Test the connection at the router by Ethernet before buying equipment: if that connection is also poor, a Wi-Fi coverage purchase is unlikely to address the underlying problem. If wired performance is sound but several rooms have weak Wi-Fi, consider mesh, preferably with a wired connection between nodes where practical. For one weak area, consider a well-placed extender or a wired access point; powerline depends on the home’s wiring, while a replacement router calls for service-compatibility checks.
If calls falter in an upstairs or distant work room, compare that room’s connection with an Ethernet test at the router. Ofcom recommends a wired test when you need to separate broadband performance from Wi-Fi performance.
When phones and laptops move between floors, map every weak area before choosing a single-room extender. Ofcom distinguishes extenders from mesh systems and notes that extenders can affect speed and responsiveness.
A wireless extender or powerline kit may reach a remote room without a new Ethernet run. Check where the extender can receive the existing signal, or test powerline in the intended room: walls and electrical wiring make the choice home-specific.
Start by locating the problem, then choose a connection route for the rooms affected rather than relying on a headline Wi-Fi speed.
| Priority | What to check | Your needs |
|---|---|---|
| Broadband or Wi-Fi? | Test a device connected to the router by Ethernet. Check provider status and whether heavy household downloads coincide with the problem; Ofcom recommends considering both the wired result and other network activity. | I want to know whether the connection arriving at the router is poor before buying equipment for another floor. |
| Number of weak rooms | Map the affected rooms and check router and proposed node positions. Consider mesh for several coverage areas; a wireless extender needs usable signal at its own location. Ofcom notes that extenders can affect speed and responsiveness. | Several floors need Wi-Fi, and devices move between them—or there is just one weak room to reach. |
| Work-room connection | Check whether Ethernet can reach the desk or an access point. TP-Link describes Ethernet backhaul between Deco nodes as faster and more stable than a wireless node link; its RE605X can use a wired connection in access-point mode. | Calls in a fixed work room matter more to me than an advertised maximum wireless rate. |
| Cable alternatives | If running Ethernet is impractical, assess extender placement or test powerline on the home’s electrical wiring. A powerline product’s advertised rate does not establish the result in a particular room. | I need to reach a distant room without routing a new cable through the home. |
| Existing equipment | Before replacing a router, confirm the broadband connection method and any provider equipment or telephone-service requirements. For mesh or an extender, check the exact router and model requirements for any advertised roaming features. | I want new Wi-Fi equipment to work with the broadband setup and devices I already use. |
A coverage device cannot resolve a poor connection already present in a wired test at the router. Household traffic can also affect what you experience during a call.
Use an Ethernet-connected device for the initial test, check provider status and note whether heavy downloads coincide with the problem before choosing Wi-Fi hardware.
Walls, ceilings and node placement affect the signal in individual rooms, so a product’s stated coverage area does not establish the result in a three-floor home.
Identify the rooms that actually need coverage and plan where each node could sit. If a cable can reach the work area, consider a wired access point or supported wired mesh backhaul.
An extender must receive the existing Wi-Fi signal before it can relay it. Ofcom warns that extenders can affect connection speed and responsiveness.
Place it where the router’s signal is still usable, following the model’s placement guidance, then test the connection in the target room.
A retail router may need connection settings or existing provider equipment to remain in place. Changing the router alone also does not resolve a poor wired broadband result.
Confirm the service connection method, any modem or ONT arrangement, telephone-service needs and support arrangements before choosing a replacement.
Allow time to configure and troubleshoot the connection if you change the equipment that connects to the broadband service.

Deco mesh systems and RE-series extenders offer different ways to reach weak rooms.
The Orbi 770 series is presented by NETGEAR as a whole-home mesh system.
Amazon presents eero 6+ as a mesh Wi-Fi router for connected household devices.
Magic powerline adapters provide a route to remote rooms using the home’s electrical wiring.
The Wi-Fi Extender 2600 is an example of extending an existing network to a contained weak area.
These options cover mesh systems for several weak areas, a powerline kit for a room that is difficult to cable, and an extender for a more contained weak spot. Choose the connection route first, then check the exact equipment against your broadband setup and room layout.

Consider this three-unit mesh option when several rooms or floors need coverage. Tri-band Wi-Fi 7 and BE9300 are stated product specifications, not a promise of speed or coverage through your walls. Check how the system will connect to your existing broadband equipment.

This three-pack is another mesh option for several weak rooms. BE3600 and Wi-Fi 7 identify the stated variant; neither establishes the connection you will receive in a particular work room. Confirm its connection requirements against your broadband equipment before choosing it.

The three-unit format is relevant when coverage is needed across several areas. The stated variant is dual-band BE3600 with 2.5Gbps Ethernet; actual wireless results depend on the building and connected devices. Confirm what modem or gateway your broadband setup requires.

Consider powerline when running Ethernet to a remote room is impractical. AV1300 is a stated product rating, not the speed the home’s wiring will deliver; test the kit in the intended room. If OneMesh roaming matters, confirm compatibility with your exact router.

This extender is a route to consider for one weak area, provided it can sit where the router’s signal remains usable. Wi-Fi 7 and BE3600 identify the stated variant, not the result in the distant room. Check exact-router compatibility before relying on EasyMesh roaming.
Test a computer or tablet connected to the router by Ethernet first, as Ofcom recommends for a clearer broadband-speed test. If that connection is also poor, check provider status and household traffic before buying coverage equipment; if it is sound while distant rooms struggle, focus on the in-home connection.
It may help if it can be placed where it still receives usable Wi-Fi from the router. Ofcom warns that extenders can affect speed and responsiveness, so test the target room; where Ethernet reaches that floor, a compatible wired access point is another route.
Consider mesh when several rooms or floors need coverage and devices move between them; an extender is a more targeted option for one weak area. If you can cable between compatible mesh nodes, TP-Link describes its Deco Ethernet backhaul as faster and more stable than a wireless connection between those nodes.
Check the exact service connection method, required modem or ONT, connection settings and any telephone-service dependency before replacing it. If you keep the provider router, a wired access point may instead add Wi-Fi where a cable can reach.
Do not treat the advertised rate as a measured result in your rooms. devolo describes powerline as using household electrical wiring, so test the connection at the intended sockets before relying on it for a work room.
