Test the connection by Ethernet at the router before buying Wi-Fi equipment: Ofcom advises using a wired connection for a more accurate broadband speed test, because Wi-Fi can slow the result. If the wired result meets expectations but one reachable room has weak Wi-Fi, consider an extender; for weak coverage across several rooms or floors, assess mesh and where its nodes could go. A replacement router needs to suit your broadband setup, while Ethernet or powerline may be more useful for a fixed device where the connection route is practical.
If Wi-Fi works near the router but struggles in a bedroom, upstairs room or another particular spot, focus on whether a usable signal reaches a point between the router and that room. An Ethernet-fed access point is another route if a cable can reach it.
Where the problem recurs across floors or regularly used rooms, consider where several mesh nodes could sit and how they would connect. TP-Link describes its Deco systems as a unified network across multiple units; the layout and node positions still matter.
If slowdowns coincide with several people streaming, studying or downloading, check what else is using the connection before attributing the problem to coverage. Ofcom recommends checking data-heavy activity and using an Ethernet connection when testing broadband speed.
Start by separating broadband speed from in-home Wi-Fi performance, then match the equipment to the number of weak areas and the connections you can install.
| Priority | What to check | Your needs |
|---|---|---|
| Broadband or Wi-Fi? | Run a speed test over Ethernet at the router and compare it with your service information. Ofcom says Wi-Fi can slow a speed-test result; also check for outages and data-heavy activity. | I want to know whether an in-home upgrade addresses the problem before buying equipment. If the wired result is below the expected service level, I should investigate the service with my provider. |
| One weak area | Check whether the router signal is usable partway to the room. TP-Link advises placing an extender between the router and weak area; check for Ethernet access-point mode if a cable can reach the room. | Most rooms work well, but I need a connection in one particular place without relying on an extender installed inside the dead zone. |
| Several weak areas | Map the rooms and floors needing coverage, then plan mesh node positions and their links back to the network. A wireless link still needs a workable path between nodes. | Wi-Fi drops off in several places, and I want to move around the home without managing separate networks for each area. |
| Simultaneous use | Note when slowdowns occur and what other devices are doing. Check broadband performance first, then assess router capacity and device compatibility rather than judging by a Wi-Fi generation alone. | Several people may be online at once, so I need to distinguish a busy broadband connection from poor wireless coverage. |
| Fixed devices | Check whether Ethernet can reach a PC, TV, console or access point. If considering powerline, confirm that the kit and the intended sockets suit the home’s wiring arrangement. | A device stays in one weak-Wi-Fi room, and a wired connection may be more practical than extending wireless coverage throughout the house. |
| Router replacement | Confirm the broadband connection type, modem or ONT arrangement, ISP setup requirements and ports before choosing a retail router. Ofcom notes that setup and provider support can differ from using the supplied router. | Coverage is poor across much of the home, but I do not want to replace provider equipment without knowing whether the new router will work with my service. |
A slow Wi-Fi test cannot show on its own whether the bottleneck is the wireless link or the broadband service. Extra coverage equipment will not repair a slow line.
Follow Ofcom’s advice to test through Ethernet at the router, compare the result with your service information and investigate a poor wired result with the provider.
An extender depends on the router signal it receives, so a location with little usable signal is a poor starting point for the new connection.
Place it between the router and weak area where reception is still usable, as TP-Link advises. If a cable reaches the room and the model supports access-point mode, consider that route instead.
Powerline carries a network connection over electrical wiring, making the wiring and intended socket locations relevant to whether a kit suits the room.
Check the kit’s installation requirements against the sockets you plan to use before choosing it; keep Ethernet or a wireless route in mind if the wiring arrangement is unsuitable.
Ofcom notes that an independently purchased router can be harder to set up and that the broadband provider may not be able to help with problems involving it.
Confirm connection compatibility, ISP configuration, required ports and how the new router would connect to any existing modem or ONT before replacing provider equipment.
These ranges illustrate different equipment routes; a brand name alone does not establish that a particular model suits your home.
Its home-networking range includes Deco mesh systems alongside extenders and powerline equipment.
Its Orbi range focuses on multi-unit home mesh systems.
Nest Wifi Pro is an expandable mesh option for households considering Google’s home-networking setup.
AiMesh is relevant to buyers considering a network built from compatible ASUS routers.
These options cover multi-unit mesh systems for several weak rooms and an extender for a more limited weak area. Compare their stated configurations with your layout and broadband setup; a product specification is not a coverage result for your home.

A three-pack mesh option to assess for weak coverage across several rooms. Its title specifies dual-band BE3600 WiFi 7 and 2.5Gbps Ethernet; check how the units would be positioned and whether the system suits your broadband connection and ISP setup.
No image available
Consider this three-pack where several rooms need a coordinated mesh network rather than a relay for one spot. Check possible node positions, the connection to your modem or router, and the setup required by your broadband service.

This three-pack is another mesh route for weak coverage in multiple rooms. Plan where its units could receive a usable connection, and confirm the broadband connection and ISP setup requirements before replacing or connecting equipment.
No image available
An extender to consider for one weak area when a usable router signal reaches a suitable installation point. Place it between the router and that area, as TP-Link advises, and check the exact router model before relying on EasyMesh integration.

The product title identifies a three-pack mesh system, so assess it as a multi-room Wi-Fi option rather than a powerline kit. Check its node placement and broadband setup against your home before choosing it.
Test a device connected to the router by Ethernet and compare the result with your broadband service information. Ofcom recommends a wired test because Wi-Fi can slow the result. If wired performance is below the expected service level, investigate with your provider; if wired performance is satisfactory but particular rooms struggle, examine router placement and in-home coverage.
Put it between the router and the weak area where it can still receive a usable router signal, rather than in the dead zone. TP-Link recommends this placement and suggests an Ethernet-fed access point where a stable wireless link is not possible and the equipment supports that mode.
Consider mesh when weak coverage affects several rooms or floors and you want a coordinated network across multiple nodes. An extender is a more targeted route for one reachable weak area; either choice still depends on placing its equipment where the links can work.
Do not assume it will: powerline uses the home’s electrical wiring, so check the kit’s installation requirements and the intended sockets before buying. If that route is unsuitable, consider whether Ethernet cabling or a wireless coverage option is practical for the room.
A retail router may be an option if it is compatible with your broadband connection and ISP setup. Check the modem or ONT arrangement and required ports first. Ofcom cautions that an independently purchased router can be harder to set up and that the provider may not be able to help with problems involving it.
