First check whether the problem is Wi-Fi coverage rather than the broadband connection, and try a better router position before buying equipment. If a cable can reach the room, Ethernet and a local access point suit a fixed work or gaming area; mesh suits several weak rooms, powerline depends on the electrical circuit, and an extender needs a usable signal at an intermediate position.
If calls, coursework or a fixed computer depend on the connection in a basement bedroom or rear office, check whether Ethernet can reach that room. Ofcom identifies a direct Ethernet connection as more reliable than Wi-Fi; a wired access point can also provide Wi-Fi there.
If people move between rooms and need coverage in more than one area, consider mesh after checking where its nodes can sit. Ofcom notes that objects weaken Wi-Fi signals, while TP-Link says the primary unit of its Deco systems needs an Ethernet connection to the existing router or modem.
If drilling or a permanent cable run is unsuitable, an extender or powerline kit may be easier to place and remove. An extender still needs a usable incoming signal, and TP-Link says powerline adapters must be on the same electrical circuit. Check the tenancy agreement before making changes to the property.
Once the broadband connection is working, choose according to the number of weak rooms, the path a signal or cable can take, and which changes to the property are practical.
| Concern | What to check | Who this matters to |
|---|---|---|
| A dependable fixed-room connection | Check for an allowable Ethernet route and, if local Wi-Fi is needed, an access point that works with the existing router. | If my desk or console stays in a distant room, I need a connection that does not rely on another weak wireless hop. About 36% of consumers put fixed-room reliability first. |
| Coverage across several rooms | Check where mesh nodes can receive a workable connection and how the chosen system connects to the existing router. | When several people use different weak rooms, I need coverage beyond a single device or spot. For about 29% of consumers, multi-room coverage is the primary need. |
| Coverage without a new cable run | Before choosing powerline, confirm that both sockets are on the same electrical circuit and select a Wi-Fi-capable endpoint if the room needs wireless access. | If I cannot run Ethernet to the room, I need another path through the property that the wiring can support. This is the leading concern for about 21% of consumers. |
| One reachable weak spot | Find a position between the router and weak area where an extender can still receive a usable router signal. | For one nearby weak spot, I would rather try a portable device than alter the property, provided it can pick up the existing Wi-Fi. About 14% of consumers prioritise that simple fix. |
An extender must receive the router’s Wi-Fi before it can rebroadcast it. Walls, distance and interference may leave it with too little signal in a basement or distant rear room.
Check for a usable position between the router and weak room. If there is none, investigate a different mesh-node position, compatible powerline wiring or a wired access point.
TP-Link says its powerline adapters need to be on the same electrical circuit; adapters on different circuits will not communicate.
Confirm the circuit relationship between the router area and target room. If the room needs Wi-Fi rather than only an Ethernet connection, choose a kit with a wireless endpoint.
Extra Wi-Fi equipment cannot resolve a provider outage or increase the capacity of the broadband service. Heavy use by other devices can also affect what you experience in a room.
Follow Ofcom’s advice to check for service problems and interference, then compare the connection near the router with a wired Ethernet connection where possible.
A wired route may involve changes to a rented property. The London Borough of Redbridge advises private tenants to obtain their landlord’s permission for home improvements.
Review the tenancy agreement and ask in writing before drilling or making other permanent changes. If a fixed cable route is not permitted, consider equipment that can be placed and removed without those changes.
Its Deco mesh systems, range extenders, powerline adapters and access-point configurations cover several of the routes discussed here.
Its Orbi range is relevant if you are considering mesh while retaining a broadband provider’s gateway.
Its UniFi access points are relevant where a planned Ethernet installation is possible.
These mesh systems, powerline Wi-Fi kit and range extender suit different room-coverage situations. Choose the connection route before choosing a model: a usable wireless path, suitable electrical circuit or permitted cable run remains decisive.

Consider this mesh set when several rooms need Wi-Fi and there are workable positions for three units. Confirm the BE22 setup requirements with your existing router and assess the links between the planned node positions.

Consider this kit when a new Ethernet run is impractical but the target room needs a wireless endpoint. TP-Link says powerline adapters must share an electrical circuit; confirm the relevant sockets before choosing this route. AV1300 is a product designation, not a promise of speed in your home.

Consider this dual-band BE3600 mesh system for several weak rooms, subject to suitable positions for its units. Its product name specifies 2.5Gbps Ethernet; check how the RBE373 connects to your existing broadband gateway and which operating modes it supports.
No image available
Consider this extender for one weak spot if it can be placed where the router signal is still usable. It is not a substitute for a viable incoming connection; check that placement and the intended setup with your router before buying.

Consider this three-unit mesh set when coverage is needed in several rooms. Check the BE25 connection and operating-mode requirements with your existing router, as well as practical node positions; confirm any speed specification for this variant before relying on it.
Check the connection and router position first. Ofcom advises checking for broadband problems and Wi-Fi interference; comparing a wired connection near the router with the weak room can help distinguish a coverage problem from a problem affecting the service itself.
Some mesh systems can, but the connection and operating mode depend on the model. TP-Link says the primary unit of its Deco systems must connect to the existing router or modem by Ethernet; check the chosen system’s instructions for router or access-point mode and any features affected by that choice.
Not if the relevant sockets are on different electrical circuits, according to TP-Link’s powerline guidance. The router-side adapter also needs an Ethernet connection to the router, so check both the wiring arrangement and the connection you need in the distant room.
Check your tenancy agreement and ask the landlord in writing before making permanent changes. The London Borough of Redbridge advises private tenants to obtain permission for home improvements; that guidance should not be treated as a single rule for every tenancy across the UK.
