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’ll start by swapping out the co-ax cable when I get home as I have no splitters or amplifiers attached to it, then if it’s still occurring I’ll turn to isp and if it’s still happening I may reach back out, thank you for the responses.
