After suspending my laptop while mobile broadband was connected and resuming, the mobile broadband connection doesn't come back up and I need to log out and log back in again to be able to use it again. This is a mobile broadband connection on Vodafone contract using a data SIM with the Lenovo X1 built-in 3G.
Steps to reproduce:
1. Connect to mobile broadband
2. Suspend the computer (e.g. by closing the lid)
3. Resume the session (e.g. by opening the lid and unlocking the computer)
4. Mobile broadband does not reconnect
5. Open network menu to re-connect: two entries are shown under Mobile Broadband: one that is enabled, one that is greyed out
6. Click on the enabled entry under Mobile Broadband
7. A notification bubble appears saying that mobile broadband is disconnected; the entries in the network menu revert to the normal entries before step 1 above
8. Open the network menu again and click on the mobile broadband provider: entries in the menu revert to the state in step 5 and mobile broadband does not connect
Expected behaviour:
Mobile broadband should do one of:
1. automatically reconnect in step 4, or
2. fully disconnect to revert to a clean state
Option 2 ensures that the machine does not automatically reconnect to a network connection that may cost money and gives the chance to connect to wi-fi instead. Alternatively a configuration option in the connection settings to allow option 1 or 2 (same as what MeeGo Harmattan does) would work.

Works for me. After resume from suspend, the device is disconnected, and shows up again as available to be clicked on to establish a new connection.
Is there anything you can add to this bug report to make it easier to reproduce this bug?
