I am using a Qualcom Broadband (EVDO) dongle on Ubuntu 13.04. I have used this dongle well for a number of days on Ubuntu 13.04 but recently I had to do a fresh install of Ubuntu 13.04 but when I try to use the dongle the option for Enable Mobile Broadband keeps unchecking itself and I get a "not enabled" as the name of my connection. After a few tries of checking the Enable Mobile Broadband option I get this error :
"Creating Object path /org/freedesktop/NetworkManager/ActiveConnection/6 failed in libnm-glib"
