Nighthawk M1 LTE Data Disconnecting/freezing

[dononeil]

I've had the Nighthawk M1 for about 4 months now, and until the last month or so I never had issues, but now it's continually just stopping passing LTE data, and it requires a band change for it to start working again. The unit is on ATT, and there are no issues on the ATT side of the connection (according to them). Anyone know what could be causing this, and how to fix it besides having to login every few hours to change the band?
