CM700 constant reboot "No ranging Response Received-T3 Time out"?

Hey everyone, 

This has been driving me nuts the past few months and I have been going back and forth with Optimum, who, of course, blame the equipment.

Lately the modem has been resetting itself. Today it happened 3 times in the hour, which is finally prompting me to investigate it.

Posted below are the modem logs. Hopefully the community can help me out with a possible solution.

Additionally - Im using this along with a nighthawk AC1750 router 

Thank you for all of your help in advance!
