First check whether the problem is Wi-Fi coverage: compare the connection near the router and in the weak room, and check for a provider outage. An extender suits one room if it can receive a usable router signal; mesh addresses weak coverage across several rooms, while a powerline Wi-Fi kit is worth considering where wireless obstacles are a problem and both adapters can use the same electrical circuit. Consider replacing the router only after checking its compatibility with your broadband setup.
The number of weak rooms—and whether a device can connect between the router and those rooms—helps narrow the choice.
If broadband works near the router but one room has weak Wi-Fi, check for a usable signal partway towards that room. A wireless extender needs that signal to repeat it; an Ethernet-connected access point is another option where cabling is available.
A mesh system is relevant when coverage needs to reach multiple rooms or floors, particularly if devices move around the home. Check the proposed system’s connection to your existing broadband equipment and the placement of its units.
A powerline Wi-Fi kit can carry the network over household wiring instead of relying on a wireless relay through the obstruction. TP-Link’s UK guidance says its adapters must be on the same electrical circuit, so confirm the intended sockets before choosing this route.
Diagnose the connection first, then choose equipment for the rooms that need coverage and the connection method your home can accommodate.
| Priority | What to check | Your needs |
|---|---|---|
| Find the cause | Compare the connection near the router and in the weak room at different times. Check the provider’s service status and whether heavy household use coincides with the problem; Ofcom also advises restarting relevant equipment. | Wi-Fi is reliable beside the router, but I lose the connection farther away. If it also fails near the router, I need to investigate the service before adding coverage equipment. |
| Reach one room | For a wireless extender, find a position between the router and the weak room that still receives a usable signal. If Ethernet cabling is available, check whether the exact device offers access-point mode. | One bedroom or workspace needs coverage; I do not need to change the network throughout the house. |
| Cover several rooms | Check where mesh units can connect and be placed. Confirm the exact equipment and operating mode if you want a unified network or particular roaming features. | Several rooms have weak Wi-Fi, or I move between them with a connected device. |
| Work around obstacles | For powerline Wi-Fi, confirm that the router-side and destination sockets are on the same electrical circuit. Check the kit’s connection options for any stationary devices in the distant room. | Walls or floors make a wireless relay difficult, but I have suitable sockets at both ends. |
| Change the router | Before replacing supplied equipment, ask the broadband provider about the connection type, modem or ONT arrangement and required settings. Ofcom notes that a separately purchased router can be harder to configure and may limit the provider’s help with faults. | I am considering a new router, but I want to know it will work with my broadband service before removing the existing one. |
Ofcom notes that Wi-Fi cannot outperform the underlying broadband service. An outage or a problem affecting the connection near the router calls for a different fix from a distant-room dead zone.
Compare the connection in both locations, check the provider’s service status and restart relevant equipment before selecting coverage hardware.
A wireless extender repeats the signal it receives. If its position cannot receive a usable signal from the router, placing it in the target room does not address that limitation.
Try a position between the router and the room, using a signal indicator if the model has one. Where no suitable relay position exists, check whether a wired access point or another route fits the home.
TP-Link’s UK powerline guidance requires both adapters to be on the same electrical circuit. The sockets’ location alone does not establish that they meet this condition.
Confirm the circuit arrangement for the router-side and destination sockets before relying on powerline Wi-Fi for that room.
Ofcom says a separately purchased router can be harder to set up and that the broadband provider may not be able to help with problems involving it. It will not resolve a provider outage.
Check the provider’s connection requirements and the exact router’s setup needs. Keep the existing router available until the replacement connection works as intended.
Brand ranges show possible routes, but features and compatibility need checking on the exact model.
TP-Link offers extenders, compatible mesh equipment and powerline Wi-Fi kits in its UK range.
Orbi is NETGEAR’s mesh range for coverage across multiple parts of a home.
eero presents its consumer mesh systems as a whole-home coverage option.
These options include an extender for a targeted weak room, a powerline Wi-Fi kit for a suitable electrical circuit and mesh systems for coverage across several rooms. Match the connection method and setup requirements to your home before choosing a model.

Consider this extender for one weak room if it can be positioned where it still receives a usable signal from the router. If unified-network roaming matters, check compatibility with your exact router rather than assuming the extender will provide it.

This three-pack is a mesh option when several rooms need coverage. Check how it connects to your modem or existing router and where the units can be placed in your home.

This powerline Wi-Fi kit is an option when obstacles make a wireless relay difficult. Confirm that the intended adapter sockets are on the same electrical circuit; results also depend on the home’s wiring.

This three-pack is a mesh option for coverage across several rooms; its name also specifies 2.5Gbps Ethernet. The product information calls for an existing modem or gateway, so check its connection and setup requirements against your broadband equipment.

This three-pack is another mesh route for several weak rooms. Check its operating requirements and compatibility with your router, modem and broadband service before changing the household setup.
Compare the connection near the router with the connection in the weak room. Ofcom also advises checking the provider’s service status, restarting relevant equipment and considering whether heavy household use coincides with the problem; coverage hardware cannot make the incoming broadband service faster.
Place a wireless extender between the router and the weak room, where it can still receive a usable router signal. Avoid placing it solely inside a dead zone, and use a signal indicator if the chosen model provides one.
Do not assume that basic Wi-Fi extension includes mesh roaming. TP-Link’s EasyMesh documentation describes controller and satellite features for compatible devices, so check the support information for your exact router and extender models if a unified network matters.
Consider one when walls or floors make a wireless relay difficult and the intended sockets meet the kit’s circuit requirements. TP-Link’s UK guidance says both powerline adapters must be on the same electrical circuit; check that arrangement before relying on the kit for the distant room.
Confirm the connection type, any modem or ONT requirements and the settings needed for a replacement router with your provider. Ofcom cautions that a separately purchased router can be harder to configure and that the provider may be unable to help with problems involving it.
