Households with weak rooms
Broadband reaches the home, but bedrooms, loft rooms or rooms behind internal walls have poor Wi-Fi. Ofcom identifies layout and router location as factors worth checking before choosing equipment to extend coverage.
Who this advice is for
Households using the connection at once
Work calls, study, streaming and gaming overlap. Ofcom advises checking how many people are using the connection, so the household needs to distinguish a broadband-service limit from weak Wi-Fi in particular rooms.
Renters who cannot run fixed cabling
A difficult room needs a better connection without alterations to fixed wiring. Removable mesh units, an extender or a powerline kit may be worth considering, subject to the existing connection, socket locations and equipment suitability.
What to check before buying
Start by locating the bottleneck. Once the broadband service and router position have been checked, let the number of weak rooms and the possibility of using existing electrical wiring guide the equipment choice.
| Concern | What to check | Who this matters to |
|---|---|---|
| Broadband or Wi-Fi bottleneck | Compare affected rooms and devices; try a wired test and check for outages where practical. | If every room slows down during simultaneous use, I want to know whether new Wi-Fi equipment could help at all. Around 33% of consumers put identifying the bottleneck first. |
| Coverage across rooms | Map weak rooms and floor barriers; check how a mesh kit connects to the existing broadband equipment. | When several people need connections in different rooms, I need coverage beyond the space beside the router. Roughly 27% of consumers make multi-room coverage their primary concern. |
| One weak room | Find a position where an extender receives a usable router signal; consider whether reduced responsiveness would matter in that room. | If only my study or bedroom has a dead zone, I would rather address that spot than change the whole network. Around 20% of consumers primarily need a single-room fix. |
| Connection without rewiring | For powerline, check the intended socket locations and whether the adapters can operate on the same electrical circuit. | With thick walls and no option to install permanent Ethernet, I need a route to the difficult room using existing sockets. Roughly 20% of consumers put a connection without rewiring first. |
Common buying mistakes
-
Buying an extender before checking the broadband connection
Ofcom notes that Wi-Fi cannot outperform the incoming broadband service. If wired devices also slow down, or there is an outage, an extender will not address that underlying problem.
Check different times of day and compare a wired connection where practical; speak to the provider about a suspected service problem before buying in-home equipment.
-
Putting an extender where the router signal is already poor
An extender needs a usable signal to repeat. Ofcom also cautions that extenders can affect speed and responsiveness, which matters when the weak room is used for calls or gaming.
Try a more central, elevated router position first. Place an extender within reliable range of the router, or consider mesh if several rooms need coverage.
-
Assuming powerline will behave the same in every property
Powerline depends on the electrical installation. NETGEAR advises using adapters on the same circuit and plugging them directly into wall outlets rather than power strips or surge protectors.
Check where both adapters would go and whether the intended sockets are likely to meet those conditions before choosing a kit.
-
Overlooking the supplied plug on mains-powered equipment
A powerline adapter or mesh unit needs a suitable way to connect to the sockets where it will be used. Government product-safety guidance distinguishes the Great Britain and Northern Ireland markets.
Check the supplied plug, instructions and applicable product marking for the intended location rather than assuming an overseas variant is suitable.
Brands to consider for these network routes
TP-Link
Its Deco range includes mesh systems and hybrid models designed to link units over Wi-Fi and electrical wiring.
- TP-Link describes Deco P9 as combining dual-band Wi-Fi with AV1000 powerline; that specification applies to Deco P9, not every Deco model.
- Deco needs an external internet source and uses app-based configuration. Check the chosen model’s connection to your existing equipment and whether app-led setup suits you.
NETGEAR
Its UK range covers Nighthawk routers, Orbi mesh systems, extenders and powerline equipment.
- The different product families give households routes to assess for a gateway change, wider Wi-Fi coverage or a connection to a difficult room.
- NETGEAR advises that its powerline adapters use the same electrical circuit and direct wall outlets; check those conditions before choosing that route.
eero
An app-led mesh option for households considering placement guidance and network-management controls.
- eero says its service provides placement recommendations, automatic updates and guest Wi-Fi.
- Some advanced controls are associated with eero Plus. Check whether the features you want are included without a subscription and whether app-centred setup suits you.
Joybuy products for specific Wi-Fi needs
These products cover mesh kits for several weak rooms, a powerline kit for a difficult room using existing wiring, and an extender for one limited coverage gap. They will not make an inadequate broadband service faster; check your current gateway connection and the supplied mains equipment before choosing.

TP-Link Deco BE22 BE3600 Wi-Fi 7 Mesh, 3-Pack
Consider this three-unit mesh system when Wi-Fi is weak across several rooms but the incoming broadband connection is adequate. Check how it will connect to your existing internet equipment and whether the supplied power adapters suit the intended location.
No image available
NETGEAR Orbi 370 RBE373 WiFi 7 Mesh, 3-Pack
This three-pack is a mesh option for coverage in several rooms. The product title specifies dual-band BE3600 and 2.5Gbps Ethernet; those figures do not establish the wireless speed you will get at home. Check the connection required by your existing modem or gateway and the supplied power adapters.
No image available
TP-Link Deco BE25 WiFi 7 Mesh, 3-Pack
Consider this three-unit mesh kit if several rooms need Wi-Fi coverage rather than one isolated spot. Confirm how a unit will connect to your existing broadband equipment and check the supplied power adapters for the intended location.

TP-Link TL-WPA8631P KIT AV1300 Powerline Wi-Fi Extender
This powerline kit is an option for reaching a difficult room without installing permanent Ethernet cabling. Check whether the intended wall sockets are on the same circuit, and confirm the supplied plugs suit the location; AV1300 in the name is not a measured speed in your home.
No image available
TP-Link RE220BE BE3600 Wi-Fi 7 Range Extender
Consider this extender for one limited weak area, provided it can sit where the existing router signal is usable. Ofcom cautions that extenders can affect speed and responsiveness, so weigh that trade-off if the room is used for calls or gaming; check the supplied plug too.
Frequently asked questions
Do I need new Wi-Fi equipment or a better broadband connection?
New Wi-Fi equipment is worth considering when the broadband connection is adequate but particular rooms have weak coverage. Ofcom says Wi-Fi cannot outperform the broadband service; if a wired test is also slow or there is an outage, investigate the service with your provider first.
Should a shared home choose mesh or an extender?
Mesh makes more sense when several rooms or floors need coverage, while an extender can address one limited weak area if it receives a usable router signal. Ofcom warns that extenders can affect speed and responsiveness, which is particularly relevant to a heavily used room.
Can I use powerline networking in a rented home?
A powerline kit can use existing wall sockets without installing permanent Ethernet cabling. Its suitability still depends on the electrical layout: NETGEAR advises placing its adapters on the same circuit and plugging them directly into wall outlets rather than a power strip or surge protector.
What should I check before buying a mains-powered network kit?
Check that the supplied plug, instructions and product marking suit the location where you will use the kit. Government guidance distinguishes requirements for Great Britain and Northern Ireland; for equipment intended to plug directly into a BS 1363 socket, confirm the product has the appropriate socket-compatible arrangement.
Will mesh Wi-Fi give me internet without a broadband connection?
No: a mesh system distributes an existing connection rather than creating one. TP-Link says its Deco system needs an external internet source, so check how the model you choose connects to your router, modem or fibre ONT.
