What to check before buying
Work out where the connection first becomes weak, then choose the route that matches the number of affected rooms, the layout and any practical cable runs.

What to check |
Your needs |
| Find the bottleneck |
Compare wired or near-router performance with remote rooms. Check the router, fibre connection box where applicable, and existing boosters before replacing equipment. |
I want to avoid buying coverage hardware when a broadband-line, router or provider issue is causing the problem. |
| Coverage and placement |
Map weak rooms and likely barriers such as walls, floors, furniture and electrical equipment. Place an extender or intermediate node between the router and the weak area rather than inside the dead zone. |
I need a usable connection in rooms where the signal has to travel through a large or obstructed home. |
| Backhaul and compatibility |
Check exact mesh-family compatibility, firmware requirements and Ethernet-backhaul support on both endpoints. Confirm port availability before planning wired node links. |
I want distant rooms to remain dependable without a weak wireless link between nodes becoming the next bottleneck. |
| Roaming and setup |
Check whether the system creates one network, how it is managed, whether an account is required, and whether it works with the existing modem, ONT or provider router. |
I want to move around the home without repeatedly changing networks, while keeping setup and support manageable. |

NETGEAR Orbi 370 RBE373 WiFi 7 Mesh System, 3-Pack
For widespread coverage needs where a router and two satellites are intended to form one mesh network.
Stated specifications include dual-band BE3600 WiFi 7, 2.5Gbps Ethernet, WPA3, separate IoT and guest networks, VPN support and automatic updates. An existing modem or gateway is required; coverage and wireless speed depend on construction, traffic, devices and installation.

TP-Link Deco BE65 BE9300 Tri-Band Wi-Fi 7 Mesh System, 3-Pack
For a larger home with several persistent dead zones where three mesh units can be positioned along the route to weak rooms.
Stated features include tri-band Wi-Fi 7, 320MHz support, 4K-QAM, a dedicated backhaul band, app management, guest access and parental controls. Confirm the exact Ethernet-port specification and wired-backhaul support if you plan to connect nodes by cable.

TP-Link Deco BE25 Whole-Home Mesh WiFi 7 System, 3-Pack
For several rooms needing a single network with mesh roaming between additional units around the home.
Stated specifications include dual-band Wi-Fi 7, 2.5Gbps Ethernet ports, USB, WPA3, VPN functions and Deco app management. Confirm the connection method for the existing modem, fibre ONT or provider router, and verify wired-backhaul support for this exact variant before planning cable runs.

TP-Link RE220BE BE3600 Wi-Fi 7 Range Extender
For one reachable dead zone where an extender can be placed between the router and the weak room.
Stated features include dual-band Wi-Fi 7, MLO, one 1Gbps LAN port, EasyMesh, WPA3 and Tether or web management. EasyMesh roaming needs a compatible router, and this one-unit extender is not intended as a substitute for planned multi-floor mesh coverage.

Frequently asked questions
How can I tell whether I need better broadband or better Wi-Fi coverage?
Start by checking the broadband line and testing performance at different times. Ofcom advises carrying out several speed tests over several days; if performance is weak close to the router or on a wired connection as well as in remote rooms, coverage hardware may not solve the primary issue. If it is mainly weak in particular rooms while the connection near the router is satisfactory, investigate placement, an extender, mesh or wired backhaul.
When is a mesh system more suitable than one Wi-Fi extender?
Mesh is more suitable for several weak rooms, multi-floor coverage or moving around the home on one network. A single extender is better suited to one reachable dead zone because it repeats the router’s signal and should be positioned about halfway between the router and the weak area. BT says multiple extenders can create overlapping signals and slow the network.
Do walls and floor layout matter more than advertised coverage area?
They can matter substantially. BT says disc range varies with obstructions such as walls and electrical equipment, as well as interference from other Wi-Fi devices. Treat an advertised area as a condition-based manufacturer estimate and plan node placement around the real route between the main router and weak rooms.
What should I check before buying Ethernet-backhaul equipment?
Confirm that both the main router and satellite or node support the same wired-backhaul implementation, that the required Ethernet ports are available, and that a cable route is practical. TP-Link states that both devices must support EasyMesh Ethernet backhaul, and notes that mesh families and firmware support are not automatically interchangeable.
Can a mesh system replace my existing router?
It depends on the mesh model and broadband setup. Ofcom describes mesh as connecting to an existing router, while TP-Link says Deco systems need an external internet source such as a modem or direct Ethernet wall connection and can connect to an existing router. Check the exact model’s supported operating mode and your ISP or ONT requirements before replacing the provider router.
