Here's a really weird one for you guys
I bought 2 goCoax adapters late last year. I couldn't get them to connect no matter what I tired. When I hooked them up as shown in the instructions only the first and last LEDs lit up. The middle one didn't. I tested them by hooking them together and all 3 LED's on each adapter lit up.
I just left them hooked up and kept meaning to contact support or post here but I'd forget about them when something else came up. Well, this morning they started working. I have no idea what happened as I haven't changed or done anything to my network. I'm thankful they're now working. However, I'd like to buy some more adapters and I'm wondering if anyone has any idea what happened so I don't run into issues with the new ones.
Here's the network topology (excuse the MS Paint drawing)

The coaxial cables in my house are all RG59. Each one is a single line from the electrical room in the basement to the room. They all work as I have a TV in each room. The cable mode is a Hitron CODA-4582 that is on its own separate cable line that's not connected to any of the cable in my house. The cable company put in an Antronix MVRA902B splitter last year which says it's MOCA compatible. https://www.antronix.com/pdf/DS-1152-AR-MVRA902B.pdf
As you can see I have an Eero Pro connected to the cable modem and a basic gigabit switch connected to the Eero. Everything else is connected by wifi through several Eeros scattered throughout my house.
That's the thing, nothing was added or taken off the network during those 9 months; either on the coax network or the "internet" network (excluding my phone when I come and go from the house). I haven't reset anything either (although some devices may have reset themselves due to an update or something without my knowledge). I have TVs connected to each coax outlet and haven't experienced any issues with any of them so I assume the cable runs are all OK. I used a coax continuity tester (it said it specifically tested for data continuity as TV and voice are apparently a bit more forgiving on continuity) for each run and they all came back OK.i guess they needed a long warmup....LOL. Maybe the question should be what was taken off the coax network ?
It is also possible there was a poor connection in the cable run - or possibly water that finally resolved itself.
Look for any wire whiskers from the shield or little foil next to the core insulation around the conductor in the coax terminations.
Thanks, degrub.minimize the number of splitters and unused ports from the entry until the DocCis modem/xfinity box even if you have to replace one.
The DocCis modem has to have direct link outside to the ISP on the cable.
So that may mean the 3way splitter at the inlet to the DocCis modem, the go Coax modem, and the Xfinity box (if it needs coax) logically. If your cables don'twork that way you may need to use splitter at another spot. The POE filter is used to block the moca signal from the wan side of the DocCis and Xfinity modems.
i would replace the first splitter in your "revised" with a barrel connector.
Huh, I wonder if this was my problem. I have 10 Cisco Nextbox set top boxes in my house that were supplied by my cable provider. One of them is also a PVR. I wonder if I was experiencing the same issue as you. How did you determine the STB was causing syncing interference? Did disconnecting the STB allow the adapters to sync? Did you reconnect the STB they synced and if so do you have any issues?Thanks, degrub.
The problem was traced to the XFinity X1 set top box also being a Moca device (relabled DVR Anywhere). It highjacked the synch operation of the two goCoax devices. I'll have much more to say on this when another POE device arrives in the mail.
Well I know all my STBs are MoCA devices since my cable provider now offers cloud PVR storage and streaming to any STB in the house. You don't need a stand alone PVR any more. How are you isolating the X1 box with PoE devices? I'm not clear on what a power over ethernet device has to do with MoCA.There were two Eureka moments. The first was that the Xfinity box, which was I thought only a sample streamer of content. was also a Moca device. The second was that a synch of GoCoax devices could be achieved if the connection to the Xfinity device was momentarily interrupted. I had no issues afterwards, but am awaiting receipt of a second POE device to isolate the X1 box.
Of course, your situation is more complicated...

Just so I'm clear were you able to use the cable box once the MoCA network was up and running? All of my STBs are working normally even with my MoCA network operating at full speed.
9 / 10 of my STBs are "simple cable boxes" too without any built in DVR. However, like many stand alone cable boxes, they're able to receive content that you have recorded and saved in the cloud. That way any TV in your house that has a cable box attached to it can receive and control a recorded show. You probably have the functionality built into yours but you may not have subscribed to that option so it's not enabled.It's just a simple cable box with no DVR capability.
< .. were you able to use the cable box once the MoCA network was up and running? > Yes
I didn't mention anything about power over ethernet.
Right now, the MoCa network works if the X1 device is temporarily suspended to allow the 2 intended MoCA devices to synch and not be hijacked by the X1 device. Once synched, the cable box can be connected and used. I'll try to isolate it once a second POE arrives August 1.
POE is Point of Entry
I've only ever heard POE in reference to Power Over Ethernet. I've never heard of a MoCA filter being described solely as a POE filter.a POE filter blocks the MOCA signal.
