MoCA Networking FAQ and Troubleshooting

Print this page


A Multimedia Over Coax Alliance (MoCA) network enables you to send information through the existing coaxial (coax) cable in your home. This gives you both your television programming and Internet content through the same coax cable, making MoCA perfect for transferring and streaming media between TiVo devices.

To learn more about the capabilities of MoCA networking, visit the MoCA website.

Verizon FiOS customers: Currently, Verizon FiOS is the only Internet service provider that gives its customers MoCA-enabled routers. If you have a MoCA-ready TiVo DVR that connects to the Internet through Verizon FiOS, you will need no additional equipment to enjoy MoCA connectivity.

MoCA FAQ


Do I need any additional equipment to use MoCA?

Here is a list of MoCA networking equipment. Not every setup needs every piece of equipment—read each section to determine what equipment you need.

MoCA Network Adapter

The MoCA Network Adapter (also called an Ethernet-to-Coax Bridge, or ECB) is what lets your DVR access the MoCA network. You need one MoCA Network Adapter for each non-MoCA-enabled device on your MoCA network (including your router). Refer to this table to determine which DVRs need a MoCA Network Adapter:

DVR model Can I use it on my MoCA network? Does this DVR need a MoCA Network Adapter?
Roamio Plus / Pro Yes No
4-Tuner Roamio Yes Yes
Premiere 4 / XL4 / Elite Yes No
Other Premiere series DVRs Yes Yes
Series3 HD / HD / HD XL Yes Yes
Series2 DT Yes Yes
Series2 ST No  
Series1 No  

IMPORTANT: Remember that you will also need a MoCA Network Adapter for your router (unless it is a MoCA-enabled router).

POE Filter

A Point of Entry (POE) filter is an optional piece of equipment which keeps MoCA signals concentrated in your home and improves the performance of your MoCA network.

Coax Splitter

This small piece of equipment splits one coax input into two or more outputs. For most setups, you only need a splitter with two outputs; however, some setups require more outputs.

In most cases, you (not your cable provider) are responsible for providing your MoCA equipment. The TiVo Store has most of the equipment you need for MoCA networking.


Will a signal amplifier interfere with my MoCA network?

TiVo doesn't recommend using a signal amplifier on a MoCA network. Amplifiers can block communication between devices and cause them to disappear from the network.


Can I use MoCA in my dorm or apartment building?

No. Networks in dorms or apartment buildings don't allow you to add a POE filter to your specific connection. Without the POE filter, two things could happen:

  • Your MoCA network could be visible and/or accessible to anyone in your dorm or apartment building that uses a MoCA-enabled device.
  • Your MoCA network might disappear or cease to function if people in your dorm or apartment building install their own MoCA networks.

MoCA Troubleshooting

If you receive a numbered error message, refer to the troubleshooting steps at MoCA Network Errors.


Use the following steps to troubleshoot connection issues, stuttering video, or the inability to see other TiVo devices on your network.

Make sure all devices have power and are connected to your network

  1. Verify that you have plugged in all equipment and that all the indicator lights are on.
  2. Verify that the TiVo equipment is connecting through the same network.
  3. Confirm that all of your equipment is connected using the same coax line.

If using a MoCA Network Adapter, check that it displays three lights

  1. If you do not see three lights, verify that the power, Ethernet, and coax cables are not damaged.

  2. NOTE: Damage to cables is not always visible. If these troubleshooting steps do not resolve your issue, TiVo recommends that you replace the cables even if there is no visible damage to them.

  3. Disconnect and reconnect the power, Ethernet, and coax cables.
    • Connect the Ethernet cable to another output on the router.
    • Make sure the coax cables are connected to the same splitter.
  4. Set up the network again in Network Settings on the DVR.
  5. If you are using a DVR in Bridge mode to create the MoCA network, make sure that:
    • Both the coax and Ethernet cables are plugged in securely.
    • You have enabled MoCA in Network Settings.

Verify that other devices on your MoCA network can connect to the Internet

I cannot get any devices to connect to the Internet

Contact the person or company that helped you set up your MoCA network.

Only my TiVo equipment will not connect to the Internet

Continue to the next step.

Check the MoCA loops

  1. You can only have one device creating the MoCA network. Verify that you have only one MoCA Network Adapter or MoCA-enabled TiVo DVR connected to your router.
  2. Verify you have not accidentally connected both a coax cable and an Ethernet cable to a MoCA-enabled DVR on your MoCA network. Doing so automatically enables Bridge mode, and the TiVo DVR will attempt to create another MoCA network rather than use the current network.

Check the PHY rates on the MoCA-enabled TiVo DVR

PHY rates only appear on MoCA-enabled DVRs.

  1. Go to the View Network Status screen:

  2. From TiVo Central > Settings & Messages > Settings > Network > View Network Status

  3. You see a TX and RX PHY rate for each MoCA node. Each node represents a MoCA device.

An ideal PHY rate is 180 or higher to achieve a throughput of 100Mbps (this is required to achieve three simultaneous streams from a single DVR). The PHY rate can drop as low as 130; however, this can cause choppy video, distorted audio, or other quality issues.

How do I fix a low PHY rate?

Many factors can affect the PHY rates, including poor-quality cables, damaged cables, cables that run too long, and bad connectors or coax splitters. If you are unable to determine what is causing the PHY number to drop too low (below 130), contact your cable company or an independent professional for assistance.
