If your broadband service is adequate but solid walls leave rooms with weak Wi-Fi, focus on getting a connection to the affected area rather than changing provider. Use a wired access point or Ethernet-backhaul mesh where cable is practical; otherwise, consider wireless mesh with a usable link between nodes, or test powerline where the sockets meet its circuit requirement. Check phone, TV and other provider-managed services before replacing the main router.
Your broadband works near the router, but rooms beyond solid internal walls have weak Wi-Fi. Ofcom notes that brick internal walls can make whole-home coverage difficult; an additional Wi-Fi point beyond the obstruction may matter more than a faster single router.
You have, or could install, a cable to the affected room and want a connection for calls, gaming, streaming or a connected-home device. A wired access point or Ethernet-backhaul mesh avoids relying on a wireless link through the walls between Wi-Fi points.
You need a connection in an isolated room but cannot run Ethernet there. Wireless mesh needs a suitable position for its intermediate node; powerline instead depends on the home’s electrical circuit, which TP-Link says must connect both adapters.
Choose when: Ethernet can reach the weak area, particularly if a wireless link between nodes would cross solid walls.
Allow for: Cable installation and, with some dedicated access points, compatible power equipment.
Choose when: You need Wi-Fi across several rooms and can position nodes where they still connect reliably to one another.
Allow for: The link between nodes remains wireless; placing a node only at the dead spot may leave it with a weak connection.
Choose when: One difficult room needs a connection without new Ethernet cabling and you can test the intended sockets.
Allow for: TP-Link requires the adapters to share an electrical circuit; the connection also depends on the installation.
Choose when: The existing router itself lacks a feature you need and you are prepared to check how your broadband and other services connect.
Allow for: Changing the main router may affect provider-managed features without placing a Wi-Fi point beyond the walls.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage across rooms | Check where additional Wi-Fi points can be placed and whether each has a usable connection back to the network. | If I need Wi-Fi in several rooms beyond solid walls, one router at the far end of the house may not reach them. Around 33% of consumers would put whole-home coverage first. |
| Connection to a busy room | Check Ethernet-backhaul support on the exact mesh model, or the cabling and power requirements of a wired access point. | For calls, streaming or a connected-home hub in a distant room, I would prioritise a dependable link to that room. Wired-room reliability would come first for around 33% of consumers. |
| One room without new cabling | For powerline, confirm the circuit requirement and whether the remote unit needs to provide Wi-Fi or only Ethernet. | If I cannot run a cable to one isolated room, I need an option I can try at the intended sockets. Around 20% of consumers would make that no-new-cable need their main concern. |
| Provider-service compatibility | Before changing the main router, identify the hub model and any connected phone, TV or managed-Wi-Fi services. | If my phone or TV setup depends on the provider hub, I want better coverage without disrupting those services. Keeping provider features working would be the primary concern for around 14% of consumers. |
Ofcom notes that brick internal walls can make whole-home Wi-Fi difficult. A router at the same end of the property still has to send its signal across those barriers.
Plan how a mesh node or access point will connect from beyond the obstruction; use Ethernet for that connection where practical.
Powerline depends on the electrical installation. TP-Link says both adapters must be on the same circuit, while reports in the BT Community describe differing results between homes.
Check the circuit requirement, start by testing the intended wall sockets, and choose a Wi-Fi-capable remote unit only if the room needs wireless coverage.
Virgin Media documents feature changes when eligible Hubs use modem mode. BT says its Digital Voice service depends on powered broadband equipment and stores contacts on the hub; neither condition applies to every provider setup.
Note your provider, hub model, phone and TV arrangements before buying. Keeping the hub as the main router and adding access points or suitable mesh may avoid a change to its routing role.
TP-Link says Deco access-point mode leaves IP address assignment to the existing router, while selected Deco router functions, including port forwarding and address reservation, are unavailable in that mode.
If you use those controls, check where they can be managed and confirm the exact mesh model’s mode-specific features.
Deco mesh, access-point mode and powerline kits are relevant to different ways of extending a home network.
A mesh option for households considering wireless nodes now and a wired connection between suitable nodes later.
A dedicated wired access-point route for a household willing to plan cabling, power and placement.
These mesh systems are options for adding Wi-Fi points across rooms; the powerline kits address a distant room without a new room-to-room Ethernet run. Choose the remote connection type you need, then check node placement or the intended electrical circuit as appropriate.

Consider this three-unit mesh system when several rooms need Wi-Fi points; plan positions where the units can connect reliably.
Check access-point mode if the provider hub must remain your main router, and confirm the supplied power adapters suit your sockets.

Consider this kit when one room needs a Wi-Fi endpoint without a new Ethernet run. The product name identifies it as a Gigabit powerline Wi-Fi extender kit.
TP-Link says powerline adapters must be on the same electrical circuit; test the intended sockets, and check your exact router before relying on OneMesh integration.

This three-unit, dual-band BE3600 system is an option when several rooms need additional Wi-Fi points. Its product name also specifies 2.5 Gbps Ethernet.
Plan a usable connection between unit locations, and confirm Ethernet-backhaul and access-point-mode support for this exact model if either is essential.

Consider this three-pack for Wi-Fi across several rooms, with unit positions chosen around the walls rather than only at the weakest spot.
If you plan to connect particular units by cable or keep the provider hub as the main router, confirm the exact units’ Ethernet connections and access-point-mode features.

Consider this adapter kit for a wired device in a room where running Ethernet is impractical; choose a Wi-Fi-capable endpoint instead if the room also needs wireless coverage.
TP-Link says both powerline adapters must share an electrical circuit. Test the connection at the sockets you intend to use rather than treating AV1300 as the speed you will receive.
Not if the incoming service meets your needs and the problem is coverage inside the home. Ofcom distinguishes broadband service from the Wi-Fi connection around the property and notes that brick internal walls can make coverage harder; assess an additional Wi-Fi point or another in-home connection route before treating this as a provider-switching decision.
A wired access point or mesh nodes connected by Ethernet avoid using Wi-Fi for that hop, provided you can get cable to suitable positions. TP-Link says Ethernet backhaul gives its Deco nodes a faster, more stable connection than wireless backhaul; a wireless mesh remains an option where intermediate nodes can maintain a usable link.
It may, but the building’s age alone cannot tell you how the connection will perform. TP-Link says the adapters must be on the same electrical circuit, so check that prerequisite and test the kit at the sockets and with the devices you intend to use.
Yes, if the chosen mesh system supports a suitable access-point or bridge-style mode. TP-Link says Deco access-point mode leaves IP address assignment to the existing router, but selected Deco router controls are unavailable in that mode; check the features of the exact system before buying.
Check the Hub model and which features change if you enable modem mode. Virgin Media says eligible Hubs can act as a cable modem for your own Wi-Fi equipment, but Hub 5x does not offer modem mode; on Hub 3, 4 and 5, enabling it disables specified Hub features, including Intelligent WiFi and Connect App functions, while its 21CV VoIP telephony continues to work.
