If you find your online games lagging or your Zoom meetings glitching, you may want to try a powerline adapter to improve your home’s connectivity. 

These devices connect to your router and will help improve that connection.. We’ve rounded up the best powerline adapters available this year. 

What is a powerline adapter?

A powerline adapter is a device that helps you connect to the internet using the electrical wiring in your home. It actually comes with two separate adapters — one that plugs into a wall outlet where you want to extend your connection and another that plugs into your internet router. Like mesh networks, powerline adapters are a great solution if you’re struggling to extend your internet connection to distant corners of your home. 

Like traditional wired internet, powerline adapters use an Ethernet cord. But rather than connecting  your device to the router, you connect it to one of the adapters, 

One adapter takes the internet signal from your router and broadcasts it to the other adapter through your home’s electrical wiring. You can then connect your device to the adapter with an Ethernet cord. 

You can generally expect your powerline adapter to give you the same internet speed as if you connected your device directly using an Ethernet cord. The difference is that rather than having to work directly next to your internet router, you can work from anywhere in your home and still get the same great connection. 

When it comes to choosing the right powerline adapter, pay attention to the advertised speed, connectivity and any special features included.

What are the benefits of powerline Ethernet adapters?

There are several reasons someone might want to use a powerline adapter. First, these devices are beneficial because they’re generally faster than Wi-Fi speeds. If you struggle with a poor or unstable Wi-Fi connection in your home, a powerline adapter could be a great fix.

Powerline adapters also provide a stronger signal than Wi-Fi, meaning you can do more at once. This type of connection is well-suited for online activities like gaming, video streaming or transferring large amounts of data.

How we chose our favorite powerline adapters

When searching for the best powerline adapters, our goal was to find the ones that provided the best value, meaning a combination of outstanding features at a good price. We compared eight adapters using the criteria of speed, price, features and customer reviews. From there, we narrowed it down to our four favorites.

We didn’t just include four adapters with the fastest speeds. Our goal was to find those that offered speed with other important factors, such as budget and unique features. Prices for powerline adapters range from around $60 to $120, depending on how much speed you need.

The TP-Link device comes with a thoughtful design that includes dual Ethernet jacks on the bottom, as well as a passthrough outlet so you aren’t sacrificing outlet space to use it.

The kit comes with two adapters with 1,300 Mbps speed and a range of nearly 1,000 feet. The speed isn’t as fast as some of its competitors, but it makes up for it with an excellent price and many outstanding features.

This Netgear device comes with speeds of 1,000 Mbps. It also has a Push-and-Secure button, allowing you to instantly encrypt your powerline network connection. Unfortunately, because of the wireless capabilities, this device comes at a slightly higher price point.

Powerline Ethernet adapter buying tips

When you’re preparing to buy a powerline Ethernet adapter, there are a few tips to keep in mind:

  • Shop for the latest technology. HomePlug AV2 is currently the most advanced powerline protocol and will give you the best speed and widest range of connection.
  • Consider the size of your home. In a larger home where you’re working far from the internet router, it’s important to shop for an adapter with the widest range.
  • Prioritize encryption. Everyone wants to keep their data safe. Be sure the powerline adapter you choose comes with the best encryption technology.

Need a faster internet plan?

A powerline adapter can help speed up your internet, but it can only do so much on its own. To get the best your adapter has to offer, you must also pair it with a solid internet plan. If you’ve purchased an adapter but it isn’t working as you hoped, consider upgrading your internet.

The best internet providers vary depending on where you live. Shop around for the best plans near you, keeping in mind download speeds, data caps and service areas.

The bottom line

If you find yourself regularly gaming or streaming videos and find that your internet can’t keep up, a powerline adapter might be just the solution. For the best speeds, the TP-Link TL-PA9020P and Netgear PLP2000 are our favorite devices and the best for the money. But remember that your powerline adapter can only be as good as your internet service plan, so consider upgrading that first.
