I've been seeing this error for the past couple weeks but we've been plagued by connectivity issues for 2-3 months. I tried using the support chat, but it hasnt' been very helpful - just the usual restart the modem, run a test, etc. I have since upgraded to a mesh WIFI but the packetloss and speed issues persist on both WIFI and wired LAN.
What does this error indicate? It appears almost every day. Restarting the modem appears to help. Is there something I can check or does a tech have to come out? I haven't changed the cabling or anything since this issue arose.

I dont' have any way to monitor/log these, but whenever I check the modem I get power monitor values within the DOCSIS spec per this link:

In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test
If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed, and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
