Description Milan Denko 2017-08-09 12:24:27 UTC
ModemManager cant create a broadband connection.
On Fedora 26-64Bit, kernel 4.11.11.
It detect modem, but after initialising connection, it reset, and display no message.

We'll need *a bit more* information :)

Could you please gather NetworkManager and ModemManager debug logs while testing it? See
