I've upgraded from 10.10 to 12.04. The situation: I plug the dongle in and enter the password. If I click 'Enable Mobile Broadband' and I get a notice on the top right saying 'GSM network. You are now registered on the home network'. At this stage I have not actually connected and when I click my broadband connection i see that 'Enable Mobile Boardband' is unticked AGAIN and I cannot connect to my broadbnad connection when I click it.
