The upstream power is high and may be intermittently fluctuating even higher out of spec.That will cause random disconnects and spontaneous re-booting of the modem. Are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured ?

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then putting them back together again, then perhaps it's best to book a tech visit to investigate and correct.

Sorry I couldn't respond to your help more quickly, I was out of town on vacation. After I returned home I noticed no lost connection for two days and it seems to work fine for now. The tech only has one splitter from the main line to the T.V. and Modem. I really thank you for the advice you've shared.
