Check whether the broadband service or the home Wi-Fi is causing the problem before buying equipment: Ofcom notes that Wi-Fi cannot outperform the broadband service. If the line is working but coverage is weak across several rooms, consider mesh; for one weak area, consider an extender. A compatible replacement router may address a limiting hub, while direct Ethernet is worth assessing for a fixed computer and powerline is an option where a cable run is impractical and the electrical-circuit requirement is met.
If Wi-Fi works near the router but falters elsewhere, check router placement and where a mesh node or targeted extender could receive a usable signal. Ofcom identifies the wireless connection within the home as a possible bottleneck.
A computer that stays in one place is a candidate for a direct Ethernet connection. Ofcom advises connecting a computer to the router by Ethernet when a faster, more reliable connection than Wi-Fi is needed.
Identify the broadband connection and required settings before choosing a router. TP-Link’s UK compatibility guidance distinguishes DSL, cable/HFC and FTTP setups; a replacement that suits one arrangement cannot be assumed to suit another.
Start with the service and the affected devices, then choose equipment for the location of the problem rather than its advertised maximum speed.
| Priority | What to check | Your needs |
|---|---|---|
| Service or Wi-Fi? | Check the provider’s service status and compare an Ethernet-connected computer with Wi-Fi in the affected rooms. Note whether heavy downloads coincide with the problem. Ofcom says Wi-Fi cannot outperform the broadband service. | I want to know whether new equipment would address the problem before changing my home network. |
| Multi-room coverage | Check which rooms have weak signal, where the router sits and where mesh nodes could be placed. For one targeted weak area, compare an extender instead; Which? distinguishes that use from wider mesh coverage. | Calls or streaming falter in several rooms, or perhaps just one room away from the router. |
| Fixed devices | Check whether a direct Ethernet cable can reach the computer or other fixed device. If not, assess the intended powerline sockets: TP-Link says both adapters must be on the same electrical circuit. | My desk or another fixed device needs a dependable connection without relying on Wi-Fi in that spot. |
| Shared use | Identify which activities run at the same time, check the broadband service first, and look for independent tests of the exact router or mesh kit under multiple-device load. Ofcom identifies the home wireless link as a possible bottleneck. | Several people may be on calls, studying, streaming or gaming at once, so a headline Wi-Fi specification alone will not settle my choice. |
| Router compatibility | Identify whether the service uses DSL, cable/HFC or FTTP, and check the required modem or WAN connection, provider settings and operating mode. Confirm what support the provider offers for third-party equipment. | I am considering replacing the provider hub but need the new setup to connect to my existing service. |
If a provider fault or the service itself is limiting the connection, better in-home Wi-Fi will not restore that missing capacity. Ofcom advises checking for service problems and competing data-heavy activity.
Check the provider’s status information and, where possible, compare Wi-Fi with a computer connected directly to the router by Ethernet. Report a persistent service fault before buying coverage equipment.
Walls, node placement and the wireless link within the home affect results. Which? assesses coverage and multi-device performance rather than relying on headline specifications alone.
Look for independent tests of the exact model and consider where each unit would go in your home.
DSL, cable/HFC and FTTP setups can need different hardware or operating modes. TP-Link’s compatibility guidance distinguishes these connections, and provider support for third-party equipment can be limited.
Confirm the service type, modem or hub arrangement, WAN connection and required settings with your provider. Keep the original hub available for fault diagnosis.
Powerline uses household electrical wiring. TP-Link says adapters on different electrical circuits will not communicate, so a kit may not work between the sockets you intend to use.
Test the pair in the intended wall sockets. If a direct cable run is practical for an important fixed device, assess that route first.
These brand examples point to equipment types and setup checks, not a judgement about every model a brand makes.
TP-Link offers Deco mesh systems, routers and powerline adapters relevant to different home-network layouts.
NETGEAR’s Orbi range includes mesh equipment for homes considering more than one Wi-Fi unit.
eero offers app-managed mesh equipment for whole-home Wi-Fi setups.
These options cover multi-room mesh kits, an extender for a targeted weak area and a powerline kit for a fixed device. Choose a route after checking the broadband service, room layout and installation requirements.

A three-pack to consider when Wi-Fi coverage is weak across several rooms. The product name specifies dual-band BE3600 and 2.5Gbps Ethernet. Check how it connects to your broadband equipment and look for model-specific tests before judging coverage in your home.
No image available
This three-pack is an option for coverage problems across multiple rooms or floors. Check where its units could be placed, how the kit connects to your broadband equipment and independent results for the exact model under shared use.

Consider this three-pack where weak Wi-Fi extends beyond a single room. Confirm the Ethernet port arrangement if you plan to connect fixed devices or cable the units, and check the broadband setup and model-specific coverage results.

An extender is worth considering when one area needs better Wi-Fi rather than the whole home. It needs an existing router and a suitable position within that router’s signal range; check compatibility and the intended wall-outlet location.

This powerline kit is an option for connecting a remote fixed device when running an Ethernet cable is impractical; it is not a Wi-Fi extender. TP-Link says the adapters must be on the same electrical circuit. Test them in the intended sockets before relying on the connection.
Compare a computer connected directly to the router by Ethernet with Wi-Fi in the affected rooms, and check the provider’s service status. If the wired connection is also poor, investigate the service before buying Wi-Fi hardware; Ofcom notes that Wi-Fi cannot outperform the broadband service.
Consider mesh when weak coverage spans several rooms or floors, and an extender when the problem is confined to one area. Which? describes extenders as a targeted option; for either route, check placement and independent testing of the exact model rather than assuming a coverage figure will apply to your home.
Possibly, but confirm your connection type and the replacement’s required hardware and settings first. TP-Link’s UK guidance distinguishes DSL, cable/HFC and FTTP setups, while BT Business says a third-party router must be compatible with its service. Keep the provider hub available for troubleshooting.
Yes, if you can conveniently cable a fixed computer to the router. Ofcom says that direct Ethernet should give a computer a faster, more reliable connection than Wi-Fi. If you also plan to cable mesh units, check that the exact kit supports your intended wired arrangement.
No. TP-Link says both adapters must be on the same electrical circuit for its powerline network to work. Check the intended sockets and test the pair there before depending on it for an important fixed device.
