Hi everyone,
I have a ZTE M195 USB modem. It works in live mode, but when I install Kubuntu on the disk, the mobile broadband tab is just greyed out in Network Manager. The modem has some proprietary drivers, but these could not be installed, because in 12.10 qt3-mt package is not available. Anyway the stick works flawlessly out of the box in live mode. I checked the groups in live mode . On the installed system I am member of the same groups. I guess permissions are not set correctly, or some package is not installed.
