Choose an extension method according to the connection available between the supplied router and your bedroom, rather than relying on a kit’s advertised Wi-Fi rate. An extender needs a usable signal where it is placed; some mesh systems, including the TP-Link Deco and MERCUSYS Halo ranges discussed here, need their main unit connected to the router by Ethernet; powerline depends on the property’s wiring. None of these options can improve a slow broadband service, and any router connection or cable route may need agreement from the person or household in control.
If Wi-Fi works near the supplied router but fades in your bedroom, a removable extender may be worth considering only if a socket between the router and bedroom still receives a usable signal. TP-Link advises placing an extender within range of the router.
If walls or floors obstruct the wireless connection, check whether powerline adapters can connect through the intended sockets or whether a permitted Ethernet route is possible. A basement location alone does not establish that a powerline link will work.
If several residents need better coverage, compare how each system connects to the supplied router and where its units can be placed. TP-Link Deco and MERCUSYS Halo systems described here require a wired connection for the main unit.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| A usable wireless link to one bedroom | Test reception at possible hallway or landing sockets. Check that the device can repeat the existing Wi-Fi. | If I need to reach one weak bedroom without adding a cable, I want a socket where the router’s signal still works. Around 29% of consumers put a single-room wireless gap first. |
| Getting through thick walls or to a basement | Identify the router-side and bedroom-side sockets. Check the kit’s circuit requirements and whether it provides Wi-Fi at the far end. | When floors or walls make a wireless link doubtful, I need to know whether the intended sockets can support powerline or a cable route is permitted. Around 29% of consumers prioritise reaching a wall- or floor-blocked room. |
| Coverage for several rooms | Check whether the main mesh unit needs Ethernet to the router and whether the units can be placed where they retain a useful link. | If several housemates need coverage, I want to coordinate the equipment, placement and connection to the shared router. Around 21% of consumers put coverage across multiple rooms first. |
| Setup that fits shared-property arrangements | Confirm who can approve a router connection, device placement and any cable through shared space. Check the exact device’s operating modes. | If I have limited control over the shared network or property, I need an arrangement the household will allow, even if more than one room has poor Wi-Fi. Around 21% of consumers prioritise setup flexibility and permission. |
An extender has to receive the existing Wi-Fi before it can repeat it.
Check reception at an intermediate socket and follow the placement guidance for the exact device.
TP-Link Deco and MERCUSYS Halo systems described here require their main unit to connect by wire; they are not wireless repeaters for an existing router.
Check the exact system’s connection diagram and whether its access-point mode fits the household’s router arrangement.
Powerline depends on the property’s electrical arrangements. TP-Link’s basic setup guidance calls for at least two units on the same electrical circuit, and filtered power strips can disrupt the signal.
Check the intended sockets and the kit’s requirements. TP-Link advises plugging its powerline adapters directly into wall sockets rather than power strips.
Building materials, the connection between devices and the supplied broadband service all affect the connection available in the room.
Choose a route that can connect in your property, and treat advertised rates as specifications rather than measured results for your bedroom.
These brands cover different equipment routes; setup requirements apply to the named product lines or models, not automatically to every product from each brand.
Its UK range includes wireless extenders, Deco mesh systems and Wi-Fi powerline equipment.
Its Magic powerline Wi-Fi kits are designed to carry a connection over a home’s electrical wiring to another room.
The EAX12 is a wireless extender for adding coverage where a usable wireless link to the router remains.
The RP-AX58 is relevant when comparing a wireless extender with an Ethernet-fed access point.
Halo mesh systems offer an access-point mode for households that can connect the main unit to an existing router.
The products below cover mesh, wireless-extender and powerline Wi-Fi routes for improving coverage beyond the supplied router.
No image available
A mesh option to consider when several rooms need coverage; check how its main unit connects to the supplied router.
The product name specifies dual-band BE3600 Wi-Fi and 2.5Gbps Ethernet.
No image available
Consider this route for a weak bedroom connection if an intermediate socket still receives usable Wi-Fi from the router.
The product name identifies it as a BE3600 Wi-Fi 7 range extender. An extender cannot repeat a signal it does not receive.
No image available
Consider a multi-unit mesh route when several rooms need coverage and the household can connect the main unit to the existing router by Ethernet.
The product name specifies a three-pack. TP-Link says the main Deco unit needs a wired connection and does not support repeater mode.
No image available
Consider powerline Wi-Fi if walls or floors make a wireless link difficult and the intended sockets can establish a working connection.
The product name identifies an AV1300 Gigabit powerline Wi-Fi kit. TP-Link’s basic setup calls for adapters on the same electrical circuit and recommends direct wall-socket connections.
No image available
Consider this multi-unit mesh route if several rooms need coverage and a wired connection from the main unit to the supplied router is possible.
The product name specifies a three-pack and tri-band Wi-Fi 7. TP-Link says the main Deco unit needs an Ethernet connection and does not support repeater mode.
Compare the connection near the supplied router with the connection in the bedroom. Ofcom explains that better in-home Wi-Fi cannot outperform the underlying broadband service; if both locations struggle, ask whoever controls the account to check the service before buying extension equipment.
Not as the first unit in the TP-Link Deco and MERCUSYS Halo systems discussed here: both manufacturers say their main unit needs a wired connection. Additional units link within their mesh system, subject to placement, so check the instructions for the exact system before buying.
Check the intended sockets and the exact kit’s requirements. TP-Link’s basic setup guidance calls for at least two adapters on the same electrical circuit; it also advises using wall sockets rather than filtered power strips. Wiring and appliances can affect the connection in a particular property.
Do not assume that a router connection, device placement or cable route is permitted. Check the proposed setup with the person or household that controls the network and property before buying or installing equipment.
No: these devices can change how the connection reaches rooms inside the property, but they cannot improve the underlying broadband service. Ofcom advises that Wi-Fi cannot outperform that service, so check the connection near the supplied router as well as in the bedroom.
