I have installed Ubuntu 16.04 on a Lenovo Thinkpad X1 Carbon (5th generation).
The 4G internal modem is showing as "Not Enabled" in the network manager. The model of the modem is: Sierra Wireless EM7455
The system recognises there is a modem:
$mmcli -L
Found 1 modems:
/org/freedesktop/ModemManager1/Modem/5 [Sierra] MBIM [1199:907B]
But when modem manager is started it shows the following errors:
ModemManager[15054]: <warn> [1490988196.927207] [main.c:101]
name_lost_cb(): Could not acquire the 'org.freedesktop.ModemManager1' service name
ModemManager[15054]: <debug> [1490988196.927263] [mm-base-manager.c:814]
set_property(): Stopping connection in object manager server
ModemManager[15054]: <info> [1490988196.928180] [main.c:187]
main(): ModemManager is shut down
I've had a Google about this issue and the best I could find was this thread on the Lenovo support forums.
However I have been unable to get the modem running with the information/ instructions on that thread.
Has anyone been able to get their mobile broadband running successfully on their X1 Thinkpad in Ubuntu 16.04?
mmcli -L
is not showing a modem is available although the device exists in the laptop?.
