Check whether the incoming broadband connection or the Wi-Fi inside your home is causing the problem before buying equipment: as Ofcom explains, Wi-Fi cannot outperform the broadband service. For weak signal across several rooms, consider mesh; for one reachable weak area, an extender or wired access point may be enough. A replacement router makes more sense when one well-placed router can cover the home, while Ethernet is worth considering for fixed devices where a cable is practical.
The right equipment depends on where the connection falters and whether the devices can use a cable.
If video calls struggle while others stream or use connected devices, compare performance near the router, in the affected rooms and at different times. A problem throughout the home calls for a different response from a weak signal in one room.
If the connection works near the router but weakens in bedrooms, upstairs or beyond dense walls, look at where another Wi-Fi point could receive a usable connection. Several affected areas may call for a different layout from one weak room.
A desk computer, television or mesh node that stays in place may be able to use Ethernet. Check the available ports and cable route before adding another wireless link.
Start with the location of the problem, then choose the equipment and connection method that address it. Check how any new router or mesh gateway would work with your existing broadband equipment before replacing the main unit.
| Priority | What to check | Your needs |
|---|---|---|
| Source of the problem | Compare a wired connection, if available, or a connection close to the router with the affected room. If trouble persists near the router, check the broadband service and provider fault information before changing Wi-Fi equipment. | Calls and streams struggle throughout the home, so I want to establish whether the broadband connection is the limit. Ofcom notes that Wi-Fi cannot outperform the broadband service. |
| Several weak areas | For mesh, plan node positions around the rooms that need coverage. If you intend to connect nodes by cable, confirm that the exact system supports your proposed Ethernet backhaul layout. | Coverage drops across several rooms or floors, rather than at just one device. A multi-node layout could address those in-home gaps, but it will not increase the incoming broadband speed. |
| One weak area | Place an extender where it can still receive a usable signal from the router, not inside a complete dead zone. If Ethernet reaches the room, check whether a compatible wired access point fits the setup. | I can identify one room that needs a better Wi-Fi connection and can position an extender between that room and the router, or run a cable to it. |
| Main router | Assess whether one centrally placed router can cover the home. Before replacing provider equipment, confirm the broadband hand-off, supported operating mode and any phone or TV service requirements. | The current router or its ports are the concern, but I do not want a replacement to interrupt services that depend on the provider's equipment. |
| Fixed devices | Check for a practical cable route and suitable ports on the router and device. For a mesh node, confirm model-specific wired-backhaul support rather than assuming an Ethernet port provides it. | A work computer or television stays in one place, and I would rather connect it directly than rely on a marginal Wi-Fi link. |
A new router, extender or mesh system cannot make the incoming service faster. Ofcom distinguishes the broadband connection from the Wi-Fi connection inside the home.
Compare performance close to the router with the affected room. If both are poor, investigate the service and any provider fault before choosing in-home equipment.
Your own router or mesh gateway may need a particular modem, bridge or access-point arrangement. eero notes that some providers require their equipment for phone or TV services.
Identify your hub model, connection type and bundled services before purchase. For example, Virgin Media describes modem mode for connecting your own Wi-Fi kit, but the available arrangement depends on the hub.
An extender needs a usable wireless connection back to the router. Placing it where that connection has already disappeared does not fix the upstream link.
Try a position between the router and weak room, then test in the room. If a cable reaches it, consider a compatible access point instead.
Manufacturer Wi-Fi rates do not promise the speed a particular device will achieve. Distance, walls, connected devices and the broadband service all matter.
Choose the coverage layout, connection method and ports for your rooms and devices rather than treating a combined Wi-Fi rate as a video-call result.
These brand ranges illustrate different setup approaches; features and operating modes need checking on the exact model.
TP-Link offers Deco mesh systems, Archer routers and range extenders for different in-home coverage layouts.
eero focuses on multi-node home Wi-Fi systems, including setups that can connect compatible nodes by Ethernet.
NETGEAR offers Orbi mesh ranges with features that vary substantially by series.
Selected ASUS routers offer operating modes for setups that need a router, access point or AiMesh node.
These models cover an extender for one reachable weak area and multi-unit mesh systems for gaps across more of the home. Check the proposed placement and your provider setup before choosing; fixed devices may instead be suited to a direct Ethernet connection.

Consider this extender for one weak area if you can place it where the main router's signal is still usable. TP-Link identifies the RE220BE as a dual-band Wi-Fi 7 extender; check its position in your home rather than relying on its quoted maximum rate.

This three-pack is a mesh option to consider when weak signal affects several parts of the home. Plan where the units would go, and check how the system would connect to your existing broadband equipment and any phone or TV services.

This three-unit mesh kit is relevant when coverage is weak beyond a single router location. TP-Link describes the BE65 as a tri-band mesh system; if you plan to cable its nodes, check the supported backhaul layout as well as compatibility with your provider equipment.

This three-pack offers another multi-unit layout to consider for weak coverage in several rooms. If cabling the units is part of your plan, confirm the BE25's wired-backhaul support and required connections before purchase.

This three-pack is a mesh option for coverage across multiple rooms. The product title specifies 2.5Gbps Ethernet; check which connections are available on each unit and whether your intended wired-backhaul arrangement is supported.
Compare a connection close to the router with one in the affected room; use a wired connection as another check if you can. If the problem persists near the router, investigate the broadband service or a provider fault first. If it mainly occurs farther away, look at router placement and in-home coverage. Ofcom notes that Wi-Fi cannot outperform the broadband service.
Possibly, but confirm your hub model, broadband connection and any bundled phone or TV services before removing provider equipment. Virgin Media documents modem mode for connecting your own Wi-Fi kit on supported hubs, while eero notes that some providers require their equipment for particular services.
Ethernet is worth considering for a fixed device when a cable route and suitable ports are available. It can also connect compatible mesh nodes, but check the exact system's backhaul support. A cable to one computer or television will not, by itself, improve Wi-Fi for mobile devices elsewhere.
Not if the extender must sit where it cannot receive a usable signal from the router. For one weak room, position it between the router and that room and test the result. If Ethernet reaches the room, a compatible wired access point is another route.
