The process is wrong. It's expected behavior that the settings don't change immediately; since you can change the settings to any connection, not just the active one, and nm-applet needs to speak to NM to change the settings.
What you'll want to do is edit the connection settings, then click on the connection itself again via nm-applet: for instance, if it's a Wifi network, click its name again just above the "disconnect" menu entry and the connection will be re-established. Since this is already covered in NetworkManager, I'll close this bug as Fix Released. -- 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/297745 Title: Changing the IP address in NetworkManager should immediately change the IP on the interface Status in “network-manager” package in Ubuntu: Won't Fix Bug description: Changing the IP address on a manually configured Ethernet interface and clicking OK does not result in the IP on the interface actually changing. You have to unplug the cable and plug it back in. When changing the IP address, NetworkManager should change the IP on the interface (running the down/up interface scripts as appropriate).
