Check whether the broadband service is limiting the household before buying more Wi-Fi equipment: Ofcom notes that Wi-Fi cannot outperform the service feeding it. If the connection works near the router but fails across several rooms, assess router placement and then mesh coverage; for a stationary device that can be cabled, Ethernet offers a more reliable connection, while an extender may address one weak area with a speed and responsiveness trade-off.
The connection works near the router but becomes unreliable in bedrooms, upstairs or beyond walls. Ofcom advises considering router placement and, where several rooms remain affected, whether mesh units could extend coverage.
Calls, work and entertainment compete for the connection. These households need to establish whether the difficulty follows people into distant rooms or persists near the router, where the broadband service itself may be the constraint.
A desk computer, television or console can stay in one place, making a cable worth considering when a practical route exists. Ofcom advises a direct Ethernet connection for faster, more reliable performance than Wi-Fi.
Compare performance near the router with performance in the affected rooms before choosing coverage equipment. If the service appears to be the constraint, check availability for the actual property; Ofcom cautions that received speeds and availability can differ from predictions.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage across rooms | Check whether moving the router helps, then consider mesh-unit placement and the coverage stated for the exact pack. | If the upstairs room drops out while the connection near the router works, I need a usable signal beyond one spot. Around 31% of consumers would put coverage first. |
| Simultaneous use | Compare performance near the router or over Ethernet during busy periods; check property-level service availability if the connection itself appears limiting. | When calls struggle while others stream or download, I want to know whether the service or in-home Wi-Fi needs attention. Roughly 31% of consumers would make simultaneous-use diagnosis their primary concern. |
| Fixed-device reliability | Check for an Ethernet port and a practical, safe cable route; add a switch only if more wired ports are needed. | At a permanent desk or television, I can give up wireless convenience for a direct connection. About 23% of consumers would prioritise fixed-device reliability. |
| One weak area | Try router placement before an extender, and consider its possible effect on speed and responsiveness. | For one marginal room, I would rather adjust the existing setup than change coverage throughout the home. Around 15% of consumers would put a local fix first. |
Ofcom notes that Wi-Fi cannot outperform the broadband service. If the connection is poor beside the router as well as elsewhere, additional coverage equipment will not increase the underlying service capability.
Compare the connection near the router and, where practical, over Ethernet before choosing mesh or an extender. If the service appears limiting, check availability for the property.
Ofcom says an extender can increase reach but may reduce speed and responsiveness compared with mesh. Extending one weak area is a different task from covering several rooms with coordinated units.
Test a suitable extender position for a contained weak area; assess mesh if multiple rooms need coverage.
Ofcom notes that larger homes may need more mesh units, but too many boxes can make connection problems worse.
Map the rooms with weak signals and follow the placement guidance for the exact system rather than choosing a unit count from a coverage claim alone.
Ofcom says a third-party router can be trickier to set up and that the broadband provider may not assist with faults involving it.
Ask whether the provider can supply a newer router first. If choosing another model, confirm its connection requirements and the support available for setup and troubleshooting.
The Deco range is relevant when comparing multi-unit Wi-Fi coverage across a home.
The eero mesh range includes the eero 6+ for households comparing pack sizes and coverage arrangements.
The Orbi range covers multi-unit mesh systems, including Wi-Fi 7 models.
Check the broadband service before buying mesh for simultaneous-use problems. Ofcom notes that Wi-Fi cannot outperform that service; if performance remains good near the router but deteriorates in distant rooms, mesh coverage becomes more relevant.
Put the router centrally and off the floor where practical. Ofcom notes that internal brick walls and objects containing water, metal or glass can weaken Wi-Fi, so avoid placing it behind such obstructions.
Use Ethernet for a stationary device when you can run a cable safely and practically. Ofcom advises connecting a computer directly to the router by Ethernet for faster, more reliable performance than Wi-Fi; a switch can add wired ports but will not increase the broadband-service speed.
You may be able to use another router, but confirm compatibility and support arrangements before choosing one. Ofcom notes that third-party routers can be harder to set up and that providers may not help with faults involving them; ask whether your provider can supply a newer router first.
It matters if the service itself may be limiting the household or you are considering a different access technology. Ofcom provides a property-level availability checker, but predicted availability and speeds can differ from what a particular property receives; better in-home Wi-Fi cannot remove a limit in the underlying service.
