Check whether the weak connection starts with your broadband service or with Wi-Fi inside the home before buying hardware: Ofcom notes that Wi-Fi cannot outperform the broadband connection. For one weak area, consider a targeted extender; for several rooms, consider mesh. A router upgrade may suit an ageing or unreliable main router, while Ethernet, a wired access point or a suitable powerline route may make more sense for a difficult-to-reach room.
If Wi-Fi works near the router but falters in a bedroom, loft or extension, identify how many areas are affected. Router placement may help; one remaining weak area points towards an extender, while several weak rooms make mesh worth considering.
When calls, streaming, gaming and study happen together, check whether the broadband connection or the home Wi-Fi is slowing down. A router upgrade may be relevant if the current unit is the limitation; Ethernet is also worth considering for fixed devices.
If you plan to keep a provider connection and add mesh, a router or an access point, identify the exact hub and connection type first. Check how the new kit connects and which device will retain routing duties.
Start with the location and timing of the problem, then choose hardware for the area you need to reach and the equipment it must work with.
| Priority | What to check | Your needs |
|---|---|---|
| Broadband or Wi-Fi | Compare the connection near the router and, where practical, over Ethernet. Check whether slowdowns vary by time or coincide with several people using the connection; Ofcom notes that Wi-Fi cannot exceed the broadband service. | If every room is slow, I want to investigate the connection before buying coverage equipment. |
| Coverage area | Mark the weak rooms and consider walls, distance and router placement. Which? describes extenders as targeted additions and mesh as a broader whole-home approach. | One room needs a usable signal, or several rooms and floors need attention; the extent of the problem changes what I should buy. |
| Simultaneous use | Check what happens when multiple devices are active, rather than relying on an advertised maximum speed. Consider an Ethernet connection for a fixed, demanding device; Ofcom recommends a direct wired connection for more dependable speeds. | Calls or games should remain practical while others in the household are online. |
| Hub compatibility | Identify the exact provider hub and connection type. Check the chosen kit’s Ethernet connection and router or access-point mode, including which device will provide network controls. | I want to extend coverage without losing a provider-hub function my household uses. |
| Installation route | Check whether a cable can reach the room or whether the intended mains sockets suit a powerline kit. For wireless equipment, plan locations that still receive a usable connection. | A hard-to-reach room may call for a wired or powerline route rather than another wireless node. |
| Setup and support | Check the exact model’s setup instructions, operating modes and manufacturer security-update information before purchase. | I need equipment I can configure alongside my existing hub and maintain afterwards. |
Ofcom notes that home Wi-Fi cannot outperform the broadband service. If the connection is also slow near the router or over Ethernet, extra Wi-Fi coverage may leave the underlying problem unchanged.
Compare results at different times and check for a provider fault before treating a mesh system, extender or router as the solution.
Which? distinguishes an extender for a targeted area from mesh for broader home coverage. The number and position of weak rooms matter more than the product category alone.
Map the affected rooms and choose a targeted or multi-node approach accordingly.
The connection method and available modes depend on the exact hub and added equipment. Changing modes can also change which device supplies network-management functions.
Check the provider’s instructions and the new product’s setup guide, then decide which device will act as the router.
Walls and the positions of routers or nodes affect the route a wireless signal must take. A powerline kit also needs suitable mains-socket placement.
Try a more central router position, plan where nodes or cables would go, and check the powerline kit’s socket instructions before ordering.
Deco is relevant when considering mesh alongside an existing router.
Orbi is a mesh range with add-on satellites for compatible existing Orbi systems.
AiMesh-capable equipment is relevant if an existing router will remain at the front of the network.
These options cover a targeted extender, multi-unit mesh systems, a powerline kit and a router-upgrade route. Match the type of connection and the area you need to reach before comparing individual models.

Consider this range extender for one contained weak area. Plan a location that still receives the existing router’s signal, and check compatibility with your router if you intend to use EasyMesh roaming.

This three-unit mesh option is relevant when weak areas span several rooms. Its title specifies dual-band BE3600 and 2.5Gbps Ethernet; check how the router and satellites would be placed and connected to your existing modem or gateway.

Consider a powerline route for a distant room where running Ethernet cable is impractical. Check the intended electrical route and whether both units can use suitable wall sockets; do not assume the named AV1300 rating describes throughput in your home.

This three-pack is a mesh option for several weak rooms rather than a single targeted spot. Check node positions and whether router or access-point mode will work with your provider hub and the network controls you need.

This is a router option for someone considering a change to the main network device, not a multi-unit coverage kit. Check compatibility with your existing broadband connection; using its 5G function also calls for a suitable SIM and local mobile service.
Check whether the connection is also slow near the router or over Ethernet before buying coverage equipment. Ofcom notes that Wi-Fi cannot outperform the broadband service; if a wired connection is slow too, investigate the service as well as the home network.
It can when the chosen system supports a suitable connection and operating mode. TP-Link says Deco can work with an existing router in router or access-point mode; check the Ethernet connection for the main unit and which device will handle routing with your exact hub.
Virgin Media describes modem mode as a way to connect your own Wi-Fi kit to its Hub. Check the instructions for your exact Hub model, whether that mode is available and which Hub features would change before altering the setup.
Ethernet is worth considering when a cable can practically reach the device. Ofcom advises connecting a computer directly to the router by Ethernet for better broadband speeds than using Wi-Fi.
Check the intended mains-socket locations and the kit’s installation instructions. Virgin Media’s booster guidance, for example, calls for direct wall sockets rather than extension leads, power strips or surge protectors; if running Ethernet is practical, compare that route too.
