If Wi-Fi works near the router but weakens in other rooms, improve the router’s position before buying equipment. An extender suits one weak area with a usable signal partway there; mesh suits several rooms where one network matters, while powerline or a wired access point may help when a wireless path is difficult. Consider replacing the router if the router itself is the problem, but check your broadband provider’s connection requirements first.
If the connection is satisfactory near the router but weak in a bedroom, kitchen or home office, start with router placement. For a remaining weak area, compare an extender with powerline or a wired access point according to the path available to that room.
If people use connected devices across the home and move between rooms, assess a multi-node mesh system. Check where each node can receive a connection from the main router or another node; the number of units alone does not establish coverage in your home.
Where walls or floors obstruct the wireless path, compare the alternatives to a wireless relay. Powerline depends on suitable electrical wiring and sockets on the same circuit; a wired access point needs an Ethernet route to the room.
Start by locating the problem, then choose equipment for the rooms and connection path involved—not just the speed figure in a product name.
| Priority | What to check | Your needs |
|---|---|---|
| Find the cause | Compare the connection near the router with the weak room. Try a more central, unobstructed router position. Ofcom notes that Wi-Fi cannot outperform the underlying broadband service. | I get a satisfactory connection beside the router, but it weakens elsewhere. If it is poor beside the router too, coverage equipment may not address the cause. |
| Size of weak area | For an extender, find a position that still receives the router’s signal; BT advises placing one roughly halfway to the weak area. For several rooms, assess mesh node positions and how they connect back to the main node. Which? distinguishes targeted extender use from whole-home mesh use. | One room needs a better connection—or several rooms and floors need coverage as people move around the home. |
| Connection path | Check whether the intended powerline sockets share an electrical circuit, as TP-Link advises. If Ethernet can reach the room, check that the chosen equipment supports access-point mode; ASUS documents an Ethernet-connected access-point arrangement. | Thick walls or distance make a wireless relay difficult, but I may be able to use suitable wall sockets or run an Ethernet cable. |
| Compatibility | Before replacing the router, confirm the broadband provider’s WAN connection type and the exact model’s supported setup, as ASUS advises. Check exact-model support before relying on a shared mesh network or settings needed by older devices. | I want to keep my existing broadband connection and connected devices working when I change the home network. |
A new Wi-Fi device cannot make the connection outperform the broadband service, as Ofcom explains. If performance is already poor near the main router, extending its signal may leave the underlying issue unchanged.
Compare the connection close to the router with the problem room, and try improving placement before choosing extra hardware.
An extender or wireless mesh node needs a connection back to the router or another node. Placing it only in the dead zone can leave that connection weak.
BT advises starting an extender roughly halfway to the weak area. Check the signal and test the result before settling on a position.
TP-Link advises that powerline adapters use sockets on the same electrical circuit. NETGEAR recommends plugging an adapter directly into a wall outlet rather than a power strip or surge protector.
Check the intended sockets and test the kit in those positions before relying on it for the remote room.
A replacement needs to support the broadband connection’s required WAN configuration. Ofcom also notes that a third-party router can be trickier to set up and may receive less support from the provider.
Ask the provider which connection type and settings are required, then check the exact router model. If retaining the ISP router, consider whether compatible equipment can operate as an access point instead.
An unfamiliar router setup can also mean more time spent configuring and troubleshooting the connection.
These brands offer different equipment routes; check the exact models and operating modes rather than assuming features apply across a range.
Offers range-extender, powerline and mesh-compatible equipment for different room-to-room connection paths.
Offers extenders and powerline equipment alongside mesh systems.
Provides documentation for mesh networking and an Ethernet-connected AiMesh access-point arrangement.
A provider-specific reference for households considering Wi-Fi discs or extenders with their BT hub.
These options cover multi-room mesh systems, a powerline kit for a remote room and a range extender for a targeted weak area. Choose the connection route before comparing models.

A three-unit mesh option to assess when several rooms need coverage. Its name specifies BE3600 and Wi-Fi 7; check the connection and operating mode required for your existing broadband setup, and plan node positions around the home’s layout.
No image available
A three-pack mesh option for coverage across several rooms. The product name specifies dual-band BE3600 and 2.5Gbps Ethernet; check the port arrangement on the exact units and your broadband gateway setup before deciding how to connect them.
No image available
Another three-unit mesh option for multiple weak rooms. Check where its units can connect to one another and confirm the operating mode needed with your existing router or broadband connection; the pack size does not determine coverage in a particular layout.
No image available
A powerline route to consider when a wireless path to the remote room is difficult. The kit name specifies AV1300 and Gigabit; check that the intended wall sockets share an electrical circuit. If a unified OneMesh network matters, confirm compatibility with your exact router.
No image available
A range extender to assess for one reachable weak area. Position it where the main router’s signal is still usable, rather than in the dead zone. If you want EasyMesh roaming, check compatibility with your exact router before relying on that arrangement.
Compare the connection close to the router with the weak room. If it works near the router but deteriorates through the home, address placement and in-home coverage first. If it is poor near the router too, check the underlying service: Ofcom notes that Wi-Fi cannot outperform the broadband connection.
Place it where it can still receive a connection from the router or previous node, not solely inside the dead zone. BT advises starting an extender roughly halfway to the weak area; test the connection there and adjust its position if needed.
Consider powerline when walls or distance make a wireless relay difficult and running Ethernet is impractical. Check that the intended sockets share an electrical circuit, as TP-Link advises, and test adapters directly in wall outlets rather than assuming the named link rate describes the connection in your room.
You can assess equipment that connects to your existing router rather than replacing it, but check the exact system’s required operating mode. A wired access point needs an Ethernet connection to the main network. If you do replace the router, confirm the ISP’s WAN connection type and the replacement model’s supported settings first.
Check the exact model and settings before changing the household network. ASUS says existing devices can still connect to traditional 2.4 GHz or 5 GHz bands on newer equipment, while some older devices may not support newer Wi-Fi features.
