The network comes first: reliable Wi-Fi in modern builds and thick-walled period houses

Lighting, music, cameras, heating and the family's phones all lean on one thing: the network. If it falters, everything built on top of it feels unreliable. That is why we treat reliable Wi-Fi as the foundation of every project, whether the house is a new build with steel and concrete or a Georgian terrace with walls half a metre thick.

Why reliable Wi-Fi is the foundation of the smart home

Most home systems now talk over the network. Control processors, keypads, cameras, streaming sources and even some lighting interfaces all depend on it. As a result, a weak network shows up as a laggy app, a dropped camera feed or music that stutters in the kitchen. Clients rarely blame the router; they blame the whole system. Getting reliable Wi-Fi right first protects everything else on our list of services.

The problem with a single router

A router in the hall cupboard was designed for a flat, not a five-storey house. Signal weakens with distance and with every wall, floor and mirror it passes through. Mesh extenders can help a little; however, they usually rely on wireless links back to the router, so speed drops with each hop. In larger homes this approach simply cannot deliver reliable Wi-Fi in every room.

Designing for thick-walled period houses

Period properties bring their own challenges. Solid brick, stone and lath and plaster absorb signal far more than modern stud walls. Basements, often converted into cinemas or gyms, sit below ground with little chance of a signal reaching them. Consequently, we plan for an access point in almost every principal room, each with a cable run back to the rack.

Listed buildings add another layer. Cable routes need care, and visible equipment must be kept to a minimum. Fortunately, modern ceiling access points are small and neutral, and they can often sit in cornices, joinery or service voids. Where a listed fabric is involved, early agreement with the conservation officer saves time later.

Modern builds are not automatically easier

New builds might seem simpler, yet they can be just as tricky. Steel frames, foil-backed insulation, underfloor heating and low-emissivity glazing all block or reflect wireless signal. Large open-plan spaces also bring many devices into one area. Therefore, the same principle applies: wire the access points, plan their positions on the drawings and let the network be designed rather than guessed. Reliable Wi-Fi in a modern build is planned, never assumed.

What a reliable Wi-Fi design includes

A properly designed network usually includes:

• a central rack with a managed switch, firewall and backup power
• wired ceiling or wall access points, positioned by survey rather than guesswork
• a wired connection to every fixed device that can take one, such as TVs and processors
• separate networks for guests, home systems and the family's own devices
• remote monitoring, so problems are spotted before anyone notices

We often specify Ubiquiti equipment for its management tools and reliability, although the right platform depends on the house. Standards from the Wi-Fi Alliance also move on quickly, so we choose hardware with headroom for the next few years.

Planning reliable Wi-Fi with the design team

Reliable Wi-Fi starts on the drawings. Access point positions should be agreed with the lighting designer and interior designer, so they sit neatly among downlights and joinery. Cable routes back to the rack need to be in the services plan before first fix. Our process builds these conversations into design and specification.

Keeping it reliable after handover

Reliable Wi-Fi is not a one-off. Devices change, families grow and software needs updating. With remote monitoring in place, we can see issues and often fix them without a visit. For more on that side of things, read more in our insights, or learn about ECHO Integration.
