Mobile broadband fails to automatically connect

[Steven Edgar]

I have a single Mobile Broadband adapter set up in Network Manager on Kubuntu 13.10. Under the General tab on "Edit Connection" for that adapter the "Automatically connect to this network when it is available" box is ticked. Whenever the adapter is connected it does not connect automatically, instead I have to click NM in the system tray, and then select the adapter from under "Previous connections", then click "Connect". Connection is then made successfully.

Adapter is a Huawei E156G, on the Three UK network.

Status changed to 'Confirmed' because the bug affects multiple users.

Have had the same problem with Ubuntu (both Saucy and Trusty) as well as Kubuntu Trusty.
