Ethernet cables offer the best throughput, reliability, and latency for home networking but may require additional wiring in your home.

The primary advantage of using MoCA adapters rather than traditional Ethernet cables is that they provide the convenience of using a home's existing coax cables for Ethernet communication. If you don't want to run Ethernet cables down your hallways or drill holes in your walls, then MoCA adapters may be a great solution.

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.

Powerline adapters offer a similar promise by using your home's AC wiring (power outlets) for Ethernet communication. We believe that MoCA is the clear winner (between MoCA and Powerline) due to the faster speeds and better signal quality. However, there are still some use cases where Powerline may be the best solution.

MoCA adapters can also help with extending Wi-Fi. Or perhaps they can help you avoid the latency of Wi-Fi altogether with a hard-wired network.

Use Cases for MoCA Adapters and Ethernet Cables

Section Link
  • Extend wireless coverage with wired connections to additional Wi-Fi access points.
  • Connect devices that don't support Wi-Fi.
  • Avoid the latency of Wi-Fi while playing games on consoles and computers.
  • Backhaul for a Mesh Wi-Fi System (i.e., a wired backbone for the Wi-Fi satellites).
  • Use wired connections to avoid Wi-Fi interference from neighbors.
  • A secure alternative to Wi-Fi.

Benefits of MoCA Adapters as a Substitute for Ethernet Cables

Section Link
  • Use existing home coax wiring as a replacement for Ethernet cables without drilling new holes in walls/floors.
  • Get Internet access into hard-to-reach places in your home.

What Is MoCA?

Section Link

A pair of MoCA adapters allows you to use a coax cable for Ethernet communication. MoCA adapters behave like an extension for an Ethernet cable. Multi-node configurations can also function as an Ethernet hub.

For example:

  • Suppose you have a cable modem downstairs and multiple computers in various rooms upstairs which need Internet access.
  • You can share the downstairs coax outlet with the cable modem by using a MoCA-compatible coax splitter. The MoCA adapter is then connected to the modem using an Ethernet cable.
  • Upstairs, you can provide Internet access to each computer by connecting MoCA adapters to nearby coax outlets. The computers connect to the MoCA adapters with Ethernet cables.
  • That's it! MoCA adapters are typically plug and play, meaning that no additional configuration is required.

Some modems may include built-in MoCA support, making it so that you only need a single adapter.

Pros and Cons of MoCA

Section Link


  • Fast throughput of up to 2.5 Gbps
  • Use a home's existing coax cables for wiring
  • Plug and play setup (no configuration required)
  • Relatively low latency of 3–6 ms
  • Up to a 91-meter range


  • Requires a Point of Entry (POE) filter for improved security

Pros and Cons of Ethernet Cables

Section Link


  • Low cost
  • Fastest speeds
  • Lowest latency (e.g., for gaming)
  • Secure
  • Up to a 100-meter range
  • Plug and play setup (no configuration required)


  • May require new wiring for your home

MoCA vs. Ethernet Distance

Section Link

Both MoCA and Ethernet distances are more than long enough for most homes.

Max Speeds and Distances
Cable CategoryMax Speed and Distance
Cat 5e
  • 1 Gbps @ 100 meters
Cat 6a
  • 10 Gbps @ 100 meters
Cat 8
  • 40 Gbps @ 30 meters
  • 10 Gbps @ 100 meters
Coax (MoCA 2.5)
  • 2.5 Gbps @ 91 meters
  • 2 Gbps @ 300 meters (actual speeds are often lower)

Do We Recommend MoCA or Ethernet Cables?

Section Link

MoCA is fast and provides a low-latency connection. Because of this, it is an excellent solution for distributing Internet throughout a home that already has coax wiring.

Ethernet cabling is ideal if you build a new home or don't mind running the new cables. Ethernet cables will provide the fastest connections and lowest latencies. However, the performance is so similar that the impact will likely not be noticeable. The convenience of MoCA adapters often outweighs any performance impact.

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.

  • You'll probably want also to buy a MoCA POE Filter if your ISP didn't already install one (for improved security): MoCA 'POE' Coax Filter MoCA 'POE' Coax Filter Check Price on Amazon (affiliate link)

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 goCoax MoCA 2.5 Adapter Check Price on Amazon (affiliate link)
  • You'll need the following additional accessories, if you don't already have them: MoCA 'POE' Coax Filter MoCA 'POE' Coax Filter Check Price on Amazon (affiliate link) Coax Splitter MoCA 5-2300MHz Coax Splitter MoCA 5-2300MHz Check Price on Amazon (affiliate link) 3FT RG6 Coaxial Cable (2 Pack) 3FT RG6 Coaxial Cable (2 Pack) Check Price on Amazon (affiliate link)

  • The TL-SG108 is a well-known and reliable network switch.
  • I own this exact switch model and have been using it without any problems for many years.
  • It supports Ethernet speeds of up to 1 Gbps.
  • Due to the fanless design, it is silent.
  • It uses solid capacitors, which means that it should last a long time.
  • It's an unmanaged switch, meaning that it's plug and play, and no configuration is required. TP-Link TL-SG108 - 8 Port Gigabit Unmanaged Ethernet Network Switch TP-Link TL-SG108 - 8 Port Gigabit Unmanaged Ethernet Network Switch Check Price on Amazon (affiliate link)

Ethernet Cable: Tripp Lite Cat 6a

  • Finding Ethernet cables which comply with their category rating can be a little tricky. Some manufacturers use misleading or incorrect naming, and their cables do not allow you to get the maximum expected speeds. I recommend Tripp Lite's Cat 6a cable.
