If broadband works well near the router but Wi-Fi fails elsewhere, try a better router position before buying equipment. For one weak area, consider a targeted extender; for gaps across several rooms, consider mesh. Where walls or distance make wireless links unreliable and Ethernet can reach the weak area, a wired access point or wired-backhaul mesh is worth assessing. Replace the router chiefly when the router itself is causing problems, after checking compatibility with your broadband setup.
If Wi-Fi works near the router but falters in a bedroom or garden office, check router placement and whether an extender can receive a usable signal between the router and that area. Which? describes extenders as a targeted way to increase a router’s reach.
Mesh is relevant when people use connected devices in different parts of the home and want coverage while moving between rooms. If thick walls or floors weaken the links between mesh units, check whether the system and your home can accommodate Ethernet backhaul.
For a desk, games setup or streaming area that Ethernet can reach, consider a wired access point or compatible wired-backhaul mesh node. TP-Link’s guidance describes Ethernet backhaul as a physical link between compatible Deco units; the installation still depends on the equipment and cable route.
Work out whether the weak connection follows the room, the router or the broadband service; then match the coverage method to the layout.
| Priority | What to check | Your needs |
|---|---|---|
| Find the cause | Compare the connection near the router with the weak room; try a wired connection where feasible. Check service status and whether other devices are using the connection heavily, as Ofcom advises. | I want to know whether the problem is Wi-Fi coverage before buying equipment for it. |
| Router position | Check whether the router can sit more centrally and higher up, away from obstructions and potential interference. Ofcom notes that Wi-Fi signals weaken as they pass through objects. | One room has poor reception, and moving the existing router is practical. |
| One weak area | For an extender, find an intermediate position where it can still receive the router’s signal. If Ethernet reaches the weak area, check access-point compatibility instead. Which? describes an extender as a targeted option. | I need a connection in a particular room, rather than wider coverage throughout the home. |
| Several rooms | Check the number and placement of mesh units, the route between them and whether the system can work alongside your existing router. TP-Link describes access-point mode for compatible Deco systems used with an existing router. | We use devices across the home and want coverage as we move between rooms. |
| Wired links | Check cable routes, Ethernet ports and support for a wired access point or wired backhaul on the exact models. TP-Link says Ethernet backhaul can provide a more reliable link between compatible Deco units than wireless backhaul. | Walls, floors or distance separate the weak area, and I can run Ethernet to it. |
| Router replacement | Check whether disconnections or trouble with several devices occur near the router too. Before choosing a third-party router, confirm its connection type, required settings and provider support. | The current router may be the problem, not just its position or the reach of its Wi-Fi. |
An extender or mesh system cannot fix a broadband outage or a connection that is already poor close to the router.
Check the connection near the router, the provider’s service status and heavy household usage before deciding that coverage equipment is needed.
A wireless extender or mesh node still needs a usable connection upstream. Ofcom explains that objects and building materials weaken Wi-Fi signals.
Position it where it can receive a sound signal from the router or preceding node. If that position cannot serve the weak area, assess an Ethernet connection.
A third-party router may need connection-specific configuration, and your broadband provider may not support troubleshooting it.
Confirm the broadband connection, modem or ONT arrangement, required settings and whether the supplied router must stay in use.
Walls, floors, node placement and the broadband connection can change the result in your home.
Plan around the actual weak areas and possible node or cable positions rather than a coverage figure alone.
These brand examples illustrate equipment and setup questions; they are not a list of products available in this section.
Deco mesh systems are relevant when adding Wi-Fi around an existing router or connecting compatible units by Ethernet.
Its extender and Orbi mesh ranges represent different approaches to a targeted weak area and broader multi-room coverage.
The eero range includes app-managed, multi-unit mesh kits, including the eero 6 three-pack listed by Amazon in the UK.
These are mesh systems to consider if weak Wi-Fi affects several rooms. If moving the router, a targeted extender or a wired access point fits your layout better, a mesh kit need not be the next purchase.

A three-unit mesh option for coverage across several rooms. If you plan to keep your existing router or connect units by Ethernet, confirm the operating mode, compatibility and backhaul setup for this exact kit.

A three-unit, dual-band BE3600 mesh system for a multi-room layout, with 2.5Gbps Ethernet stated in its product name. Check the exact operating mode and wired-backhaul support if either is essential to your setup.
No image available
A three-unit mesh option for Wi-Fi gaps across several rooms. Its name specifies tri-band Wi-Fi 7; check the exact Ethernet ports and wired-backhaul options before planning a cabled installation.
No image available
A mesh kit to assess for coverage in several rooms. Confirm the individual units in the bundle, the operating mode needed with your router and the backhaul arrangement before ordering.
No image available
A two-unit mesh bundle to consider when the weak areas can be served by two positions. Check its exact ports, operating modes and compatibility with your existing router before deciding where each unit would go.
If the connection is poor close to the router as well as in distant rooms, investigate the service and household usage before buying coverage equipment. Ofcom advises checking for provider faults and whether data-heavy activity is using the connection; compare a wired connection too, where feasible.
Yes, if the mesh system supports a suitable setup with your router. TP-Link’s UK guidance describes access-point mode for compatible Deco systems used alongside an existing router, with a main Deco unit connected to that router by Ethernet. Check the exact model and software version for available modes and features.
Consider it when Ethernet is available or can be run safely and walls, floors or distance make a wireless link between nodes difficult. TP-Link says Ethernet backhaul provides a physical link between compatible Deco units; the result in your home depends on the equipment and installation.
It can be a targeted option if it can receive a usable signal from the existing router at a practical intermediate position. Which? describes extenders as a way to increase reach to a particular area. If that wireless path is heavily obstructed and Ethernet can reach the room, assess a wired access point instead.
