Check whether the connection also struggles near the router before buying equipment for a distant room: Ofcom notes that Wi-Fi cannot outperform the underlying broadband service. If the problem is confined to one room, an extender needs a usable signal at its installation point; powerline or a wired access point offers another route when the wireless path is difficult. Consider mesh for several weak rooms, or a router change if the existing router is the wider problem.
If calls, study, streaming or gaming work near the router but struggle in one fixed room, compare a targeted extender with a powerline endpoint or wired access point. Which? distinguishes an extender for a particular weak area from mesh for broader coverage.
When upstairs rooms, distant corners or several rooms in use need coverage, compare a multi-node mesh system with a planned wired or powerline route rather than assuming one plug-in extender will reach everywhere.
If disconnections or slow performance occur across the home, diagnose the service and router before adding coverage equipment. Ofcom advises checking household Wi-Fi use, while Which? discusses router replacement when several people use the connection at once.
Start by comparing the connection near the router with the distant room. Then choose between extending a usable wireless signal, distributing a connection across several rooms, or bringing a wired or powerline connection closer to where it is needed.
| Concern | What to check | Who this matters to |
|---|---|---|
| One-room reach | For an extender, find a position between the router and room that still receives a usable signal; check whether a separate network name would matter to you. | I want coverage at one desk without changing the whole network, provided an extender can receive the router signal along the way. Around 25% of consumers put this targeted reach first. |
| Several rooms | Identify the weak rooms and possible mesh-node positions; check how the main unit connects to the existing gateway. | If I move between rooms or several areas need Wi-Fi, covering only one dead spot will not meet my needs. Broader coverage comes first for around 33% of consumers. |
| A fixed device | Check whether Ethernet can reach the desk or device; if not, test whether powerline works in the intended sockets. | For a workstation, TV or games console that stays put, I would rather assess the connection feeding that location than rely on a stronger Wi-Fi indicator alone. Around 17% of consumers prioritise this fixed-location need. |
| Walls and floors | Assess obstacles and cable routes; compare mesh-node placement with a powerline Wi-Fi endpoint if running Ethernet is impractical. | Dense walls or a floor between the router and my room make the wireless route difficult, but I cannot readily install a cable. Working around those obstacles is the primary concern for around 17% of consumers. |
| Service or router faults | Compare performance near the router and in the distant room, and check the provider's service status before replacing equipment. | If several devices struggle even near the router, I need to identify the cause before buying a coverage add-on. Around 8% of consumers place that diagnosis first. |
Ofcom explains that Wi-Fi cannot outperform the broadband service. If performance is poor near the router as well as in the distant room, an extender or mesh system may leave the underlying problem untouched.
Compare both locations, check the provider's service status and report persistent service faults before choosing new hardware.
An extender rebroadcasts the connection it receives, so its position matters. NETGEAR recommends starting roughly halfway between the router and weak area.
Test the intended room from that position. If there is no workable intermediate spot, assess a powerline or Ethernet-backed route instead.
TP-Link says the main Deco unit needs a physical Ethernet connection and cannot act as a wireless repeater for an existing router.
Check the exact ISP gateway, available ports and supported router or access-point mode before planning a Deco installation.
Walls and floors affect Wi-Fi, while powerline results depend on the home's electrical installation. A stated maximum rate cannot tell you how a particular room will perform.
Test the proposed equipment in its intended positions and check the seller's return terms before buying.
Its extender, Deco mesh, router and powerline lines span both targeted-room and broader-network setups.
Nighthawk extenders and Orbi mesh systems address different scales of in-home coverage.
Magic powerline products are relevant when a difficult wireless path makes an endpoint in another room worth considering.
A mesh-focused option to examine when coverage across several rooms matters more than one standalone extender.
These choices cover targeted Wi-Fi extension, powerline access to another room and mesh systems for wider coverage. Match the route to the problem you observe before comparing individual models.

Consider this range extender when one distant room is weak but a position between it and the router still receives a usable signal.
The product name identifies the RE220BE model and BE3600 Wi-Fi 7 designation. Check compatibility with your router and current firmware support for this exact model.
No image available
Consider a powerline kit when the wireless path to the room is difficult and suitable mains sockets are available at both ends.
The kit's name identifies the TL-WPA8631P KIT and AV1300 Gigabit designation. Test performance in the intended sockets, and check the plug version and firmware support before purchase.
No image available
Consider this mesh system if the distant room is one of several areas that need coverage.
The named variant is a dual-band BE3600 three-pack with 2.5Gbps Ethernet. The listing identifies a European version, so check the supplied plug, your ISP gateway setup and exact-model support arrangements.
No image available
Consider this three-pack when several rooms need coverage and the main unit can connect by Ethernet to the modem or router.
TP-Link says the main Deco cannot wirelessly repeat an existing router. The listing identifies a Deco BE22 (EU) V1; check the plug, ISP gateway configuration and firmware support for that variant.
No image available
Consider this Deco three-pack when the coverage problem extends beyond one room.
Confirm the included units, connection requirements, ISP gateway compatibility, plug version and current firmware support for the exact BE25 variant before buying.
Compare the connection near the router with the distant room. If both struggle, check the provider's service status and ask about persistent faults before buying coverage equipment. Ofcom's broadband checker shows service availability at a postcode; it does not diagnose room-by-room Wi-Fi.
Start somewhere that still receives the router's signal, rather than in the room where it disappears. NETGEAR suggests a position roughly halfway towards the weak area; test the connection in the room you actually need to use.
It may, but the connection and operating mode depend on the equipment. TP-Link says Deco can operate with an existing router in router or access-point mode, while its main unit needs a physical Ethernet connection and cannot act as a wireless repeater. Check the exact ISP gateway's configuration options before purchase.
Check support information for the exact extender, router or mesh model, including how it receives updates and how long support is expected to continue. The National Cyber Security Centre advises avoiding devices that are no longer supported, or whose support period will end soon, where possible.
