LB1120 gets stuck on 3G until power cycle

I'm having an issue on two separate modems where they will randomly drop down to 3G speeds and they will not go back up to 4G speeds.  One is an LB1120 and the other is an LB1121.  Both are on T-Mobile and have 5 bars of signal on 4G.  Doing a software reboot does not get them to reconnect, only doing a power cycle will get it back on 4G.  There must be some sort of software flaw causing this but I'm not sure how to get it fixed?

    I think several others on the board have responded similarly, including me.  It is a real PITA, but I already have a timer set to reboot both my LB1120 and LB2120s because they just stop working about every 14 hours and the only way to get them back is to reboot.
