** Description changed:
Hi,
- I use Ubuntu 15.10.
- If I Start Ubuntu from power-off, then I can enter the PIN-code for the
SIM-card, and I also get prompted for my password (to make changes to the
mobile broadband device). The 4G-USB-modem gets green light for establishing an
4G (or 3G) connection, but it is impossible to connect to the 4G-internet from
the drop down menu of network manager at this stage; I get an error message. (I
have set up this 4G-internet-connention with help from the network-manager
wizard, using defaults, except turning off roaming and setting allow all users
to connect.)
- However, if I choose to reboot without power-off, the green light on the
USB-modem stays on during the reboot (keeps 4G-connected I presume), then it is
possible to connect to internet from the drop down menu, most of the time. One
time I also had to deactivate-activate mobile broadband from the drop down menu
for internet connection to be established.
+ I use Ubuntu 15.10, I have done a fresh install formerly using 14.04 on
+ the same hardware setup.
+
+ If I boot Ubuntu from power-off, then I must sometimes enter the PIN-
+ code for the mobile broadband SIM-card, I also get prompted for my
+ password (to make changes to the mobile broadband device); however, most
+ of the time only my password is needed, and the saved PIN-code is used.
+
+ After entering my password the 4G-USB-modem gets green light for establishing
an 4G (or 3G) connection, but it is impossible to connect to the 4G-internet
from the desktop drop down menu of network manager at this stage; I get an
error message.

It is also not possible to edit the connections of the mobile broadband
in the network manager applet (gets an error message). Editing the wifi-
connection works just fine.
