The Modem pulls almost 90mbit down when I force LTE mode, so the unit obviously has great signal and performance, however when set to "Auto" mode the useless things drops back to GSM and performs appallingly.

Is there something I'm missing, or a way to just disallow GSM mode and let it auto between 3G and LTE?
