slow internet at home? This adapter is the key to a faster wired connection


  • Much cheaper than professionally installed Ethernet
  • Easy setup that takes minutes
  • It includes everything but persuasion in your walls


  • The maximum speed is slower than Gigabit Ethernet
  • Multiple kits may be required for some combinations
  • It will not work if you still have an active cable TV

It is no secret that most cable and satellite TV services are as well Losing customers to cut the rope As people move to it broadcasting services. For this reason, there’s a good chance your house has hundreds of feet of coaxial cable that was needed for the TV, and is now doing nothing but collecting dust.

It’s this “dark” style represented by a file NexusLink G.HN Wave 2 Ethernet Over Coax Adapter Use to quickly and inexpensively expand your wired home networking options.

If you live in a home that is already connected to Ethernet, or have spent thousands of dollars to add it, you probably don’t need this product. But if you’re in the situation where the vast majority of us find ourselves in, these switches could save you time and money by turning that dark switch into a valuable networking asset.

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

You’ll need either a coaxial cable sticking out of the wall or floor, or a wall-mounted outlet like this one.

The setup process is very simple. The hardest part may be checking which coaxial terminals in your home are connected to. If every one is rated, that’s great. If not, it may require some searching of crawl spaces with a flashlight.

The operation you choose depends on what you want to do with the new connection.

For example, if you want a connection that works from the router in your bedroom to your basement home theater, and you already have a set of in-wall hubs between those locations, you’d put one switch in the bedroom and another in your basement.

The Ethernet cable on the lower end can then either be connected directly to a home theater computer or streaming device, or used to connect an Ethernet switch or secondary Wi-Fi access point for added flexibility.

Rather than suggesting thousands of similar scenarios, I will simply say that almost anything that can be achieved with running Ethernet cables can be easily handled by a series of coaxial cables, as long as you have one of these adapters on both ends.

Each unit is about the size of a small smartphone, but it’s a bit thicker. This makes it easy to store behind a desk or TV.

Easy settings like this are very rare in home networks. But this does not matter if the connection provided by the product is unstable, or does not meet the specifications claimed by the company. I tried to approach the testing process with as much science as possible for the transformers, to check their performance.

I will explain briefly:

  • I’ve replaced running 40 feet of Ethernet cable (Gigabit network adapter > a Gigabit Ethernet port on a desktop computer) with two switches, connected by a 30-foot coaxial cable between them.
  • I ran two tests: one with the original 40ft Ethernet cable running, and another with the adapter setup.
  • I tested two scenarios: download/upload rates and latency numbers when connected to the public Internet, and transfer rates for large files transferred between networked computers.
  • For each scenario I ran five speed tests across three test sites. For each transfer rate test I used four files of different sizes, each transferred five times. Average transfer rate and time are shown here.

Internet Speed ​​Tests

Download (DL) and upload (UL) numbers are in megabits per second (Mbps), while latency (Lat.) is in milliseconds (milliseconds). The test was conducted over a 100Mbps broadband.

consequences: Download and upload results and response time are all in the range of a few percentage points, plus or minus, between the two settings. This means that for gaming and streaming video and audio over the Internet, the switches perform functionally the same as having a similar operating length of the Ethernet network in use instead.

Network file transfer representation


Transfer files over home network test

While the above test showed that the switches were capable of more than the 100Mbps handling that my broadband connection provided, the theoretical speed of my 1Gbps home network proved to be more of a challenge.


File size: average transfer speed in megabytes per second (MBps) | Total transfer time in minutes and seconds

  • 10.14 GB file: 47.5 MB/s | 3:28
  • 1 GB file: 46.5 MB/s | 0:21
  • File 780MB: 46.5MB/s | 0:17
  • File 376MB: 45.5MB/s | 0:07

Ethernet switches via Coax

  • 10.14 GB file: 34.5 MB/s | 4:54 (29% slower)
  • 1 GB file: 35 MB/s | 0:29 (28% slower)
  • File 780MB: 33.75MB/s | 0:23 (26% slower)
  • File 376MB: 34.5MB/s | 0:10 (30% slower)

As you can see, the switches maxed out at about 35 Mbps, while the Ethernet run was around 48 Mbps. This resulted in transfer rates averaging about a third when transferring large files over my wired network.


As you can tell from my testing, the switches seem to max out, at least in this scenario, at around 35Mbps (about 280Mbps). That’s more than any 100Mbps broadband plan you could hope to use, but not as much as the 300Mbps of many popular home internet plans.

However, unless you plan to run many devices through these switches, you are unlikely to reach this maximum transfer rate. It even requires scenarios like 8K video Broadcasting shouldn’t be a problem.

The only time you’ll notice the roughly 30% speed drop you’ve scored is when you compare it to running pure Ethernet when you’re transferring large files between computers on your home network. If this is something you do a lot, it’s worth taking into consideration.

However, given the difficulty, time, and cost associated with installing Ethernet, infrequent slowdowns sound a lot better than spending hundreds, if not thousands, of dollars to replace your existing coax cable with Ethernet.

To be clear, you will need this coaxial cable in place to make this a useful option. But if you’ve already run them through a convenient spot in your home, these switches open up a whole new world of possibilities for the 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.

Alternatives to consider

A slightly cheaper option (if you apply the frequently available Amazon coupon) that bypasses the built-in encryption but still offers theoretical 1Gbps speeds.

Another option that also bypasses the added security, but includes additional coaxial cables for the connections you require.

The predecessor of the converters we looked at in this review. They offer a very similar feature set, but reach a theoretical maximum speed of 1200Mbps, 40% slower than the Wave 2 models we reviewed.
