Most cable and satellite TV businesses are losing users due to cord-cutting as people migrate to streaming services. As a result, there’s a strong probability that your home contains miles of coaxial cable that was once required for TV but is now just gathering dust. The NexusLink G.HN Wave 2 Ethernet Over Coax Adapter utilizes this “dark” coax to easily and affordably increase your wired home networking options.
You probably don’t need this product if your house is already Ethernet-wired or if you spend thousands of dollars to add it. You can, however, transform that drab coax into a valuable networking tool if you find yourself in the majority of situations. This is especially true if you reside in a home where certain areas seem to completely negate even the strongest Wi-Fi connections.
The setup procedure is really straightforward. Verifying which coax connections in your home are connected to which may be the most difficult step. Great if they are all labeled.
One adapter would go in the bedroom, and one would go in the basement, if you already have a co-ax running between your bedroom router and your home theater. The Ethernet cable on the basement end can then be used to connect an Ethernet switch or a backup Wi-Fi access point for further flexibility.
Simple configurations like this one are a delightful novelty in home networking. But if the product’s connection is unstable or falls short of the specifications the manufacturer promises for it, it makes no difference. I made an effort to test the adapters as scientifically as I could in order to evaluate their effectiveness.
File transfer over home network test
While the aforementioned test demonstrated that the adapters could handle the 100Mbps that my broadband connection offers. Then, the far greater theoretical speed of my home network—1 gigabit per second (Gbps)—proved to be more difficult to handle.
As you can see from my testing, the adapters appear to reach their maximum speed at around 35MBps, at least in this situation (about 280Mbps). This is more than any 100 Mbps broadband plan could possibly utilize, while it isn’t quite as much as the 300 Mbps of many widely available home Internet plans.
However, you’re quite unlikely to reach that transfer rate’s maximum unless you’re going to connect a lot of devices to these adapters. Even taxing situations like streaming 8K video ought to be no problem.
Only when you’re moving huge files between PCs on your home network might you notice the roughly 30% performance reduction I measured in comparison with a straight Ethernet run. It’s important to consider if you frequently engage in this activity.
Infrequent slowdowns sound like a far better trade-off than paying hundreds. And if not thousands of dollars to replace old coax cable with Ethernet, though, given the complexity, time, and cost involved with Ethernet installation. A significantly less expensive choice that forgoes the built-in encryption while maintaining potential 1Gbps speeds.
