With more of us working from home and using streaming entertainment services, having a fast home network is now as essential as a kettle or gas central heating. The quickest way of improving your home network speeds is adding Powerline adapters to the rooms that need the speed. Fear not, they are super easy to install.
What are Powerline adaptors?
Powerline is a simple-to-install digital home technology that can provide faster speeds than Wi-Fi for connecting devices to your network, regardless of whether or not they're in the same room as your router.
It uses your home's mains power wires to create a network connection that - in many cases - is faster than Wi-Fi. It isn't limited to gadgets that have an Ethernet port: some powerline kits can create powerful new Wi-Fi hotspots to give you a wireless signal in rooms or areas your router can't reach.
It's simple, easy to set up, and inexpensive given that it will greatly improve your home network for streaming HD TV, gaming and other data-hungry devices and services.
The best Powerline adapters are a better bet than Wi-Fi extenders or repeaters that merely push a weak signal further around a house.
An interesting alternative is Mesh Wi-Fi (see our Best Mesh Wi-Fi Networks roundup), but Powerline is the fastest and can come with extra Wi-Fi hotspots built-in. Devolo's Magic WiFi range (see below) marries Powerline and Mesh technologies.
Here's how easy it is to install powerline adaptors. Plug one adapter into a power socket near your router and attach it to the router with an ethernet cable (usually supplied with the powerline kit- or check out the best ethernet cables in our separate roundup).
Then go to the room where you want to hook up a device to the network, plug the second adapter into a nearby power socket, and connect another ethernet cable from that to the device you want to get online.
That's it. It really is plug and play.
What if I need Wi-Fi?
As we've said, some Powerline adapters also have built-in Wi-Fi and create a new wireless network in that second room. This means you can get a strong, fast signal for your laptop, smartphone, tablet or another Wi-Fi gadget.
If you just want great Wi-Fi coverage across your entire home and not just a new hotspot in one weak room, then consider "Mesh"; read our roundup of the best Mesh Wi-Fi network kits. But Powerline with Wi-Fi is a simple solution that works very well - especially for smaller homes.
What other features should I look for?
You should also consider adapters that have an integrated "pass-through" power socket and therefore don't take up a valuable wall socket.
The cheapest powerline adapters are usually rated at 500Mbps (although these are pretty rare these days), and the fastest can go as high as 2,000Mbps.
You won't actually achieve these speeds as they're theoretical maximums, but they are an easy way to gauge which models are fastest.
Also look out for adapters that use the latest Gigabit Ethernet ports, if the adapters are rated at over 500Mbps this is a must, and most higher-rated Powerlines do include this fastest Ethernet standard. You nearly always get two Ethernet cables in a starter kit.
Tech Advisor tests powerline adapters in real-world environments so check out our list below for our performance results and recommendations, along with links to our full reviews for speed scores and feature explanations.
Some of the adapters we review here were tested a few of years ago, but the basic technology hasn't changed much and these are gadgets that you don't need to upgrade very often, making them even better value for money. The tech doesn't move quickly like smartphones.

Best Powerline adapters 2020
1. TP-Link AV1000 Gigabit Powerline
Best value, fast Powerline
The TP-Link AV1000 series of Powerline adapters is a well-made and fast set of data shifters at great prices. In some speed tests we actually found it faster than the supposedly more able TP-Link AV1200 adapters, so it punches above its weight. While in TP-Link's midrange, it offers great value at close-to-top speeds.
It’s available in four versions: the basic one-port TL-WPA7010 KIT, one-port TL-PA7010P KIT with pass-through power socket, TL-PA7020P KIT with pass-through socket and two Gigabit Ethernet ports, and the TL-WPA7510 KIT that can create a new, fast Wi-Fi hotspot in your home.
If you need it, the Wi-Fi model is well worth the extra cost, as are the models with pass-through sockets.

2. Devolo Magic 2 Wi-Fi
Best for speed, features and Mesh Wi-Fi capability
Devolo’s Magic Powerline & Mesh Wi-Fi system offers the best of both worlds in terms of home networking. Using the latest G.hn network standard, it has the potential to blow away other Powerline adapters, and with advanced Mesh capabilities (Fast Roaming, Band Steering, Config Sync, and Airtime Fairness) it should excel in larger homes that require more than one extra Wi-Fi hotspot.
Speeds are fast, but you're paying for Powerline and Mesh so this is best suited to homes that require more than one extra Wi-Fi hotspot. If you're after a fast Mesh system this one really delivers.
Smaller homes (where you don't need an extra Wi-Fi hotspot or just the one) might get much the same performance from cheaper non-Mesh Powerline-only systems, or the non-Wi-Fi Magic versions, such as the Magic 2 LAN.

3. TrendNet Powerline 500AV2 Adapter Kit
Best budget Powerline
This inexpensive kit is great value if you don't need the absolute fastest speeds possible, and the Wireless Access Point option adds fast Wi-Fi if you need more than simple wired network ports. Although you can buy 1,000Mbps and faster adapters, they won't double the speed of this 500Mbps set.
More than one port per adapter would have been nice, and the adaptors lack pass-through sockets, but at this price they're a great option for those on a limited budget.

4. TP-LINK AV1200 Gigabit Powerline Adapter
Best Powerline for multiple ports
The TP-Link AV1200 Gigabit Powerline Adapter Starter Kits (TL-PA8010 KIT, TL-PA8010P KIT, TL-PA8030P KIT, or TL-WPA8630P KIT) match their rival Gigabit Powerline adapter sets in our real-world speed tests. We prefer the only slightly more expensive TL-PA8030P as it boasts three Gigabit Ethernet ports, compared to the TL-PA8010P's single port adapters.
If your house suffers from weak Wi-Fi consider the WPA8630P that includes functionality to add a new Wi-Fi hotspot in your house. If your Wi-Fi signal is acceptable you can live without a new hotspot, and the TL-PA8030P especially represents great Powerline value.

5. Devolo 1200+ Powerline Adapter
Best value Powerline with 2 ports, pass-through and Wi-Fi
The Devolo dLan 1200+ is one of the fastest Powerline adapters we’ve tested. It might not reach the dizzying speeds that it claims, but that’s true of all Powerline adapters out there. Its integrated electrical pass-through power socket is a real bonus, and the model with Wi-Fi and two Gigabit Ethernet ports on the second unit pretty much has it all. It's not the very latest model but it still performs excellently. (Not available in the US.)

6. TP-Link AV2000 2-Port Gigabit Passthrough Powerline
We were impressed by the real-world performance of the TP-Link AV2000, which scored as high as we’ve seen in our tests. The inclusion of pass-through sockets on the TL-PA9020P KIT version and two Gigabit Ethernet ports per adapter (on both the TL-PA9020P KIT and TL-PA9020 KIT) are also welcomed. There’s no extra Wi-Fi hotspot function but if your house Wi-Fi is acceptable this isn’t the worst omission. If you want a fast Powerline starter kit with more than one Ethernet port plus pass-through this is highly recommended, and is at decent price too.
7. Netgear PowerLINE WiFi 1000
The Netgear PowerLINE WiFi 1000 lacks multiple Ethernet ports on each adapter and doesn’t have handy pass-through power sockets. But it performed well in our real-world speed tests, especially with its second-room new WiFi hotspot. The base unit is nicely compact, and the second adapter looks the part with its two antennae.
The price is reasonable for a Powerline with extra WiFi, but you can get cheaper Powerline. If you don’t need more than one Ethernet port per adapter but do want to improve your house Wi-Fi speeds the Netgear PowerLINE WiFi 1000 is certainly worth considering.

9. Trendnet Powerline 1200 AV2 Adapter Kit (TPL-420E2K, TPL-421E2K)
Powerlines create fast home networks with the minimum of fuss, and the Trendnet Powerline 1200 AV2 Adapter Kit is one of the fastest we’ve tested. It is rather limited by its no-frills features, though: one Ethernet port per adapter and lack of wireless, but if you want just the basics at top speeds you will surely love this Powerline kit.
It is available in two models: the entry-level TPL-420E2K, and the slightly larger TPL-421E2K, which features the handy pass-through sockets on each adapter.
