Start by testing a computer connected to the router by Ethernet and comparing the result with the speed in your broadband contract or confirmed by your provider, as Ofcom advises. If that connection is adequate but particular rooms have weak Wi-Fi, try router placement before choosing an extender for one reachable dead spot, mesh for several rooms or floors, or Ethernet for a fixed device. If the wired connection is also inadequate, speak to your provider before buying equipment to extend Wi-Fi coverage.
If Wi-Fi works near the router but weakens in a particular room, check router placement and test the broadband connection by Ethernet. An extender is worth considering if it can receive a usable signal between the router and the weak area.
If weak signal affects several rooms or floors, a mesh system offers a way to place connected units around the home. Check where its main unit must connect and where the other units can receive a useful connection.
If a computer or console stays in one place and a cable route is practical, consider connecting that device directly to the router. Ofcom recommends Ethernet when checking broadband speed because Wi-Fi can slow the connection being measured.
Establish whether the broadband connection or the in-home Wi-Fi is limiting you, then match the equipment to where the weak signal occurs.
| Priority | What to check | Your needs |
|---|---|---|
| Broadband or Wi-Fi? | Following Ofcom’s guidance, test a computer or tablet connected directly to the router by Ethernet. Compare the result with your contracted or provider-confirmed speed; a Wi-Fi test alone can read lower. | Is the connection poor even beside the router, or only over Wi-Fi in certain rooms? I want to establish that before buying coverage equipment. |
| One weak area | Check router placement and whether an extender can receive a usable signal between the router and the dead spot. NETGEAR describes conventional extenders as receiving and rebroadcasting the router’s signal. | My connection works elsewhere, but one room needs coverage. I can position an extender where the router signal still reaches it. |
| Several weak areas | Check the number of mesh units, possible locations and the connection required by the main unit. Ofcom describes mesh units placed around the home as a way to extend Wi-Fi coverage. | Weak signal affects several rooms or floors, and I need to move between those areas with connected devices. |
| Existing equipment | Identify your ISP router, modem or fibre ONT and check the exact system’s connection and operating modes. TP-Link says the main Deco needs Ethernet; eero says bridge mode leaves management with the existing router but affects some eero Plus features. | I want to retain my existing broadband equipment without assuming a new mesh system will connect to it wirelessly. |
| Fixed devices | Check for an Ethernet connection at the device and a practical cable route to the router. Test the wired connection before deciding whether that device needs different Wi-Fi equipment. | My work computer or console stays put, so a cable may suit it even if other devices still need wireless coverage. |
| Router or service | Ask your provider about a newer router if the existing router appears to be the Wi-Fi bottleneck. If the wired result is inadequate too, check the connection with your provider before considering a broadband-service change. | I would rather address the limiting connection than add an extender to a network that is already slow at the router. |
Wi-Fi can reduce a speed-test result, so a wireless-only test may point you towards coverage equipment when the broadband connection also needs attention.
Use Ethernet to test at the router and compare the result with your contracted or provider-confirmed speed, as Ofcom advises.
An extender rebroadcasts the signal it receives from the router. A weak connection at the extender’s location limits what it can pass on.
Place it between the router and the weak area where it can still receive a usable signal; consider mesh or a wired connection if the weak areas are farther apart.
TP-Link says the main Deco unit needs a physical Ethernet connection. Router and access-point modes also change how Deco connects to an existing router; eero says bridge mode affects some eero Plus features.
Identify the existing router, modem or fibre ONT, then check the exact mesh model’s connection, operating mode and feature conditions before buying.
TP-Link says Deco, OneMesh, EasyMesh and Omada use different technologies; an Archer router and Deco system do not provide seamless roaming together.
Check compatibility between the exact router, extender and mesh-node models rather than relying on the brand name.
Deco mesh systems, Archer routers and extender ranges offer different ways to address weak home Wi-Fi.
NETGEAR offers range extenders for local weak areas and Orbi mesh systems for coverage using multiple units.
eero is another mesh option to consider when retaining an existing router is part of the setup.
These systems are mesh options for homes considering coverage across several rooms. Decide whether mesh addresses your connection problem before comparing their pack sizes and checking the setup against your existing equipment.

A three-unit mesh option to consider when weak Wi-Fi affects several rooms. TP-Link says the main Deco unit needs an Ethernet connection; check the operating mode against your existing broadband equipment. BE3600 is a product designation, not a measured speed in your home.

Consider this three-unit mesh system for coverage across multiple rooms. Confirm where the units can be placed and which network mode works with your ISP equipment; TP-Link requires an Ethernet connection for the main Deco unit.

A three-unit mesh option for a home with several weak areas; its title identifies a tri-band Wi-Fi 7 variant. Check the exact model’s ports and intended network mode for your setup. TP-Link says the main Deco unit must connect by Ethernet.

This dual-band BE3600 mesh system is a three-pack to consider for several rooms; its product name specifies 2.5Gbps Ethernet. Check how it connects to your ISP equipment and whether its unit placement fits your home. BE3600 does not establish the speed you will receive.

A two-unit mesh bundle to consider when coverage needs to extend beyond the router’s location. Check its ports, connection to existing ISP equipment and suitable placement before deciding whether two units fit your home.
Connect a computer or tablet directly to the router by Ethernet and compare its speed with your contracted or provider-confirmed speed, as Ofcom advises. If the wired connection is adequate but distant rooms remain weak, focus on in-home Wi-Fi; if it is inadequate too, investigate the service and provider equipment before buying coverage hardware.
It may, but check the exact system’s physical connection and operating modes. TP-Link says the main Deco needs Ethernet and documents router and access-point modes for an existing router; eero says bridge mode leaves network management with the existing router but affects some eero Plus features.
Place it where it can still receive a usable signal from the router, between the router and the weak room. An extender rebroadcasts the signal it receives, so putting it inside a complete dead spot will not give it a useful connection to pass on.
Do not assume they will form one mesh. TP-Link says Deco, OneMesh, EasyMesh and Omada use different technologies, and an Archer router with Deco does not provide seamless roaming. Check compatibility for the exact models you plan to combine.
