Constant disconnects in 89147

Have a technician coming out, but scared they won't find anything wrong.  Nothing changed on my end, suspected it was the router, but have tried 3 different routers AND have directed connected a wired computer to cable modem and it still disconnected in the middle on the night.  It's just a quick hiccup but just enough to knock off streaming/video/games.

Here's my cable modem's log with this repeating message

    Nothing else in the logs? That by itself doesn't look like a problem. Post signals and especially look for a growing number of uncorrected codewords. If the number of uncorrecteds is consistently increasing you have a problem.

        I would explore the reasons for all of those uncorrectables. If your uncorrectables are constantly increasing that's a problem on the downstream. Every now and then you might see a momentary burst of uncorrectables due to maintenance on the line or whatever. But if you're getting uncorrectables on a regular basis it's going to cause connection problems because that represents lost packets and lost data. For comparison I've had a total of about 20 uncorrectables in the past 2 months. You are showing over 100,000 since whenever your modem was last rebooted.
