If broadband works well at the router but Wi-Fi struggles in several rooms, consider wired access points or Ethernet-connected mesh where cabling is practical; wireless mesh is an alternative when it is not. For one reachable dead spot, try router placement before an extender. Powerline is worth considering only if the intended sockets share an electrical circuit, as TP-Link specifies.
If broadband works near the router but Wi-Fi fades across floors or behind internal walls, several coverage points may make more sense than an extender for one room. Ofcom notes that brick internal walls can make Wi-Fi harder to distribute.
For a home office or gaming setup, check the connection between the remote Wi-Fi point and the router, not just the signal shown on a device. Where cabling is practical, eero says Ethernet backhaul can improve the speed, stability and latency of its mesh links.
If the existing router serves most rooms adequately, try improving its position first. An extender is another option when it can receive a useful signal between the router and the weak room, as NETGEAR advises.
Identify whether the problem starts with the broadband connection, then choose a coverage route around the rooms affected, the available cabling and the equipment you need to keep.
| Priority | What to check | Your needs |
|---|---|---|
| Broadband or Wi-Fi? | Compare an Ethernet connection at the main router with Wi-Fi in the weak room. Ofcom’s postcode checker gives predicted broadband availability, not the speed guaranteed at your property. | If the connection is poor even beside the router, I want to investigate the service before buying equipment for a distant room. |
| Rooms and obstacles | Map every weak room and note floors, internal walls and the router’s position. Ofcom says signals weaken through objects and that brick internal walls can make coverage harder. | Several rooms need coverage, so I need to plan where additional Wi-Fi points could connect. For one weak room, I would try a better router position or a suitably placed extender. |
| Connection between points | Check whether Ethernet can reach the remote room. Without it, place a wireless mesh node or extender where it still has a useful upstream signal; according to eero, Ethernet backhaul can improve its mesh links. | Video calls or gaming in a distant room matter to me, and I can run a cable. I would consider a wired access point or compatible Ethernet-connected mesh. |
| Electrical wiring | For powerline, confirm that the router-side and target-room sockets are on the same electrical circuit. TP-Link says adapters on different circuits will not communicate. | Running Ethernet is impractical and walls obstruct a wireless link. I would consider powerline only after checking the sockets I intend to use. |
| Provider equipment | Before replacing a hub, check the provider, hub model and any phone, TV or managed-Wi-Fi requirements. Virgin Media says modem mode is unavailable on Hub 5x; BT says its Digital Voice service depends on a powered Hub. | I use services connected to my provider’s hub, so I want to confirm whether new Wi-Fi equipment can work alongside it rather than assuming the hub can be removed. |
A new Wi-Fi point will not resolve a slow connection that is already apparent at the main router.
Compare an Ethernet connection at the router with Wi-Fi in the weak room. If the wired connection is also poor, investigate the service first; Ofcom’s availability checker provides predicted local service options, not an in-home Wi-Fi diagnosis.
An extender or wirelessly connected mesh node still needs a usable connection back to the router. A weak upstream signal can remain the limiting factor.
Start an extender roughly halfway towards the weak room, as NETGEAR advises. Position mesh nodes where they can maintain a useful link, or check Ethernet backhaul if cabling is practical.
TP-Link says powerline adapters on different electrical circuits will not communicate, so the sockets determine whether this route can work.
Check the intended router-side and remote-room sockets before choosing a kit, then test the connection in the room where you will use it.
Internet access alone does not establish that provider phone, TV or managed-Wi-Fi functions will continue unchanged. Virgin Media’s modem-mode options vary by Hub model, while BT says Digital Voice needs a powered Hub.
Confirm requirements for your exact provider, hub and services. If you need to retain the hub, check whether the proposed Wi-Fi system can be used alongside it in a suitable operating mode.
These product lines illustrate different coverage routes; a brand’s inclusion does not determine which setup will work in a particular home.
Offers mesh, extender and powerline equipment, with UK guidance that relates the choice to home layout and construction.
A mesh-focused range that includes Wi-Fi 6, Wi-Fi 6E and Wi-Fi 7 models, according to eero’s product listing.
Offers Orbi mesh systems as well as range extenders for more localised coverage needs.
Offers powerline Wi-Fi kits, including two- and three-adapter configurations in its Magic 2 WiFi 6 next range.
These options cover multi-room mesh systems and one powerline Wi-Fi kit. Choose the connection method and placement that fit your home before comparing individual models.

A three-unit mesh option to consider when several rooms need coverage. Plan node positions around walls and floors, and check its operating modes against your existing hub if you need to keep provider services.
No image available
A powerline route to consider for a remote room when a wireless link is difficult and Ethernet cannot readily be run. TP-Link says the intended adapters must be on the same electrical circuit; do not treat the AV1300 designation as a promised speed in your home.
No image available
A three-unit mesh option for coverage across several rooms. The product name specifies 2.5 Gbps Ethernet; check the port arrangement and backhaul options for your intended wired devices or node connections, as well as compatibility with your provider hub.

A three-unit mesh option for a multi-room coverage plan. If you intend to connect nodes or devices by Ethernet, confirm the ports and supported backhaul setup for this exact pack; also check how it would work with your provider hub.

A three-unit mesh option when weak Wi-Fi affects more than one room. For a planned wired setup, check the number and arrangement of Ethernet ports and whether this model supports your intended backhaul connection; confirm provider-hub compatibility separately.
Compare an Ethernet connection at the main router with Wi-Fi in the weak room. If the wired connection is also poor, investigate the service before buying coverage equipment. Ofcom’s postcode checker shows predicted availability and speeds, which can differ from those at an individual property.
It can help if the router is at the edge of the home or obstructed, so try a more central position where the connection allows. Ofcom notes that signals weaken through objects and that brick internal walls make Wi-Fi harder to distribute; moving one router may not cover every floor or distant room.
Consider mesh when several rooms or floors need additional coverage; consider an extender when one area needs help and there is a suitable midpoint with a useful router signal. NETGEAR notes that an extender relays the existing signal rather than improving the router’s own capabilities.
Not necessarily. TP-Link says the adapters need to be on the same electrical circuit and will not communicate across different circuits. Check the sockets you intend to use and test the connection in the destination room.
That depends on the provider, hub model and services you use. Virgin Media says modem mode supports connecting your own Wi-Fi equipment on certain Hubs but is unavailable on Hub 5x; BT says its Digital Voice service needs a powered Hub. Check your exact setup before removing equipment or changing modes. On Openreach FTTP, Openreach says its optical network terminal must remain installed and connect to the router’s WAN port by Cat5e or Cat6 cable.
