Consider replacing the router if one well-placed Wi-Fi point can reach the rooms you use and the existing router or its position is the likely limitation. Consider mesh Wi-Fi when distance, floors or building materials leave rooms beyond that point: additional nodes can bring Wi-Fi nearer, provided they have a usable connection back to the main unit. Before buying either, compare Wi-Fi with a wired connection at the router and check how the new equipment will connect to your broadband service.
If the connection works near the router but falters in another room, the choice is whether a single Wi-Fi point can reach that room or you need another point nearer to it. Ofcom identifies the wireless link inside the home as a possible performance bottleneck.
Calls, streaming and gaming can make a poor connection more noticeable. Check whether the difficulty is confined to particular rooms or also occurs over a wired connection at the router before choosing coverage equipment.
If the provider’s router must stay in place, check which device will manage the network. TP-Link’s UK Deco guidance describes access-point mode for keeping the existing router in that role; its cited setup requires the main Deco to connect by Ethernet.
Consider it when: One suitably placed router is likely to reach the rooms where you need Wi-Fi.
Trade-off: Replacing one router does not put a new Wi-Fi point in a distant room; check setup and support with your broadband provider if using your own equipment.
Consider it when: Separate rooms or floors need additional Wi-Fi points and there are suitable places to position the nodes.
Trade-off: The main unit needs a suitable connection to the broadband equipment, and the chosen operating mode can affect network-management features.
| Priority | What to check | Your needs |
|---|---|---|
| Find the weak link | Compare a device’s Wi-Fi connection in the affected room with a wired Ethernet connection at the router, where practical. Ofcom notes that the wireless link can be a bottleneck; a poor wired result calls for investigation beyond Wi-Fi coverage. | I want to know whether equipment inside the home is the problem before changing it. |
| Room-to-room coverage | Identify the rooms that need service and possible positions for a router or mesh nodes. Check that a wireless node can receive a usable connection from the main unit rather than placing it only at the far end of a dead spot. | The connection works near the router, but I need Wi-Fi in rooms farther away. |
| Wired connections | Check the broadband hand-off and the chosen equipment’s WAN and LAN ports. If you plan to cable a remote mesh node, confirm that the exact model supports your intended Ethernet-backhaul arrangement. | I can run a cable to a distant room, or I need a wired connection for a device there. |
| Network controls | Decide whether the existing router or new equipment will manage the network. Check the exact model and mode for required parental controls, guest-network isolation, VPN, IPv6 and forwarding features; TP-Link says gateway-dependent Deco features are unavailable in its cited access-point mode. | I need to keep particular network controls while retaining my current broadband router. |
Extra Wi-Fi points address the in-home wireless connection, not the speed delivered to the router. Ofcom also identifies factors such as congestion and device limitations that can affect what a device experiences.
Compare an Ethernet connection at the router with Wi-Fi in the weak room. If the wired connection is also poor, investigate that result with your broadband provider rather than relying on mesh as the fix.
A remote node still needs a usable connection back to the rest of the network. Its position matters as well as the room it is intended to serve.
Try a position between the main unit and the weak room, then check the connection there. If cable routing is practical, confirm the model’s Ethernet-backhaul options.
For the Deco configuration described in TP-Link’s UK guidance, access-point mode leaves network management with the existing router and makes gateway-dependent Deco features unavailable. Available functions can differ by model and software version.
List the controls you use, including any requirement for an isolated guest network, and confirm which device provides each one in the planned setup.
A coverage figure alone cannot establish where nodes can be placed or how they will connect through your home’s layout.
Plan positions around the actual weak rooms, check the available wired connections and assess the connection after installation.
Deco mesh systems are relevant when adding Wi-Fi points while either keeping an existing router or choosing a mesh-led setup.
Orbi includes multi-node mesh systems, with features that vary by model.
Standalone routers with an AiMesh expansion route may suit a home starting with one router and considering additional compatible nodes later.
These three-pack mesh systems are options for adding Wi-Fi points across rooms. They do not replace the initial check of your broadband connection, and their installation details need to fit your existing equipment.

A three-unit mesh option for placing Wi-Fi points in different parts of the home. The product name specifies dual-band BE3600 and 2.5Gbps Ethernet. Check its connection to your broadband equipment and the operating modes needed for your setup; coverage in individual rooms depends on placement and layout.

A three-unit option to consider when one router position does not reach the rooms you use. Check the BE22’s exact Ethernet-backhaul arrangement, broadband connection and available network controls in the mode you plan to use.

Three mesh units provide positions to consider across separated rooms. Before choosing it for a wired remote node or an existing-router setup, confirm the BE25’s backhaul options, operating mode and broadband compatibility.
No image available
A three-unit mesh option for considering Wi-Fi points beyond the main router. Its name identifies a tri-band BE9300 system; confirm the exact Ethernet ports, backhaul configuration and operating modes against your intended installation.
Compare the connection in the weak room with one near the router and, where practical, a wired Ethernet connection at the router. Ofcom identifies the wireless link as a possible bottleneck. If the wired connection is also poor, investigate the broadband connection or other causes before buying equipment solely for coverage.
It can in a compatible setup, but check the exact system and operating mode. TP-Link’s UK Deco guidance describes access-point mode for retaining the existing router as network manager and requires the main Deco to connect physically by Ethernet in its cited configuration.
Not necessarily: the connection between nodes depends on the system and how you install it. If you plan to use a cable to reach a distant room, confirm Ethernet-backhaul support and the permitted connection layout for the exact model. With a wireless connection, position each node where it can still receive a usable signal.
Do not assume it will. TP-Link says gateway-dependent functions are unavailable in the Deco access-point mode covered by its guidance. Check the chosen model and software version, then establish whether required controls and guest-network isolation will come from the existing router or the mesh system.
