If broadband works well near the router but Wi-Fi falters in particular rooms, try improving router placement before buying equipment. Mesh is worth considering when several rooms remain difficult to reach; a replacement router must suit your broadband setup, while Ethernet can be a more direct choice for a fixed device if a cable run is practical.
Broadband works near the router, but Wi-Fi struggles in rooms separated by walls or other obstructions. Ofcom identifies placement and building materials as factors to check before deciding whether additional Wi-Fi points are needed.
Frequent disconnections make a replacement worth discussing with the broadband provider, particularly if you want a clear route for support before setting up third-party equipment.
If a work computer, console or television remains in one place, a practical Ethernet cable run may address that device’s connection without changing Wi-Fi throughout the home. Ofcom recommends a direct Ethernet connection as an alternative to Wi-Fi for a computer.
Check the connection near the router before treating weak rooms as a Wi-Fi coverage problem. Then assess placement, the number of affected rooms and whether the devices that need help can use a cable.
| Concern | What to check | Who this matters to |
|---|---|---|
| Placement and barriers | Try a more central, elevated position if the router can be moved safely; check whether walls or nearby equipment obstruct the weak room. | When one room loses signal beyond an internal wall, I want to find out whether moving the router helps before adding equipment. Roughly 31% of consumers would put placement and barriers first. |
| Several weak rooms | Identify the affected rooms and possible mesh-node positions; check whether the chosen kit can be expanded if needed. | If Wi-Fi falters across several rooms, I need coverage beyond the reach of one well-placed router. Around 38% of consumers would make multi-room coverage their primary concern. |
| One fixed device | Check for an Ethernet port and a practical, safe cable path to the router or a network node. | For a computer or console that never moves, I would rather connect that device directly than change Wi-Fi for the whole home. Roughly 23% of consumers would prioritise a fixed device’s connection. |
| Retail-router compatibility | Confirm the broadband access type, modem or hub arrangement, and any provider features affected by the proposed setup. | If I want to manage my own router, I need it to work with my service without unexpectedly losing provider features. Around 8% of consumers would put compatibility and control first. |
A new router or mesh system cannot improve the service delivered to the home. Ofcom also notes that simultaneous use can affect the connection available to individual devices.
Compare the connection near the router with the weak room at different times. If performance is poor close to the router too, raise the service problem with your provider before buying coverage equipment.
Wi-Fi capability does not establish whether a router can connect to your broadband equipment. BT says a hub used with its fibre service must be designed for fibre; other access arrangements have their own requirements.
Identify your service type and existing modem, hub or fibre terminal, then check the proposed router’s connection requirements against that setup.
Virgin Media says modem mode on its specified Hub 3, 4 and 5 models temporarily disables certain diagnostics, app, intelligent Wi-Fi and pod functions.
Check your exact Hub model and the functions you use before connecting your own Wi-Fi equipment through modem mode.
Walls, floors and the position of each node still affect whether a mesh system reaches a weak area. A kit’s stated coverage cannot account for every home layout.
Plan where nodes could sit between the main router and affected rooms, then check whether the system supports expansion.
A larger or more obstructed home may need additional nodes, as Ofcom notes in its home Wi-Fi guidance.
Deco is TP-Link’s whole-home mesh range, with different Wi-Fi standards, pack sizes and installation formats.
eero offers app-managed mesh systems, including eero 7 packs.
Orbi is NETGEAR’s range of multi-node mesh systems, including Wi-Fi 7 models.
AiMesh lets buyers build a mesh network using compatible ASUS routers or ZenWiFi systems.
Compare the connection near the router with the connection in an affected room. If it works near the router but falters farther away, investigate placement, barriers and interference; if it is poor close to the router as well, speak to your provider about the service. Ofcom distinguishes in-home Wi-Fi problems from problems with the underlying broadband connection.
Mesh is worth considering when several rooms remain weak after sensible router placement, especially if walls or the layout make one central position impractical. Ofcom describes mesh as a way to improve in-home Wi-Fi coverage, not the performance of the broadband connection itself.
No: the replacement must work with your particular broadband service and equipment arrangement. Check the access type, modem or hub requirements and any provider services you use before buying; Ofcom also cautions that a third-party router can be harder to set up and may limit the help your provider can give with equipment-related faults.
Check that your Hub model supports modem mode and whether you rely on functions it disables. Virgin Media lists temporarily affected diagnostics, intelligent Wi-Fi, pod and app functions for Hub 3, 4 and 5, and says modem mode is not currently available for Hub 5x.
