Choose equipment according to where Wi-Fi is weak and whether Ethernet can reach those rooms. A wired access point or wired-backhaul mesh makes use of an available cable route; wireless mesh can serve several rooms when cabling is impractical, while an extender is a narrower option for one weak area that still receives a usable signal. Check whether the broadband service itself is limiting performance and how new equipment will connect to the existing hub or ONT before buying.
If the connection works near the router but weakens in a bedroom, upstairs room or home office, decide whether a better router position could help or whether that room needs another coverage point. Ofcom identifies the wireless link between a router and devices around the home as a potential bottleneck.
Existing wall ports or a practical cable run may allow a wired access point or wired-backhaul mesh near the weak rooms. Check where the cable starts and ends before choosing equipment; a distant wireless node still needs a workable connection back to the network.
If you plan to add your own Wi-Fi equipment, check which device will handle routing and whether the new system can run in access-point mode. Openreach says the router connects to its Full Fibre ONT; the ONT is not itself a replacement Wi-Fi router.
Compare performance near the router with the rooms that need coverage, then check cable routes and the existing connection before choosing a router, mesh system, access point or extender.
| Priority | What to check | Your needs |
|---|---|---|
| Room-to-room coverage | Compare the connection near the router and in weak rooms. Check whether a more central, unobstructed router position is practical; Ofcom and Openreach identify placement as a coverage consideration. | Wi-Fi works beside the router, but I need a usable connection in another room or on another floor. |
| Wired connections | Locate Ethernet wall ports or a feasible cable route. Check whether the chosen access point or mesh units need an Ethernet switch or Power over Ethernet (PoE) equipment. TP-Link describes Ethernet backhaul as a wired link between Deco units. | There is a cable route to the weak area, and I am willing to plan the installation rather than rely on a wireless link between coverage points. |
| Wireless node placement | For mesh or an extender, check that each wireless coverage point can receive a usable signal from the router or preceding node. Do not plan to place it inside a complete dead zone. | Several rooms need coverage but running cable is impractical; for just one weak area, I can place an extender within reach of the existing Wi-Fi. |
| Provider equipment | Identify the hub and connection type. Confirm router or access-point mode, who handles DHCP, and any model-specific modem-mode instructions before changing the setup. | I want to keep my provider hub or connect a new router to an ONT without losing functions I use. |
| Service versus Wi-Fi | Check performance near the router as well as in distant rooms under similar conditions. Ofcom advises that home Wi-Fi cannot outperform the incoming broadband service. | The connection feels slow everywhere, so I need to establish whether another Wi-Fi device would address the problem at all. |
Ofcom and Openreach identify obstructed locations, including cupboards and under-stairs spaces, as possible coverage problems. Another router left in the same position may still struggle to reach distant rooms.
Where safe and practical, compare coverage from a more central, unobstructed position. If the equipment must stay put, consider coverage points elsewhere in the home.
An extender or wireless mesh node needs a viable upstream connection; it cannot relay a useful connection from a position where it cannot receive one.
Place an extender between the router and the weak room, or position mesh nodes where each has a workable link. Consider Ethernet backhaul if walls or distance prevent that.
Two devices both handling routing can complicate the home network. TP-Link says Deco access-point mode leaves DHCP to the existing router, although some Deco router-mode features are unavailable in that mode.
Decide which device will route traffic, then check the exact mesh model and provider-hub instructions before changing modes.
A wired access point or mesh link needs a usable cable path and suitable connections; a PoE access point also needs compatible power equipment. Openreach distinguishes internal home wiring from its ONT equipment.
Check wall ports, cable routes, switches and power requirements before choosing a wired design. Do not move or remove the Openreach ONT or fibre fittings.
A new cable run, terminations, a switch or PoE equipment may add installation work.
Deco is a mesh-system reference for homes considering Ethernet backhaul or access-point mode behind an existing router.
The UniFi U7 Lite illustrates a wired access-point setup rather than a plug-in wireless extender.
The Orbi 770 series is a reference for a multi-node mesh setup with an optional wired connection between nodes.
The RT-BE86U is a reference for a main-router route where its position and connection suit the home.
The Wi-Fi Extender 2600 is a documented example for one weak area that remains within reach of the main router.
These options cover multi-room mesh systems, an extender for one reachable weak area and a possible replacement main router. The appropriate route still depends on your layout, wiring and existing broadband equipment.

A three-unit mesh option to consider when Wi-Fi is weak in several rooms. The product name specifies dual-band BE3600 and 2.5Gbps Ethernet; check node placement and how the system will connect to your existing gateway.

Consider this three-unit mesh system when several rooms need coverage. Check the exact version’s access-point mode and required features if you intend to keep a provider hub; coverage will depend on where the units can be placed.

This three-pack offers multiple coverage points for rooms away from the main router. Check the exact model and firmware for the operating mode and features you need with your provider equipment, and plan a viable connection between units.

Consider an extender for one weak area if it can be positioned where the router’s signal is still usable. Check pairing with your exact router before relying on an EasyMesh setup; placing the extender inside a complete dead zone will not address the weak upstream link.

A replacement-router option if one suitable router position can serve the rooms you use. Confirm its connection requirements with your provider or ONT before replacing a hub; the BE9300 designation does not establish coverage through your home’s walls and floors.
Compare the connection near the router with the weak room under similar conditions. If it works well nearby but poorly farther away, in-home coverage is a likely issue; if it is poor near the router too, investigate the service and existing equipment before buying mesh or an extender. Ofcom notes that the wireless link can be a bottleneck, but Wi-Fi cannot outperform the broadband service.
You can keep the provider router if the chosen mesh system supports a suitable access-point setup. TP-Link says Deco access-point mode extends the existing network while the root router retains DHCP responsibility; check the exact model because some router-mode features are unavailable in that mode.
Leave the ONT, its power supply and fibre fittings in place. Openreach says the router connects to the ONT by Ethernet; before changing routers, confirm that the new model has a suitable WAN connection and supports your provider’s setup requirements.
Consider wired backhaul when a practical Ethernet route reaches the coverage points, particularly if distance or walls make a wireless link difficult. TP-Link describes Ethernet backhaul as a wired connection between Deco units; wireless mesh remains an option when running cable is impractical, provided each node can maintain a usable upstream signal.
Check the exact hub model and connection type before changing its operating mode. Virgin Media documents modem mode for compatible hubs, but model-specific availability and functions vary; alternatively, an access-point setup may let the provider hub continue handling routing.
