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.
