Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

I've made another call and ISP will be sending a technician on 06/03 to investigate. ISP support saw no abnormal indications on their end at any point during this call, before or after performing the standard reboot and signal reset.
Have them look at the event logs and the correctables and un-correctables.
