How Do I Convert Coax to Ethernet?

Learn > MoCA > How Do I Convert Coax to Ethernet?

In the US, 90% of homes have coaxial (coax) cable wiring.  This coax wiring is designed to transmit very high-bandwidth video signals, and, because of this, it’s perfect to transform into an Ethernet network.

You can convert your coaxial cable TV wiring in your home to an Ethernet connection, using a small device called a Coax-to-Ethernet Adapter (also called a MoCA Adapter), that will make your Internet and WiFi connection faster and more reliable.  Here’s how it works.


Converting Coax to Ethernet


Converting your coax wiring into an Ethernet connection is a great way to extend your Ethernet without having to run any wires!  Coax to Ethernet Adapters are an economical and hassle-free way to achieve an Ethernet connection without having a weekend-long wiring project.

But first, some terms to get familiar with:

Coax to Ethernet Adapters (MoCA Adapters) – are adapters that transform your coax wiring into an Ethernet connection.  These adapters can also be called MoCA Adapters or MoCA Network Adapters.

MoCA – MoCA is a technology protocol developed by the Multimedia over Coax Alliance (aka: MoCA Alliance) who develop coaxial connectivity standards.

MoCA Network – a MoCA network is formed when a minimum of two MoCA-enabled devices, such as Coax to Ethernet Adapters or a cable modem with MoCA capabilities connect over coaxial cable wiring.

How Does It Work?


MoCA adapters are capable of Gigabit speeds and work by transforming your home’s existing coax TV wiring and cable outlets into an Ethernet connection, sending that increased bandwidth to every device connected to your new MoCA network.


Both Wired and Wireless

A MoCA network is the best of both worlds – wired and wireless. Because MoCA adapters perform the conversion of coax wiring into an Ethernet network, you get a wired connection that won’t be affected by interference, giving you a reliable and fast Internet backbone. MoCA adapters are also compatible with virtually any device with an Ethernet port, which means you can connect to a wireless router, mesh WiFi access point, gaming or streaming devices.


Compatible with Ethernet Devices

Ethernet over Coax Adapters have both a coax port and an Ethernet port on the back.  You can plug in any Ethernet device, such as a WiFi router, computer, gaming console and much more, into the Ethernet port to connect that device to your MoCA network.


Network Size

You can have up to 16 Coax-to-Ethernet Adapters or MoCA devices connected to your MoCA network.  This is more than enough capacity for even a super-user.



Coax to Ethernet Adapters are capable of high-performance data speeds up to 2.5 Gbps within the MoCA network, and up to 1 Gbps to your end devices.


Not Compatible With

Coax to Ethernet Adapters are not compatible with satellite TV or AT&T U-verse Coax networks.


MoCA Network Security

MoCA networks are extremely secure, however, MoCA signals by their very nature, seek each other out.  This means that a MoCA signal filter should be placed at the point of entry of your Internet connection into your home, to ensure your MoCA signal does not seek out other MoCA signals coming from a neighboring home.

Easy Plug N’ Play Set Up


So simple – just plug them in.  Coax to Ethernet Adapters automatically “see” each other to create an instant MoCA network as soon as they are plugged in.

You will need two MoCA adapters if your modem or router does not have MoCA built in.

Setting up your Coax to Ethernet adapter takes two easy steps:

Step 1: Take one HTEM4 adapters and connect it into a coax TV outlet using a coax wire. Then, using an Ethernet cable, connect your router to the HTEM4 adapter.

Step 2: Take the second HTEM4 adapter and connect it to any other coax outlet in your home. It should establish a MoCA network link automatically with the router.

With MoCA adapters, you can enjoy wireless Internet and also get a wired network experience with reliable, solid Internet connection.

Get A Better Home Network


Better WiFi Bandwidth
Turn your existing coax TV outlets into a Gigabit Ethernet network connection between your home’s router and WiFi access points. These faster speeds to your WiFi Access points mean faster WiFi performance to all of your wireless devices.

Better Video Streaming
Coax to Ethernet (MoCA) adapters create an extremely stable wired network connection that allows you to stream 4K and HD video without buffering or freezing. 

Better Online Gaming
Your MoCA network’s high-speed wired connection lowers latency and combats lag, so you don’t have to worry while online gaming.

Faster WiFi Speeds and Better Coverage
Using Coax to Ethernet adapters to create a MoCA network that is capable of Gigabit speeds, you can increase your WiFi speeds and coverage delivered to any of your coax outlets that has a Coax to Ethernet Adapter.

Better Experience Working from Home
A MoCA network makes working from home and video conference meetings a better experience. You will get a smooth, seamless connection to do your job even when the rest of the household is also connected to the Internet at the same time.

By simply using HT-EM4 MoCA adapters, you can enhance your WiFi connection and Internet experience to every corner of your home.
