Bug Description

Ubuntu 17.10 amd64 daily, encrypted home, German language

I tried adding a mobile connection (LTE), clicked trough the dialog but the connection will not show up in the list to select from.

lsusb:
Bus 002 Device 002: ID 12d1:15bb Huawei Technologies Co., Ltd.

syslog:
gnome-control-c[2348]: value "((NMSettingSerialParity) 110)" of type 'NMSettingSerialParity' is invalid or out of range for property 'parity' of type 'NMSettingSerialParity'

NetworkManager[955]: <info> [1502546435.3033] audit: op="connection-add-activate" pid=2348 uid=1000 result="fail" reason="gsm.username: property is empty"

gnome-control-c[2348]: Failed to add new connection: (7) gsm.username: property is empty

To reproduce:
go to "Settings" - "Network" - "Mobile Broadband", click on "Add new connection" in the "Network" field, click next to the Country list select "Austria", click next select "HoT" click next and again next then click Apply.

In the "Network" field no connection is added, clicking "Add new connection does not work until until i leave and reenter the "Network" section of "Settings".

workaround:
[Alt] + [F2]
nm-connection-editor
[Enter]

click "Add" select "Mobile Broadband" and click "Create..." follow the dialog at the end a "Editing" window appears, click "Save" in there. The connection now shows up in the Network list in the Mobile Broadband section of Network settings.

tried it again with daily image from today (9.Sept) still the same, followed the dialog selected My Country and my Network-Provider finished the dialog, no new connection, "Logs" shows:
"Failed to add new connection: (7) gsm.username: property is empty".

I just tried that here with a ZTE MF112 3G modem.

I plugged it in and Mobile Broadband appeared in the Network indicator dropdown. I then added the connection as you described.

When completing the wizard part the drop down is indeed blank, but dropping that down showed me my connection.

Would be nice to upstream to https://bugzilla.gnome.org/enter_bug.cgi?product=gnome-control-center by somebody having the issue

Additional: it seems the trick to making it appear in the dropdown is to switch the connection "ON" first.

This screencast shows what happens for me: https://youtu.be/oIXRjeqD4kc
