Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.

All of that has been done. I’m trying to determine what the critical log code 3 means and can’t find the info anywhere.

Take a screen snip of the full event logs as well as the cable connections page and post them back here. You'll have to do more than 1 post (use the "choose file" method or we can't see it for several days)
