Check whether the slowdown happens near the router or mainly in particular rooms before buying equipment: Ofcom notes that Wi-Fi cannot outperform the broadband service coming into the home. Where a cable is practical, consider Ethernet for a fixed device; for wireless coverage, consider mesh across several weak rooms or an extender for one area that still receives a usable signal. Replace a provider router only after checking connection and home-phone requirements, and check property-level broadband options if the service itself appears to be the limit.
If the connection works near the router but weakens upstairs or in an extension, start with placement and the obstacles between the router and that room. Ofcom identifies building materials and interference as factors that can affect home Wi-Fi.
When calls, learning, streaming and gaming happen at the same time, find out whether the broadband service or the wireless link is struggling before choosing more Wi-Fi equipment. Ofcom notes that either can limit the experience.
If a device stays in one place and a cable can be routed safely, Ethernet is worth considering before wireless coverage hardware. Ofcom advises that a direct Ethernet connection should be faster and more reliable than Wi-Fi.
Compare performance near the router and in the rooms that matter, then choose a route for the problem you can identify.
| Priority | What to check | Your needs |
|---|---|---|
| Broadband or Wi-Fi? | Compare the same device near the router and in the problem room. If performance is poor near the router too, check the service with your provider; Ofcom's broadband checker gives property-level predicted availability and speeds, which may differ from what you receive. | I want to know whether a new wireless device would address the slowdown, rather than a limit on the broadband service. |
| Several weak rooms | Try a more central router position, then identify the weak rooms and possible node locations. For mesh, check the exact pack size and how its units will connect; walls and other obstacles can affect the result. | Wi-Fi needs to reach several rooms or floors I use regularly, not just one spot near the router. |
| One weak area | For an extender, find a position that still receives a usable signal from the router. Check responsiveness in the intended room: Ofcom warns that extenders and repeaters can affect speed and responsiveness. | There is one room where I need a stronger connection, while Wi-Fi elsewhere is acceptable. |
| Fixed devices | Check whether an Ethernet cable can reach the device safely and whether suitable ports are available. A cable serves that device; it does not extend Wi-Fi to phones around the home. | For a desk computer, TV or console that stays put, I would rather use a wired connection if routing the cable is practical. |
| Shared use | Note when problems occur and whether they affect devices near the router as well as those farther away. Ofcom identifies both simultaneous use and the in-home wireless link as possible constraints; advertised peak Wi-Fi speed alone will not distinguish them. | Calls and other activities happen at once in my household, so I need to understand which part of the connection is struggling. |
| Router replacement | Confirm your provider's connection method, required settings and support arrangements. If you use a broadband-based home phone service, check how it connects before removing the supplied hub. | I want a different router without interrupting broadband or a provider-linked phone service. |
| Powerline route | If running Ethernet is impractical, check the kit's connections and test it in the intended rooms. Do not assume the home's electrical wiring will perform like a direct Ethernet cable. | A cable cannot easily reach the distant room, and I can assess a powerline kit where it would actually be used. |
Ofcom states that Wi-Fi cannot outperform the underlying broadband service. Mesh or an extender cannot remove a service limit that is already apparent near the router.
Compare near-router and problem-room performance, then check the property's predicted broadband options if the connection is slow in both places.
Walls, router placement and interference can change where a wireless signal remains usable.
Locate the rooms that need help and plan router, mesh-node or extender placement around the actual layout before choosing a pack.
An extender cannot make an unusable incoming wireless link dependable. Ofcom also warns that extenders and repeaters can affect speed and responsiveness.
Position it where the router's signal is still usable, then check the connection in the target room. If several rooms are affected, compare mesh or a wired route.
A replacement can involve provider-specific settings and support arrangements. BT describes Digital Voice as a broadband-based home-phone service, while BT Business advises its customers to retain their supplied Hub for fault diagnosis; those arrangements should not be assumed for every provider.
Ask your provider what the replacement must support, how any home phone connects and whether the supplied router needs to remain available.
Allow time to configure and troubleshoot the new setup before relying on it for calls or work.
TP-Link's Deco range is relevant when comparing whole-home mesh configurations, including different Wi-Fi generations.
NETGEAR's Orbi range provides mesh systems to consider alongside its Nighthawk router range.
eero is another mesh range to examine once multi-room wireless coverage is the identified need.
These options cover mesh systems for several weak rooms, an extender for one limited weak area and a powerline kit to consider when routing Ethernet is impractical. Choose the type of connection before comparing the individual products.

A three-unit mesh option to consider when wireless coverage is weak in several rooms. Check where the units can be placed and whether the system works with your existing broadband equipment; coverage in your home will depend on those conditions.

This three-pack is another mesh option for weak coverage across multiple rooms. Confirm the pack configuration, connection to your broadband equipment and workable node positions before choosing it.

Consider this three-pack when several areas need wireless coverage. Its title specifies dual-band BE3600 and 2.5 Gbps Ethernet; check the precise port arrangement, broadband-equipment compatibility and locations for the units rather than treating those figures as a room-coverage guarantee.

This extender fits a targeted weak area if it can be placed where the existing router's signal is still usable. Check speed and responsiveness in the intended room before relying on that connection for calls or gaming.

Consider a powerline kit if the target room is difficult to reach with Ethernet cable. Test the connection on the home's electrical installation in the rooms where you will use it; do not assume it will behave like a direct cable run.
Compare performance near the router with the problem room. If it is poor in both places, investigate the broadband service and check property-level predicted options; if it drops mainly farther from the router, examine placement, obstacles and in-home connection options. Ofcom cautions that Wi-Fi cannot outperform the broadband service.
For one weak area, an extender is an option if it can receive a usable router signal. Mesh is worth considering when weak coverage affects several rooms or floors and you can place multiple units appropriately. Ofcom warns that extenders and repeaters can affect speed and responsiveness.
Start with the main router in a central, elevated position where practical, then plan other units around the rooms that need service. Ofcom identifies building materials, placement and interference as factors affecting Wi-Fi; check the signal at each proposed location rather than assuming it will pass through every wall.
Confirm your provider's connection requirements, settings and support arrangements, including how any broadband-based home phone connects. Keep the supplied router available for fault diagnosis: BT Business, for example, advises its customers to reconnect their Hub when it needs to investigate a fault.
Check that the seller clearly identifies the product and can provide its compliance information. The Office for Product Safety and Standards explains that the Radio Equipment Regulations 2017 govern radio equipment placed on the Great Britain market, including requirements concerning safety, electromagnetic compatibility and protection of the radio spectrum.
