Who needs a coverage change?

Households with gaps across the home

Wi-Fi is unreliable in several rooms or across floors, particularly where people work, stream or game in different parts of the property. A fix for one spot may not address the other gaps.

People with one weak room

Most of the home connects acceptably, but one room or garden-facing area needs attention. The decision is whether an extender can receive a usable signal on its way to that spot.

Households checking the main router

Several devices are used at once for streaming, browsing, gaming or work. If performance is also poor close to the router, adding coverage farther away may not address the main problem.

What matters when choosing?

Start by checking broadband availability for your postcode with Ofcom and comparing the connection near the router with the weak room. Then choose according to where the difficulty occurs: Which? distinguishes a targeted extender from mesh coverage across a wider home.

Concern What to check Who this matters to
Several weak rooms Map the gaps and check where mesh nodes could connect to the main network and receive power. If I move between rooms while working or streaming, I need coverage beyond a single dead zone; roughly 39% of consumers would put whole-home coverage first.
One weak room Find an intermediate extender position that still receives a usable signal from the router. When the rest of the home connects well, I want to reach one room without changing the whole network; around 23% of consumers would prioritise a targeted fix.
Main-router performance Compare performance near the router and farther away; check how a replacement router would connect to your broadband equipment. If several devices struggle even close to the router, I want to address the network at its centre; roughly 23% of consumers would put main-router performance first.
Walls and floors For powerline, check the relevant sockets and whether the kit supplies Ethernet, remote Wi-Fi or both. TP-Link says its adapters must share an electrical circuit. Where thick walls make a wireless link difficult and new cabling is impractical, I would consider the existing wiring; around 15% of consumers would prioritise that route.

Avoid these buying mistakes

  • Buying coverage hardware before separating broadband from Wi-Fi

    A connection that is poor close to the main router calls for a different investigation from Wi-Fi that weakens only in a distant room.

    Use Ofcom’s postcode checker for service availability, then compare the connection close to the router with the affected room before choosing in-home hardware.

  • Putting an extender inside the dead zone

    An extender needs to receive the existing router’s signal before it can rebroadcast it. TP-Link notes that walls, metal objects and microwaves can affect that link.

    Look for an intermediate position with a usable router signal. If there is no practical position, consider different mesh-node locations, a wired connection where feasible, or powerline subject to its wiring requirements.

  • Assuming expansion devices share one mesh network

    Compatibility depends on the product family and model. ASUS says AiMesh support depends on compatible devices and firmware, while devolo cautions against treating its Magic and dLAN ranges as one combined system.

    Check the exact router, expansion unit and firmware against the manufacturer’s compatibility guidance before buying an add-on.

  • Assuming powerline works through any socket

    TP-Link states that its powerline adapters must be on the same electrical circuit; a suitable pair of socket locations cannot be assumed from their position in the home.

    Check the intended sockets against the requirements of the specific kit before choosing powerline for a remote room.

Brands to consider for home networking

TP-Link

Offers routers, range extenders, Deco mesh systems and powerline products for different coverage approaches.

  • TP-Link describes extenders for targeted gaps and Deco mesh for coverage using multiple nodes.
  • OneMesh and EasyMesh arrangements require compatible devices; TP-Link also says a powerline pair must share an electrical circuit.

NETGEAR

Its Nighthawk routers and Orbi mesh systems represent single-router and multi-node options.

  • NETGEAR describes extenders as targeted coverage expansion and mesh as a network built from multiple nodes.
  • Those approaches do not establish which particular model or node placement will cover a given property.

ASUS

Offers standalone routers, including models that can form part of a compatible AiMesh setup.

  • A compatible AiMesh router can provide a route to adding nodes later.
  • Check model and firmware support: ASUS says its compatible range extenders can serve as AiMesh nodes, not as the primary AiMesh router.

devolo

Focuses on powerline products that carry a connection over household electrical wiring to a remote location.

  • devolo presents powerline as an option where walls or floors make a wireless path difficult.
  • devolo says running its Magic and dLAN ranges in parallel does not make them one combined system.

Common questions

How can I tell whether the problem is broadband or Wi-Fi coverage?

Compare the connection close to the main router with the affected room, and check service availability for your postcode using Ofcom’s checker. If the connection is good nearby but weak farther away, in-home coverage equipment is more relevant; if it is poor beside the router too, investigate the service and main equipment before buying an extender or mesh kit.

Can I use my own router or mesh system with an ISP-supplied hub?

The connection method depends on the broadband type and exact hub. BT Business says its Smart Hub 2 can operate in bridge mode, while its Smart Hub 3 guidance distinguishes FTTP customers, who can connect a router to the optical network terminal, from non-FTTP customers for whom that hub does not support bridge mode. Check your own equipment and any ISP services you need to retain before buying.

Where should I put a Wi-Fi extender?

Put it between the router and the weak area, where it can still receive a usable router signal—not where that signal has already disappeared. TP-Link suggests a position around halfway and notes that walls, metal and microwaves can affect the wireless link.

What should I check before buying powerline adapters?

Check the intended socket locations against the kit’s electrical requirements and decide whether the remote room needs Ethernet, Wi-Fi or both. TP-Link states that its powerline adapters must share an electrical circuit; if you already own adapters, also check whether the new units belong to a compatible product family.
