Public bug reported:
Most of the times I can connect to broadband mobile network via my 3G
usb modem fine (except issue #1071853), but at random times the
following happen:
- I am initially disconnected (e.g. because I had been using wifi), and "Enable
Mobile Broadband" in the menu is checked
- I click on the mobile broadband network I want to connect to which is in the
list on the upper part of the menu
- IMMEDIATELY a toast/popup/whatever-it's-called notification appears with the
icon of the mobile broadband (antenna + signal strength bars) and the message
"Disconnected"
- When this happens once, then I can retry 100 times and it will systematically
fail in the exact same way
- unplugging and replugging the modem, waiting about half a minute and
retrying will systematically fix the issue.
This is not after issue 1071853 happening (otherwise, the MB network
wouldn't even be in the menu to click on in the first place), and this
is not when issue #1019395 is going on (I can roll over the "more
networks" submenu and see the submenu non-empty)
