Quick Answer:
A coaxial cable to Ethernet adapter—more commonly known as an ethernet coax adapter—is a simple device that lets you convert the coaxial cable wiring already in your walls into a fast and reliable Ethernet network. This is especially helpful in homes where WiFi isn’t strong enough or you want a hardwired connection without installing new Ethernet cables. The most popular and reliable type of ethernet coax adapter is called a MoCA adapter.
What is an Ethernet Coax Adapter and How Does It Work?
An Ethernet coax adapter makes it possible to send Ethernet data signals over existing coaxial cables—the same ones used for cable TV or Cable Internet services. Instead of installing new Ethernet wires in your walls, you can use an Ethernet coax adapter, like Hitron’s HTEM5 MoCA 2.5 adapter, to instantly create a high-speed wired connection anywhere you have a coax outlet.
Why Would I Need an Ethernet Coax Adapter?
If your WiFi struggles to reach certain rooms—or you just want faster, more reliable connections—an Ethernet coax adapter is the perfect solution.
Typical use cases include:
- 4K Streaming: Smooth, buffer-free video even in far corners of the house.
- Online Gaming: Low-latency connections without lag or interruptions.
- Home Offices: Reliable Ethernet speeds for video conferencing and large file uploads.
Instead of relying on WiFi extenders, you can have a true wired connection with minimal setup.

How Do I Set Up an Ethernet Coax Adapter?
You need two MoCA adapters to create a working Ethernet-over-coax connection:
- Connect one MoCA adapter to your modem or router with an Ethernet cable, then connect it to a coax outlet.
- Connect your second MoCA adapter to your device via Ethernet (like a gaming console, streaming box, or computer) and plug it into another coax jack in your home.
- Power on both MoCA Adapters. Your home’s coax cables carry the Ethernet data between the two points.
That’s it—no configuration needed. Products like the Hitron’s HTEM5 MoCA Adapters are true plug-and-play devices, making setup hassle-free.

Important Notes Before Buying
- Check your Internet provider: MoCA works best with Cable Internet (e.g., Xfinity, Spectrum, Cox). It is not compatible with DSL or Fiber Internet.
- Look for MoCA 2.5 support: This version offers the best speeds and performance.
- You don’t need a new modem: MoCA adapters work independently from your modem and router setup.
- Some modems/routers have MoCA built-in: If yours does, you may only need one adapter.

FAQs
Will an Ethernet coax adapter work if I have cable TV?
Yes. MoCA adapters operate on a different frequency than cable TV signals, so they can coexist without interference.
Do I need two adapters?
If your router or modem doesn’t have built-in MoCA support, you’ll need two adapters—one at your router and one at your device.
What Internet providers are compatible with Ethernet coax adapters?
Ethernet coax adapters like the HTEM5 work with most Cable Internet providers, including Xfinity, Spectrum, Cox, and Optimum.
How fast is Ethernet over coax?
With a MoCA 2.5 adapter like Hitron’s HTEM5, you can achieve speeds up to 2.5 Gbps, offering more than enough bandwidth for 4K streaming, video calls, online gaming and large downloads.
Do ethernet coax adapters improve WiFi?
Indirectly, yes. By offloading devices to a wired Ethernet connection via coax, you reduce congestion on your WiFi network, which can improve overall wireless performance.
Can I use an Ethernet coax adapter with satellite Internet?
Not typically. Satellite systems often use different coax configurations that are not MoCA-compatible.
