sagemcom fast 5688w internet going out or losing connection

I have the Sagemcom and am also having way too many internet drops. When mine drops, the app always seems to have the LTE CQI as zero. Doing a reboot either from the app or with the power button almost always restores the connection. The drops happen at all hours of the day or night, so it doesn't seem like a congestion problem. I am using my own router connected by ethernet and have wifi turned off on the sagemcom. Will try doing a factory reset and see if it helps.
