Check whether the slowdown happens near the hub as well as in the rooms where Wi-Fi is weak: a better wireless setup cannot overcome an insufficient broadband service. If the service is adequate, mesh is a route to consider for several weak rooms, an extender for one reachable weak spot, and a replacement router when the existing router appears to be the limitation. Before removing provider equipment, confirm compatibility and any linked phone or other services.
If calls, streams or gaming work near the hub but falter in other rooms or on another floor, compare coverage options and where extra equipment could go. Ofcom advises that Wi-Fi performance depends on the broadband service reaching the home.
When several people are online at once, check whether the limit is the incoming service or the local Wi-Fi before paying for new hardware. Ofcom advises checking whether other people are using the connection for data-heavy activities such as streaming or downloading large game files.
If you want to replace your hub or add your own equipment, check the connection arrangement and any provider-linked phone or coverage features first. The right setup depends on the provider and the equipment already in use.
Consider it: if provider support or linked services matter, ask about a compatible hub or provider coverage option.
Trade-off: availability and compatibility depend on the provider, package and installed equipment.
Consider it: if coverage is broadly adequate but the existing router appears to limit nearby use, and the new router’s connection is compatible.
Trade-off: a replacement router may not resolve weak Wi-Fi in distant rooms, and setup or fault support may be harder than with provider equipment.
Consider it: if the broadband service reaches the hub adequately but Wi-Fi is weak in several rooms or across floors.
Trade-off: multiple units need suitable placement; they improve in-home coverage, not the incoming broadband service.
Consider it: for one problem area where an extender can still receive a useful signal, or where a wired connection could feed an access point.
Trade-off: Ofcom warns that boosters can affect speed and responsiveness; mesh coordination depends on documented compatibility.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Coverage across several rooms | Map weak rooms and possible node positions; check whether Ethernet can connect the units. | If Wi-Fi needs to reach several rooms or floors, I want to know where extra units can go. Around 36% of consumers put multi-room coverage first. |
| Several people online at once | Compare performance near the hub and in affected rooms; check the incoming service before choosing hardware. | When calls, streaming and browsing overlap, I want to identify whether the service or local Wi-Fi is the bottleneck. Around 28% of consumers prioritise diagnosing shared-use slowdowns. |
| One weak spot | Check that a wireless extender can receive a usable signal; if Ethernet reaches the area, confirm access-point mode. | If only one room needs better Wi-Fi, I want to compare a well-placed extender with a wired-fed access point. Around 18% of consumers put one weak area first. |
| Provider compatibility | Identify the hub, connection and any home-phone service; check the provider’s instructions for that exact setup. | If I use provider-linked equipment or a home phone, I want an upgrade that preserves the connection and services I rely on. Around 18% of consumers prioritise provider compatibility. |
Mesh and extenders cannot increase the speed of the incoming broadband service. Ofcom notes that Wi-Fi cannot outperform that service.
Compare performance near the hub with results in weak rooms, using a wired comparison where practical, and check for a provider fault before buying.
Hub functions and modem-mode support vary. BT’s Digital Voice instructions, for example, connect a corded phone to a port on the hub.
Identify the exact hub, connection and phone arrangement, then check the provider’s instructions before replacing or reconfiguring equipment.
Ofcom warns that boosters can affect speed and responsiveness, while an extender’s placement depends on the signal it receives.
Map the affected rooms first. Compare one suitably placed extender for a single area with a multi-node system for several rooms.
Compatibility can depend on the exact models and operating mode. TP-Link conditions RE705X EasyMesh coordination on a compatible router, while MERCUSYS says its Halo H and S series cannot work together.
Check the exact model, supported system and intended operating mode before adding equipment.
The Deco mesh line and RE-series extenders offer different routes to compare, depending on whether weak Wi-Fi affects several rooms or one area.
ZenWiFi XD5 is a mesh option to compare if you can position multiple units, including in a home with suitable wall Ethernet ports.
The Halo H80X three-pack is a Wi-Fi 6 mesh option to consider for a multi-room setup.
For BT customers, compare the supplied hub and provider coverage equipment before removing a hub used for other services.
These options cover mesh systems, routers and an extender for households choosing between multi-room coverage, a single weak spot or a router change.

A three-unit mesh system for a home considering Wi-Fi in several rooms.
The product description lists dual-band Wi-Fi 7 and a 2.5Gbps LAN port on each satellite. Check documentation for the intended Great Britain or Northern Ireland market before buying.

A router option for a household checking both modem-based broadband use and a SIM-based connection.
The product description lists dual-band Wi-Fi 6, a 2.5Gbps WAN/LAN port and Gigabit LAN ports. Its 5G/4G connection requires a suitable SIM and network service. Check documentation for the intended Great Britain or Northern Ireland market before buying.

For one weak area, place the extender where it can still receive a usable signal from the existing router.
The product description lists range-extender and access-point modes, a 1Gbps LAN port and EasyMesh compatibility with a compatible router. Check documentation for the intended Great Britain or Northern Ireland market before buying.

A mesh router to consider if you may add compatible equipment for wider home coverage.
The product description lists tri-band Wi-Fi 7, MLO and mesh expansion with compatible AQUILA PRO AI routers or extenders. Check documentation for the intended Great Britain or Northern Ireland market before buying.
No. Ofcom says home Wi-Fi cannot outperform the broadband service. Compare performance near the hub and, where practical, on a suitable wired connection before choosing hardware; contact your provider if you suspect a service fault.
It depends on the hub model. Virgin Media documents modem mode for the Hub 3, 4 and 5 and certain older Super Hubs, but says it is not currently available for Hub 5x. Check your installed model and linked services before changing the setup.
If you use a corded handset with BT Digital Voice, BT’s setup instructions connect it to the phone port on the hub. Confirm your arrangement with BT before removing its hub; this does not establish that a third-party router provides the same phone connection.
Place the main router centrally where the connection allows, and put an extender where it can still receive the existing signal. Ofcom advises keeping the router off the floor and away from signal-blocking objects or interfering electrical equipment where possible; check the affected room after setup.
It can make setup and fault support more difficult: Ofcom warns that a provider may be unable to help with problems resulting from a third-party router. Check whether a provider upgrade is available and review the terms that apply to your account before changing equipment.
