MoCA vs. Powerline? - Which You Should Buy (2023)

Find out if MoCA adapters (Ethernet over coax) or Powerline adapters (Ethernet over powerline) are better for your home Ethernet network.

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. Powerline adapters offer a similar promise by using your home's AC wiring (power outlets) for Ethernet communication. MoCA and Powerline adapters may solve your problems of extending Wi-Fi. Or perhaps they can help you avoid the latency of Wi-Fi altogether with a hard-wired network.

We believe that MoCA is the clear winner due to the faster speeds and better signal quality. However, there are still some use cases where Powerline may be the best solution, which I discuss in this article.

Below, you can find our recommended Recommended MoCA Adapters and Recommended Powerline Adapters.

Use Cases for MoCA and Powerline Adapters

Section Link
  • Use existing home wiring as a replacement for Ethernet cables.
  • Extend wireless coverage.
  • Backhaul for a Mesh Wi-Fi System (i.e., a wired backbone for the Wi-Fi satellites).
  • 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.

What Is MoCA?

Section Link

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.

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)


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

What Is Powerline?

Section Link

Powerline adapters behave much like MoCA adapters. You can create an Ethernet network by simply plugging a pair of Powerline adapters into your wall outlets. Powerline adapters can communicate over the same wires as you use for AC power transmission.

Pros and Cons of Powerline

Section Link


  • Easy wiring using existing power outlets (connect an Ethernet cable)
  • Low cost (compared to MoCA adapters)
  • Encrypted (some products)
  • Up to a 300-meter range
  • Some models have built-in Wi-Fi
  • Plug and play setup (no configuration required)


  • Often a lower connection speed of around 150-350 Mbps compared to the advertised 1-2 Gbps
  • Powerline devices need to be on the same electrical circuit
  • May cause noticeable electromagnetic interference with some devices such as speakers (static sound)
  • Power strip, GFCI outlets, and AFCI circuit breakers may degrade Powerline network signals
  • Some models block an outlet when connecting directly into a wall outlet

MoCA vs. Powerline Distance

Section Link

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

Do We Recommend MoCA or Powerline?

Section Link

Suppose your Internet speed is less than 200 Mbps or your devices on the network do not support gigabit Ethernet. In these cases, Powerline adapters may be the best of the two options for you, as they offer a lower price point.

On the other hand, MoCA adapters are a better option when you want to fully utilize a higher-speed Internet connection and have existing coax cabling between rooms.

You could also consider using both! For example, MoCA adapters might work great for connecting an upstairs and downstairs via coax. At the same time, Powerline adapters would be great for getting Internet to a garage that has no coax line available.
