I just updated the system with pacman -Syu and after rebooting now my pc is auto connected to a cabled ethernet connection called ’ lo ’ and won’t disconnect and/or eliminate. I have no cabled connection but it seems it is an activity of data exchange. internet doesn’t works and I can’t switch on the usual wi-fi connection from the settings windows.
Because of the loopback interface’s somewhat unique characteristics, NetworkManager traditionally treated it specially. That basically meant it ensured it’s up and that’s about it.
In the new version of NetworkManager, loopback interfaces are less special. While it’s still a little special – it will be configured even if there’s no connection profile for it – it’s now possible to actually activate a connection profile on a loopback interface. It behaves a lot like on an actual physical interface with some interesting properties. With the loopback interface always guaranteed to exist in one instance, a connection on a loopback interface can be used to specify configuration that’s always supposed to be applied.
Okay why does it still show connected when I’m completely disconnected and ethernet is unplugged. My WiFi is off but maybe it’s still using it since i can’t pull the plug unless i uninstall the drivers?
I understand that but i just thought it wouldn’t show it’s connected unless i actually had an internet connection. But, I guess the connection is actually the network card itself since that is what the loop back is.
Edit: I wasn’t aware of this change so it threw me also. It’s just odd to see this since it’s never been there in the connection before shown like this.
