Modem Firmware issue - causing no connectivity please help

Our modem is dropping connection, the logs are below. Can someone please help? MAybe we need to swap this modem out? We've had this issue since we moved to this location.

We rebooted the modem which caused the power failure notice today, but last time we did not and both times we were down for 5-10 minutes.
