Mesh Wi-Fi systems may sound complicated, but they're really easy to install and they will instantly solve your Wi-Fi woes. No more weak signals or dead zones, and they don't have to cost a lot either.

Although they're called routers - which they are - they typically work alongside your existing router, and it's a good idea to turn off its Wi-Fi so it doesn't interfere with the new system.

Here we’ve reviewed and ranked all the latest systems for all budgets.

Best mesh Wi-Fi systems for 2021

1. TP-Link Deco P9 - Best Overall

  • Rating: ratingsratingsratingsratingsratings

It's easy to set up, has a well-designed and feature-packed app and offers great performance, so it’s tough to fault TP-Link’s Deco P9 mesh Wi-Fi system. While it was originally available in a set of three with a 6000 square foot range, TP-Link has since launched a twin set ideal for smaller homes.

Unlike other systems here, the Deco P9 uses hybrid connectivity: a combination of mesh Wi-Fi and powerline networking which helps to provide a reliable connection even through thick walls.

If you want a no-fuss mesh Wi-Fi system that works well, the Deco P9 system won’t disappoint.

2. Nighthawk Mesh WiFi 6 System - Best-value Wi-Fi 6

Netgear Nighthawk Mesh WiFi 6 System
  • Rating: ratingsratingsratingsratingsratings

The Nighthawk Mesh WiFi 6 System is the cheapest Wi-Fi 6 ready system going so far, is simple to set up and use, and its reach can be expanded easily, by adding more satellites.

It’s not without its drawbacks; the lack of a third wireless channel for backhaul and limited range means it’s nowhere near as powerful at Netgear’s own Orbi devices, but then again, it’s priced very competitively. Some users will find the lack of ports limiting, but then again, you can always invest in a network switch.

Otherwise, the Nighthawk Mesh WiFi 6 System represents an easy and inexpensive way to pipe Wi-Fi 6 around your home.

3. Linksys Velop Dual Band - Best dual-band system

Linksys Velop Dual Band
  • Rating: ratingsratingsratingsratingsratings

Although the app and setup process could be better, we really have no complaints about the Linksys Velop kit.

Via the app you can manage the network, enable guest Wi-Fi and create basic access rules to limit internet time for specific devices. 

This dual-band system provides a reliable wireless network with decent speeds that should satisfy most families. Importantly, it's far more affordable than the pricey tri-band version of the Velop.

4. Tenda Nova MW3 - Cheapest mesh Wi-Fi

Tenda Nova MW3
  • Rating: ratingsratingsratingsratingsratings

The MW3 is the cheapest mesh networking system we've reviewed. It has dropped in price since it was launched, making it a very tempting option for those on a budget.

As you'd expect, it can't match the performance of its more expensive rivals, but it still does a great job of delivering a strong Wi-Fi connection and eliminating dead zones around your home.

That makes it a terrific bargain if you just need to provide a good internet connection around an average-size home, rather than have the ultimate Wi-Fi speeds.

5. TP-Link Deco M5 - Best value

  • Rating: ratingsratingsratingsratingsratings

We can’t fault the Deco M5's performance and ease of use, and the coverage is also impressive considering the price. You also get an antivirus subscription bundled which is a bonus.

The app offers parental controls, though not the most granular control, and also lets you create a guest Wi-Fi network.

If you’re looking for a mesh networking kit that's not too expensive and which can provide a fast, reliable Wi-Fi signal throughout your home, then the Deco will really earn its keep.

6. Google Nest WiFi - Mesh with built-in smart speaker

Google Nest Wifi
  • Rating: ratingsratingsratingsratingsratings

The latest version of Google's mesh Wi-Fi system has evolved quite considerably. The main unit (and additional 'points') are also smart speakers with the Google Assistant, so this mesh system will save you if you were planning to buy one or more Google Nest speakers, along with using fewer mains outlets and you have fewer devices littered around your home.

The kit doesn't support the latest Wi-Fi 6 standard, which you might expect at this price, but Nest WiFi is plenty fast enough for the average home and will improve signal around even smaller house vs a regular router.

Of course, you also get great Google software which makes the whole process simple and easy to use. Not only it is a breeze to get set up, but the features are accessible and helpful including a guest network, priority devices and parental controls. You can even pause the network with your voice via the Google Assistant.

7. Amazon Eero

  • Rating: ratingsratingsratingsratingsratings

The Eero system is simple, elegant and works well. It's also easy to set up and monitor using the companion app.

Wireless speeds are respectable, though if you want something a little faster, then a tri-band Eero Pro system might be just the ticket.

Gamers, home office workers or anyone with a lot of devices that work better with a wired connection will find the two Ethernet ports per Eero limiting, but most users will be happy with the wide-ranging wireless coverage (and you can always buy an inexpensive Ethernet hub if you do need more wired ports).

8. Tenda Nova MW5 - Great value mesh Wi-Fi

Tenda Nova MW5
  • Rating: ratingsratingsratingsratingsratings

Even though it's better specified than the MW3, the MW5 is still very affordable. It isn't the last word in speed or coverage, but it isn't meant to be: it's designed for smaller homes and people with smaller budgets.

And it succeeds in its goal admirably, and is the ideal upgrade if you're getting by with the Wi-Fi from your ISP-supplied router.

9. Devolo Magic Powerline & Mesh Wi-Fi kit - Powerful Hybrid Mesh

Devolo Magic 2 Wi-Fi Next
  • Rating: ratingsratingsratingsratingsratings

The Devolo Magic Powerline & Mesh Wi-Fi kit offers the best of both worlds in terms of home networking. Using the latest network standard, it has the potential to outperform other powerline adapters, and with it's solid mesh Wi-Fi performance it should excel in larger homes that require more than one extra Wi-Fi hotspot.

With powerline tech, mesh Wi-Fi, pass-through sockets and two Ethernet ports, the Magic 2 is loaded with features.

Speeds are fast, but you do pay for them: this isn't the cheapest option by any stretch. However, if you're after a fast Mesh system for a larger home, 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.

What's the best mesh Wi-Fi network you can buy?

Put simply, a mesh network is two or more Wi-Fi routers which work together to provide much wider Wi-Fi coverage than a single router can. This gives you a single Wi-Fi network even though in the background your devices will seamlessly connect and disconnect from individual routers in the background as you move around.

Some kits have just two units and can’t be expanded, while others can be bought in one, two or three-packs and allow you to add extra coverage when you can afford it or when you need it.

Best Mesh Wi-Fi Network

Does it replace my existing router?

No. It’s best to think of mesh system as a replacement for your existing router’s Wi-Fi. You attach one of the devices from a mesh Wi-Fi kit to a spare network port on your router and it creates a new Wi-Fi network to which all your phones, computers, tablets and Wi-Fi smart home gadgets connect.

You then place the second (and third if relevant) mesh device somewhere else in your house, typically on another floor.

The devices all talk to each other and create a single Wi-Fi network that’s both strong and fast across your entire home.

The only reason you may find you still don't get whole-home coverage is if a) you have an extremely large home or b) your home has very thick stone, brick or concrete walls. Our reviews are based on a typical three- to four bedroom UK home.

If you suspect that a Wi-Fi mesh system won't work in your home due to its construction, note that our number-one choice - the TP-Link Deco P9 - uses powerline networking as well as Wi-Fi, so the units can talk to each other using your home's electrical wiring, meaning thick stone walls aren't an issue.

Devolo's Magic 2 Wi-Fi works in a similar way, connecting its Wi-Fi hotspots using powerline networking.

Don't confuse these with traditional powerline adapters with built-in Wi-Fi.

Are powerline adapters a cheaper alternative, though?

Yes. If you just need to get a Wi-Fi signal in one room that your current router can’t reach, you might be able to save money by buying the type of Wi-Fi-enabled powerline kit that we've just mentioned.

Check out our roundup of the best powerline adapters for more, but bear in mind that not all powerline kits include Wi-Fi, so cheaper kits will only connect gadgets that have an Ethernet port.

What other benefits do mesh Wi-Fi systems offer?

They’re usually controlled via an app. In some cases this exists mainly just to help you install the system in the first place, but it can also be used to monitor which devices are connected to which hub.

Some apps also let you ‘pause’ the Wi-Fi network but the best let you stop Wi-Fi on certain devices, so you could prevent your kids watching more YouTube videos, for example.

Others include parental controls or scheduling so Wi-Fi is only available at certain times or to certain devices.

Anything else to watch out for?

Yes. Some mesh systems (but not all) prevent Wi-Fi devices from talking to other gadgets that are connected to your main router’s wired network ports. That's because they don't support Bridge mode.

For example, you might find you can’t print from your PC as your printer is connected to the Wi-Fi network but your PC is connected via a network cable to your old router.

Mesh Wi-Fi is a smart solution, but there may well be other ways to speed up your home network.
