[Bug 1723210] [NEW] mobile broadband connectie fail (timeout)

 

Public bug reported:

On Ubuntu 17.10 I cannot make a mobile broadband connection.
On my multiboot laptop with a Hewlett-Packard Gobi 2000 Wireless Modem I can successfully connect to T-Mobile broadband network when I use Ubuntu 17.04 (Gnome), but not with Ubuntu 17.10 (Artful Aardvark) with the latest patches applied.
The gobi-loader loads the firmware in both instances successfully ( the 3 ttyUSB ports are visible. I get a response on ttyUSB1  with an AT-command)

In the attached syslog you can see the connection times out.
