If you click "Off" or whatever for the connection, it *is* disconnected. What may happen though is that it re-connects if it's set to connect automatically. What you need to be looking at is likely the icon in Shell or in Unity to tell whether something is connected or not; but in any case if the connection is disconnected, it's not going to be used for the default route (and it shouldn't normally get autoconnected after that, or at least it doesn't with nm-applet).
Regardless, if you have reason to believe there's still an issue, don't hesitate to reopen by setting this bug report to "New". It would help if you could make sure you reproduce the issue, then provide the output of 'ip route list'. Note that any other connections may also be on and taking the default gateway, *all* wired connections will keep priority, in this case it may be eth0 as much as eth1. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/881660 Title: When an ethernet cable is connected to an otherwise empty switch I can't get internet over wifi Status in “network-manager” package in Ubuntu: Invalid Bug description: When an ethernet cable is connected to an otherwise empty switch I can't get internet over wifi I connect my computer to a switch that is not connected to any other device.
