Check the broadband service and test near the router before buying: Ofcom says Wi-Fi cannot outperform the incoming connection. For weak coverage in several rooms, consider mesh; for one weak room with a usable signal midway from the router, consider an extender. A router replacement makes more sense when the existing router is the local bottleneck, while Ethernet suits a fixed calling desk where a cable can be routed safely.
The number of affected rooms, whether you move during calls and whether a cable can reach your desk point towards different solutions.
If calls falter across floors or as you move around, a multi-node mesh system is worth considering. Ofcom describes mesh as a way to improve coverage around the home; node placement and the walls between nodes still matter.
If the rest of the home works well, an extender may address that room without replacing the whole setup. It needs a position between the router and the weak room where it can still receive a usable signal.
If a cable can be routed safely to the desk, a direct Ethernet connection removes the local Wi-Fi link from that device’s connection. Ofcom recommends connecting a computer directly to the router by Ethernet when checking broadband speed.
Start by separating a broadband fault from weak Wi-Fi, then map the rooms where calls happen. The right equipment depends on where the signal fails and whether you can place another unit or run a cable.
| Priority | What to check | Your needs |
|---|---|---|
| Connection diagnosis | Compare calls or connection tests near the router and in the affected room at different times. Check the provider’s service status. Ofcom advises testing over several days; Wi-Fi cannot outperform the broadband service. | If calls also fail close to the router, I want to check the service before buying equipment for another room. |
| Room coverage | Try a central, elevated router position first. Note the walls and floors between it and calling rooms. For one weak room, look for a usable midpoint for an extender; for several, consider where mesh nodes could go. | Calls need to work in the rooms I actually use, not just beside the router. |
| Moving during calls | Check whether a mesh system uses one network name and how its nodes connect. For an extender, confirm roaming features with the exact extender and existing router rather than assuming they will work together. | I move between rooms during calls and do not want to change Wi-Fi networks manually. |
| Router capacity | If the router appears to be the local bottleneck, check its placement, connected devices and available traffic controls. Before replacing provider equipment, confirm the connection type and required router settings. | Other people use the connection during my calls, but I do not want to replace the router if the broadband service is the limiting factor. |
| Wired options | Check whether a cable can reach a fixed desk safely. For mesh, confirm Ethernet-backhaul support on the exact units before planning cables between nodes. TP-Link describes wired backhaul as an option for compatible Deco systems. | At a fixed desk, I would use a cable if the route is practical; across floors, I may be able to connect mesh nodes through existing Ethernet runs. |
A mesh system or extender cannot fix an incoming broadband fault or an area outage. Ofcom also notes that Wi-Fi cannot outperform the broadband connection.
Compare the affected room with a position near the router at different times, check the provider’s service status and raise a persistent service fault with the provider.
An extender rebroadcasts the signal it receives. If that signal is already weak at the socket, moving the extender closer to the calling room may not help.
Choose a position between the router and the room with a usable router signal, then test calls in the room itself.
Ofcom explains that Wi-Fi weakens through objects. A coverage figure cannot account for the particular walls, floors and node positions in your home.
Map the rooms where calls take place and plan where each unit could receive a good connection before choosing a pack size.
A new router still depends on the incoming broadband service and needs to work with the connection used in your home.
Confirm the required connection settings and ports before buying, and keep the existing router available until the replacement setup works reliably.
These ranges illustrate mesh, extender and router features to check; a brand’s feature descriptions do not establish how a device will perform in your home.
Its Deco range includes multi-unit home mesh systems.
Its home-networking range includes mesh systems and extenders for use with an existing router.
Its router range includes AiMesh-compatible models and configurable traffic controls.
These Joybuy options are three-unit mesh systems to consider when calls are affected in several rooms. They do not replace the checks for a service fault, a single weak room or a practical wired connection.

For calls affected in several rooms, this three-pack provides multiple units to position around the home. Its name specifies BE3600 and Wi-Fi 7; check node placement against your walls and floors, and confirm the exact wired-backhaul setup if you intend to cable the units.
No image available
This three-pack is a mesh option for placing units near calling rooms on different floors. The title specifies tri-band Wi-Fi 7 and BE9300, not a guaranteed result in your home; confirm Ethernet-backhaul options for this variant if you plan to connect its units by cable.

This three-pack is another option for positioning mesh units across several calling rooms. The title specifies dual-band WiFi 7, BE3600 and 2.5Gbps Ethernet; confirm whether its satellite ports support the wired-backhaul arrangement you want rather than assuming that an Ethernet port guarantees it.
Yes. Compare the connection near the router with the affected room at different times, and check the provider’s service status. Ofcom says Wi-Fi cannot outperform the broadband service, so another Wi-Fi device will not remedy a fault with that service.
Start with the router in a central, elevated position where practical; Ofcom notes that Wi-Fi signals weaken as they pass through objects. Put an extender between the router and the weak room where it can still receive a usable signal. Mesh nodes likewise need positions that can connect to one another, not just positions beside the dead zones.
Ethernet is worth considering for a fixed calling desk if you can route a cable safely, because the device no longer relies on its local Wi-Fi link. Ofcom recommends a direct Ethernet connection to the router when checking broadband speed. For cables between mesh units, confirm backhaul support on the exact system first.
Not necessarily. A replacement may address a problem with the current router, but Ofcom says walls and other objects weaken Wi-Fi, and no router can outperform the incoming broadband service. If several distant rooms remain weak after sensible router placement, consider whether mesh nodes or a practical wired route better address those locations.
