Comment 2 for bug 178775

I'm using Gutsy Gibbon and I use the GUI in Network Manager to set a static ip (and gateway and subnet mask, etc.) for one of my ethernet interfaces. Unlike the original post, there is no message that says "changing interface configuration". I just hit OK, and then I close the dialog.

After doing the above steps, my internet no longer works. Before setting my ethernet device to a static ip, it was on roaming mode, and that worked fine. When I would run ifconfig -a on roaming mode, my ethernet device had a valid inet address, but after switching to static, I lose that. I'm not sure what other commands I should run to check to see what effect setting static ip had.

Also, I think there is a separate bug in NetworkManager, because when I change the said ethernet device back to roaming mode (to try to regain access to the internet) and close the dialog, it doesn't work immediately. I have to "sudo killall NetworkManager" and then "sudo NetworkManager" in order to restore my internet connection.

So I really have two problems:
* setting the static ip through the GUI in NetworkManager fails to work (and does not tell me how it is failing)
* Setting an ethernet device to roaming mode does not take effect until after I reboot NetworkManager

Note: I'm not sure how relevant this is, but I have two ethernet devices. Only one is connected with a live ethernet cable.
