I just tried to reproduce this. In my case the interface was not downupped and the new settings were not applied when I edited the live connection. To get the new settings applied I had manually to dis-and- re-enable the interface.
But the important thing is that it still takes a downup to activate new settings. It's a legitimate request (that new settings be applied with downupping) but it's difficult to implement and I wouldn't expect it to be implemented soon. -- 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/979372 Title: When changing from "DHCP" to "DHCP (addresses only)" please reconfigure the interface without an unnecessary downup Status in “network-manager” package in Ubuntu: New Bug description: To reproduce: 1. Open network manager. 2. Open the current network connection. 3. Change it from "DHCP" (the default) to "DHCP (addresses only)" and enter some DNS servers. 4. Accept all changes. What happens: All connections through that interface are dropped and then the interface comes back up with the new addressing. What I expect to happen: The new DNS addresses should be used without dropping existing connections.
