I have a wireless network named "sweet-home". Ubuntu sees it all right and for some time everything went fine, but at some point in the dropdown menu "sweet-home" turned into submenu with two items in it: "sweet-home" and "sweet-home 1". Is there a way I can clean this mess up and just have one "sweet-home"?
In network indicator menu click on edit connections
Hare you can add/remove/edit your connections
