However, I much rather like the approach of simply grounding the diplexer! Thanks for the tip!
How did you actually measure the build-up? Even a multi-meter would probably drain the build-up that you're trying to measure?
Another great tip -- thank you! While I am not currently having speed troubles, I do very much appreciate the tip and will store it away for future use!
I actually figured out what was going on by using my Volt-Ohm-Milliampmeter's resistance-measuring function to check whether the the diplexer was already
grounded, by putting the other lead into the ground hole of the three-prong outlet right there - which instantly
knocked out the MoCA link.
Hmm - the VOM is measuring resistance by putting a small voltage across the two, so maybe something else - like new equipment on the telephone pole - is putting a much lower voltage across them, since that takes several days to build up.
At that point the solution was obvious - ground the diplexer to prevent a charge build-up. Problem solved.
An initial clue that I was dealing with static build-up was that whenever the link went down, it rendered inactive whichever ethernet jack on my main router was connected to the local Actiontec - if I switched the plugs around the problem would pop up again on the new jack.
By the way, I ultimately moved my cable modem down to my theater to give my Amazon Fire TV the benefit of being directly plugged into it, enabling me to get 1080p video from Amazon Prime. It shouldn't require that much speed, but I tried one Fire TV after another at the far end of the MoCA link, which never went above 720p ("HD") until I relocated the cable modem, using the MoCA link to instead serve internet to my PC upstairs. Now the Fire TV says "HD 1080p" once a video has been running for 30 - 45 seconds.
