Check whether the problem is the incoming broadband service or Wi-Fi coverage before buying equipment: as Ofcom explains, Wi-Fi cannot outperform the broadband connection. For one weak room, consider an extender where the router signal still reaches its placement point; for several weak rooms, compare mesh systems. Replace the router only after checking that it is the limiting device and that a replacement will work with your service; consider powerline for a fixed wired device if the home’s electrical circuits are suitable.
If Wi-Fi works elsewhere but struggles in a home office, bedroom or media room, an extender may address the targeted area. Powerline is another option when the difficult room needs a connection to a fixed wired device and the electrical setup is suitable.
When calls, study, streaming or gaming take place in different rooms or on different floors, compare mesh systems and plan where their units could go. Which? distinguishes this wider-coverage task from extending Wi-Fi into one targeted area.
If the current router disconnects frequently or may be limiting the network, check the incoming service and your provider’s connection requirements before replacing it. A new router is not, by itself, a fix for a provider outage or every distant-room dead spot.
Rule out a connection-wide problem first. Then decide whether the priority is one weak room, coverage across several rooms or a wired connection to a fixed device; consider router replacement separately if the router itself appears to be the constraint.
| Concern | What to check | Who this matters to |
|---|---|---|
| Connection or coverage? | Check the provider’s outage information and whether wired devices or rooms near the router are affected. Ofcom notes that Wi-Fi cannot outperform the broadband service. | If the whole household connection has slowed or stopped, I need to establish the cause before choosing hardware. Around 29% of consumers put that diagnosis first. |
| Several weak rooms | For mesh, consider unit placement and whether wired backhaul is practical; do not treat a coverage claim as a guarantee for your floorplan. | Calls, study and entertainment happen in different parts of my home, so one targeted extension may not meet the need. Roughly 36% of consumers prioritise multi-room coverage. |
| One weak room | Check that an extender can receive a usable router signal at its planned position. If roaming matters, confirm compatibility with the existing equipment. | Wi-Fi works elsewhere, and I want to reach one distant room without changing the whole network. Around 21% of consumers make that targeted coverage their priority. |
| Fixed wired device | For powerline, check the intended socket circuits and compatibility with any existing adapters; advertised rates are not guaranteed throughput. | A TV, desktop or console needs a connection where the wireless route is awkward. Roughly 14% of consumers put difficult-room wired connectivity first. |
An extender or mesh system cannot repair a provider outage or make the incoming broadband service faster, as Ofcom’s guidance makes clear.
Check the provider’s service information and whether the problem occurs near the router or on wired devices before choosing Wi-Fi equipment.
Walls, floors and unit placement affect the signal between mesh nodes; the quoted coverage does not establish how a system will perform in your home.
Plan possible node positions and consider a wired connection between nodes where practical.
Router setup depends on the service and supplied hub. BT Business sets compatibility conditions for using your own router, while Virgin Media’s modem-mode options differ by Hub model.
Confirm the connection type, hub model, required settings and support arrangements with your provider before ordering.
Allow for setup time; provider troubleshooting may also be more limited when you use your own equipment.
TP-Link’s guidance says actual powerline throughput and range depend on conditions in the property. G.hn equipment is not interchangeable with HomePlug AV/AV2 adapters.
Check the intended socket circuits and adapter standard, particularly if you are expanding an existing kit.
TP-Link’s UK range spans targeted extenders, Deco mesh systems, standalone routers and powerline kits.
NETGEAR positions its Orbi 770 mesh range for busy connected homes and multi-gig broadband plans.
ASUS is relevant when considering a standalone router with wired-device connections or possible later network expansion.
These products cover multi-room mesh, a targeted Wi-Fi extender and a powerline kit for a fixed wired device. Match the route to where the connection fails before comparing individual models.

Consider this three-unit mesh system when Wi-Fi is weak across several rooms. TP-Link lists wired and wireless backhaul for the Deco BE22; plan unit placement around your floorplan and check how a unit will connect to your existing broadband equipment.

Consider this three-pack for coverage across multiple rooms. Its product name specifies dual-band WiFi 7 and 2.5Gbps Ethernet; check where the units could be placed and how the system would connect to your existing modem or gateway.

This three-pack is an option when several rooms need mesh coverage. Check the floorplan and proposed unit positions rather than relying on a coverage claim; confirm the port arrangement and installation requirements if your setup depends on them.

Consider this extender for one weak room if it can be placed where the existing router’s signal is still usable. TP-Link lists EasyMesh compatibility for the RE220BE, but the corresponding roaming benefit requires compatible network equipment.

Consider this powerline kit for a fixed wired device in a room where Wi-Fi is difficult. Check that the intended sockets can support the connection; TP-Link cautions that actual powerline throughput and range vary with electrical conditions, so AV1300 is not a guaranteed connection speed.
Check whether the problem affects the whole connection or mainly rooms far from the router, and look for a provider outage. Ofcom explains that Wi-Fi cannot outperform the incoming broadband service; an extender or mesh system will not resolve a service fault or an insufficient connection.
Choose an extender to target one area where it can still receive a usable router signal; compare mesh systems when several rooms need coverage. Which? distinguishes targeted extension from wider whole-home coverage, while placement and the building layout remain important for either choice.
A third-party router is an option only when it is compatible with your particular service and setup. BT Business says its customers can use a compatible router but must account for connection requirements and support arrangements; Virgin Media says modem mode is available on Hub 3, 4 and 5, but not currently on Hub 5x. Check your own provider and hub model before buying.
Consider powerline when a fixed device needs a wired connection in a room that is difficult to reach by Wi-Fi, provided the intended electrical setup is suitable. TP-Link cautions that throughput and range vary with electrical conditions; also check adapter compatibility if you already use powerline equipment.
