Check whether the slow connection starts with the broadband service or with Wi-Fi inside the home: better Wi-Fi cannot make the incoming service faster. Try router placement before buying equipment; consider mesh for persistent weak-signal rooms, Ethernet for demanding fixed devices, or a compatible replacement router if the existing one is the problem. Investigate a service upgrade when the incoming connection is limiting simultaneous use.
Work, study or streaming is interrupted in rooms far from the router or separated by floors and signal-blocking materials, even when the connection is usable near the router. Ofcom advises checking the in-home Wi-Fi connection separately from the broadband service.
A desk-based computer, games console or other fixed device needs a dependable connection. Ofcom recommends a direct Ethernet connection where practical; wired mesh backhaul or a tested powerline arrangement may also be worth considering for another room.
A replacement router or mesh kit has to fit the broadband connection and existing equipment. An Openreach Full Fibre installation, for example, uses an optical network terminal connected to the router by Ethernet; router, access-point and bridge modes affect how additional equipment is set up.
Compare the connection near the router with the rooms where problems occur, then decide whether coverage, a fixed device or the incoming service needs attention. Before choosing new routing equipment, check how it connects to the broadband provider’s existing setup.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage across rooms | Try a more central router position, then identify persistent weak rooms and signal barriers. For mesh, check where a physically connected main unit and other nodes could go. | If the connection works near the router but fails where I work or study, reaching those rooms is my priority. Around 33% of consumers put whole-home coverage first. |
| Fixed-device reliability | Check for a practical Ethernet route or wired mesh backhaul. Test powerline on the intended electrical circuit before depending on it. | For calls or gaming at a fixed desk, I would rather use a dependable connection than rely on a weak wireless link. Roughly 27% of consumers prioritise fixed-device reliability. |
| Compatibility and setup | Identify the provider, connection type and modem, router or optical network terminal. Check the required WAN connection and router, access-point or bridge mode. | If I plan to keep provider equipment, I need the new system to work alongside it without losing features I use. About 20% of consumers make compatible setup their main concern. |
| Incoming broadband capacity | Compare performance near the router at different times and check address-level service predictions with Ofcom before considering an upgrade. | When several of us are online and the connection is slow even near the router, improving room coverage alone will not answer my need. Approximately 20% of consumers focus primarily on the incoming service. |
Ofcom notes that Wi-Fi cannot outperform the broadband service feeding it. Mesh may extend coverage without resolving slow service at the router.
Compare performance close to the router and in problem rooms at different times. Check with the provider about faults, and use Ofcom’s address checker before treating a service upgrade as the answer.
The connection may involve a modem or optical network terminal, provider-specific settings or a choice between routing and access-point modes. eero also recommends a bridge-mode arrangement when it operates alongside another router.
Identify the existing equipment and required connection settings before buying. Keep provider equipment in place until the new arrangement works and you understand the provider’s support requirements.
Ofcom identifies distance, building materials and router position as factors in Wi-Fi performance. A coverage figure cannot establish where nodes will work in a particular home.
Map the weak rooms and likely barriers, then plan positions for the main unit and any additional nodes before choosing a kit.
TP-Link’s setup guidance says its powerline adapters must be on the same electrical circuit to communicate. A connection in one pair of rooms does not establish that another pair of sockets will work.
Test the intended sockets before relying on powerline for a critical fixed device; consider an Ethernet route if predictable performance is essential.
Deco mesh systems can operate as a router or in access-point mode alongside existing routing equipment, depending on the setup.
eero mesh equipment can take the routing role or work with an existing router, subject to the provider’s connection requirements.
NETGEAR positions its Orbi 870 and 970 mesh lines for homes considering multi-gig wired connections and higher-end Wi-Fi 7 equipment.
These products cover multi-unit mesh systems for rooms with persistent Wi-Fi gaps and a powerline kit to consider where running Ethernet is difficult. Check the broadband connection and the proposed node positions or electrical circuit before choosing between them.

Consider this three-unit mesh system if weak Wi-Fi persists in several rooms after improving router placement.
The product name specifies Wi-Fi 7 and BE3600. TP-Link says a Deco main unit needs a physical connection to the modem, router or internet connection; check how that would work with your provider’s equipment.

This is another three-unit mesh option to assess for rooms beyond a single router’s usable wireless range.
The product name specifies dual-band BE3600 WiFi 7 and 2.5 Gbps Ethernet. Check the required connection to your existing broadband equipment and where the units can be placed.

Assess this three-unit mesh system if several rooms need wireless coverage and you have suitable positions for the nodes.
Its product name specifies tri-band Wi-Fi 7 and BE9300. Confirm the required connection to your provider’s equipment and do not treat an advertised wireless class as a speed achievable throughout your home.

Consider this three-unit mesh system for persistent weak-signal rooms where sensible node placement is possible.
The product name specifies WiFi 7. Check how its main unit will connect to your modem or router and whether the proposed positions address the rooms that need coverage.

Consider powerline for a room where running Ethernet is impractical, provided the intended sockets work together.
The product name identifies an AV1300 Gigabit powerline Wi-Fi extender kit. TP-Link says its powerline adapters must be on the same electrical circuit to communicate, so test the intended sockets before relying on this route.
Compare the connection near the router with the rooms where it struggles, including when several people are online. Ofcom says Wi-Fi cannot outperform the broadband service: problems limited to distant rooms point towards in-home coverage, while slow performance near the router warrants checking the service. Ofcom’s address checker gives availability and speed predictions, not a guarantee of results in your home.
Yes, some systems can operate alongside an existing router, but their connection and operating mode matter. TP-Link says a Deco main unit must be physically connected and Deco can use access-point mode; eero recommends putting one routing device into bridge mode when it is used with another router. Check the setup required by your provider and the features retained in that mode.
Identify the optical network terminal and confirm the replacement equipment’s Ethernet WAN connection and provider settings. Openreach says its Full Fibre terminal connects to the router by Ethernet. Leave Openreach-owned terminal equipment in place and establish how the new router or mesh system will connect to it.
Powerline is worth testing when an Ethernet run is impractical, but it is not a dependable substitute without a socket test. TP-Link says its adapters must share an electrical circuit to communicate. Try the intended sockets before relying on the connection for a fixed workstation or entertainment device.
Openreach instructs renters to obtain their landlord’s permission for a Full Fibre installation. For separate internal Ethernet work, check the tenancy agreement and get permission for any proposed changes to the property before arranging the work.
