I've deleted Wired Connection 1. How to set up new Wired Connection 1?
Create a wired connection called 'Wired Connection 1' and enter the device MAC address (mine is 5C:F9:DD:42:43:ED (eth0)) You may need to look it up based on your computer. Then make sure 'Automatically connect to this network when it is available' is on. Then you should be set. If you have any problems comment below.
