Compare the connection near your main router with the problem room, including when several people are online. If only certain rooms struggle, choose an in-home coverage route: mesh for several weak areas, an extender for one reachable dead zone, or a wired or powerline connection for a fixed device. If performance is poor near the router too, assess the broadband service before replacing Wi-Fi equipment; a new router is worth considering only when the existing router is the limiting part of the home setup.
If Wi-Fi drops across floors or as people move around the home, look at a whole-home coverage route rather than treating each room separately. Ofcom identifies in-home Wi-Fi as distinct from the broadband service; mesh makers also describe systems designed to manage coverage across multiple nodes.
A workstation used for calls, a games console or a TV may benefit from a direct connection more than from wider wireless coverage. Ofcom recommends connecting a computer to the router by Ethernet when connection speed and reliability matter.
If the connection is slow even close to the router when several people are calling, streaming or gaming, check the broadband service as well as the home network. Ofcom distinguishes these simultaneous-use needs from a weak signal in one room.
Test near the main router before choosing equipment: a room-specific drop and a connection that slows throughout the home call for different responses.
Consider it: Several rooms need coverage, especially when people move between them.
Plan for: A wired connection for the main unit and a setup mode that works with your existing router. TP-Link says its main Deco unit cannot wirelessly repeat that router.
Consider it: One room has a weak signal, but an intermediate socket still receives usable Wi-Fi.
Plan for: Placement away from the dead zone; TP-Link suggests starting roughly halfway between the router and the weak room.
Consider it: Walls or floors make a wireless link difficult and running Ethernet to another room is impractical.
Plan for: Checking the intended sockets: TP-Link says its powerline adapters must share the same electrical circuit.
Consider it: A fixed computer, console or TV needs a dependable connection and a cable route is practical.
Plan for: The physical cable run; it does not extend wireless coverage for devices carried between rooms.
Consider it: The existing router itself appears to limit nearby Wi-Fi coverage or struggles with connected devices.
Plan for: Checking the provider equipment and connection arrangement before changing routers.
Consider it: Performance is poor near the router too, particularly during simultaneous household use.
Plan for: Checking service performance and what is available at your address. Ofcom notes that faster broadband cannot by itself remove a room-specific Wi-Fi dead zone.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage across rooms | Check where mesh nodes could go, how the main unit connects by Ethernet and whether access-point mode suits your router setup. | When calls or streams falter as I move around the home, I want usable Wi-Fi in several rooms rather than a fix for one spot. Around 36% of consumers put whole-home coverage first. |
| Fixed-device reliability | Check whether Ethernet can reach the device; if considering powerline, confirm that the intended sockets share an electrical circuit. | For a desk used for calls or a fixed gaming setup, I would prioritise a dependable connection over roaming. Reliable fixed-device access comes first for around 29% of consumers. |
| One weak room | Check for an intermediate socket where an extender still receives a usable signal from the router. | If the problem is confined to one room, I want to address that gap without changing the whole network. Around 21% of consumers chiefly need a single-room fix. |
| Broadband capacity | Compare performance near the router at different times with your service expectations and the options available at your address. | When everyone is online and even the area near the router slows down, I need to assess the incoming connection before adding Wi-Fi equipment. Broadband capacity is the primary concern for around 14% of consumers. |
Ofcom points out that Wi-Fi cannot outperform the broadband connection feeding it. Equipment that improves signal around the house cannot raise the incoming service speed.
Compare performance near the router with the weak room and check for provider faults before choosing a coverage product.
An extender must receive a usable signal before it can repeat it. Walls and interference can weaken that link.
TP-Link suggests starting roughly halfway between the router and the weak area, then adjusting the position using the extender’s signal indicator or app.
TP-Link says its powerline adapters need to share the same electrical circuit, so the intended socket locations matter.
Confirm the circuit arrangement before choosing a kit and check the seller’s applicable return terms in case it does not suit the property.
Two devices both performing routing can complicate the network, while overlapping Wi-Fi networks may make device selection confusing.
Connect the main mesh unit as instructed and choose router, bridge or access-point mode only where your equipment supports it. Follow the mesh maker’s and broadband provider’s setup guidance.
Offers Deco mesh systems, Wi-Fi extenders and powerline adapters, giving households different routes for different room layouts.
Its Whole Home Wi-Fi range is relevant to households considering a mesh system alongside an existing router.
An app-managed mesh range for households considering coverage across several rooms.
Its Orbi range includes mesh configurations for households considering newer wireless and wired-network features.
These choices include four mesh systems for households assessing coverage across several rooms and a powerline kit for extending a connection to another room. Check the connection route and your existing router setup before choosing between them.

Consider this mesh set if coverage is weak in several rooms and you can position three units around the home.

Consider this three-unit mesh set where several rooms need coverage and you can accommodate a router-and-satellite arrangement.

Consider this three-unit mesh set when the main problem is Wi-Fi coverage across several rooms rather than a slow incoming service.

Consider this mesh set if you need to place units across several weak areas and are assessing a tri-band system.

Consider this powerline route when another room needs a network connection but a long Ethernet cable is impractical.
Start by comparing performance close to the main router with the weak room and with busy periods. Ofcom says Wi-Fi cannot outperform the broadband service: a problem mainly in one room points towards coverage or interference, while slow performance near the router calls for a service check before buying coverage equipment.
It can, provided the system supports an appropriate setup with your router. TP-Link says Deco offers Router and Access Point modes with an existing router, but its main unit must have a physical Ethernet connection; check which device will handle routing and which mesh functions remain available in the chosen mode.
Virgin Media describes modem mode as a way to connect your own Wi-Fi equipment to a compatible Hub. Check the instructions for your particular Hub and mesh model before choosing a setup; do not assume every Hub offers the same modes or retains the same functions after a mode change.
Consider powerline when walls or floors make a wireless link difficult and an Ethernet run is impractical. TP-Link says its adapters must share an electrical circuit, so confirm the intended sockets before purchase; the wiring in the property also affects whether the route suits your needs.
Follow the setup instructions for your mesh system and broadband router rather than switching it off automatically. TP-Link recommends disabling the existing router’s Wi-Fi alongside Deco to reduce interference, but first make sure the mesh is working and check whether any services you use depend on the original Wi-Fi network.
