If Wi-Fi works near the router but fails in one distant room, consider an extender positioned where it can still receive a usable signal. For several weak rooms or floors, consider mesh; where construction obstructs wireless links, powerline may help if the intended sockets share an electrical circuit. If the connection is poor even beside the router, check the broadband service and existing router before buying coverage equipment.
If Wi-Fi is adequate near the router but fails in one room, check whether there is a suitable spot between the two for an extender. TP-Link advises placing an extender where it can still receive the router's signal; a whole-home system need not be the starting point for one reachable area.
When several rooms or floors have weak coverage, mesh offers multiple nodes under one network. Node positions still matter: thick walls or floors may make a wired or powerline-assisted connection between nodes worth considering.
If several people work, stream or game at once, compare performance near the router with performance in distant rooms. Ofcom notes that Wi-Fi cannot outperform the underlying broadband service, so additional coverage equipment will not resolve every slowdown.
Start by locating the problem: one weak room points to a different purchase from several weak floors, while poor performance close to the router calls for service and router checks first. The priorities below help narrow the equipment choice.
| Concern | What to check | Who this matters to |
|---|---|---|
| Several weak rooms or floors | Map the weak areas and identify powered mesh-node locations. Check whether walls or distance make wired or powerline-assisted links between nodes necessary. | When several distant rooms lose Wi-Fi, I need coverage that lets me move around the home without changing networks; around 33% of consumers put whole-home coverage first. |
| One reachable dead zone | Check for a usable router signal between the router and the weak room, and confirm the extender can connect to the existing router. | If only my study has weak Wi-Fi, I want to address that room while keeping an otherwise adequate router; roughly 27% of consumers make a single dead zone their main concern. |
| Obstructive walls or floors | For powerline, confirm that the intended sockets share an electrical circuit. Otherwise, assess feasible mesh-node or Ethernet locations. | Where thick construction makes a wireless link between rooms unreliable, I need another viable route through the home; around 20% of consumers prioritise this connection problem. |
| Poor performance near the router | Check for provider faults, compare devices and times of day, and confirm broadband-equipment compatibility before replacing a router. | If several devices struggle even close to the router, I need to distinguish a service fault from a router problem; about 20% of consumers put that decision first. |
An extender or mesh system cannot speed up a slow broadband service. Ofcom also identifies outages, device issues and simultaneous use as possible causes of connection problems.
Compare performance near the router and in the weak room at different times, check the provider's service status and report persistent faults before purchasing.
An extender needs a usable upstream signal before it can repeat the connection into the weak area.
Start at a point between the router and the target room, then use the extender's placement guidance to adjust its position.
TP-Link's guidance says its powerline adaptors must be on the same electrical circuit. Rooms within one property should not be assumed to meet that condition.
Confirm the circuit arrangement for the intended sockets before choosing powerline; otherwise assess wireless mesh-node or Ethernet placement.
A third-party router may take more work to configure, and the broadband provider may offer less help diagnosing problems involving it.
Check the connection type, modem or fibre ONT arrangement, required provider settings and available support before ordering.
Its range includes targeted extenders, powerline adaptors and Deco mesh systems.
Its Orbi range is relevant to households considering multi-node mesh.
AiMesh is an option to investigate if you already own an ASUS router.
Its Complete Wi-Fi route is relevant to BT broadband customers considering provider-supplied equipment.
These products cover multi-room mesh, a powerline Wi-Fi kit and a targeted extender. Choose the approach according to where the connection fails; check installation conditions and broadband-equipment compatibility for the individual model.

A three-unit mesh option to consider when several rooms need Wi-Fi coverage.
The product name specifies tri-band Wi-Fi 7 and a 3-pack. Check suitable node positions and compatibility with your broadband equipment before buying; coverage in a particular home depends on its layout.
No image available
A three-unit mesh option for a home with several areas needing coverage.
The product name specifies dual-band WiFi 7, BE3600 and 2.5Gbps Ethernet. Check how it connects to your existing modem or gateway and whether the node locations suit your home.
No image available
A powerline Wi-Fi kit to consider where walls or floors make a wireless link between rooms difficult.
The product name identifies an AV1300 Gigabit kit. Confirm that the intended sockets share an electrical circuit; do not treat the stated link rate as throughput guaranteed in your home.
No image available
A three-unit mesh option to assess for weak coverage across multiple rooms.
The product name specifies BE3600 Wi-Fi 7 and a 3-pack. Check where the units can be placed and whether your layout permits a suitable connection between them.
No image available
An extender to consider when one weak area has a suitable installation point within reach of the existing router.
The product name specifies BE3600 Wi-Fi 7. Check the signal at the proposed location before buying; if you want EasyMesh roaming, also check router compatibility.
Compare the connection close to the router and in the weak room, then repeat the check at different times and on different devices. If it is poor near the router too, check the provider's service status and report a persistent fault before assuming an extender or mesh system will help. Ofcom notes that Wi-Fi cannot outperform the broadband service.
Put it between the router and the weak area, where it can still receive a usable router signal. TP-Link advises against installing an extender inside the dead zone; use the model's placement guidance to refine the position.
Do not assume they will. TP-Link specifies that its powerline adaptors must be on the same electrical circuit, so confirm the intended sockets meet that requirement before choosing a kit, particularly in an extended or converted home.
You can consider a third-party router, but first confirm that it works with your broadband connection, modem or fibre ONT and required provider settings. Ofcom notes that third-party equipment can be harder to set up and that the provider may be less able to help with problems involving it.
Check who provides support for the exact model and what the warranty documentation covers. Citizens Advice advises checking its duration and the remedies stated in the paperwork; a voluntary warranty does not replace legal rights.
