Check the broadband service and router position before buying equipment: as Ofcom explains, in-home Wi-Fi cannot outperform the incoming connection. For weak signal across several rooms, compare mesh systems; for one weak area, consider an extender; and for a fixed device, consider powerline if the wiring suits it. If several people struggle to connect at once even near the router, check the service before considering a replacement router.
If Wi-Fi is poor across multiple rooms or floors, compare mesh systems rather than treating each room as a separate dead spot. Which? describes mesh as a wider, seamless home-network option; the layout and node positions still matter.
If the connection works near the router but falters at one desk, TV or console, a targeted extender or a powerline connection may address that location. Which? distinguishes a targeted extender from a whole-home mesh system; powerline suitability depends on the home’s wiring.
If streaming, gaming, work or study connections struggle when several people are online, check the broadband service as well as the router. Ofcom notes that slow performance with many connected users can come from the service itself; Which? also identifies router replacement as a route worth considering for simultaneous use.
Start by locating the problem: compare the connection near the router with the rooms where it falters, then match the equipment to the pattern.
| Priority | What to check | Your needs |
|---|---|---|
| Broadband or Wi-Fi | Check the provider’s service status and test near the router before comparing a distant room. Ofcom says Wi-Fi cannot outperform the broadband service. | If the connection is slow even near the router, I need to investigate the service before buying coverage equipment. |
| Multi-room coverage | Note which rooms and floors are affected, and where mesh units could sit. Which? describes mesh as a wider home-network solution, rather than a single-area extension. | Several rooms have weak signal, and I want coverage while moving around the home. |
| One weak area | Check that the intended extender position still receives a usable router signal. Which? describes extenders as a targeted way to increase reach. | Wi-Fi works elsewhere; it is mainly one room that needs extra reach. |
| Fixed-device connection | Decide whether the distant device needs Ethernet or local Wi-Fi, and check the intended mains sockets. Virgin Media says powerline performance depends on electrical wiring and remains limited by broadband speed. | My TV, console or desk device stays in one place, and running an Ethernet cable through the home is inconvenient. |
| Simultaneous use | Check whether slowdowns occur near the router as well as in distant rooms. Ofcom says heavy use may expose a broadband-service limitation; Which? identifies a router upgrade as another consideration for busy households. | Several people stream, game or work online at once, so I need to distinguish a shared-connection problem from weak room coverage. |
| Setup compatibility | Confirm the provider equipment, required WAN connection type and intended router or access-point mode. TP-Link says an existing-router Deco setup needs an Ethernet connection for its main unit, and gateway features differ by mode. | I want the new equipment to work with my current provider setup without losing network controls I use. |
A service fault or poor router position can look like a coverage problem. Ofcom says home Wi-Fi cannot make the incoming broadband connection faster.
Check the provider’s service status, test near the router and try a more central router position before choosing equipment.
Which? describes extenders as targeted reach increases, while mesh systems are intended for wider home coverage.
Map the affected rooms. Compare mesh if weak signal spans several rooms or floors; consider an extender if the problem is contained and its position has a usable router signal.
A replacement router needs to connect using the broadband service’s requirements. If mesh instead runs in access-point mode behind an existing router, TP-Link says Deco gateway features are unavailable in that mode.
Ask the provider for the WAN connection type before replacing its router. For mesh, confirm which device will handle routing and whether the features you need work in that mode.
Virgin Media says achievable powerline performance depends on the home’s electrical wiring and cannot exceed the broadband-service speed.
Choose powerline for an appropriate fixed location, then check the connection at the sockets where you intend to use it.
Deco is relevant when comparing mesh with an existing-router setup.
Its powerline range is relevant to a fixed device or local Wi-Fi connection using household electrical wiring.
eero is relevant when mesh equipment needs to coexist with a provider router or modem-router.
ASUS is relevant to buyers considering a third-party router in place of provider equipment.
These options cover multi-room mesh, a targeted extender and powerline connections for distant devices. Match the type to the problem before comparing individual models.

Consider this kit when a distant area needs a connection through the home’s electrical wiring as well as local Wi-Fi. Check the intended sockets and wiring: Virgin Media notes that powerline performance varies by home, so AV1300 is not a room-to-room speed guarantee. If OneMesh roaming matters, confirm that the existing router is compatible.

A three-pack mesh option to consider when weak signal affects several rooms. The title specifies dual-band WiFi 7 and 2.5Gbps Ethernet; those figures do not establish performance in a particular home. Check how the system connects to your existing modem or gateway before buying.
No image available
This three-pack is a mesh option for persistent weak signal across multiple rooms. For a Deco setup with an existing router, TP-Link says the main unit needs an Ethernet connection; router and access-point modes also differ in available gateway features. Check which mode suits your provider equipment.

Consider this extender for one weak area where the router’s signal remains usable at the proposed extender position. It is a targeted reach option, not a substitute for diagnosing poor coverage throughout the home. If EasyMesh roaming is important, check compatibility with your existing router.

This powerline kit is for a distant fixed device when a wired connection suits the room; it is not a Wi-Fi extender. The title identifies AV1300, Gigabit and pass-through sockets. Virgin Media cautions that actual powerline performance depends on the home’s electrical wiring.
Check performance near the router and the provider’s service status first. Ofcom says Wi-Fi cannot outperform the broadband connection, and slowdowns when many people are online can reflect a service limitation rather than a distant-room coverage problem.
An extender is a targeted option for one weak room or small area, provided it can receive a usable signal where it is placed. Which? describes mesh as the wider home-coverage option when weak signal affects several rooms.
It can, depending on the equipment and setup. TP-Link documents router and access-point modes for Deco with an existing router, but says the main Deco needs a physical Ethernet connection and that gateway features differ by mode. Check your exact mesh model and provider equipment.
No. Powerline uses household electrical wiring, and Virgin Media says achievable performance depends on that wiring and cannot exceed the broadband-service speed. Check it at the sockets intended for the fixed device.
Ask your broadband provider for the required WAN connection type and any setup details, then check that the replacement router can use them. ASUS UK advises confirming the WAN type with the provider before setup; a new router will not resolve an inadequate incoming broadband service.
