How many MoCA POE filters do I need?

    Hi All,

    I have 1 Xfinity account with voice/cable/internet, but 2 separate coax feeds coming into my home on opposite sides of the house.

    One feed goes directly to my modem/router and the other feed goes directly to my TV splitter/booster because I have over 15 TV connections (the house came that way).

    I am now using powerline to my Tivo Roamio (from my modem/router) and 1 Tivo Mini, and then use MoCA to feed 2 other Tivo Minis.

    I assume I'm using the ethernet on the Roamio as IN and then the coax (MoCA) as an OUT to the 2 Minis ?????

    Anyway, I currently have no MoCA POE filter, but thinking I need one (or two).

    That's my question. Do I need a MoCA POE filter on both feeds?

    THANKS.

    Since you've got Comcast, there's a chance you're already using MoCA from their Router. Or could be.

    It would probably be a good idea to document your 'baseline' signal levels. Network Diagnostics in the TiVo's can provide MoCA Signal Levels. Both the TiVo and the Router have the Signal Levels available from Comcast.

    At a minimum, you should have a single POE Filter at (apparently) the input to the 2-way splitter where the 2 coax meet at the input to the house. Possibly, depending on which Comcast Router you have and whether you use it's built-in MoCA, you could have a POE Filter at the input to it. I can't see a need for any others.

    A POE Filter can increase the MoCA Signal Levels throughout the coax 'plant'.

    The inputs do no meet, I have 2 separate runs from the Comcast box into my house. Thanks for your thoughts, I will see if my Netgear AC1900 has a built in MoCA filter and check the signal levels.

    The Netgear won't have MoCA, but your Modem will have DOCSIS Signal Level info in it. What model is your Modem?

    You seem to have your TiVo configured as the MoCA Bridge?

    Is there a splitter at the Comcast Tap where your 2 runs emanate from or 2 separate runs off the Tap?

    Then the modem feed should have no MoCA signals present and so wouldn’t require a “PoE” MoCA filter.

    So, you’d require just one “PoE” MoCA filter installed on the TV feed, optimally on the input of the first split encountered by your signal — though, in your case, the optimal location would *seem* to be built-in to the amplifier.

    What’s the brand/model number of your amp? (And how are you achieving over 15 drops from the single amp?)

    Do you know to which amp outputs your DVR and MoCA-networked Minis are connected?

    Any reason you aren’t using MoCA for all your Minis?

    p.s. The amp may not be needed if you’re only using TiVos, and have just the one DVR, as the raw cable signal is only needed at the DVR.

    WOW !!!! You guys are GREAT ... but honestly I'm lost. Here's a picture of my connections. Like I said, everything is working, the only reason I didn't put the 3rd Tivo Mini on MoCA is because the coax connector is on the wrong wall where the TV hangs. The other TVs that don't have Tivo Mini's simply have Comcast DTAs.

    I know the amp is by Blonder Tongue, it was here when we bought the house and takes the direct Comcast feed. Then that single connection (output from the Blonder Tongue) goes to a block to splits the signal (it up in the attic). I think it has 16 connectors and all the TVs are connected to the block. That's how I think the MoCA is networked. But, I have the Powerline adapter connected to the Roamio also (via ethernet) and that's how I think I'm getting internet to it & the 2 MoCA Minis. So you can see I don't really know what I'm doing, but hey, everything seems to work. I just want to know if I need a filter :)

    Netgear AC1900 Telephony Modem/Router.
    No splitter from Comcast, 2 separate runs.

    The C7000?
    Netgear AC1900 is too generic...

    This one?:

    Just one between "Comcast" and the "Apartment splitter (15 Coax/TV)" shown on your diagram.

    As previously stated...
    To be more specific would require knowing the amplifier model number, to review its specs, as previously asked...
    But given this more recent description...
    ... your optimal “PoE” MoCA filter location would be between the single-in/single-out amp, on the input of the “block”(?), but then this description doesn’t match your diagram. (If the amplifier and “block” are distinct devices, it should be reflected in the diagram; and more detail on the “block” would be worthwhile, to possibly further optimize your MoCA network.)

    ‘gist: A “PoE” MoCA filter on the incoming TV line upstream of the amp will secure your MoCA network, but you’ll need to provide more details on the amp and “block” to determine the optimal filter location, to net the best possible MoCA performance.

    I've updated the diagram to show the Blonder Tongue and the Channel Vision splitter.

    Your “PoE” MoCA filter should be installed on the input of your 16-port Channel Vision splitter, the first split encountered by the incoming signal on the TV feed.

    So, a question... you have a direct cable run to your modem location, but is there a separate coax run to that same location/room from your 16-port splitter?

    I have 2 separate runs directly from Comcast to different locations. Each run is connected to the Comcast (green) box in my neighbor's yard. One comes into the attic for the AMP/Splitter and the other comes into the wall where I have my office directly to my Netgear Modem/Router.

    To answer your question directly, there are 2 coax connectors in my office. One directly from Comcast and just feeds the Netgear Modem/Router (through an exterior wall), the other coax connector comes from the 16-Splitter and it's where I have my Tivo Mini using MoCA to watch TV.

    FYI ... Comcast said I could only have 2 runs with 1 account. Not that I wanted more.

    Yeap, that's the one. It comes after the AMP and every coax connection in my home is on it. Also, some of those 16 connections are then split ... I have 22 coax connections in all. The guy I bought the house from was a bookie. He used to have as many as 8 TVs on a wall and TVs in every bathroom. So yeap, I have a lot of TV connections. When I moved in he also had Direct TV and Dish Network. It's a networking nightmare.

    Are the coax wall outlets near each other? Just curious why you’re not using a standalone MoCA adapter at the modem/router location, connected via coax to the 16-port splitter, as your main MoCA bridge, rather than the sub-optimal Powerline/MoCA bridge via the DVR.

    A budget WCB3000N ($26 via Amazon) would provide Ethernet ports for both the MoCA/Ethernet bridging and the Mini, and match the MoCA spec of your Roamio DVR and Minis (assuming they’re A92/A93 versions).


    edit: p.s. With a standalone adapter as your main MoCA bridge and the DVR reconfigured as only a MoCA client, you can then leverage the DVR’s otherwise-unused Ethernet port to extend wired networking to other Ethernet devices co-located with the DVR. (see here)
