First check whether the broadband service or the connection inside your home is limiting your activities: as Ofcom explains, better Wi-Fi cannot outperform the service reaching the router. A router replacement may suit a compact home with adequate coverage, while mesh addresses recurring gaps across several rooms, an extender targets one reachable weak area, and Ethernet is worth considering for fixed devices. Powerline is an option when running a cable is impractical, but its suitability depends on the home’s electrical wiring.
If calls, streaming, gaming and work overlap, compare a wired connection with Wi-Fi before buying more coverage equipment. Ofcom identifies both in-home congestion and device limitations as factors that can affect broadband performance.
Check where the signal weakens and whether a suitably placed extender could still receive it. For recurring gaps in several areas, consider where mesh units could be positioned or connected by cable.
A computer or console that stays in one place is a candidate for a direct cable connection. Ofcom advises using Ethernet to connect a computer to the router for the strongest broadband-speed result.
Start at the router, then identify whether the problem follows a particular room, device or period of simultaneous use. That helps narrow the choice before comparing equipment.
| Priority | What to check | Your needs |
|---|---|---|
| Find the bottleneck | Compare performance near the router and, where possible, over Ethernet at the same time. Check whether the problem also affects that wired device; Ofcom notes that Wi-Fi cannot outperform the broadband service. | I want to know whether changing the home network will address the problem before buying more Wi-Fi equipment. |
| Router-only change | Assess the current router and where it can be placed. A replacement still broadcasts from one location, so check for persistent distant-room gaps before relying on this route. | Coverage is already usable around my compact home, but I need to assess whether the existing router meets our connection needs. |
| Rooms with weak signal | Map the affected rooms and floors. Consider mesh for recurring gaps in several areas; for one weak area, an extender needs a location where it can receive the existing signal. Which? identifies both mesh and extenders as options when a router does not reach the far parts of a home. | Calls or browsing need to remain usable away from the router, rather than only in the room beside it. |
| Fixed priority devices | Check cable routes and available router ports; consider a suitable switch if several fixed devices need ports. Ofcom recommends a direct Ethernet connection for a computer when broadband speed matters. | Our work computer, console or streaming device stays in one place, and a cable may be practical. |
| Connection without new cabling | For a fixed room that cannot readily be reached by Ethernet cable, check for suitable mains locations and whether a powerline kit provides the type of connection the device needs. Its link depends on the home’s electrical wiring. | Running a network cable through the home is impractical, but the remote device still needs a connection. |
A new mesh kit or extender cannot raise Wi-Fi performance beyond the broadband service reaching the router. Ofcom also identifies in-home congestion, devices and content servers as possible influences on the experience.
Compare a device near the router with an Ethernet-connected device where possible. If the wired connection also struggles, investigate the service, router setup and device before adding coverage equipment.
An extender depends on a usable connection to the main router; one add-on may not address weak coverage in several rooms.
Check router placement first, then identify a position that receives the existing signal. Consider mesh or a cabled connection for recurring gaps across multiple areas.
Wireless conditions can affect a fixed work or gaming setup even when the broadband service is adequate. Ofcom recommends direct Ethernet for a computer when seeking the strongest broadband-speed result.
Check whether priority devices can reach the router by cable and whether a switch is needed for additional connections.
Rooms, floors, obstacles and equipment placement affect the signal path, so a model’s stated coverage does not guarantee the same result throughout a particular home.
Note which rooms have problems before choosing a kit, and check whether its units can be positioned or connected by Ethernet where needed.
TP-Link’s Deco range includes multi-unit home mesh systems.
eero offers mesh-capable products, including eero 7.
NETGEAR’s Orbi range offers multi-unit home mesh systems.
These options cover multi-unit mesh systems for recurring room-to-room coverage gaps and a powerline kit for a remote wired device. Diagnose the connection problem first: neither type replaces the need to check the broadband service.

Consider this three-unit system for coverage problems in several areas, subject to suitable placement. Its stated configuration is dual-band BE3600 with 2.5Gbps Ethernet; check the connections needed by your fixed devices and the supplied power equipment before buying.

Three mesh units provide a configuration to consider when weak coverage affects several rooms. Check where each unit could go, along with the exact pack contents, setup requirements and supplied power equipment.

This three-pack is an option for recurring weak areas beyond the router’s room. Plan unit positions around the actual layout; if fixed devices need wired connections, check the ports and supplied power equipment before buying.

Consider the three-unit layout if several rooms have recurring coverage gaps. Check positions for the units and the Ethernet port count if you intend to connect fixed devices; also confirm the supplied power equipment.

Consider this powerline kit for a remote wired device when running Ethernet cable is impractical. It uses the home’s electrical wiring rather than extending Wi-Fi coverage; check the required connection, mains locations and supplied power equipment before buying.
Compare a device near the router with one connected by Ethernet where possible. Ofcom says Wi-Fi cannot outperform the broadband service; if the wired device also struggles, check the service, router setup, device and activity before treating a distant-room signal gap as the cause.
Consider mesh when weak coverage recurs across several rooms or floors. For one weak area, an extender is an option only if it can receive a usable signal from the router at a practical location. Which? identifies both approaches for reaching parts of a home that the router does not serve reliably.
If cabling is practical, check a direct Ethernet connection for a stationary priority device before buying additional Wi-Fi equipment. Ofcom advises connecting a computer directly to the router by Ethernet for the strongest broadband-speed result.
Powerline offers a different route to a fixed room when running a direct cable is impractical: its adapters use the home’s electrical wiring. Check the mains locations and the connection required by the remote device, rather than assuming it will address a slow broadband service or add Wi-Fi coverage.
For a device intended for use in Great Britain, check the product and supplied power equipment are appropriate for that market, and read the installation and safety instructions. Do this for each unit in a mesh or powerline kit, not just the main router or adapter.
