Check whether calls struggle only in distant rooms or also near the router: as Ofcom explains, Wi-Fi cannot outperform the broadband service feeding it. Try router placement or a well-positioned extender for one weak area, and consider mesh for several rooms; replace the router only after checking your connection type, or consider a broadband upgrade if the incoming connection is the limiting factor.
If meetings or classes falter while others stream or download, check whether the difficulty occurs near the router as well as in other rooms. Ofcom advises considering other activity on the connection when investigating broadband and Wi-Fi problems.
If Wi-Fi works near the router but struggles in a bedroom or study, router position and the signal available at a proposed extender location matter. TP-Link advises placing an extender between the router and the weak area, where it can still receive a usable signal.
If an ageing or unreliable router prompts a change, identify how broadband enters the home before choosing hardware. DrayTek distinguishes routers with VDSL modems for FTTC connections from Ethernet-WAN arrangements used with FTTP equipment.
Start by locating the bottleneck, then choose equipment for the rooms and connection type involved rather than treating every failed call as a coverage problem.
| Priority | What to check | Your needs |
|---|---|---|
| Connection or Wi-Fi | Compare performance near the router with the problem room. Test at different times over several days, as Ofcom advises; note whether other household activity coincides with slowdowns. | Calls fail even beside the router, or several people need the connection at once. I need to establish whether the broadband service needs attention before buying more Wi-Fi hardware. |
| One weak area | Try a better router position first. For an extender, check that a position between the router and weak room still receives a usable signal; TP-Link cautions against placing it in the dead zone. | Wi-Fi is usable elsewhere, but I need a connection in one distant bedroom or study. An extender is worth considering only if there is a workable place to install it. |
| Several weak rooms | Plan where mesh nodes could sit and whether Ethernet cabling is practical. TP-Link says Deco can connect to an existing router by Ethernet; mesh still cannot increase incoming broadband speed. | Work, learning or streaming happens across several rooms or floors. I need broader in-home coverage, not merely a stronger signal in one spot. |
| Router compatibility | Identify FTTC/VDSL, FTTP with an optical network terminal (ONT), cable or another connection type. Confirm the required modem or WAN interface, provider settings and any digital-landline requirements before replacement. | If I replace the supplied router, it must connect to my actual broadband setup without overlooking a phone service or a provider setting. |
| Broadband capacity | If performance is poor close to the router during shared use, compare repeated test results with the service and address-specific upgrade options. Ofcom notes that improving Wi-Fi cannot make it faster than the broadband service. | When calls, streams and downloads compete even near the router, I need to consider the incoming connection; faster broadband alone will not fix a distant Wi-Fi dead zone. |
Mesh can address weak Wi-Fi around the home, but it cannot raise the speed delivered by the broadband service. A slow connection near the router needs a different investigation.
Follow Ofcom’s advice to test at different times over several days, then compare the router area with the room where calls fail.
A third-party router may need a VDSL modem for an FTTC setup or an Ethernet WAN connection for FTTP equipment. Replacing a provider hub can also affect how a digital landline is connected and supported.
Identify the installed connection equipment and confirm the provider’s settings, telephone arrangement and support requirements before ordering.
An extender needs a usable signal from the router before it can serve the weak area; placing it where the original signal fails undermines that route.
TP-Link recommends a position roughly between the router and the weak area. If a suitable wireless position is impractical, check whether a wired access-point setup is possible.
Wall materials, interference and node positions affect the signal in a particular home. A product’s coverage claim does not establish how it will perform in every room.
Plan possible node positions around the rooms that actually need service, then assess the result in those rooms rather than choosing by an advertised coverage figure alone.
Deco mesh systems and range extenders offer different approaches to multi-room coverage and a contained weak area.
Its Orbi mesh systems and mesh extenders represent different coverage arrangements, so compare the exact model and the area that needs service.
AiMesh and ZenWiFi are relevant when planning a mesh layout, particularly where Ethernet can run between nodes.
Its UK router information is useful for distinguishing broadband access types before considering a third-party replacement.
These options include mesh kits for several weak rooms and a range extender for one limited weak area. Check the broadband connection first: none of these devices can increase the speed supplied by your broadband service.

A three-unit mesh kit to consider when several rooms need Wi-Fi. Check where each unit could sit; the BE3600 designation does not establish call quality or coverage in a particular home.
No image available
A three-pack mesh option for coverage across multiple rooms, with 2.5Gbps Ethernet stated in its product name. Check the connection equipment it needs and where the units can be placed; the Ethernet figure is not a promise of broadband or Wi-Fi speed.
No image available
Three mesh units provide a layout option for several weak rooms. Plan node positions and check that app-based setup suits your household; the kit cannot remedy an inadequate incoming broadband connection.

A three-pack mesh option for a home with several rooms to cover. Check the exact connection and setup requirements alongside possible node positions; the BE9300 designation does not establish performance in your rooms.
No image available
A range extender to consider for one contained weak area, rather than a three-unit mesh kit. Place it where it can still receive the router’s signal; check compatibility with your router before relying on EasyMesh roaming.
Compare performance near the router with the affected room, testing at different times as Ofcom advises. If the connection struggles near the router too, investigate the broadband service; if only distant rooms struggle, consider placement, an extender for one weak area or mesh for several rooms.
Identify whether your connection uses FTTC/VDSL, FTTP equipment with Ethernet, cable or another arrangement. DrayTek distinguishes the modem needs of FTTC from Ethernet-WAN FTTP setups; also confirm provider settings, digital-landline connections and support arrangements before disconnecting the supplied hub.
A compatible system may connect to the existing router: TP-Link says Deco can do so by Ethernet. Check the system’s operating modes and decide which device should handle routing before setup.
Put it between the router and the weak area, where it still receives a usable router signal, rather than inside the dead zone. TP-Link recommends roughly halfway placement; walls and interference may mean adjusting that position in your home.
