The event log and the cable connections page help us to check and see if its a line issue. You can post a screensnip of them back here.

but you can check your line.

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.
If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.

Hello. Thanks for the reply.

I know there is a splitter on the coax cable before the modem/router as this was setup that way with Optimum's modem/router because I was having similar issues with it disconnecting. They wanted to add the splitter to resolve signal issues and it did indeed stop the internet from disconnecting with their modem/router. I have yet to remove the splitter to see how it performs without it on the CAX30.
