If the full-fibre connection works well near the router but Wi-Fi fades upstairs, choose equipment for the size of the coverage gap and the wired connections you need. Consider an extender for one limited weak spot, mesh for several rooms, or Ethernet-backed mesh and wired access points where cabling is practical. Replace the supplied router only after checking your provider's connection settings and any phone service that depends on its hub.
Your connection works near the router, but Wi-Fi is unreliable across floors or beyond walls and other obstacles. Ofcom advises that a poor Wi-Fi result does not necessarily indicate a fault with the broadband line.
You have Ethernet cabling, or could install it, and want to connect devices in an office or other distant room without depending entirely on a wireless link between Wi-Fi points. TP-Link and ASUS both document wired connections between compatible mesh units.
You need wider Wi-Fi coverage but may have to retain the supplied router for your broadband setup or provider-managed phone service. Check which device will handle routing before connecting a new mesh system or access point.
Check whether the problem is limited to Wi-Fi inside the home, then decide how many rooms need coverage, where Ethernet can reach and whether the supplied hub must stay in place.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage across rooms and floors | Map the weak rooms and possible positions for an extender, mesh units or access points; check whether Ethernet reaches them. | If Wi-Fi works downstairs but drops out upstairs, I need the signal to reach those rooms without relying on a poorly placed extra unit. Around 36% of consumers put coverage first. |
| Wired connections | Check usable Ethernet ports, cable routes and wired-backhaul support; plan any switch or power-over-Ethernet equipment needed for access points. | When work or entertainment devices need a wired connection away from the router, I want the network layout to accommodate them. Roughly 29% of consumers prioritise wired connections. |
| Provider and phone compatibility | Confirm the required WAN connection and provider settings, plus any phone service tied to the supplied hub. | Before replacing my provider's router, I need to know that broadband and any hub-dependent phone service will continue working. About 21% of consumers make compatibility their primary concern. |
| Security support and setup | Check the published security-update period and whether the operating mode you plan to use changes the features available. | If I want a system I can maintain without complex network changes, clear updates and manageable settings matter most. Around 14% of consumers put support and setup first. |
Ofcom notes that a slow Wi-Fi result does not always mean the broadband line is faulty. Distance, obstacles and conditions inside the home can affect the wireless result.
Compare results near the router and in the weak room. If the connection is unreliable throughout the home, check the provider's service status before buying Wi-Fi equipment.
Openreach describes an optical network terminal, or ONT, connected by Ethernet cable to a router's WAN port. That physical connection alone does not establish which provider settings a replacement router needs or whether a provider-managed phone service will keep working.
Ask your provider for the connection requirements for your service and check whether anyone in the household relies on the supplied hub for phone service.
An unsuitable setup can mean time spent restoring the connection or keeping the original hub in use.
An extender relies on the Wi-Fi it receives. Ofcom describes extenders as amplifying an existing signal, so placement matters when addressing a dead zone.
For one weak area, position the extender where it can still receive the router's signal. If Ethernet reaches the room, consider a wired access point; for several rooms, assess mesh placement and possible wired connections between units.
Network equipment needs a maintainable security setup. A wired access point may also require compatible power-over-Ethernet equipment; Ubiquiti says the available PoE power must exceed the connected devices' total requirements.
Check the manufacturer's published security-update period. For a PoE installation, confirm each access point's power requirement and the power available from the intended switch or injector.
A wired installation may also require an injector, a suitable switch or additional cabling.
Its Deco range is relevant when considering mesh coverage alongside an existing router or with wired connections between units.
AiMesh is relevant to households considering a router that can work with compatible additional nodes.
Its mesh setup is relevant when deciding whether a gateway can connect to the fibre equipment or should operate alongside an existing router.
Its UniFi access points are relevant when Ethernet cabling and centrally managed Wi-Fi suit the home's layout.
These choices cover multi-unit mesh systems for coverage across rooms, an extender for a limited weak spot and a router to consider where one router position and additional wired connections suit the home. Check provider requirements before using any new device to replace the supplied hub.

Consider this three-unit system when Wi-Fi needs to reach several rooms rather than one isolated weak spot.
The listed variant is dual-band BE3600 with 2.5Gbps Ethernet. If you intend to wire the units together, confirm wired-backhaul support and the connections available on each unit before planning cable runs.

This three-unit mesh choice is relevant when coverage is weak in several rooms and you can position units between the router and those rooms.
TP-Link documents wired and wireless arrangements for Deco systems, but follow the setup instructions for this model and your chosen router or access-point mode. Confirm provider settings before replacing the supplied hub.

Consider an extender for one weak area when the existing router still provides a usable signal at the extender's intended position.
Check placement before buying: an extender cannot be positioned solely by where the dead zone begins. If the main need is several additional wired connections, assess the port layout separately.

This three-unit option is relevant when the coverage problem extends across rooms or floors.
If you also need Ethernet connections in distant rooms, check the number and role of this variant's ports and whether its units can use wired backhaul. Confirm the required provider settings before replacing the supplied router.

Consider a replacement router when the home can be served from one router position and the current hub's wired connections do not meet your needs.
Check the connections you need and your provider's authentication and phone-service requirements before swapping hubs. If coverage later requires mesh units, confirm compatible expansion equipment and what is included.
Compare the connection near the router with the result in the weak room before choosing new hardware. Ofcom says a slow Wi-Fi test does not always indicate a broadband-line fault; if service is unreliable throughout the home, check the provider's fault status rather than assuming mesh will fix it.
The ONT connects by Ethernet cable to a router's WAN port, according to Openreach, but that does not by itself establish that a particular replacement will work with your service. Confirm your provider's authentication requirements and any phone service that depends on the supplied hub before changing routers.
Use the mesh system as the router only when its setup meets your provider's requirements and you do not need the original hub to retain a service. Otherwise, check the system's access-point or bridge arrangement; TP-Link documents distinct Deco topologies, while eero says its bridge mode disables some advanced features.
Check the manufacturer's published minimum security-update period and how updates are provided for the product you intend to buy. The UK Office for Product Safety and Standards says the consumer connectable product security regime took effect on 29 April 2024 for products within its scope; applicability and seller information should be checked for the particular product and delivery location.
