How do I connect the two MoCA bridges to test them?
Per above...
Note that you can verify that your MoCA adapters are working, eliminating concerns with connecting coax lines & equipment, by connecting them directly using a single coax cable between their coax input ports. You'd disconnect the "bridging" MoCA adapter's coax port from your main coax lines for the test, but its Ethernet port would remain connected to a LAN port on your router. And you'd need a laptop or some other device with an Ethernet port connected to the "client" MoCA adapter to verify connectivity through the adapters.
  • A coax cable between the adapters;
  • the bridging MoCA adapter connected via Ethernet to a LAN port on your router;
  • and some Ethernet-capable test device connected to the Ethernet port of the client MoCA adapter (ideally a laptop or PC with an Ethernet port).
You'd then verify the laptop has wired connectivity via the MoCA adapters (making sure to disable any wireless adapter on the laptop/PC), and optionally test the throughput across the MoCA segment.

I got the POE filter and it is at the junction right before the cable comes into the house so it is at the POE on the outside of the house.
When you say "the cable" I'm hearing that this is the only line coming into the house from the cable provider. That's good, as the MoCA filter located there will prevent your MoCA signals from traversing out onto your provider's premise and possibly into your neighbor's homes.

The preferred location for the PoE MoCA filter is on the input to the splitter* (coax distribution device) to which that line coming from your cable provider connects, to improve the performance of your MoCA network by minimizing any unnecessary travel of the MoCA signal. And sometimes the PoE MoCA filter can be placed a bit deeper in the coax network if the MoCA network's scope allows, further improving performance by limiting the MoCA network to just the coax runs where it's needed. (Another poster just linked a diagram with just this sort of configuration, here.)

* I'm still interested to learn the model number of that initial splitter, as it's the most critical component in your coax network, aside from the MoCA bridge.

The splitters are good, they came directly from Tivo and say "Tivo MoCA splitter" on them.
They *should* be good, but don't exclude the possibility they're faulty if/when everything else has been ruled-out.

I tested the MoCA network the way you suggested and it worked, so there's no problem there. Disconnected Wifi on my desktop and ran it through the two bridges connected via Ethernet to the router. Worked like a charm. Couldn't test the mini though because my monitor that I would have to use is a VGA monitor and the mini can not take an input other than HDMI, USB, and it also has small ports for audio and visual like that says component, don't know what that is. But I'm pretty sure the adapters are good, so I'm going to try to run the setup again with the POE installed. Also, the splitters are "Starburs Technologies MoCA 2.0 2-way splitter

I would also like to know the sequence in which to power down the equipment and power back up that is most effective. I've been powering down the router, then the bridge, then the modem and powering back up in the opposite direction. Is that an effective way of doing it?

Power-up should be (where applicable):
  1. Modem
  2. Router
  3. Network Switches
  4. MoCA bridge (or TiVo DVR w/ MoCA bridge)
  5. MoCA adapters
  6. Other TiVo devices
Power-down could be in the opposite order, but is of less importance.

A quick note re: your splitters; nothing authoritative, just wanted to provide a data point to buttress the "careful with assumptions" case.

See this thread: Moca diconnects and splitters are not all equal

If you have any splitters rated even for 5-1002 MHz, you may give them a try in place of the Starbursts -- though not yet having identified your distribution point component, I'm not sure you're yet at the "upgrade all splitters" phase.

If you can see where the cable enters the house, can you then go inside and find where that cable comes in and trace the cable to where it splits off to the different runs to your rooms?
There is a main splitter outside that splits the cable coax and the internet coax. From the cable coax there is a four way splitter that splits into the different rooms with cable. I put the POE filter before the cable and internet coax, so it's before all the cables splitting into the rooms.

Just retried it with the Roamio, same NO2 problem. Ports need to be opened on the router
Don't assume anything needs to change on the router. That's very likely just the Roamio unable to establish a network connection with the router owing to the MoCA adapter not making a connection back to the bridging MoCA adapter. Right?

Do you have any other Ethernet-capable device that you could connect to the client MoCA adapter in order to test its MoCA connection?

Alternatively, can the Mini establish a MoCA connection connected to the coax line in place of the Roamio's MoCA adapter?

Given that you're establishing your MoCA network at your cable modem (and router) location, the PoE MoCA filter would need to be on the input of that initial 2-way splitter, just as you say you've done, to ensure the MoCA signals can travel from the modem location up and through that 2-way over to your 4-way splitter and its downstream locations.

There is a main splitter outside that splits the cable coax and the internet coax. From the cable coax there is a four way splitter that splits into the different rooms with cable.
Oh, ok, good. Can you report the model #s for those splitters outside, and their supported frequencies printed on their labels? (e.g. "5-1002 MHz")

Aside from some unexpected cabling issue (bad cable or connectors, coax run not actually connected), the specs on any/all splitters need to be reviewed, possibly upgrading to known good MoCA-compatible versions. (Verizon or Holland branded MoCA 2.0-rated models are recommended.)

Ok I disconnected the Ethernet from the Roamio input and connected it to a laptop and the laptop could not connect, so it's not the Roamio

the splitters are 5-1000 MHz two way and three way isolation splitters, so that may be the problem. Also I don't think this is it, but on one of the splitters, the main one that splits cable and internet there is some kind of adapter on it that looks sort of like the POE I bought, (meaning its round and has a male and female end). There's also a sticker on it that I could not totally read because it's wrapped around where it is attached to the house. But the part I can see says, "Do not Remo...) which I assume is "Do not Remove" but underneath the words "For..." but I can't see what's behind that. I assume that is some kind of adapter cable companies use to route internet through the cable into the home, but I don't know for sure.

Is there any chance you could take a picture of those splitters and that "Do not Remo..." device, and post back?

Short of that, I'm leaning very heavily towards that "Do not Remo..." device being a whole home filter (i.e. MoCA filter), and am very curious exactly where it is sitting in your coax hierarchy?

Is it somewhere between that initial 2-way splitter and the 4-way?

p.s. That cylindrical component likely has printing that says "Do not remove... Required for Multi-room DVR" or something similar. Do this... REMOVE IT ... but keeping your PoE MoCA filter in place on the input to the initial 2-way splitter. (Later, if this proves to be a breakthrough, if you're still inside the return window for your new MoCA filter, you could move this newfound old MoCA filter to where your new filter is properly installed for your setup, the input to the initial 2-way, and return your new filter.)
