Name: TP-Link Deco X50 (3-pack)
Brand: TP-Link

Our verdict

The TP-Link Deco X50 is a mesh Wi-Fi system: three matching units placed around your home work together as one Wi-Fi network, so rooms far from your router can get a stronger signal. It uses dual-band Wi-Fi 6. Its AX3000 label adds up the maximum link speeds of its two bands (2,402Mbps plus 574Mbps); it is not a promise of 3Gbps internet, and your broadband speed stays the same. Each unit has three Gigabit Ethernet ports for wired devices such as a TV or desktop computer. It plugs into your existing broadband equipment rather than replacing it. Its launch price was about £290, though retailers often sell it for less. We have not installed it ourselves.

Buy it if

Upstairs or distant rooms have weak Wi-Fi, and your broadband is fine near the router
You want wired connections for a TV or computer away from the router
You can place the units sensibly around the home, or run cables between them

Skip it if

Your home is small and already well covered
Your broadband is slow even next to the router
You need wired speeds faster than Gigabit

Everyday use

Weak Wi-Fi upstairs

Placing one unit near the router and others between it and the problem rooms is the main job a mesh system does.

A study computer or TV away from the router

Plug it into a nearby Deco unit’s Ethernet port for a wired connection, without running a cable back to the router.

Smart devices around the house

Smart plugs, speakers and cameras in far rooms need a usable signal too, and a mesh system can reach them where the router does not.

The details, in plain English

First, check the problem is Wi-Fi

Mesh fixes weak coverage. It cannot make the broadband coming into your home any faster. If your broadband is slow even next to the router, mesh will not fix it. GBAtemp tested a three-pack on a slow broadband connection: in the weak room, laptop speed improved from 2.70Mbps to 3.62Mbps and phone speed from 2.58Mbps to 3.84Mbps. Coverage improved, but speeds could never exceed the broadband itself.

Wi-Fi 6 and what AX3000 means

Dual-band means the units use the 2.4GHz and 5GHz bands, so devices and the link between units share the same airwaves. AX3000 adds up the maximum link speeds of both bands; it is not an internet speed. Expert Reviews tested three units in 2022 and found the Linksys Atlas Pro 6 averaged about 35% faster downloads in that home. It called the X50 competent but poor value at the then price of £290.

Wired ports and backhaul

Each unit has three Gigabit Ethernet ports, which carry up to 1Gbps over a cable. Argos lists 2.5Gbps ports, but TP-Link’s official specifications say Gigabit, so go by TP-Link. If you can run Ethernet cables between the units, known as Ethernet backhaul, they talk to each other over the cable and leave the Wi-Fi free for your devices.

Setting it up

You set up and manage the system through the Deco app. It can work in router mode or access-point mode, and which you need depends on your existing broadband router, so allow time to get that right and reconnect your household devices. Each unit needs a power socket, and where you place the units matters. GBAtemp found repeated firmware-update prompts awkward, though current firmware may behave differently.

Subscriptions, updates and versions

Core Wi-Fi works without a subscription. App-based blocking and time limits for children are part of TP-Link’s paid Advanced Parental Controls (HomeShield Pro); check the current fee in the app. The Deco X50 has several hardware versions. TP-Link’s UK support page listed firmware for version 3 on 28 September 2026, which shows the product is still supported. TP-Link’s current specifications list VPN features that Expert Reviews found missing in 2022, but check they apply to your version.

Strengths and drawbacks

What it does well

Three units can carry a stronger Wi-Fi signal to rooms your router misses
Three Gigabit Ethernet ports on each unit for TVs and desktop computers
Ethernet backhaul: cable the units together so they do not share Wi-Fi capacity
Core Wi-Fi needs no subscription, and TP-Link is still publishing firmware updates

What to watch out for

Dual-band only, so it has less wireless capacity than suitable higher-end systems
It will not make slow broadband any faster
Three units need three power sockets and sensible placement
App-based blocking and time limits for children need a paid subscription

TP-Link’s Deco XE75 adds a third Wi-Fi band at 6GHz (Wi-Fi 6E), which only helps devices that support it. In Expert Reviews’ 2022 test, the Linksys Atlas Pro 6 downloaded faster; check it is still sold in the UK before considering it. For a smaller home with one weak room, moving your router or adding a single wired access point may be a cheaper fix. We have not tested these alternatives side by side.

Where our findings come from

This review is based on TP-Link’s UK product, support and download pages, the Argos, Select and PCBoost listings, and hands-on three-unit tests by Expert Reviews (Darien Graham-Smith, April 2022) and GBAtemp (Prans, 2022). Their results are credited to them in the text. Neither review states the hardware version tested, and GBAtemp’s slow broadband means its results show coverage, not fast-fibre performance. Prices were checked on 4 October 2026.
