It's no secret that most cable and satellite TV services are losing customers to cord cutting as people move to streaming services. Because of that, there's a good chance your home has hundreds of feet of coaxial cable that used to be needed for TV, now doing nothing but collecting dust.
These adapters open up a whole new world of possibilities.It's this "dark" coax that theNexusLink G.HN Wave 2 Ethernet Over Coax Adapter makes use of to quickly, cheaply expand your wired home networking options.
If you live in a home already wired for Ethernet, or you've spent thousands of dollars to add it, you likely don't need this product. But if you're in the situation the vast majority of us find ourselves in, these adapters could save you time and money by turning that dark coax into a valuable networking asset.

This is especially true if you live in a home where some rooms just seem to destroy even the strongest Wi-Fi signals.

You'll need either a coaxial cable emerging from your wall or floor, or a wall-mounted port like this one.
Getty ImagesThe setup process is extremely simple. The hardest part might be verifying which coax terminals in your home are connected to which. If each one is labeled, great. If not, it might require some looking into crawlspaces with a flashlight.
These routers are suitable for both your home and the office.
Read nowWhich run you choose depends on what you want to do with the new connection.
For example, if you want a connection running from the router located in your bedroom to a basement home theater, and you've already got a run of in-wall coax between those locations, you'd place one adapter in the bedroom and the other in your basement.
The Ethernet cable on the basement end can then either be plugged directly into a home theater PC or streaming device, or used to connect an Ethernet switch or secondary Wi-Fi access point for additional flexibility.
The kit includes two power adapters and two 6-foot Ethernet cables.
Michael Gariffo/Instead of suggesting thousands of similar scenarios, I'll simply say almost anything that could be accomplished by a run of Ethernet cabling can just as easily be handled by a run of coaxial cable, as long as you have one of these adapters on either end.
If you're interested in using this kit, or another like it, to take advantage of idle coaxial cabling in your home, we've already got a full for you about how to do just that.
Each unit is about the size of a small smartphone, but a little thicker. This makes it easy to stash behind a desk or TV.
Michael Gariffo/Easy setups like this one are a joyous rarity in home networking. But that doesn't matter if the connection provided by the product isn't stable, or doesn't live up to the specs the company claims for it. I tried to approach the testing process as scientifically as possible for the adapters, to verify their performance.

I'll briefly explain:
Download (DL) and upload (UL) figures are in megabits per second (Mbps), while latency (Lat.) is in milliseconds (ms). The test was conducted over 100Mbps broadband.

Results: The download, upload, and latency results are all within just a few percentage points, plus or minus, between the two setups. This means for gaming and online video and audio streaming, the performance of the adapters is functionally identical to having a similar length run of Ethernet in use instead.
While the above test showed the adapters were capable of more than handling the 100Mbps my broadband connection provides, the much faster 1 gigabit per second (Gbps) theoretical speed of my home network proved to be more of a challenge.

Ethernet over Coax adapters
As you can see, the adapters maxed out at about 35MBps, while the Ethernet run got up to nearly 48MBps. This resulted in transfer rates averaging about one third slower when moving large files over my wired network.
As you can tell from my testing, the adapters seem to max out, at least in this scenario, at about 35MBps (about 280Mbps). This is more than any 100Mbps broadband plan could ever hope to use, but not quite as fast as the 300Mbps of many commonly offered home Internet plans.
It's a great time to upgrade your Wi-Fi with the latest mesh networking systems for improved coverage.
Read nowStill, unless you're planning to run many devices through these adapters, you're very unlikely to max out that transfer rate. Even demanding scenarios like 8K video streaming shouldn't be a problem.
The only time you may notice the roughly 30% speed decrease I recorded when compared with a pure Ethernet run is when you're transferring large files between PCs on your home network. If this is something you do often, it's worth taking into account.
However, given the difficulty, time, and cost associated with Ethernet installation, infrequent slowdowns seem like a far better trade-off than spending hundreds, if not thousands, of dollars replacing existing coax cable with Ethernet.
To be clear, you will need that existing coax cable in place to make this a worthwhile option. But if you've already got it running through a convenient spot in your home, these adapters open up a whole new world of possibilities for times when you need the kind of stable, wired connection that even the best Wi-Fi hardware can't provide in every part of every home.
A slightly cheaper option (if you apply the frequently available Amazon coupon) that skips the built-in encryption but still offers 1Gbps theoretical speeds.
Another option that also skips the extra security, but does include extra coaxial cables for connections that require them.
The predecessor to the adapters we looked at in this review. They offer a very similar feature set, but top out at a maximum theoretical speed of 1,200Mbps, about 40% slower than the Wave 2 models we reviewed.
