Best powerline extenders for 2024

With one of the best powerline extenders, you can use your home’s electrical wiring to eliminate Wi-Fi dead spots and get internet in places one of the best Wi-Fi routers may not be able to reach.

Unlike with one of the best Wi-Fi extenders, you just have to plug one of the small boxes into an AC outlet next to your router and another where you want the data to end up to set up a powerline extender. This makes for a simple setup process, especially since there aren’t any passwords, software or configurations you need to worry about. We’ve tested and reviewed the best powerline extenders with an emphasis on data throughput, signal range and value – including the device’s price, design and electricity consumption – to help you find the right one for your home.

These are the best powerline extenders you can get today but if you find they don’t do the trick or work with your home’s wiring, you might want to consider upgrading to one of the best mesh Wi-Fi systems instead.

The best powerline extender overall

It’s a close call, but the Netgear PLP2000’s superior throughput trumped the TP-Link’s TL-PA9020P’s extended range, making it our choice as the best Powerline adapter. With the ability to move more data, the PLP2000 outperformed the crowd and filled a previously unconnected garage with more than enough data to watch videos, play games and live online. 

It may be one of the largest PL extenders available and not include a monitoring utility, but the PLP2000 provides an AC outlet to make up for the one it uses and its two gigabit Ethernet ports provide data for a TV and a computer. While at $110 it’s among the most expensive PL extenders, it includes a one-year warranty and only 90-days of support, while its peers include a year or two of warranty and support. 

Netgear’s PLP2000 can push data into unconnected parts of a home at peak performance and is the one to get.

The best powerline extender on a budget

Despite its short range and middling performance, the D-Link DHP-601AV’s two-prong plug can help bring data to older homes that lack ungrounded three-prong outlets. Small and easy to hide, the DHP-601AV has three LEDs to show network status but falls short by lacking an AC passthrough outlet to make up for the one it uses. With a single Ethernet port, a powerline network composed of DHP-601AV units will need a networking switch to connect to more than one device. 

Although several competitors provide a monitoring and configuration utility for adjusting the parameters of the powerline network, the DHP-601AV has none. On the other hand, it sips electricity while others gulp it and could cost only $2.40 a year to operate. That, along with its $60 price tag, means the DHP-601AV is cheap to keep for an older home.

The best powerline extender value

The Trendnet TPL-423E2K is for those who care more about value and a three-year warranty than getting the top performance, extra range or the ability to service two networked devices. Overall, the TPL-423E2K offers the enviable combination of low upfront price and low operating costs, making it the one for penny-pinchers to get.

What the Trendnet TPL-423E2K lacks in speed and range it more than makes up with a handy AC passthrough outlet, a useful utility and a class-leading three year warranty. At $70 for the set, the TPL-423E2K is a must-have for those who choose low costs and reliability over all-out performance in powerline devices. The Trendnet TPL-423E2K offers affordability and the assurance that it will work for years, even if that function doesn't have the range and bandwidth of more expensive competitors.

The best powerline extender for range

TP-Link’s TL-PA9020P can help fill a big home with powerline data thanks to its class-leading range. It may be off the blistering pace set by the PLP2000, but the TL-PA9020 has the power to push data through more than 1,000-feet of electrical wiring and delivered top-speed to a previously unconnected garage. Its pair of Ethernet ports and AC passthrough outlet mean that it not only won’t hog your home’s outlets but can supply data to two devices, like a smart TV and a computer. 

While its monitoring and configuration utility lets you customize your powerline network by renaming the devices and adjusting the Quality of Service parameters of the TL-PA9020P, its thirst for electricity makes it expensive to use and its side-mounted LEDs can be hard to see. Still, the $90 TL-PA9020P can fill a big home with data.

The best powerline extender for simplicity

The Zyxel PLA5456 is big and combines a pair of Ethernet ports with a useful monitoring utility and a handy AC passthrough outlet. It will help push data throughout your home, but it's big, and delivers adequate (if unexceptional) performance and range. It’s no bargain for the two devices, but the PLA5456 is for buyers looking for a powerline extender that quietly does its work behind the scenes.

Provided you don't need the better performance required for uses like streaming video or gaming, the Zyxel might be a good fit for homes with less-intensive data needs. The shorter range and limited bandwidth are enough to support basic online activities like web browsing and social media, but are unimpressive compared to our top models. Nonetheless, the design offers some convenience with it's added AC outlet, and sales prices could still make the Zyxel a smart buy.

How to choose the best powerline extender for you

Powerline extenders offer a discreet way to replace long lines of Ethernet cable with the electric wiring that’s already in your walls. This makes them a great option for anyone that wants to stretch their network connectivity to new rooms and rid their home of Wi-Fi dead spots. But is a powerline extender right for you?

There are two other options worth considering when you want to get better connectivity in the furthest reaches of your home. The first is a signal booster, like those in our guide on the best Wi-Fi extenders, which can capture and rebroadcast a wireless signal to help boost the reach of your Wi-Fi router. That’s a perfectly good option when you have continuous Wi-Fi between the router and the extender. If a far room shares electric wiring with your router but the Wi-Fi signal from your router doesn’t reach far enough for a wireless extender, then a powerline extender is the better choice.

The other alternative is upgrading to a mesh Wi-Fi system which uses multiple units to provide a single seamless Wi-Fi network that can easily cover even the largest homes with a strong wireless signal. However, the switch from a standard router to a mesh router can be expensive which is why we've also rounded up the best cheap mesh Wi-Fi systems under $100. If you want to stretch your network without paying a few hundred dollars, it’s worth trying a powerline extender first. 

How we test powerline extenders

To evaluate each of the powerline extenders we review, we test each in a variety of ways. In addition to price and physical design, we also take a closer look and test their throughput, range and bandwidth over distance as well as temperature and power consumption.

Throughput: To measure the range of each powerline set, we plugged the sending unit in at a home’s circuit breakers and the broadband modem and the receiver at an AC outlet 10-feet away.

Wired Range: After measuring throughput, we added a series of 100-foot grounded extension cords and measured the available bandwidth. With the system disconnected, we removed the last cord and added 50-, 25-, 12- and up to two 6-foot cords. The range is the total length of the extension cords that delivered the lowest throughput without disconnecting.

Bandwidth: We also set up the receiver in a garage that’s about 100-feet from the sending unit and measured the bandwidth. We finished this round of testing by watching HD videos, playing games online and visiting a number of websites.

Temperature and Power Consumption: While watching videos we measured each device’s peak temperature with a Fluke 62 mini IR thermometer. We also measured power consumption (both in use and while idle) using a Kill A Watt Edge power meter. Assuming the gear is active half of the day and sits idle for the rest, we multiplied each power-use figure by 4,380 (365 days times 12 hours a day) and added the results together. Then, we doubled the total for the two devices needed and divided by 1,000 to get the annual energy use in kilowatt-hours. Finally, we multiplied this by $.13 (the average price of a kilowatt-hour) to get our estimate of annual operating cost. 

Behind the scenes, we used a Linksys WRT32X router, a 200Mbps Internet connection, a Lenovo ThinkPad T470 notebook and the Speedtest app to measure throughput. For all testing, five data points were averaged.
