MoCA Setup

MisterVic Posts: 5

TLDR at bottom


As per the subject, I'm trying to setup my MoCA network.

I have read that TWC/Spectrum haven't supported MoCA since they have WHDVR or w/e setup they had before.

Knowing this, my modem/router is MoCA 2.0 capable and I would like to utilize it.


Following the "Data to post..." topic, here goes:


  1. Trying to setup MoCA but devices will not link/talk.
  2. 78640
  3. Single Home (~1400 sq ft)
  4. Internet (Spectrum doesn't tell me what speeds I'm paying for...)
  5. Ubee DDW36C Modem/Router Combo and GoCoax WF-803M 2.5 MoCA adapter
  6. Again, this varies. I get anywhere from 70/7mbps to 120/20mbps.


  1. Hardware Version3.22.1
    Software Version8.22.2121
  2. Currently online
  3. N/A
  4. Wired works great, but WiFi is where I get the issues...

  6. From the demarc the cable comes out of the ground to the ground block. I have a PoE MoCA filter on the source, which is then connected to a grounded Holland HFS-2 [5-2150mhz] splitter. One end of the splitter connects to my living room coax F jack. From the jack, it connects the supplied TW Ubee modem/router which is ethernet hardwired to various devices. The other end connects to my bedroom coax F jack. From the wall, it connects to my MoCA adapter which is ethernet hardwired to my PC.
  7. All cables are in basically pristine condition, as I'm a neat freak and store everything accordingly. No kinks, [noticable] wear, cracks, bent pins, or corrosion in any equipment. The ground block has some snails inside it, due to the recent rain. Other than that, nothing amiss.


TLDR: I wanna setup MoCA and, while my modem supports it, I need to know if TW/Spectrum need to enable something on their end for the devices to talk to each other.

    @MisterVic  You are absolutely correct that Spectrum will not provision MOCA operation into any of their 'rental' gateway units.  Apologies, I did not realize that your Ubee modem/router combination was provided by Spectrum or a holdover from the days of TWC.

    The MOCA blocking filter that you installed at the groundimg block isolates all of the MOCA devices connected to your in-home cabling from Spectrum's cable system.  There is nothing Spectrum does to enable or block MOCA within your home.  You indicate that you need MOCA to carry one ethernet port link between your living room and bedroom. 

    I'm guessing you want to do that because the router's WiFi won't talk from the LR to your computer in the BR.  You will have to set up the MOCA devices to work properly with each other.

    Well, that's almost entirely true.

    But if they disable MoCA capability in THEIR router/modem [which I only lease/rent], then that would be something I have no control over. This is what I'm trying to figure out.


    This is what's shown in the modem/router:

    Configue Information
    MoCA IP192.168.0.1
    Link Local Information
    MoCA Disabled

    This is what's shown in my MoCA adapter:

    SOC Version:MXL371x.1.15.7
    My MoCA Version:2.5
    Network MoCA Version:2.5
    IP Address:
    Link Status:Down
    Beacon Channel:1150
    Primary Channel:1175
    Secondary Channel:1300
    First Channel:1175
    Number of Channels:5

    I have made sure both lines from the splitter are active. I plugged the modem/router into the line in my bedroom and achieved online capability. I then plugged it into the living room and achieved online capability as well. This tells me both lines are receiving adequate signal. The MoCA adapter did not receive the channel information before the line was active, either. As soon as it was active, it picked up the info right away. I was hoping it was a configuration error on my part, but alas, MoCA is fairly plug-and-play.



    I do not have two adapters. I had hoped that by my modem/router having MoCA 2.0 capability, as shown on the Ubee page itself, I would be able to get my single adapter to talk to it. But by your statement, I assume TW/Spectrum refuse to enable MoCA in the modem/router [since it's out-of-scope] and I will be forced to buy a second adapter to get MoCA to work. While it is disheartening, thank you for that information.
