Start by checking the broadband connection and comparing performance near the router with the rooms where problems occur: Wi-Fi cannot outperform the broadband service feeding it, and walls, distance and devices can affect the wireless link, according to Ofcom. If the connection works well near the router but several rooms have weak Wi-Fi, consider placement changes or mesh; a targeted extender may suit one weak area, while Ethernet is worth considering for fixed devices with a practical cable route. Replace a router only if the incoming connection and coverage checks point to a local router bottleneck, and confirm compatibility and provider support first.
Who this guidance is for
Households with several rooms in use
If people stream, make calls or play games in different rooms, check whether the issue is weak Wi-Fi away from the router or a problem with the incoming connection. Ofcom and Which? discuss how distance, walls and shared use can affect home connectivity.
Households using several devices at once
When calls and entertainment compete for a connection, compare performance near the router with performance during busy periods before deciding whether the broadband service or local Wi-Fi equipment needs attention. Ofcom explains that Wi-Fi performance depends on the broadband service as well as the router and home conditions.
Households with stationary devices
If a computer, console or television stays in one place, consider whether a cable route is practical before relying on Wi-Fi for that device. Ofcom recommends Ethernet as a way to connect a computer directly to a router.
What to consider before choosing
Check the broadband connection first
Consider when: The connection is slow throughout the home, including near the router or on a wired device.
Trade-off: A postcode checker can show predicted local availability, but it does not diagnose room-by-room Wi-Fi or guarantee the speed at a particular property, according to Ofcom.
Placement or a replacement router
Consider when: Try a central, raised position first; consider a router change only if coverage is otherwise adequate but connected devices still strain the current setup.
Trade-off: A new router cannot improve an inadequate incoming broadband service, and a third-party model may be harder for your provider to support, according to Ofcom.
Ethernet for fixed devices
Consider when: A stationary computer, console or television can be reached with a cable.
Trade-off: Cable routing and available ports matter, and a wired connection does not increase the speed supplied by the broadband service.
Mesh for several weak areas
Consider when: The incoming connection works adequately near the router but multiple rooms or floors have weak Wi-Fi.
Trade-off: Mesh needs careful node placement and more equipment than a single-room extender; coverage claims do not guarantee results in a particular home.
An extender or wired access point
Consider when: One room is weak and an extender can be placed where the existing router signal is still usable, or Ethernet can reach the room.
Trade-off: Mesh features depend on compatible equipment; TP-Link specifies that the RE705X requires an EasyMesh-compatible router for its EasyMesh feature.

What to check when buying |
Who this matters to |
| Weak Wi-Fi in several rooms |
Compare near-router and affected-room performance; check whether mesh node positions and any wired backhaul are practical. |
If several people need calls, streaming or gaming in different rooms, multi-room coverage may be the priority. Around 33% of consumers put this first. |
| Several devices in use at once |
Compare a wired or near-router connection with busy-period performance; check router and provider compatibility before replacing equipment. |
If calls, streaming or gaming compete when the household is busy, handling concurrent use may matter most. Around 27% of consumers prioritise this. |
| Reliable connection for fixed devices |
Check Ethernet availability, cable routing and the number and speeds of ports needed. |
If a stationary computer, console or television can be connected by cable, avoiding reliance on its Wi-Fi link may come first. Around 20% of consumers prioritise a wired connection. |
| Finding the cause before spending |
Compare performance near and away from the router, include Ethernet if practical, and check for provider faults. |
If you want to know whether equipment is the right fix, compare the connection at the router with the problem rooms before buying. Around 20% of consumers put diagnosis first. |
Buying pitfalls to avoid
-
Choosing faster-labelled Wi-Fi gear before checking the incoming connection
Wi-Fi cannot outperform the broadband service feeding it, so replacing equipment may not address a slow connection that is also poor near the router.
Compare a wired or near-router test with results in the affected rooms before choosing hardware.
-
Putting an extender where the existing signal is already unusable
An extender needs a usable connection to the router; an access point connected by Ethernet takes a different route to the room.
Plan a position where the router signal is still usable, or check whether Ethernet and access-point mode are practical.
-
Treating advertised mesh coverage as a guarantee
Walls, layout and placement affect Wi-Fi, so a stated coverage figure is not an in-home measurement.
Map the affected rooms and possible node positions, and check whether wired backhaul is supported if cabling is feasible.
A layout may require additional nodes or cabling, so plan where each unit can go before choosing a system.
-
Replacing a provider router without checking support
Ofcom notes that independently bought routers can be difficult to set up and that a broadband provider may be unable to help with problems involving third-party equipment.
Ask your provider about its router options and confirm the intended setup and compatibility before purchasing.
Relevant brands
TP-Link
TP-Link product lines include mesh, router and extender or access-point options relevant to different home Wi-Fi routes.
- TP-Link United Kingdom specifies optional Ethernet backhaul for Deco X50 and access-point mode for RE705X.
- The RE705X EasyMesh feature requires a compatible router. These are model-specific capabilities, not independently measured coverage results.
NETGEAR
NETGEAR's GS305v3 is a wired-switch option for households adding connections for stationary devices.
- NETGEAR specifies five 10/100/1000 Mbps ports and unmanaged plug-and-play operation for the GS305v3.
- The GS305v3 adds wired ports; it does not provide Wi-Fi coverage.
ASUS
The RT-AX58U is a router option with an AiMesh expansion route.
- ASUS specifies Wi-Fi 6, AiMesh compatibility and four Gigabit LAN ports for the RT-AX58U.
- Wi-Fi 6-specific benefits require compatible client devices, and this model is not itself a multi-node pack.
Amazon eero
Amazon describes the eero 6+ as an app-managed mesh option that can be expanded with compatible eero hardware.
- Amazon describes app-guided setup and expansion with compatible eero hardware.
- Amazon says additional online-security and network-management features require a separate subscription; advertised coverage claims are not guarantees for a particular home.

FAQs
Can a postcode broadband check tell me why Wi-Fi fails in one bedroom?
No. Ofcom's checker reports predicted broadband services and speeds for an area, and actual availability or speeds at a property may differ. Compare performance in the affected room and near the router to investigate in-home Wi-Fi.
Where should I try putting the router before buying mesh?
Try a central position off the floor, away from objects and electrical equipment that may obstruct or interfere with the signal, as Ofcom advises. Then recheck the rooms where Wi-Fi is weak.
Will an extender automatically create one seamless network with my router?
Not necessarily. TP-Link specifies that the RE705X's EasyMesh feature requires an EasyMesh-compatible router, so check the exact models and modes before buying. Its access-point mode uses a wired connection.
Could setup or ongoing features add practical costs?
Yes. Check whether the planned layout needs extra mesh nodes or cabling, and whether desired software features require a subscription. Amazon says additional online-security and network-management features for eero 6+ are available through a separate subscription.
Do product rules apply in the same way in Great Britain and Northern Ireland?
Not in every respect. Office for Product Safety and Standards guidance says the Radio Equipment Regulations 2017 apply across the UK, with some provisions applying differently in Northern Ireland. Check the applicable conformity and supplier information for the product and location.
