Check whether the broadband service or the Wi‑Fi inside your home is causing the problem before buying equipment: Ofcom notes that Wi‑Fi cannot outperform the broadband connection. Ethernet is worth testing for a fixed device; mesh addresses weak coverage across several rooms, while a single-router upgrade makes more sense when one router can reach the rooms you use. If wired connections also struggle when everyone is online, investigate the broadband service—and check your provider’s requirements before replacing its hub.
Calls, streaming or gaming may work near the router but falter elsewhere. Ofcom identifies router placement and obstacles inside the home as factors to check before deciding whether wider mesh coverage is needed.
If a desktop, console or regular video-call setup can be wired to the router, Ethernet is a useful first test. Ofcom says a wired connection should be faster and more reliable than Wi‑Fi.
Replacing the provider’s router calls for a check of the service connection and required equipment. BT Business, for example, specifies different router requirements depending on the installation and limits helpdesk support for third-party routers.
Compare a wired connection with Wi‑Fi in the troublesome rooms, then decide whether the issue is service capacity, wireless coverage or one device’s connection.
| Priority | What to check | Your needs |
|---|---|---|
| Broadband capacity | Test the connection by Ethernet at different times, including when several people are online. If the service itself is limiting use, compare speeds and availability for your address; Ofcom describes 300 Mbit/s or more as ultrafast and better suited to intensive multi-user use. | Calls, streams or downloads struggle even on a wired device when the household is busy. |
| Room coverage | Try a central, elevated router position and check where the signal weakens. Ofcom identifies mesh as a way to improve signal strength and coverage; a single extender is a narrower option to assess for one weak area. | I can use Wi‑Fi near the router, but need a connection in several rooms beyond it. |
| Fixed devices | Check for an Ethernet port and a practical cable route. Ofcom advises that Ethernet should give a faster, more reliable connection than Wi‑Fi, but wiring one device does not extend wireless coverage elsewhere. | A stationary computer or console needs a steadier connection, and I can run a cable to it. |
| One router or mesh | Consider a single router if one central position reaches the rooms you use; consider multiple mesh units when an adequate broadband service still leaves several weak rooms. Check the equipment’s operating mode before adding it to an existing router. | I need to know whether the problem is the current router or the reach of a single wireless point through my home. |
| ISP compatibility | Confirm the provider’s connection type, modem and WAN requirements, and which device will manage routing. TP-Link documents different Router and Access Point modes for Deco; Virgin Media says modem mode is available on Hub 3, 4 and 5, but not currently on Hub 5x. | Before changing the provider’s hub, I want to keep the connection and the hub functions I rely on. |
Ofcom notes that Wi‑Fi cannot outperform the broadband service. New wireless equipment will not resolve a service-capacity limit affecting wired devices too.
Test by Ethernet at different times, then check service options for your address if the wired connection is also inadequate.
Operating mode affects setup and available functions. TP-Link warns that connecting multiple Deco units directly to an existing router in Router Mode can create a network loop; eero says bridge mode turns off some of its network services.
Decide whether the existing router or mesh system will manage the network, then follow the instructions for the exact model and mode.
The required modem, WAN connection and authentication depend on the service. BT Business identifies PPPoE and different Ethernet WAN or integrated VDSL-modem requirements for different installations, and says its main helpdesk does not support third-party routers.
Check the provider’s requirements for your installation before removing its equipment, and retain the hub if it is needed for fault diagnosis.
Virgin Media says modem mode temporarily disables listed functions, including Intelligent WiFi capabilities and Plume Pod compatibility. It is not currently available on Hub 5x.
Check your exact Hub model and the functions you use before switching modes.
Deco is TP-Link’s mesh line for adding Wi‑Fi coverage alongside an existing router or making a Deco unit the main router.
eero mesh equipment can be configured while an existing router continues to manage the network.
AiMesh is an option for households considering a network of compatible ASUS routers.
Virgin Media Hub settings matter when cable customers want to use their own Wi‑Fi equipment.
These options cover multi-unit mesh systems for households considering wider in-home coverage, plus a standalone router for those considering a single-router upgrade. Check your ISP connection and the required operating mode before choosing equipment.

A three-pack to consider when several rooms need Wi‑Fi coverage. The listed variant is dual-band BE3600 Wi‑Fi 7 with 2.5Gbps Ethernet; confirm how it will connect to your ISP equipment.
No image available
A three-pack for considering Wi‑Fi coverage across multiple rooms. It is listed as a Wi‑Fi 7 mesh system; check which Deco operating mode fits your existing router and ISP connection.
No image available
A three-pack to assess for weak Wi‑Fi in several parts of the home. Check the required Deco operating mode and your ISP connection before replacing or retaining the current router.
No image available
A three-pack to consider for a multi-room mesh setup. The listed variant is tri-band Wi‑Fi 7; if you plan to wire devices to individual units, confirm their ports and the package contents before buying.
No image available
A standalone-router option if one centrally placed unit can reach the rooms you use. It is not a multi-unit mesh pack; confirm its modem, WAN and authentication requirements against your ISP installation.
Compare an Ethernet-connected device with Wi‑Fi in the problem room, including when the household is busy. If the wired connection also struggles, investigate the broadband service and options for your address; if wired performance is sound but distant rooms are weak, check router placement and wireless coverage. This follows Ofcom’s distinction between broadband capacity and in-home Wi‑Fi performance.
Consider mesh when several rooms remain weak after improving router placement and the broadband connection itself is adequate. A single replacement router is a route to assess when one central position reaches the rooms you use; neither choice removes a limit in the broadband service. Ofcom identifies mesh as a way to improve in-home signal strength and coverage.
It can, but choose the operating mode for the exact system. TP-Link documents Router Mode and Access Point Mode for Deco, with Access Point Mode allowing the existing router to retain network functions; eero says bridge mode also keeps the existing router in charge but disables some eero services. Follow the model’s wiring instructions.
Confirm the connection hand-off, authentication and modem requirements for your provider and installation. BT Business says a compatible third-party router may need PPPoE and either Ethernet WAN or an integrated VDSL modem, depending on the setup; its main helpdesk does not support third-party routers.
Virgin Media says modem mode allows your own Wi‑Fi equipment with Hub 3, 4 and 5, but is not currently available on Hub 5x. Check your exact Hub model before changing modes: Virgin Media says modem mode temporarily disables functions including Intelligent WiFi capabilities and Plume Pod compatibility.
