Can't reconnect 3G HSPA after disconnect ; log out and in fixes it

[Ishan A B Ambanwela]

I try to connect with connection named "Hutch" which is associated with a 3G dongle and HSPA service.

The first time it connects, but if it is disconnected and I try to reconnect it does not work.

nmcli con up id Hutch

to make this work I need to unplug and plug dongle again or logout and login again.This wos working on 12.04 and I doubt after update it to 12.04.1 this occured.

What is the exact model name of your dongle.

Please reboot, reproduce the failure, connect and then run "apport-collect 1099696" in a terminal to provide more information.

It's Huawei E303 this occurs with several dongles which I checked for.

If reboot it works very well.
It just occurs when I disconnect and try to reconnect.

not only on cli it fails with the gui.
