Wireless internet connections are convenient, but they’re also notoriously unreliable. Nothing proves that point more emphatically than a glitchy video conference call, especially if it’s tied to a crucial business meeting.
The solution, of course, is to run a wired network connection to your home office. Wi-Fi is great for mobility, but a wired connection offers a lot of advantages when it comes to working from home. It’s faster and more reliable, with lower latency, all of which matters if you regularly share large files or participate in high-quality video meetings, or even (ahem) play games.

But setting up a full-time wired connection is easier said than done. Even if you own your own home, running 50 or 100 feet of Ethernet cable is a messy, expensive job. And if you’re living and working in a rented house or apartment, forget about punching holes in walls and ceilings.
Fortunately, there’s a solution, as I discovered some years ago when I moved to a loft-style condo. The cable modem was in the living room, serving up gigabit downloads. My office was at the other end of the house, with Wi-Fi signals that were depressingly weak, thanks to brick walls. I didn’t have Ethernet jacks anywhere in my home, but there were cable outlets in every room. And that unlocked the solution to my bandwidth dilemma.

Those cable outlets were installed – originally – to make it convenient to hook up television sets in every room. As it turns out, the coaxial cable that connects those outlets is also capable of carrying Internet signals, thanks to a technology called MoCA (Multimedia over Coax Alliance). The latest revision of this technology, MoCA 2.5, supports speeds up to 2.5 Gbps.
You can’t plug an Ethernet cable directly into a cable outlet, of course. To make use of that existing coaxial cable requires a MoCA adapter on each end of the connection. That adapter is a simple box that has two connectors on the back – one for a coaxial cable, the other for an RJ45 Ethernet plug.
Using this MoCA adapter, you can create a wired high-speed internet connection.

I was in luck because my Xfinity cable modem<!–> supports MoCA technology directly. As a result, I needed only an adapter for my office PC. I chose the Trendnet TMO-312C Ethernet Over Coax MoCA 2.5 Adapter–>, pictured above. After connecting the adapter to the cable outlet in my home office using a very short run of coaxial cable, I connected it to the Gigabit Ethernet port on my home office PC, using a standard Cat 6 cable.
If your cable modem doesn’t support MoCA directly, you’ll need a cable splitter and a second MoCA adapter to connect to an Ethernet port on the cable modem/gateway. If you have multiple cable outlets in your home or office, you can add a MoCA adapter at each one, and you can plug any Ethernet-compatible device into that adapter — PC, Mac, or smart TV, for example.

You can even use this technology in combination with a Wi-Fi network to add a Wi-Fi access point in a basement, attic, or other location that’s too far from the primary access point to get a reliable signal.
MoCA technology is a great alternative to standard Ethernet wiring, and it costs a tiny fraction of what you’d have to pay to retrofit dedicated Ethernet cabling in your home. It’s a worthwhile option to consider when Wi-Fi simply can’t get from Point A to Point B.
