3.2 MOCA


Q. What is MOCA Networking?

A. MOCA Networking is designed to use your existing coax cabling as the physical media in an ethernet network. MOCA Networking can coexist with video on coax.

In a typical FIOS installation, two MOCA channels are used.
•MOCA WAN carries the internet signal from the ONT to the router.
•MOCA LAN is used between the router and the STBs.

MOCA WAN and MOCA LAN operate on different frequencies above those used by TV.

Verizon uses the Actiontec MI424-WR and the Westell A90-9100EM routers which support both MOCA WAN and MOCA LAN.

It's possible to take advantage of this capability to extend your home network.
»Verizon Online FiOS FAQ »Can I get an ethernet connection in a room with only coax?

by More Fiber See Profile

Q. I have a Tivo, game console, PC, TV, etc. that needs an ethernet connection in a room that has only a coax connection. Is there some way I get a remote ethernet connection?

A. To do this, you need to install a MOCA LAN bridge. A MOCA LAN bridge converts ethernet over coax to/from ethernet over cat5.

A list of available MOCA bridges can be found here: »Verizon Online FiOS FAQ »What is a MOCA Bridge?





1) Using a simple MOCA LAN bridge (NIM-100, ECB2200, etc.)


    If you have an unused (working) coax jack:

      •Connect the MOCA bridge RF-IN jack to the coax jack.
      •Connect your ethernet device to the MOCA bridge ethernet jack.

      If you have a coax jack with an existing STB:

        •Disconnect the coax from the STB.
        •Connect the coax jack to a 1x2 splitter. Make sure the splitter is rated 1 GHz to pass all signals to the STB.
        •Connect one leg of the splitter to the MOCA bridge RF-IN jack.
        •Connect the other leg of the splitter to the STB.
        •Connect your ethernet device to the MOCA bridge ethernet jack.

      •The RF OUT connector on the MOCA bridge can not be used to feed a Verizon STB since it blocks the MOCA signals needed by the STB. If you were to do so, you would lose VOD and guide data on that STB. The RF OUT connector can be used to connect a non-MOCA device, such as a TIVO.
      •Except as noted in the MOCA Bridge FAQ linked above, a MOCA LAN bridge can not be used between the ONT and the WAN port of a user router unless it has been certified to operate on channel C4.



    2) Using a MOCA router (Actiontec MI424-WR, Westell 9100EM) as a MOCA LAN bridge.
      2.1) If you want the secondary router to have a static IP address on your network (recommended), you will need to reserve a range of IP addresses on your PRIMARY router.

        •From a PC connected to your primary router, Login to your primary router at 192.168.1.1
        •Click on the My Network icon.
        •Select Network Connections from the left menu.
        •Click on the Network (Home/Office).  The settings page should be displayed.
        •Click on the settings button.
        •In the Start IP Address field, select where you want your DHCP range to start.  e.g.  Change this field to 192.168.1.10 to reserve 192.168.1.2 through 192.168.1.9 for static IP addresses.  192.168..10 through 192.168.1.254 will be reservered for DHCP addresses.
        •Click APPLY.

        2.2) You will need to reconfigure the remote router, BEFORE you connect it to the coax.

          •Perform a hard reset on the secondary Actiontec to restore factory defaults.
          •Connect a PC to a LAN port of the Actiontec. By default, DHCP server should be enabled on the Actiontec, so no need to set a static IP address on the PC.
          •Login to the router at 192.168.1.1

        2.3) Before we can assign a static IP address to the secondary router, we need to reserve a static IP address range on the secondary router.

          •Click on the My Network icon.
          •Select Network Connections from the left menu.
          •Click on the Network (Home/Office).  The settings page should be displayed.
          •Click on the settings button.
          •In the Start IP Address field, select where you want your DHCP range to start.  e.g.  Change this field to 192.168.1.10 to reserve 192.168.1.2 through 192.168.1.9 for static IP addresses.  This step may seem unnecessary since we ar later going to disable the DHCP server, but the firmware in the router checks that the IP address we are assigning is outside the current DHCP range.
          •Click APPLY.

        2.4) Change the remote router's LAN IP LAN address. This will allow the remote router to be accessible at a known IP address for admin purposes.

          •Click on MY NETWORK icon at the top
          •Click on NETWORK CONNECTIONS on the left menu.
          •Click on Network (Home/Office)
          •Click on the Settings button
          •On the IP ADDRESS line, enter an available IP address on the same subnet as your primary router (e.g. 192.168.1.2).
          •Click APPLY.   The router will reboot. 

        2.5) If your primary router's broadband connection is provisioned over coax, you need to disable the remote router's coax WAN connection to prevent it from attempting to become the primary router. If your broadband connection from the ONT to your primary router is ethernet, this step is unnecessary.

          •Click on the MY NETWORK icon at the top.
          •Select NETWORK CONNECTIONS from the menu on the left.
          •Click on Broadband Connection (coax)
          •Click on DISABLE

        If you're using the Westell 9100EM as the remote router, the Westell does not have a button to disable the Coax WAN interface. Instead, follow the directions in this post: http://www.dslreports.com/forum/r24773687
          2.6) Disable the remote router's DHCP server:

            •Click on ADVANCED icon at the top.
            •Click yes
            •IP Address Distribution
            •Select Network (Home/Office)
            •In the IP ADDRESS DISTRIBUTION pull-down, select DISABLED.
            •Click APPLY.
        You may or may not want to disable the wireless section in the remote router. If you leave it enabled, you should set the SSID to the same as your primary router, and set it to use a different channel. This can extend the wireless range of your wireless network.


        2.7) Connect the remote Actiontec to the coax (you may need a 1Ghz 1x2 splitter).



        Having completed #1 or #2, any devices connected to the MOCA bridge should now be able to get an IP address from the DHCP server in your primary router and connect to the internet.

    A MOCA Bridge is an layer 2 ethernet bridge that passes ethernet frames between a MOCA (coax) network segment and a cat5 network segment. The Verizon provided Actiontec or Westell router includes two MOCA bridges.

      •A MOCA WAN bridge which provides coax connectivity between the ONT and the router.
      •A MOCA LAN bridge which provides connectivity between the router and the Verizon Set-Top Boxes (STBs).
    If you have FIOS-TV with Verizon STBs and also want to run your own router as primary, you will need a MOCA LAN bridge between your router and the STBs. You can use the MOCA LAN bridge in the Actiontec for this, or you can use a third-party MOCA bridge. See »Verizon Online FiOS FAQ »What are the tradeoffs between the various router configurations for connectivity options.


    A MOCA bridge is also a good way to extend connectivity into rooms that do not have a cat5 connection. See the following FAQ: »Verizon Online FiOS FAQ »Can I get an ethernet connection in a room with only coax?


    Several third-party MOCA bridges are currently available:

    •Motorola NIM-100 #
    •Actiontec ECB2200 #
    ECB2500 - Available new.
    Netgear MCAB1001 #*
    D-Link DXN-221 #* - Pair or DXN-220 single.
    •Linksys MEB200 #* - No known retail outlet.

      All listed devices have been certified for channels D1-D8 (MOCA LAN). * Indicates device has also been certified for channel C4 (MOCA WAN).

      # Indicates device is manufacturer discontinued. Can frequently be found on ebay, except for the Linksys.
      xygor See Profile has been successful using D-Link DXN-220 as a MOCA WAN bridge between a coax provisioned ONT and a user router. See this post: »Re: Replacing Actiontec router
      At least two people have tried using the MCAB1001 as a MOCA WAN bridge and had problems: »Re: Netgear MCAB1001 on sale on Amazon »Re: FIOS MoCA Help?
      Also, a MOCA router can be used as a MOCA bridge


        •Actiontec MI424-WR router - available used on eBay for $5 - $70, depending on hardware revision.
        •Westell 9100EM - Also available on eBay.

      The MOCA 1.0 specification allows 8 MoCA devices per MoCA channel. Early MOCA devices such as the Motorola NIM-100, first generation Actiontec MI424-WR routers (Rev. A-E), and STBs conform to the MoCA 1.0 specification. Newer MOCA devices conform to the MOCA 1.1 specification which allows 16 devices per channel. Fortunately it is possible to utilize a second MoCA channel. The second MoCA channel is suitable only for extending your LAN over the coax. Your STBs and primary router must remain on the first MoCA channel. You will need two (or more) MOCA bridges in order to utilize a second MoCA channel.

      You can find a list of available MoCA bridges here.

      Click to enlarge

      Note: For clarity, the second MoCA channel is shown in red in the above diagram. As long as the coax runs provide a continuous signal path, devices on either MoCA channel can be connected anywhere on the coax.

      Caution: Not all MOCA devices support all channels.
      • The Westell 9100EM and Actiontec rev. E support channels not available on a NIM-100.
      • The channel on the Actiontec HME-2200 can not be changed (there is no configuration interface).

      Changing the MoCA Channel:


      On the Actiontec or Westell:

      This assumes you are using an additional Actiontec as a MoCA bridge. This should not be attempted if the Actiontec is your primary router. You will lose connectivity to your STBs.

        •Click on the MY NETWORK icon
        •Select NETWORK CONNECTIONS from the menu on the left
        •Make sure ADVANCED view is enabled.
        •Click on coax
        •Select CONFIGURE CONNECTION
        •From the channel pull down, select a specific channel. This must be the same channel used by the MOCA bridge.
        •Make sure MOCA privacy is enabled.
        •In the PASSWORD field, enter a MOCA network encryption password (12-17 numeric characters).
        •Click OK

      On each MOCA bridge:

        •Connect a PC directly to the MOCA bridge.
        •Follow the instructions for logging in to your particular MOCA bridge.
        For a NIM-100, the instructions are as follows. Other MOCA bridges should be similar.
          •Do an IPCONFIG /RELEASE and /RENEW on the PC. The PC should assign itself a 169.254.1.x address since no DHCP server is available.
          •Browse to 169.254.1.1. You should be presented with the NIM-100 login screen. The password is "entropic" (without quotes).
          •Go to the SETUP screen.

            Under LAN
            • Be sure config type is C.LINKLOCAL.
            Under COAX
            •Select the same channel selected on the Actiontec.
            •Select NETWORK SECURITY SETTINGS
            •Enter the same MOCA network encryption password (12-17 numeric characters) that you entered on the Actiontec.
            •Click APPLY

          •Click APPLY on the SETUP screen.
          •Reboot the NIM-100.
          Note: Be careful when changing settings on the NIM-100. It is possible to "brick" the NIM-100.


        After the MOCA bridge is configured, check the coax stats on the Actiontec to verify that each MOCA bridge is communicating.

      There are two MOCA interfaces in the Actiontec/Westell routers:
        • MOCA WAN is used between the router and the ONT (if your WAN connection is provisioned over coax).
        • MOCA LAN is used between the router and the STBs.

      A weak MOCA signal can cause connectivity problems.

      MOCA speeds


      > 200 Mbpsacceptable
      180 - 200 Mbpsmarginal
      < 180 Mbpsunacceptable

      To check the MOCA WAN stats:
        • On the MAIN status page, click on the blue globe in the My Router column. The System Monitoring page is displayed.
        • Click on Broadband Connection (coax). The Broadband Connection (Coax) Properties page is displayed.
        • Click on Settings.
        • Click on Go to Coax WAN Stats. The WAN Coax Connection Stats page is displayed along with the MOCA speeds between the router and the ONT.

      To check the MOCA LAN stats:
        • On the MAIN status page, click on the blue globe in the My Router column. The System Monitoring page is displayed.
        • In the Network (Home/Office) column, click on coax stats. The Coax Connection Stats page is displayed. This shows the MOCA speeds between the router and all MOCA LAN devices. Speeds should be as listed for MCOA WAN.

      Note: Instructions vary slightly for the Westell.

      While FIOS does not use modems, a MOCA WAN bridge can serve a similar purpose.
      »Verizon Online FiOS FAQ »What is a MOCA Bridge?

      Switching the ONT from coax WAN to cat5 WAN is the preferred approach for connecting a third party router.
      »Verizon Online FiOS FAQ »Replacing the Actiontec (part 1): Coax to Ethernet
      However, switching to a cat5 WAN connection is not always practical. When keeping the coax WAN connection is the only option, a MOCA WAN bridge can provide a solution. By placing a MOCA WAN bridge between the ONT and a user router, one can create a layer two bridge between the coax WAN and the cat5 WAN port of a user router.

      Two MOCA bridges that MOCA WAN are available from various sources (eBay, Newegg, Amazon, etc.
      • Netgear MCAB1001 * - available only in pairs.
      • D-Link DXN-221 * - Pair or DXN-220 single.
      Note that the Motorola NIM-100 and Actiontec ECB2200 are not suitable as they do not support the MOCA WAN channel.

      The following instructions were tested with the Netgear MCAB1001. Instructions for the D-Link DXN-221 should be similar.
      If someone goes through this procedure with the D-Link unit, please post exact steps.

      Prepare the Netgear MCAB1001
      Do not connect the MCAB1001 to the coax yet.
      • Connect a PC to the RJ-45 jack on the bridge.
      • Place the bridge in CONFIG mode.
      • Run the supplied disk to configure the bridge.
      • On the COAX page, select channel 9 (1000 Mhz)
      • Set the Diplexer Mode to ALL PASS
      • Press APPLY
      • Disconnect the PC from the bridge
      • Release the CONFIG button
      Note: Although the MCAB1001 is certified for the MOCA C4 channel, this unit is not recommended as it causes interference on other channels. See the notes posted here: »Verizon Online FiOS FAQ »What is a MOCA Bridge?

      Configuring the Actiontec
      These steps are necessary if you have FIOS-TV, since the MOCA LAN connection from the Actiontec is still required for the STBs.
      If you do not have FIOS-TV, you can simply disconnect the coax from the Actiontec.
      • Login to the Actiontec router.
      • Click on the My Network icon.
      • Select Network Connections from the left menu.
      • Select Broadband Connection (coax) from the connection list.
      • Click on SETTINGS
      • Across from DHCP Lease, click RELEASE
      • Click CANCEL
      • Click on DISABLE

      Connecting the bridge
      • Connect the coax side of the MOCA bridge to the main splitter.
      • Connect the ethernet side of the MOCA bridge to the WAN port of your router.
      Your router should now pull a public DHCP lease from Verizon's DHCP server.

      D-Link DXN-220
      For those using the DXN-220, details instructions can be found here:
      »Re: Testing MOCA bridges -- update



      Feedback received on this FAQ entry:
      • I did something similar to this. However, I noticed that the MCA1001 was introducing interference to the COAX and causing a few channels to drop out. Trying to find a fix ATT.

        2012-02-26 09:16:08

      • It works. One point you missed. The privacy option in netgear needs to be enabled and password needs to be copied from actiontec.
