MoCA support on a modem router combo device allows you to use a coax cable for Ethernet. In other words, your home network can use your home's TV or internet coax cables rather than Ethernet cables.
The popular new use case for this is to use MoCA as an Ethernet backhaul for your Wi-Fi Mesh network.
Coax Ethernet backhaul means that you are using your home's coax wiring with MoCA adapters to connect the router to the satellite nodes. Wired backhauls will result in a fast connection throughout your house, ideally without needing additional in-wall wiring.
MoCA adapters in a home network adapt an Ethernet cable to a coax cable and then back to an Ethernet cable. However, MoCA adapters allow for a multi-point network, connecting multiple Ethernet cables as a hub does. You can use MoCA Home adapters for extending any network or internet connection over a coax cable.
Modem router combo devices with built-in MoCA support act as a MoCA adapter. Built-in MoCA support means only one additional MoCA adapter is required to form a MoCA network.
I don't currently recommend purchasing a new modem router combo device with built-in MoCA support as the presently available devices only support MoCA 1.1 speeds. Instead, if you don't already have a modem router combo device with MoCA support, I'd recommend getting standalone MoCA adapters.Actiontec ECB7250 Bonded MoCA 2.5 Network Adapter Check Price on Amazon (affiliate link)
- Backhaul for a Mesh Wi-Fi System (i.e., a wired backbone for the Wi-Fi satellites).
- Extend wireless coverage.
- Use existing coax cables as a replacement for Ethernet cables.
- Get Internet access into hard-to-reach places in your home.
- Use wired connections to avoid Wi-Fi interference from neighbors.
- Avoid the latency of Wi-Fi while playing games on consoles and computers.
- A secure alternative to Wi-Fi when using a MoCA POE Filter.
MoCA, which stands for Multimedia over Coax Alliance, is a standards group that defined how networking can occur over coax cables via MoCA Adapters.
MoCA was initially developed for streaming video over the Internet for set-top boxes and smart TVs but is now available for general use in home networks.
The primary advantage of using a MoCA network rather than traditional Ethernet cables is that it provides the convenience of using a home's existing coax cables for Ethernet communication.
The example below has a MoCA adapter connected to the primary Wi-Fi router.
If you have a modem router combo that supports MoCA, your setup is even more straightforward! The upper left MoCA adapter in the diagram isn't needed.
MoCA adapters can be an excellent choice for distributing Internet and network access for homes already wired with coax cabling. MoCA adapters can create a high-speed, low-latency, and reliable network connection to any room in a home. The performance of MoCA adapters makes them perfect for gaming or streaming 4K content on your TV. MoCA adapters provide a hard-wired solution while avoiding the need to drill holes or run additional Ethernet cables.
Mesh Wi-Fi Systems are becoming more popular as they simplify getting Wi-Fi signals into hard-to-reach locations of a home. They create a Wi-Fi network with multiple Wi-Fi access points to spread out the Wi-Fi coverage. Each of these Wi-Fi access points is called a satellite node.
However, as each satellite node in a Mesh System is just repeating Wi-Fi data to transport it to and from the router, there may be a performance penalty.
To avoid the lower performance via satellite nodes, you can run Ethernet cables between the main router and satellite nodes. Using this wired connection is called "Ethernet Backhaul."
The drawback to using only Ethernet cables is that your home may not already be wired for Ethernet. To avoid adding additional Ethernet wiring, you can instead use MoCA as a coax Ethernet backhaul.

Setting up a MoCA Home network is quite simple, as it often requires no software configuration.
- If you have a router that supports MoCA already, you need a minimum of one additional MoCA adapter.
- If your router does not support MoCA, or you want to create a separate coax network for MoCA, then you'll need at least two MoCA adapters. Actiontec ECB7250 Bonded MoCA 2.5 Network Adapter Check Price on Amazon (affiliate link)
MoCA adapters may come with short Ethernet cables, coax cables, and a coax splitter.
- If your MoCA adapters don't come with Ethernet cables, you'll need Cat 6 or Cat 6a Ethernet cables for each adapter. Tripp Lite Cat6a 10G Patch Cable 3ft Check Price on Amazon (affiliate link)
- If your MoCA adapters don't come with coax cables, you'll need short RG-6 coax cables to connect each adapter to the wall. 3FT RG6 Coaxial Cable (2 Pack) Check Price on Amazon (affiliate link)
- If your MoCA adapters don't come with coax splitters and you are connecting multiple cables, you'll need MoCA compatible coax splitters that support up to 1625 MHz. Coax Splitter MoCA 5-2300MHz Check Price on Amazon (affiliate link)
- To ensure that the MoCA communication is not accessible by a neighbor, you'll need to ensure that the coax cable coming into your home has a MoCA POE Filter. MoCA POE Filters block 1 GHz frequencies and also reflect them, which improves MoCA communication. MoCA 'POE' Coax Filter Check Price on Amazon (affiliate link)

Best MoCA 2.5 Adapter: Actiontec ECB7250 Bonded MoCA 2.5 Network Adapter
While older versions only use a 1 Gbps network port, the ECB7250 uses a 2.5 Gbps Ethernet port, allowing for maximum network utilization.
I own a pair of these adapters, and they work great!
Includes most of what you'll need, including two adapters and power supplies, two network cables, two coax cables, and a coax splitter.
The manufacturer could improve the instructions regarding using the MPS button for encryption, but that won't be needed for most installations.
Initial installation is very straightforward.

Value MoCA 2.5 Adapter (1 Gbps Port): GoCoax MoCA 2.5 Adapter
- This adapter should work almost as well as the Actiontec ECB7250 adapter, with a few exceptions:
- The Ethernet ports only support a 1 Gbps Ethernet connection, rather than 2.5 Gbps.
- It doesn't include a MoCA-capable coax splitter or coax cables. goCoax MoCA 2.5 Adapter Check Price on Amazon (affiliate link)

Best MoCA Wi-Fi Extender: Actiontec WCB6200Q
The Actiontec WCB6200Q is an excellent solution if you:
- Have a modem-router combo with MoCA support; or
- Want to use MoCA for Ethernet backhaul from this Wi-Fi extender to the router.
4x4 802.11AC Wi-Fi can use the full bandwidth of the MoCA 2.0 bonded connection (1 Gbps) with devices that support streaming to all four antennas (4x4 MIMO).
It only supports MoCA 2.0 Bonded speeds, but that should be enough for most internet streaming purposes.

- MoCA is incompatible with Satellite TV, Dish, Direct TV, and AT&T U-verse TV, which use the same frequency bands.
- Fios/Xfinity: Some people have experienced compatibility issues when using Xfinity DVRs, as they communicate using MoCA frequencies. The most straightforward workaround is to prevent communication with the Fios/Xfinity devices by configuring the MoCA adapters to use D-band high-end frequencies at 1400 Mhz and above. Xfinity uses 1150 MHz frequencies for MoCA on LAN networks. In this configuration, you would need at least two MoCA adapters. If this sounds too advanced for you, you could consider Powerline adapters, which I discuss in MoCA vs. Powerline.
- Coax amplifiers and splitters will need to support the frequencies of up to 1625 MHz used by MoCA. Coax Splitter MoCA 5-2300MHz Check Price on Amazon (affiliate link)
- Using MoCA over RG-6 coax cables is best, but it may still work over older cables.
- MoCA adapters are generally backward compatible but will run at lower speeds when used with older versions.
MoCA POE Filter
MoCA Point of Entry Filters filter out the 1 GHz+ frequencies used by MoCA devices.
MoCA POE Filters are beneficial for privacy, to prevent leaking data to your nearby neighbors, as well as reducing noise on the line.
They also reflect the MoCA frequencies, which can be desirable for improved MoCA device communication.
Your cable provider may have already installed a MoCA POE Filter with one of these labels:
- Do not remove—Required for multi-room DVR operation
- Do not remove—Required for whole-home DVR operation
- Do not remove—Required for any-room DVR operation
Despite the phrasing, these filters also apply to MoCA adapters for Ethernet usage. The main reason for this wording is that DVR set-top boxes are a more common usage of MoCA.MoCA 'POE' Coax Filter Check Price on Amazon (affiliate link)
