For one weak room, assess an extender if it can sit where the router signal is still usable; for weak coverage across several rooms or floors, assess mesh. Powerline is an option where a wireless relay is difficult and the intended sockets share an electrical circuit, while a new router is worth considering if the primary router struggles with the household’s devices. Check the incoming broadband service and your provider-router setup before changing equipment.
The number of affected rooms matters more than the size of the coverage claim on a box.
If most rooms work acceptably but one bedroom, corner or nearby outdoor area does not, assess an extender first. Which? describes an extender as a way to reach a particular targeted area; it still needs a usable signal where you place it.
When coverage is unreliable across rooms or floors, consider where mesh nodes could connect to one another and how the network will connect to your existing router. If streaming, gaming and work calls also struggle when several people are online, check the broadband service and primary router rather than assuming coverage is the only problem.
If a broadband-provider router or connected TV equipment needs to stay, check whether the proposed kit can work alongside it and which device will manage the network. For a room separated by walls or floors, powerline is another route to assess—but TP-Link says both adaptors must be on the same electrical circuit.
Map the weak areas, check the connection near the router, then look at the installation conditions for the route that fits your home.
| Priority | What to check | Your needs |
|---|---|---|
| Coverage pattern | Note which rooms or floors are weak. For one targeted area, check whether an extender can receive a usable router signal between the router and that area. For several areas, plan where mesh nodes could go. Which? distinguishes targeted extender coverage from wider mesh coverage. | Only one room loses signal, or do I need dependable Wi-Fi in several places as I move around the home? |
| Incoming connection | Check whether problems persist close to the router, whether the provider reports a fault, and whether heavy use by other devices coincides with slowdowns. Ofcom notes that Wi-Fi cannot outperform the broadband service arriving at the home. | If the connection is slow even beside the router, I want to identify that cause before buying equipment to extend its reach. |
| Several active devices | Consider whether the primary router struggles when devices are used together, as well as whether individual rooms have weak signal. Ofcom advises checking for other people doing data-heavy tasks on the network. | Work calls, streaming and gaming may overlap in my household; I need to know whether coverage, the router or the broadband connection is the constraint. |
| Walls and wiring | If a wireless relay would cross difficult obstacles, assess powerline using the sockets you intend to use. TP-Link says both adaptors must share an electrical circuit; a multi-storey layout alone does not establish that they do. | A distant room is hard to reach wirelessly, and I can check the intended sockets before relying on powerline. |
| Provider setup | Check whether new kit will extend the existing Wi-Fi, use access-point mode or take over routing. TP-Link documents access-point mode for adding Deco mesh while retaining an existing router; confirm the exact equipment, connection and provider-dependent services. | I need my broadband-provider equipment or connected services to keep working after the network changes. |
An extender targets an existing signal towards a particular area. Which? distinguishes that use from a mesh system intended for wider coverage, so adding one extender need not address separate weak areas.
Check signal room by room. If the problem spans several rooms or floors, assess a mesh layout rather than judging an extender by its advertised range alone.
The extender needs a viable connection back to the router; a position where the router signal is already too weak undermines that link.
Try a position between the router and weak area where the router signal remains usable, then check the connection in the room you want to serve.
TP-Link says both powerline adaptors must be on the same electrical circuit. Being in the same home is not enough to establish that the intended sockets meet this condition.
Identify the sockets at both ends and confirm the circuit arrangement before choosing a powerline kit.
A different router or operating mode may require connected equipment to be set up again. Virgin Media describes modem mode as a way to connect your own Wi-Fi kit, while Sky provides separate instructions for connecting a Sky Q box to a non-Sky router.
List the services and devices that use the current router, then check the provider’s instructions for your exact equipment before changing modes or hardware.
Allow time to reconnect devices and check which existing router functions will remain available.
These ranges illustrate different equipment routes; the suitability of a particular model still depends on your router, layout and installation.
TP-Link has extender, Deco mesh and powerline ranges relevant to targeted and multi-room coverage.
ASUS AiMesh is relevant if you are considering compatible ASUS routers as parts of one home network.
The Orbi range is a dedicated mesh route with router-and-satellite arrangements.
These options cover multi-room mesh systems, a powerline kit for a suitable electrical circuit and an extender for a targeted weak area. Choose the route for the rooms affected, then check how the specific kit connects to your existing network.

A three-pack mesh option to consider when coverage is weak across several rooms. Check how this exact system would connect to your broadband-provider router and where its units could be placed; stated coverage and speed are not results for your home.

This three-pack mesh system is an option for several affected rooms. Check its connection requirements against your existing modem or gateway and plan unit placement; building materials and network conditions can affect coverage.

Consider this three-pack where several parts of the home need Wi-Fi coverage. Confirm the connection and operating mode needed with your provider router, including any provider-specific functions you want to retain.

A powerline route to assess for a remote room where a wireless relay is difficult. TP-Link says both adaptors must use the same electrical circuit; confirm the intended sockets and check router compatibility before relying on any OneMesh function.

An extender option for one targeted weak area rather than a plan for several separate dead zones. Choose a position that still receives a usable router signal, and check your exact router before relying on EasyMesh compatibility.
Assess an extender if that is the only weak area and it can be placed where the router signal remains usable. If several rooms or floors are affected, assess mesh node placement instead; Which? distinguishes an extender’s targeted reach from wider mesh coverage.
No. An extender can help Wi-Fi reach a weak area, but it cannot increase the incoming broadband speed. Ofcom says Wi-Fi cannot outperform the broadband service, and Sky makes the same distinction between improved coverage and speed to its hub.
That is possible with a suitable setup: TP-Link documents access-point mode for adding Deco mesh while retaining an existing router. Check the exact mesh model, its required connection and which network functions your provider router must keep.
Plan to reconnect the Sky Q box rather than assuming it will move to the new Wi-Fi automatically. Sky’s instructions cover resetting its network connection and selecting Wi-Fi from another broadband provider; check the steps for your box and setup.
Compare the connection near the router with the affected rooms, check for a provider fault and note whether slowdowns coincide with data-heavy use by other people. Ofcom advises checking those household demands and notes that even good Wi-Fi cannot exceed the underlying broadband service.
