Mobile broadband doesn't work in utopic (worked in trusty)

Bug Description

I realized today that I can no longer use the 3G adapter in my laptop since upgrading to utopic. Please find attached a screenshot of the nm-applet menu - you'll notice that my adapter appears to be listed twice ("Mobile Broadband (Dell DW5560)" and "Mobile Broadband ()").

Trying to enable mobile broadband and then clicking on "/234308387636800/context1" (what does that even mean?) results in a rather unhelpful error dialog (see the second screenshot).

Trying to enable mobile broadband and then clicking on "New Mobile Broadband connection..." results in nothing happening except for that menu entry becoming checked. But no internet.

I can't add a connection via "Edit Connections..." because no 3G devices are listed.

I have same problem with "Huawei E353" Mobile Broadband device.

I found this info from lsusb output:

"ID 12d1:14fe Huawei Technologies Co., Ltd."

There is no "Enable Mobile Broadband" on network applet, so I cannot connect to Mobile network.

When trying to do new network, I cannot see my Huawei E353 on list.

Chris, could you try and remove ofono? It's likely the inclusion of both ofono (from unity8 session stuff) and modemmanager is causing an issue.

Ah, removing ofono (and manually removing /var/lib/ofono afterwards) seems to do the trick

I had the same problem and proceeding as in comment #6 plus a reboot also helped me. I have a clean network menu without cryptic entries now and mobile broadband (currently Vivo in Brazil) works reliably.

Probably best solution would be letting the network-manager and ofono packages conflict or preventing ofono of being installed on a desktop )how will convergence work then?).

Why is this expired? Chris has answered Mathieu's question.
