When broadband works near the router but Wi-Fi struggles in distant rooms, choose equipment for the rooms that need a connection rather than changing the broadband package straight away. Use an existing practical Ethernet route for fixed devices or wired Wi-Fi points; consider mesh for several weak rooms, an extender for one spot where it can receive a usable signal, or powerline only if the intended wall outlets can support a link on the same electrical circuit. Ofcom notes that brick internal walls can make whole-home Wi-Fi harder to achieve, so placement and the building layout matter whichever route you choose.
If your desk is far from the router, check whether Ethernet can reach it before relying on another wireless hop. A wired connection can serve the desk directly or feed a Wi-Fi point nearby; TP-Link’s guidance also identifies wired backhaul as useful where floors or thick walls separate mesh units.
When coverage drops across more than one floor or room, consider where multiple Wi-Fi points could go. Ofcom notes that brick internal walls can weaken coverage; each point still needs a workable connection back to the network.
For a single weak spot, check whether an extender can receive a usable router signal at its intended position. If considering powerline instead, TP-Link’s installation guidance calls for adapters on the same electrical circuit and plugged directly into wall outlets.
Work out whether the problem follows a room, a device or the broadband connection itself. Then match the extension method to the available cable route, router setup and number of weak rooms.
| Priority | What to check | Your needs |
|---|---|---|
| Where the fault occurs | Compare the connection near the router and in the problem room. Check the provider’s service status and whether heavy use by other devices coincides with the trouble; Ofcom advises checking for data-heavy activity on the network. | Calls or streams fail in one room, but I need to know whether extending indoor coverage will address the cause. |
| Floors and walls | Identify each weak room and possible positions for additional Wi-Fi points. Ofcom notes that signals weaken through objects and that brick internal walls can make whole-home coverage harder. | Several rooms are separated from the router by floors or solid walls, so one remote-room connection may not cover everything I use. |
| Existing Ethernet | Check for a practical cable route to a fixed device or Wi-Fi point. For compatible Deco mesh systems, TP-Link says Ethernet backhaul avoids the bandwidth loss of a wireless hop between nodes. | A work desk, television or console stays in one place, and I can use an existing or straightforward cable route. |
| Router setup | Check the chosen system’s router and access-point modes and which device will assign IP addresses. TP-Link says an existing router handles that task when Deco runs in access-point mode, while some Deco app features then become unavailable. | I want better Wi-Fi while keeping my current broadband router and the network functions I use. |
| One-room extension | Check the router’s signal where an extender would be placed, not just in the dead zone. If that position cannot receive a useful connection, consider a practical wired route or check powerline feasibility instead. | Only one room needs everyday connectivity; I do not need additional Wi-Fi points across the whole property. |
| Powerline outlets | Check that the intended outlets are on the same electrical circuit and allow direct wall-socket use. TP-Link says its advertised powerline link rate is not the actual data-transfer speed. | Running Ethernet is impractical, but the router and distant room both have suitable wall outlets. |
An extender depends on the connection it receives, so its position matters as much as the location of the dead zone.
Check for a usable signal at the proposed outlet. If there is none, investigate a practical wired connection or whether powerline can link the intended rooms.
TP-Link says the advertised link rate is not actual data-transfer speed and that results depend on the network environment. Its guidance also says adapters on different electrical circuits will not communicate.
Check the intended circuit and use direct wall outlets, as TP-Link instructs. Test the kit in the rooms where it will be used before depending on that connection.
Keeping an existing router in charge of the network changes how a mesh system should be configured. TP-Link says its Deco access-point mode leaves IP-address assignment to the existing router and makes some app features unavailable.
Check the exact model’s supported modes and decide which device must handle routing and any network-management features you need.
A connection problem affecting devices beside the router calls for a different check from Wi-Fi trouble confined to a distant room. Other data-heavy activity can also affect use of the connection, as Ofcom advises.
Compare locations, check the provider’s service status and note what other devices are doing when the problem occurs. Choose an indoor extension route only if it addresses the problem you observe.
These brand ranges illustrate different equipment routes; check the exact model and configuration rather than assuming every product in a range works the same way.
Its Deco range covers multi-node mesh, while its powerline range offers another way to reach a remote room through home electrical wiring.
NETGEAR presents Orbi as a multi-node whole-home mesh range for buyers considering coverage across several rooms.
BT’s Broadband Extender Flex 1000 documentation provides an example of using home electrical wiring to extend an Ethernet connection.
These options focus on multi-room mesh systems and a powerline Wi-Fi kit for a distant room. Choose between those routes after checking your existing router arrangement, possible node positions and, for powerline, the intended electrical circuit.

A three-unit mesh option to consider when several rooms need Wi-Fi. Plan positions that maintain a connection between units, and check the BE22’s operating mode against your existing router before buying.

This dual-band mesh three-pack is an option for several weak rooms; its name specifies 2.5Gbps Ethernet. Check the ports and operating mode needed for your devices and existing router, and do not treat stated coverage as a promise for your building.

Consider this three-unit mesh system if Wi-Fi is weak in more than one room. Confirm how the BE25 connects to your modem or router and whether its available operating mode preserves the network functions you need.

This kit offers a powerline route when running Ethernet to a distant room is impractical and that room also needs Wi-Fi. TP-Link says powerline adapters must share an electrical circuit and use direct wall outlets; its AV1300 link-rate label is not a measure of actual transfer speed.

This tri-band three-pack is another mesh option for several weak rooms. Check its Ethernet connections, backhaul configuration and operating mode against your intended layout and existing router; the BE9300 designation does not predict room-by-room speed.
Not before checking where the problem occurs. Compare the connection near the router with the upstairs room, check the provider’s service status and note whether other devices are using the connection heavily. A problem confined to a distant room points towards an indoor coverage check; trouble beside the router needs further investigation before you buy extension equipment.
It can if the exact system supports a suitable setup. TP-Link documents Deco access-point mode for keeping the existing router responsible for routing and IP addresses, but says some Deco app features are then unavailable. Check the chosen model’s mode and the functions you need before purchase.
The floor alone does not determine whether they will link. TP-Link says its powerline adapters need outlets on the same electrical circuit and should be plugged directly into wall sockets rather than power strips. Check the intended outlets and test the connection in the rooms where you plan to use it.
