CM Status issues and spotty connectivity

I broke down and tried tech support via chat.  The person helping me said they can see that my signal has been unstable since 10/1.  He provisioned my modem and we restarted everything again.  He said the signal appears stable now, but my modem is still showing the same issues.  What do I believe?  

Same two events all day today.

My previous post showing the modem status and event logs was taken with a MOCA splitter inline.  That may be why ch. 48 had -11dBmV.  Still getting the same events today.  I had to use my phone as a hotspot to get work done today.  The signal was very unstable.

Online search tells me my modem is having trouble staying bonded.  The code 16 and 24 events just keep alternating.  I am currently waiting for the technician to show up, but a representative from their advanced network support called me to tell me that the signal appears fine on their end, and asked if my internet is working.  I said no, and he asked if I was measuring the performance over wireless or connected directly to the modem.  I told him our modem is still reporting issues and that our connectivity has been really bad.  He gave up really quickly and said the tech should be here soon.  

Weird how your ch 48 is locked but listed as other.  Tech should be able to help and since you have your own equip that's pretty much your only option.  Seems like some sort of wiring issue somewhere or that MoCA is bad.

Channel 48 / other (no matter what the local system channel label number is) it's arbitrary on any local system.  It is the DOCSIS 3.1 / OFDM downstream channel for their gigabit speed tier and it is a known firmware issue that some makes and models of modems's measuring mechanisms incorrectly read the signal stats and the bit errors.

Thanks for the responses.  Regardless of whether or not I have the MOCA splitter attached, ch 48 is always out of whack, it just went lower in power with the splitter.  EG you are saying ch 48 isn't something I should be concerned about, then I'm good with that.  The error logs still have repeating 24/16 codes every minute or two.  All of that may be benign, but our service has been terrible lately, and the last two days have been the worst.

The visiting technician checked our outside connection first.  He replaced the MOCA poe filter that is between the source coax and our home. I did not know they used these (it makes perfect sense now though) so I guess I don't need to install one inside my home when I set up our MOCA.  Checking the signal strength made him go and check the node a few houses down.  He said the box in the ground was filled with water, the connection adapter to our line was swollen, and the ends of the cables were hard from the repetitive heat cycling and water intrusion.  The connection piece was replaced and some cable ends cut and recapped with new adapters.  He monitored the signal strength and noticed enough of a drop to suggest that might be our issue.  He came inside and checked our connections, but nothing exciting.  He put in a request to have the underground line replaced due to the signal drop he noticed.  Not sure what we can do about the water, maybe talk to our neighbors.  

School and work is now in session here, and it seems to be behaving so far.  The new underground cable should be dropped today or early next week.  Hopefully that will restore everything back to normal.

I was going to install our old modem to see if we get the same issues.  The new one is only 2 months old, and of course out of the return period, but I'll bite the bullet and get another one if it helps.  Can't have the wife telling me the internet is not working.
