works by prioritizing the connection with the highest link speed. Manually changing the setting means you can specify which connection you want to give priority to. See "An explanation of the Automatic Metric feature for IPv4 routes".
