So clearly you're near a border, and you can't register with T-Mobile or AT&T because your SIM is a Bell one right? It's quite odd that you don't see Bell HSPA networks. Can you see them with the 313u which should support the same UMTS bands? Also, try forcing the modem to LTE All with AT!BAND and see what it comes up with. Also, does any of this band stuff here work? Next, are any of the ports QMI or QCDM? Try running libqcdm/test/test-qcdm --port /dev/ttyUSBx a few times on each port and see if you get any responses. Windows/Cradlepoint may well be using CnS or QMI on the device which we can't because we don't have the specs for that protocol. _______________________________________________ networkmanager-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/networkmanager-list
