I installed xenial (xubuntu) on my Lenovo x220 and all works well. I also setup my broadband network interface to use T-Mobile and connection works. But after reboot or hibernate I ever have to restart network-manager service to see the broadband interfaces in nm-applet.
What have I to configure to see my broadband device directly after reboot or resume from hibernate?
pkexec sudo systemctl restart network-manager.service
. Sometimes I also have some WiFi problems if I reboot with it (soft)disabled. Maybe someone can throw some more light into this...nmcli radio wwan off && nmcli radio wwan on
and other nmcli commands which seems to be a cleaner solution...
