A single router in the farmhouse hall was never going to cover a yard, a dairy and three barns. Add thick stone walls, steel-framed sheds and a long drive, and it is no surprise that signal fades the moment you step outside.
The solution is rarely a bigger box. It is a plan. This guide covers how we approach WiFi for farms and other rural premises in the South Hams: survey first, then links between buildings, outdoor access points, proper cabling and power.
Start with a survey
Before buying anything, walk the site with someone who understands how radio signals behave. A survey tells you where the internet comes in, where it needs to go, what is in the way, and how many people and devices will use it.
Write down the places that matter. The farm office, the workshop, the parlour, the holiday cottage, the farm shop till, the cameras on the yard. Not every corner needs coverage. Planning around what you actually use avoids spending money on signal nobody needs.
Stone, concrete, metal cladding and even old lime plaster block WiFi much more than modern plasterboard. Surveying with your own devices, in the places you will use them, shows what really happens rather than what a box promises.
Point-to-point links between buildings
To reach a distant barn or outbuilding, a wireless link is often the answer. Two small outdoor units, one on each building, point at each other and carry the internet across the gap. When there is a clear line of sight, these links can be fast and reliable over a surprisingly long distance.
They are very different from simply turning up the power on a router. A properly aligned link is designed for the job and is not much bothered by what lies between the two ends, as long as nothing solid is in the way.
Trees, hedges that grow in summer, and new buildings can interrupt a link, so it is worth thinking about what may change.
Outdoor access points for yards and fields
If you want signal across a yard, around a parking area or by the farm shop, outdoor access points are built to cope with rain, frost and dust. Mounted on a wall or pole at the right height, they can cover a surprising amount of open space.
Placement matters more than quantity. A few well-sited units are usually better than lots of small ones scattered at random. We plan coverage so devices can move from one to another without dropping a call or a video feed.
Cables beat wireless where you can run them
Wherever it is practical, run a cable. A network cable to a building or room gives a stable, fast connection that does not care about walls. It can also carry power to an access point or a camera, which saves needing a socket in awkward places.
In farm buildings, cables need to be the right type for the job. Outdoor-rated cable, protected runs, and sensible routes away from machinery and livestock will make sure it lasts. Where a trench or duct is needed, it is easier to lay a spare one at the same time.
Our network and WiFi work covers cabling, switches and structured layouts for rural premises, and our WiFi boosting service is a good starting point for homes and smaller sites.
Power and protection
Every piece of network equipment needs power, and farms are not always generous with sockets. Power over Ethernet is useful because it carries power along the same cable. A small battery backup (a UPS) helps the main equipment ride out short power cuts and flickers.
Lightning and surges are a real concern for equipment on outbuildings and poles. Suitable surge protection and proper earthing are part of a good installation, not an optional extra.
It is also worth keeping the network safe. Change default passwords, keep equipment updated and separate guest or visitor devices from the systems you rely on, such as the office computer, the cameras and the card machine.
Make sure the internet itself is up to the job
Even the best WiFi cannot give you a faster connection than the one coming into the property. If your link to the outside world is the weak point, our guide to rural business broadband explains the options.
For farms and rural businesses around the villages inland from Kingsbridge, we regularly help with IT and WiFi in Frogmore and the surrounding area.
Common mistakes on rural sites
Using plug-in extenders on long runs. Each hop can cut speed, and several in a chain make things worse. A cable to a proper access point is far better.
Placing equipment where it is convenient rather than where it works. An access point behind a steel cabinet, or in a loft under a metal roof, will disappoint however good it is.
Mixing up the internet and the WiFi. If the connection into the farm is slow, spreading it further will not speed it up. Fix one, then the other.
Leaving cameras and farm systems on the same network as the office. Keep them separate, so a problem with one does not spill into the other.
Forgetting about weather and wildlife. Outdoor cable that is not protected can be chewed or damaged by machinery, and connectors exposed to rain will fail sooner than you expect.
