Start by comparing the connection near the router with the one in your work room: new Wi-Fi equipment cannot increase the broadband speed arriving at your home. If thick walls weaken the connection in the work room, Ethernet to your computer or to a nearby Wi-Fi point is the stronger option where cabling is practical; otherwise, mesh nodes can bring Wi-Fi closer if they can still connect reliably to one another. Replace the main router only after checking your provider’s connection requirements, or consider a provider’s compatible Wi-Fi add-on if you prefer to retain its equipment.
The useful change depends on whether the weak connection is confined to the work room and whether you can run a cable to it.
If calls or work applications struggle away from the router, compare the connection in both places before buying coverage equipment. Ofcom recommends trying Ethernet directly to the router when a more reliable connection is needed.
A cable can connect a work computer directly or feed a Wi-Fi point nearer the desk. Ofcom recommends a wired connection over Wi-Fi for speed and reliability; TP-Link says wired links between its Deco nodes are more stable than wireless links between them.
Replacing provider equipment calls for a check of the installed broadband connection and the provider’s settings. Plusnet publishes requirements for compatible customer-owned routers, while Virgin Media says modem-mode availability depends on the Hub model.
Locate the connection problem first, then choose between a cable, additional Wi-Fi points and a compatible change to the main router.
Choose when: A cable can reach the work computer or a Wi-Fi point near it, avoiding a wireless link through the walls.
Allow for: Cable routing and, for some access points, power-over-Ethernet equipment and mounting.
Choose when: Several rooms need nearer Wi-Fi points and each node can be placed within reach of a usable signal.
Bear in mind: Solid walls can still weaken the wireless connection between nodes, so placement matters.
Choose when: The existing router itself needs replacing and the new one can use your provider’s connection method and settings.
Bear in mind: A different router will not increase incoming broadband speed or necessarily reach through several solid walls.
Choose when: Your provider offers a compatible extension for your account and you want to keep its hub in place.
Check: Equipment restrictions and which parts of the home any coverage commitment includes. BT says its Wi-Fi Discs work only with the new Smart Hub 2.
| Priority | What to check | Your needs |
|---|---|---|
| Work-room reliability | Compare a wired or close-to-router test with the connection at the desk. Check whether Ethernet can reach the computer or a nearby Wi-Fi point; Ofcom advises a wired connection for greater reliability. | I need calls and work applications to stay connected at my desk, not just beside the router. |
| Coverage and node placement | Check where each mesh node can receive a usable connection. Walls, floors and interference affect range, according to TP-Link; a node placed beyond an already weak link cannot avoid that obstacle. | The signal needs to reach rooms separated by solid walls. I can try node positions between the router and work room rather than assuming a coverage-area figure will apply to my layout. |
| Broadband compatibility | Identify the provider, connection type and required router settings before replacing the main unit. Openreach describes an Ethernet port on its FTTP ONT; Plusnet publishes settings for compatible customer-owned routers, while Virgin Media limits modem mode by Hub model. | If I replace the provider router, the new equipment must connect to my particular service, not merely support a newer Wi-Fi standard. |
| Installation and features | For a wired Wi-Fi point, check the cable path, Ethernet ports and power method. If retaining the main router, check access-point mode and its feature restrictions: TP-Link says several Deco router-management features are unavailable in that mode. | I can plan a cable run if it avoids a weak wireless link, but I need to know which equipment and router functions the arrangement requires. |
| Provider equipment | Check eligibility, hub compatibility and the area covered by any provider commitment. BT says its Complete Wi-Fi Discs require the new Smart Hub 2. | I would rather keep a provider-managed setup if its add-on works with my hub and covers the room where I work. |
A Wi-Fi upgrade cannot raise the broadband speed delivered to the home. Ofcom notes that line conditions and simultaneous household use can also affect the connection.
Compare results near the router and in the work room at different times. If the connection is poor near the router too, raise that result with your provider before treating the problem solely as Wi-Fi coverage.
A wireless node still needs a connection to the rest of the mesh. TP-Link says building materials, floors and interference affect range, so a distant node may remain behind the same obstacle.
Try a position between the router and work room where the node has a usable link, or connect nodes by Ethernet where practical.
A difficult layout may call for another node or a cable run.
Connection requirements differ. Plusnet specifies settings for compatible customer-owned routers, and Virgin Media says modem mode is unavailable on Hub 5x.
Before buying, confirm your service type, hub model, required connection settings and any digital-voice or support implications with your provider.
TP-Link says Deco access-point mode leaves several router-management features unavailable. Ubiquiti specifies a Gigabit Ethernet and power-over-Ethernet connection for the U6+ access point.
Check which router functions you use, where the Ethernet cable will run and how the access point will receive power.
These examples illustrate different setup approaches; check the particular model and your broadband connection before choosing.
A consumer mesh range for placing Wi-Fi points around the home, with setup options that vary by model.
The cited eero 6 bundle is an app-led Wi-Fi 6 mesh option for placing multiple units around a home.
The U6+ is a ceiling-mounted Wi-Fi 6 access point for a location that can be reached by Ethernet.
A provider equipment option for eligible BT customers who want to extend Wi-Fi while retaining a compatible BT hub.
These multi-unit mesh systems are options for bringing Wi-Fi points closer to several rooms. They do not replace the decision to use Ethernet where a cable can reach the work area; check node placement and broadband compatibility for your home.

Three mesh units let you try Wi-Fi point locations nearer rooms separated by walls. Check the broadband connection requirements and, if a wired link between units is part of your plan, confirm Ethernet-backhaul support for this variant.
Not necessarily: replacing the router will not increase incoming broadband speed or remove the effect of walls between it and the desk. Ofcom describes mesh as a way to place Wi-Fi points around the home and recommends Ethernet for a more reliable direct connection; consider those routes if the problem is confined to the work room.
Compare the connection near the router with the connection in the work room, preferably at different times. A good nearby result and weak work-room result points towards in-home coverage; if the nearby connection is poor too, investigate the broadband service and household demand. Ofcom advises testing over several days and at varying times.
It depends on the provider, service and equipment. Plusnet publishes settings for compatible customer-owned routers, while Openreach describes an Ethernet handoff at its FTTP ONT; neither means every router works with every provider. Confirm authentication, connection settings, digital-voice implications and support arrangements for your own service before buying.
Virgin Media says modem mode lets a compatible Hub act as a cable modem for your own Wi-Fi kit, but says the mode is not currently available on Hub 5x. Check the exact Hub model and which Hub functions change before choosing a separate router.
Keep the provider router and use access-point mode when it needs to remain responsible for the broadband connection or other provider functions, provided the mesh system supports that arrangement. TP-Link says Deco access-point mode leaves the main router handling IP addresses, but makes some Deco app features unavailable. Router mode needs a separate compatibility check for your service.
