If weak Wi-Fi affects several rooms or floors, assess a mesh system; for one weak room with a usable signal between it and the router, an extender may be enough. Powerline is worth considering where walls obstruct a wireless link and the electrical setup is suitable, while a cable-fed access point suits a fixed room; replace the router if the existing unit itself is the limitation. Compare a wired connection at the router with Wi-Fi in the affected rooms first: as Ofcom explains, better in-home Wi-Fi cannot make the underlying broadband service faster.
Who these options suit
Households with several weak rooms
If calls, streaming or connected devices lose Wi-Fi across floors, consider where multiple nodes could sit and whether they can maintain a connection to one another. A single extender aimed at one room may leave other gaps untouched.
Households with one dead zone
For one weak bedroom, study or TV room, an extender is worth assessing if it can receive a usable router signal partway to that room. Where the wireless path is obstructed, the home’s electrical wiring may offer another route.
People using one fixed room
A desk, console or TV that stays in one place creates a different decision from coverage while moving around the house. Check whether Ethernet can reach the device or feed an access point in that room.
What matters when choosing
For a home where broadband reaches the property but Wi-Fi varies by room, identify the main coverage problem before choosing equipment. Check the incoming connection separately so a broadband fault is not mistaken for a room-by-room Wi-Fi gap.
| Concern | What to check | Who this matters to |
| Several weak rooms |
Count the affected rooms and floors; plan viable mesh-node positions and check whether a wired connection between nodes is possible. |
If I move between floors for calls or streaming, fixing one room still leaves other gaps. About 30% of consumers put coverage across several rooms first. |
| One reachable dead zone |
Find a powered position between the router and weak room that still receives usable Wi-Fi, as TP-Link advises for its extenders. |
When just one room loses signal, I want to reach it without changing the network throughout the house; roughly 20% of consumers prioritise that single-room need. |
| Walls or difficult floors |
Check the intended sockets and electrical arrangement before choosing powerline; TP-Link specifies a same-circuit requirement for its adapters. |
If thick walls block the wireless path and I cannot run a long cable, I need another way into the room. For about 20% of consumers, getting around that barrier is the primary concern. |
| One fixed work or media room |
Check whether Ethernet can reach the device or a local access point, and whether the chosen equipment needs a compatible power source. |
At a desk or TV that stays put, I care more about the connection in that room than roaming between rooms; around 20% of consumers put fixed-room reliability first. |
| The main router |
Assess frequent disconnections and the router’s compatibility with the broadband service before replacing it. |
If Wi-Fi is troublesome near an ageing router too, adding a distant node may miss the issue. About 10% of consumers primarily need to assess the main router. |
Mistakes to avoid
-
Buying coverage equipment before checking the connection
A poor Wi-Fi result in one room does not establish a broadband fault, but equipment for extending coverage will not fix a slow incoming connection. Ofcom notes that Wi-Fi cannot outperform the broadband service.
Where possible, compare a device connected to the router by Ethernet with Wi-Fi in the affected rooms, and check for provider faults if the wired result is poor too.
-
Putting an extender inside the dead zone
An extender must receive a usable router signal before it can relay it. A socket in the room with no usable signal may therefore be the wrong position.
TP-Link advises placing an extender roughly halfway to the weak area. If no suitable midpoint exists, assess another node position, powerline or a cable-fed connection.
-
Assuming powerline will work equally well in every home
Powerline uses the property’s electrical wiring, so the intended sockets and installation matter. TP-Link states a same-circuit requirement for its adapters.
Check the socket and circuit arrangement for the specific kit before buying, then test it in the rooms where it will be used.
-
Assuming mesh-labelled devices will work together
Mesh families and backhaul features are model-specific. TP-Link says its Deco Mesh and OneMesh devices cannot simply be combined into one mesh, and EasyMesh Ethernet backhaul requires support at both ends.
Check the complete model numbers, hardware revisions, firmware and intended wired or wireless connection before adding equipment to an existing network.
Brands to consider
TP-Link
Its home-networking range includes Deco mesh systems, extenders and powerline adapters, giving buyers several distinct routes to assess.
- TP-Link provides placement guidance for extenders and compatibility information for its mesh families.
- OneMesh, EasyMesh and Deco compatibility cannot be assumed across models; check firmware and backhaul support for the devices you intend to combine.
eero
Amazon’s UK eero store presents the range as multi-node mesh Wi-Fi for home coverage.
- A mesh range to assess when the purchase question is coverage across several rooms rather than one isolated gap.
- Check the particular kit’s unit count, Ethernet connections and any optional service terms against your intended setup.
devolo
Its Magic range uses electrical wiring to carry a network connection and includes powerline Wi-Fi options, according to devolo.
- A route to assess when walls make a wireless link difficult and running Ethernet is impractical.
- Results depend on the electrical installation; test the intended socket locations rather than relying on a stated product speed.
Ubiquiti
Its access-point range is relevant when Ethernet can feed Wi-Fi equipment near the room needing coverage.
- A cable-fed access point can address coverage in a chosen location without relying on a wireless relay to the main router.
- Plan the cable route and check the chosen model’s power requirements, including whether compatible Power over Ethernet equipment is needed.

TP-Link RE220BE BE3600 Wi-Fi 7 range extender
Consider this extender for one weak room if a suitable position between that room and the router still receives usable Wi-Fi. Without that position, repeating the wireless signal may not address the gap.
Check the exact router model before relying on EasyMesh features.

Common questions
Is poor Wi-Fi in one room a broadband problem?
Not necessarily. Compare a device connected to the router by Ethernet, where possible, with Wi-Fi tests near the router and in the weak room. Ofcom distinguishes Wi-Fi problems from faults with the broadband connection; if the wired connection is poor too, investigate the service before buying coverage equipment.
Where should I put a Wi-Fi extender?
Place it where it can still receive a usable signal from the router, roughly halfway towards the weak area, as TP-Link advises. A socket deep inside a dead zone is unlikely to give it a workable signal to relay.
Will devices from different mesh ranges form one network?
Do not assume they will. TP-Link says its Deco Mesh and OneMesh devices cannot be combined into one mesh, while support for other combinations and Ethernet backhaul depends on the specific devices. Check both model numbers, hardware revisions and firmware before buying an add-on unit.
