I tried setting up a Roamio and Mini with two Tivo Bridges but can not get the Roamio to connect. I have the coax coming from the wall with my splitter, then one end of the split coax into the modem the other into the bridge. I have the main Ethernet cable coming from the main Ethernet port on the router into the modem and then I have the other Ethernet cable going from the bridge to a port on my router. In my living room I have a cable coax coming from the wall into the splitter with one end going into the Tivo bridge and the other end into the roamio coax connection, and I have the Ethernet coming from the Tivo bridge into the Ethernet port on the roamio. All lights are on. When I try to connect via Ethernet I get an error saying that my router has some TCP ports fail (NO2) and the roamio won't connect. If I try to assign the roamio a static address and I'm not sure I did that right, the instructions said to make sure it wasn't within the range of the router's assigned addresses so I picked one at random and inputted the gateway, subnet mask,etc, I get router not found (NO7). I called Tivo and they were no help. I called Linksys (it's a 1200ac) and they explained to me how to open the ports on my router, which I did, but it did not help. I am at a loss.

It sounds like you have the connections in each room correct, but what remains unknown is how these two rooms connect to each other. Do you know where the coax runs to these rooms come together, and can you report whether they come together at a splitter or amplifier, and what the model # for the device is? And do you have a PoE MoCA filter in place? (More on PoE MoCA filter here: Why? & How?)

If you live in a "multi-dwelling building," you may want to review > this post <, highlighting proper connectivity in such a situation.

Also, have you tried connecting a laptop or PC with an Ethernet port to the remote MoCA adapter to see if they could make a successful network connection through to the router and Internet?
I don't know how they connect. They both come in from the wall from outside, so I imagine there is some kind of junction box where all the coax cables come into the house. They are not connected internally, each room of the house has a coax cable coming in for a television signal. Also I do not have a POE filter, but I ordered one the day before yesterday and it should be here today -Amazon Prime :) - It's a one story house, about 1500 sq ft, not very large, so I don't think there are any long cable runs. I was just wondering if maybe it was the router? Oh by the way, thanks for the info.

Good point re: Mini, I'd forgotten that was in the mix.

Have you tried connecting the Mini via coax/MoCA, even without the Roamio being able to connect to your MoCA network?

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.

Additionally, you can verify the bridging MoCA adapter is functioning and the Mini capable of connecting via MoCA by directly connecting the Mini to the bridging MoCA adapter's coax in port, and then configuring the Mini for a MoCA connection ("Connect using MoCA").

These confirmation tests can be useful in eliminating possible concerns with the components involved, and may help direct your troubleshooting focus.

Hi,
I am just addressing your failed attempt to set a "reserved" IP for your Tivos. There is a difference between setting a fixed/static/reserved IP on the device vs setting it on the router. Without getting into a long explanation it is usually best to do this on the router because in most cases the router controls the IP's. In about 2 minutes of googling "reserved IP on Linksys AC1200", I discovered that on that router, you must "reserve" the IP from something within the DHCP range not outside of it. Linksys Official Support - How to configure DHCP Reservation using your Linksys Smart Wi-Fi Account which is probably why you got the "router not found."
Normally, you should not have to mess with any of the port settings on the router either.
I would try using the normal DHCP settings on the Roamio and reset the router if necessary to start over.
As far as sorting the MoCA issue, first thing is to let us know which Roamio you are using to determine if it has MoCA builtin....important information.
Thanks, I just googled setting a static IP, so you gave me more info. Much appreciated. It's the Tivo Roamio (basic 4 tuner), not any of the newer ones with MoCA built in. I really appreciate the help. With all the info on this site I may have this thing up and running today :)

Thanks. The splitters are good, they came directly from Tivo and say "Tivo MoCA splitter" on them. I There's a cable box in my backyard that all the cables come from, so I will trace it into the house. Thanks.

Thanks, but that's how I initially did it. When that didn't work, I restored my router to factory settings so all other devices were not stored in it and tried to use DHCP again and it didn't work. That's when I tried (and did it wrong obviously) to configure a Static IP. It would not connect via ethernet (the only option with the first Roamio) so I tried to connect wirelessly. It prompted me to unplug my ethernet cable and when I did that, I still got router not found. I then went to the home page and used the help menu to restart the Roamio from the beginning setup process and when I got to select internet, I chose wireless (since the ethernet cable was unplugged) and it connected. I then plugged the ethernet cable in and it was connected via ethernet so I went into my other room to connect the mini. When I was going through the setup process, NO7 router not found prompt popped up. Went back into the livingroom and the Roamio had lost it's connection. That's when I decided to join this forum. Thanks.

Sorry, I don't understand the question? Not sure what a random IP is, but I disconnected everything now and just have the roamio running over wireless. I looked at my router map and it has the roamio's IP on there. For future reference, if I do have to give it a static IP, do I use the IP that the router has assigned it wirelessly or do I use another one. Thanks

Thanks, I've been at work. 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. So if I understand right, where I have the main bridge by the router, connect the mini into the bridge to the port. How do I connect the two MoCA bridges to test them? What's the setup, and how do I do it? The Tivo bridge isn't like the Actionec so I only have an input for the Coax. How do I go coax to coax when they are both male ends?

Where do you stand on testing the MoCA adapters using a direct coax cable connection between them? Or connecting a Mini directly to the bridging MoCA adapter's coax port and configuring the Mini for MoCA? (The Mini will complain when it can't find a compatible host DVR to which to connect, but it should still prove MoCA network connectivity.)

When you've successfully connected the MoCA adapter or Mini as MoCA clients, you should then be able to move them to their intended location and see whether the MoCA connectivity remains. If not, then you'll need to do the coax line tracing previously discussed.
Looking at the setup, I don't know how to connect the mini directly to the Tivo bridge either. The Tivo Bridge's only output is an Ethernet cable, should I use that instead of the coax? The coax end of the bridge is only an input.

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

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.

They *should* be good, but don't exclude the possibility they're faulty if/when everything else has been ruled-out.
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?

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.

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?
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.
