I use USB Modem (Mobile Broadband) to connect to the internet. Prior to Ubuntu 16.04, there used to be a connection setting where you can set a Network-Type (aka
gsm.network-type property) through either the GUI Editor or the command-line (you can see the
gsm.network-type property there).
However, this setting seems to have been removed since 16.04, its no longer visible in the GUI or configurable in the CLI. My problem is that the mobile broadband that I use works well only in "3G Only" (aka UMTS) mode, otherwise there are frequent disconnections in the default auto mode. So, how do I enable that setting in this new version of
network-manager? Is there any workaround to it?
