Old thread :-) So, looking at the current set of LTE devices we're playing with, I didn't find one that supports setups like "2G/3G/4G allowed and 3G preferred". Devices supporting LTE allow to either select 4G-only or 'auto'. Some cases are even worse, like the LTE sierra modems which now don't even allow to select previously supported cases like "2G/3G allowed and 3G preferred". -- Aleksander _______________________________________________ networkmanager-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/networkmanager-list
