Is this a valid way to connect a MoCA network?

    I have been having issues with my non-vox Mini boxes. I am in the process of re-evaluating my MoCA network connections. Is this a valid way of connecting a MoCA network?

    Yes. Just make sure network port of the MM1000 goes to the splitter and device port to the modem.

    And you should have a filter on the input to the splitter.

    By that he means a MoCA PoE filter on the input of the 6-way splitter. Adding a PoE filter will give a significant boost to all of the MoCA signals on your network.

    Can you be more specific as to the issues? Any error codes or specific problem symptoms? (Others have recently reported issues with Mini's connecting to their host DVRs, but the issues were resolved on the TiVo back-end or via a software update. See here.)


    As for the diagram, what @mdavej said. (Also, sometimes a MoCA filter can be required on a SDV tuning adapter or modem if they're seen to be unstable with an active MoCA network present, but that doesn't sound like you're symptoms.)

    I'd swap that 6-way out for a Zero-Gain MoCA Compatible Amplifier.

    What are the DOCSIS Signal Levels currently at your Cable Modem?

    You can usually get to the Cable Modem interface at:

    A worthwhile thing to consider if they're having issues with the cable signal at the modem, BOLT or Spectrum box ... but it wouldn't be of any more benefit to the Mini MoCA connection than ensuring that a "PoE" MoCA filter is installed on the splitter's input port.

    Here are my current levels on the CM500 cable modem - I do have a POE filter attached between the incoming cable and the 6 way splitter - I forgot that in the diagram. My main problem is the Mini intermittently loses connection with the Bolt. It comes right back but is driving my wife crazy (it’s the kitchen tv). Last night I tried renaming the DVR and setting the Mini back to default. I then went through the guided setup again. So far, so good but we haven’t been home much.

    Thanks again for all your suggestions and help! I have been reading through many posts and I thought that I would start by making sure the overall connections were correct.

    Those are great DOCSIS levels.

    What about your MoCA levels as reported by each device?

    There's a possibility that those splitters don't have a proper 'port isolation' spec and the devices can't get their MoCA signal to the other devices.

    Still going strong! I think the default reset fixed it. Thanks to everyone for their input for this matter. You guys are the best! Stay safe!
