After connecting a splitter to my network it no longer works. Why?

When using an ECB6200 you must use a splitter with the following specifications. 

  • MoCA 2.0
  • Bi-directional
  • 5-1675 Mhz 6kV
  • Coax ports are 3.5 dB

  • Pls recommend a 4-way splitter that meets these specs. I have looked on Amazon and have searched manufacturer sites (Antronix and BAMF). I have not found any that meet all the requirements. The 4-way splitters that I came across have 7 db loss

  • Guru,

    Here is the splitter that we here at Technical Support have purchased and use for our testing. It is not a four-way splitter but perhaps this manufacturer will have one that does.

  • Thanks for your response. You may have missed a key aspect in my ask. I want a recommendation on a 4-WAY SPLITTER that meets the specifications

  • We have never needed a 4-way splitter so we cannot recommend one. That's why we suggested the website above so you could contact them for better guidance as what to purchase.

  • I'm having all kinds of problems with Cox Communications. They changed my splitters and now my MoCa no longer works. Can you guys confirm the MoCA Channel and Frequency the ECB6200 transmits at?

    Cox has a similar product for their Arris Panoramic modem/router and it looks like it transmits at 1200MHz so it's probably ok to use the standard 5-1000MHz splitters from antronix but I suspect the ECB6200 transmits at a higher frequency.

  • gerrym,

    I would start with making sure the new splitters match what is recommended above. Unfortunately, here in technical support, we do not know the exact frequency that the ECB6200 transmits at. The best answer I was able to get was "Extended D-band: 1125 ~ 1675MHz" I hope this helps.

  • Ok. to replace the Actiontec Frontier Router with my own router, I have tried the following config:
    1. Wall coax outlet - (no splitter) Actiontec Bonded MoCA 2.0 Ethernet to Coax Adapter (ECB6200S02) cable In - TV side to the cable set top box. Then ethernet
    of the Actiontec Bonded MoCA 2.0 Ethernet to Coax Adapter (ECB6200S02) to WAN port of the router. No Joy for either connection.

    2. Wall coax outlet - to splitter to Actiontec Bonded MoCA 2.0 Ethernet to Coax Adapter (ECB6200S02) cable In. Other end of the splitter to the set top box for cable. Then ethernet of the Actiontec Bonded MoCA 2.0 Ethernet to Coax Adapter (ECB6200S02) to WAN port of the router. No Joy for either connection.

    Really need some help here.

  • Ron,

    Those should never be connected to the WAN port of your router. Only to one of the LAN ports.

  • I need some info. I only have 1 coax outlet in the room where my cable modem and separate router are. I only have Xfinity internet service and want to use 2 of these adapters to get internet service in another room that also has a coax outlet. How do I do this with only 1 coax outlet in the room where my modem and router are?

  • You will need to install a MoCA splitter to the wall outlet. That splitter will then connect to the modem and to the ECB adapter. If you need further assistance then please call the Actiontec Technical support department.

  • I think the above answers my question too but want to make sure. I have coax out of the wall to a Comcast Xfinity 1gig modem (bridge mode) that then connects to my Ausus router. Would I split at the wall with coax going to the ECB and then ethernet into my ASUS router?

  • Thanks. On the other end I plan on coax from wall to Moca Adapter and then Ethernet to a Ethernet switch to connect 3 devices. That will work?

  • Martin,
    Yes, you would put the MoCA splitter on the connection from the wall outlet then feed coax to the modem and ECB adapter. Then connect an Ethernet cable from the router to the ECB adapter.

  • Joe,
    Yes, you should be able to connect a switch to the ECB adapter for multiple Ethernet devices.

  • -3.5db is the per-port loss on a 2-way splitter. a three way will have 2 -7db ports and one -3.5db port. A 4-way will have 4 -7db ports. The only way to get more than a 2-port splitter without more than 3.5db loss is to buy an active splitter. however, an active splitter that supports MoCA would be more expensive than running ethernet.

    that being said, I have these units running through 8 port splitters with -14db ports and 150' coax and they work just fine.

  • Is there a splitter built into the ECB? In other words, if I hook up the coax from the wall to the ECB, then a coax from the ECB to the cable modem, would that work instead of using a separate splitter? I'm trying to avoid losses using unnecessary splitters.

  • Michael,
    If your unit is the ECB6200 then the answer is no. If the unit is an ECB6000 or ECB2500C there is a splitter built into the units with "Tv/STB Out" port only passing standard audio/video signal but not MoCA signal.

  • I bought 2 ECB6200 Moca Adapters. They're not working, the "receiving unit" doesn't get a coax light on. I did your troubleshooting tests of connected the two adapters via coax, then plugging ethernet into my router and the other into the device and it worked. So I looked behind the coax in my wall and found this splitter: https://www.amazon.com/Ideal-85-132-2-Way-Digital-Splitter/dp/B0025OVQPC Is this not compatible with moca?

  • Tim,
    You are correct. That splitter is not MoCA compatible. You need a splitter that supports between 1125 to 1675 Mhz. You may want to verify all splitters on your cable network and replace any that do not meet MoCA requirements.

  • I recently purchased an ECB6200 and WCB6200Q. I had no coax light on the ECB6200 so did the functionality test by connecting the two devices then running ethernet to a laptop. Lo and behold it worked. I have an amplifier at the POE into the house with ISP modem, one TV and connection to an outside poolhouse on that amplifier (all home runs). I'm not sure where I need to put a MoCA splitter to get the coax light to stay on when using the ECB6200.

  • Joyce,
    The splitters and amplifiers need to support MoCA signaling otherwise it will cause MoCA connection issues. The placement and requirements for splitters are dependent on your building cable setup. Typically you may need a MoCA splitter at the POE location and at the modem location.

  • I recently purchased the ECB6200KIT01 and have installed it; it is working but not sure if its working correctly. I have Spectrum Communications for my internet service provider (ISP) with 200 Mbps service and use an Arris TG1682G cable modem router combo that has MoCA capabilities but I only get approximately 7o Mbps of service at the MoCA adapter and I've had to use two adapters to get any kind of service, which I thought unusual with the Arris TG1682G's MoCA capabilities.

    My home has the main data cable coming in at the outside of the home and runs into a 4-way splitter that is MoCA approved and within tolerances (I only have internet and voice service; no cable television). From there my incoming data enters through the coax into my home in an upstairs office on a single coaxial cable. Before buying the ECB6200, the coax cable ran into the Arris TG1682 and WiFi and hard wired connections dispersed data from there. I have a data wire that runs from the modem router combo unit to an ethernet switch where I have two separate gaming systems connected where I receive approximately 200 Mbps of service on each when speed tested.

    I have since connected the ECB6200 MoCA adapters to my network and assumed I would reach speeds close to 200 Mbps as the other locations do when speed testing but I am no where close, even after turning off all other devices on my network. First, I connected a MoCA adapter at a television location downstairs so I could stream 4K movies but I did not get any sort of link with the router. I wonder if my provider is able to disable this function as when I sign into the routers settings, the MoCA box is checked but greyed out so that I can't change it. However, I decided to install a second unit at the modem and in doing so I was unsure of the installation technique as none of Actiontec's literature explains a connection with a single coax wire supplying the incoming and outgoing communication at a combination modem/router. I first installed the incoming coax from the wall into the data in connector and ran another wire from the TV/STB connector to the input on the back of the combination modem/router. I got the units to link and I speed tested the connection to find that my speed only increased 30 Mbps, not the approximated 300% increase that the box packaging suggested. Thinking that maybe I had installed the wiring incorrectly, I removed the wiring and added a splitter from the incoming coax in the wall and then wired the modem separately than the MoCA adapter, connecting the two with an ethernet cable. The results were the same, my connection speed had gone from around 35-40 Mbps to approximately 70 Mbps. As an additional measure, I hooked my Apple MBP to the ethernet port of the MoCA adapter and got the same same, around 70 Mbps.

    My questions that I am looking to get answered include:

    1. Should the Arris TG1682G be working with the Actiontec MoCA adapters on their own or should I have to have an adapter sitting in front of the router for operation?

    2. Should I be getting speeds as fast as the service I pay for that I am receiving on my gaming consoles that are hardwired into the modem?

    3. What suggestions can you make that will help me get the speeds that I am thinking I should be acquiring?

  • You need to connect the cable from the wall to the single port in the provided splitter, then one of the two splitter connectors to the router and the other to the data port on the adapter.

  • R Cook,
    1. If the Arris TG1682G has the MoCA ability enabled then you do not need an adapter at the modem location. If unable to enable MoCA on the modem then you will need an ECB6200 at the modem location as well as any other locations you want internet connectivity.
    2. The speeds can be dependent on your service. The ECB6200 MoCA adapters support MoCA and Ethernet speeds up to 1 GB.
    3. The only suggestion is to make sure that all splitters on the coax network support MoCA.
