Start by checking Wi-Fi near the router and trying a more central, elevated position; new equipment cannot make your broadband service itself faster. If several rooms remain weak, consider mesh nodes where they can maintain a usable link, while a router upgrade is more relevant when the existing router is the problem across the home. Before replacing provider equipment, confirm compatibility, support and any features you would lose.
If Wi-Fi works near the router but drops away in other rooms or on another floor, you may need to plan where additional coverage points could go. Ofcom notes that signals weaken through objects and that some materials block them more than others.
When the route between the router and the rooms you use crosses substantial barriers, consider possible node positions or an existing Ethernet route rather than relying on an advertised coverage area. Ofcom identifies building materials as a factor in Wi-Fi coverage.
If you prefer to retain provider equipment or support, check whether a provider service works with your exact hub. A retail router or mesh system may need a different connection arrangement and may not retain every hub feature.
Consider it: when you want your provider to remain responsible for setup and support, or your current router may be outdated.
Check: eligibility and hub compatibility; BT says its Complete Wi-Fi discs work only with the new Smart Hub 2.
Consider it: when the router appears to be the weak point across the home, rather than a few distant rooms.
Check: how it connects to your provider’s equipment and who will help troubleshoot it; a single router position may still leave distant rooms weak.
Consider it: when several rooms or floors remain weak and you can place units with a usable connection to one another, or connect them by Ethernet.
Check: node placement and operating mode. TP-Link says some Deco app features are unavailable in Access Point mode.
Consider it: when you already own a compatible mesh system and have identified a remaining weak area with a suitable place for another unit.
Check: the exact system and model. TP-Link documents compatibility within Deco, while provider-supplied nodes can have hub-specific requirements.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Coverage in several rooms | Map weak rooms and floors; check where each proposed mesh unit could maintain a usable link. | If I need Wi-Fi in several rooms, I want to plan coverage points rather than rely on one router’s advertised reach. About 36% of consumers put coverage across several rooms first. |
| Links through walls or floors | Check the layout, barriers and Ethernet options, then confirm the system’s backhaul support and wiring requirements. | For rooms beyond difficult walls or floors, I need a workable connection path, not simply more wireless units. Around 29% of consumers prioritise a reliable link through difficult construction. |
| Whether the router is the bottleneck | Compare performance near the router with the affected rooms; consider whether the issue also occurs during shared use. | If problems occur throughout the home or when several devices are in use, I want to know whether the router is the issue before adding coverage points. Roughly 21% of consumers prioritise router or shared-device performance. |
| Compatibility and support | Note the provider and exact hub model, existing mesh family and features you rely on; check supported connection modes. | If I want to keep provider features or add to equipment I already own, I need a compatible option with a clear support arrangement. About 14% of consumers prioritise provider compatibility or extending an existing mesh system. |
A Wi-Fi issue in distant rooms may relate to placement or building materials, while slow service near the router may have a different cause. New Wi-Fi equipment cannot increase the speed delivered by the broadband service.
Compare the connection near the router with the affected rooms, then try a more central, elevated router position before buying.
Replacing equipment without addressing the cause can leave the coverage problem unresolved.
Compatibility depends on the specific hub or mesh family. A node that does not join your existing network may require a separate setup.
Check the exact hub, mesh family and full model before choosing an additional unit. TP-Link documents compatibility among Deco models; BT says its Complete Wi-Fi discs require the new Smart Hub 2.
Changing a provider hub’s operating mode can affect features you rely on, and supported modes vary by hub.
Check the exact hub and dependent services before changing settings. Virgin Media says modem mode is not currently available for Hub 5x and lists hub functions disabled in that mode.
Provider-managed coverage for eligible customers considering Complete Wi-Fi with a Smart Hub 2.
Provider-managed Pods for compatible Virgin Media Hubs, or a hub retained alongside separate Wi-Fi equipment.
Deco mesh systems for multi-room setups, including configurations that may use Ethernet backhaul or an existing router.
Retail mesh systems, including the eero 6+ for households planning multiple units.
Retail routers such as the RT-AX58U, with a possible expansion route using supported AiMesh equipment.
These Joybuy choices include multi-unit mesh systems for planning coverage points across rooms, alongside routers for households checking an upgrade or future expansion route. Confirm how any router connects to your provider’s equipment before choosing.

A Wi-Fi 7 router to consider if you want a router upgrade with a compatible expansion route.
The listing says additional compatible AQUILA PRO AI routers or extenders are needed to create an expanded mesh network.
Not if the incoming broadband service is the limiting factor. Compare the connection near the router with the affected rooms first; Ofcom says Wi-Fi cannot outperform the broadband service.
Do not assume that any retail router will work with your setup. Confirm the provider’s connection method, exact hub, supported settings and any services that depend on it. Virgin Media, for example, documents modem mode for specified Hubs but not currently for Hub 5x, and lists functions disabled in modem mode.
Choose positions where units can communicate while serving the weak rooms. If Ethernet is practical, check the exact model’s backhaul support and wiring rules; TP-Link documents different Deco wiring arrangements for router and Access Point modes.
Check the mesh family and full model first. TP-Link says Deco models can be combined within a Deco network, while BT says its specified Complete Wi-Fi discs work only with the new Smart Hub 2.
Ask your provider about eligibility and terms before choosing its coverage service, and check whether the retail features you want require payment. eero says some security and network-management features need a separate subscription; Ofcom also cautions that a provider may not help troubleshoot a third-party router.
