If there is too much potential difference between the two points, then it can cause issues for the equipment. If that is the case, then it may be possible to set up a ground loop with current flowing through the cable shield to the gocoax power supply then to the structure electrical earthing point and back through the earth to the outside box. The issue may be that the moca adapters are providing a connection from the coax shield to earth through their power supply. Post a picture of your open box and where the earthing cable goes, showing how far it runs, and the actual connect to the grounding rod, please.Īnd, yes, if your coax being used for moca goes outside, it should also be bonded to earth. That is to reduce the chance that lightning or applied current on the coax shield will enter the structure and cause a fire or equipment damage. The cable provider must connect their coax shield to earth before it enters the structure (house). When I look at my modem now, after several hours of uptime, I see NO uncorrectables (this was completely not the case before, many channels throwing uncorrectables after a few hours and most after several days) and power levels that are in line with recommended Docsis 3.1 levels, and my speeds are back up to normal again.
I also reset the Moca adapters, which I had been fiddling with, thinking they were the problem, and, just for yucks, gave them ip addresses in my network range, so I can check them if I need to. Since I am now only using coax for internet and Moca, I took every single cable (and the second splitter) off the first splitter, except for those cable modem and Moca adapater (and ordered some caps, which I will use when they come to cap off the open terminals). Thank you for the kick in the butt that I needed to go outside and look at the box (I always dread doing this), where I re-discovered a rats nest of cable connections and TWO five way splitters. Has anybody ever heard of such an issue (I have been reading and reading these threads, and not seeing it), or have a suggestion? I'm out of solutions, and am concluding that high speed internet and high speed moca don't play together well in my house.
In sum, I have great Moca to Moca performance, but an unstable and slow network, possibly because of interference with my Arris modem. I also tried using a Moca-rated splitter before the router, but that, if anything, made the router/modem performance worse.

My ISP download channels never use higher than 600 megahertz (I am attaching a partial picture), so it shouldn't theoretically overlap the Moca range, but I tried enabling only the high range on the GoCoax, to see if that helped things. Worse, the adapter seems to make the network unstable- there are many uncorrectable errors on the downstream channels, and the Arris modem periodically seems to drop the connection all together. Since installing the Moca adapters, I have been having some trouble with my network, primarily reduced speed- my system gives me 900/40 when I connect to directly to the Arris modem, or to the router without the moca adapters installed, but that speed drops to 600/40 and often less once I attach the GoCoax adapters. (Years ago I used Moca 1.0 adapters all over the house, and found them to be terrific for wifi deadspots.) I'm running an AiMesh system, with a node in the basement that gets poor wifi backhaul, and set up the GoCoax modems to improve speed at that node. Before I sell my GoCoax adapters, I thought I would check in here to see if folks have any advice.
