networking - Why do I have both eth0 and "Wired connection 1" in my 'Network Connections' list? - Ask Ubuntu


why have both eth0 , "wired connection 1" in 'network connections' list? don't both refer same device eth0?

this list accessible clicking 'edit connections...' menu clicking on network icon in upper panel area.

ifconfig shows have eth0, wlan0 , lo

one connection profiles of networkmanager, other actual interfaces/devices.

you can configure multitude of profiles, adding, modifying, deleting them. tell networkmanager "activate" connection on device. means, configure actual networking interface.

check nmcli connection vs. nmcli device
