Internet keeps disconnecitng
Arris S33 sometimes it stays good for a couple of days and then it reboots*Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers

The signal stat values were good at that snapshot in time. Please post the modem's RF error log entries in their entirety (copy and paste all of the text) but redact the CM and the CMTS MAC addresses for your privacy or else the forum bot will not allow your post to be seen publicly.

Quite welcome ! I prefer not to recommend specific brands of equipment / hardware but that splitter is a good quality one. And yes. You can use a MoCA compliant splitter even if you don't yet have MoCA enabled.
Back to the issue at hand. So even though the signal status values looked good at that snapshot in time, the error log entries confirm that something is going on. Perhaps there is intermittent noise ingress into the line(s) / an upstream channel / return path impairment somewhere.
There are other signal stat values that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.
I'm going to escalate your issue to the Comcast corporate employees (The Digital Care Team) who are available to these boards. They will be able to poll the CMTS (Cable Modem Termination System) to check for any real-time degradation and / or error reports, see your node / cable plant, and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and check those upstream receive signal stats.
You should get a reply here in your topic. Good luck !

Hey there, @ROSSROSSROSS. Thank you for working with our community expert, @EG. We can dive into the signal like they suggested and provide assistance to get this intermittent connection issue resolved for you. If you could please send me a DM with your first and last name along with your full-service address, we can get started.
