The moment the sun comes out, the garden becomes a second living room — and everyone expects the Wi-Fi to come with them. Zoom calls from the patio table, kids streaming on the trampoline, a Sonos speaker on the deck. The problem: most home routers were designed to cover a three-bedroom house, not the hundred-foot garden behind it.
If you have tried moving your router closer to the back door, or standing at a specific angle to get one bar on the patio, this is for you.
Why indoor Wi-Fi does not reach the garden
It comes down to walls and physics. Your router broadcasts a radio signal. Every wall, window and floor it passes through soaks up energy. A double-glazed patio door can halve the signal. A brick wall halves it again. By the time the signal reaches the far end of the garden, there is nothing useful left.
Thick stone walls — common in older Thames Valley properties — are even worse. We regularly see houses in Marlow and Henley where the Wi-Fi dies two metres past the back door.
"Range extender" repeaters make the signal bar look better on your phone, but they halve your actual throughput. You get a full-looking bar that loads pages like dial-up.
The proper fix: an outdoor access point
The right solution is a dedicated outdoor access point, wired back to your network with an Ethernet cable. No repeating, no signal loss — the access point gets a clean, full-speed connection from the router and broadcasts its own strong signal right where you need it.
The access point we fit most often for gardens is the UniFi U6 Mesh — a weatherproof unit rated for outdoor use that mounts under a soffit, on a wall, or on a post. It handles rain, frost and the full range of British weather without complaint.
One access point, mounted at the back of the house, will typically cover a 30-metre radius with usable signal. For longer gardens — or L-shaped ones with outbuildings — we add a second unit partway down.
What about the cable?
The Ethernet cable is the bit people worry about, but it is usually the simplest part. Most of the time we can run an outdoor-rated Cat6 cable along the soffit or through an existing conduit, with no visible cabling. If there is already a route for a security camera cable, we will share it.
For new-build properties — and there are plenty going up around Maidenhead and Beaconsfield right now — we strongly recommend running a couple of outdoor Ethernet drops during the build, while the walls are open. Retrofitting later costs five times as much.
No Ethernet route at all? There is a fallback: a point-to-point wireless bridge. Two small units with line of sight between them, creating an invisible Ethernet cable through the air. We use these for garden offices and detached garages where digging a trench is not practical. They add latency, but less than you would think — around 1–2 ms.
Garden offices and outbuildings
Post-Covid, garden offices are everywhere. And most of them are running off a consumer Wi-Fi extender plugged in by an extension lead. This works until it does not — which is usually during an important video call.
A garden office needs its own access point, wired back to the house. If you are doing video calls, you want at least 50 Mbps of reliable upload — which means a real backhaul connection, not a repeated signal bouncing off the kitchen window.
We will also put the garden office on its own network (VLAN), so your work traffic is separate from the kids iPads and the smart-home devices. This is straightforward on UniFi gear and means your employer VPN is not fighting the Ring doorbell for bandwidth.
What about mesh systems?
Mesh kits like Eero, Google Nest and Deco are designed for indoor use. Some people put a satellite node by the back door and hope for the best. Sometimes it works — in a small courtyard garden, that might be enough.
For anything bigger, mesh falls short outdoors for two reasons:
- No weatherproofing. Consumer mesh nodes are indoor devices. Leave one on the patio and the first proper rainstorm kills it.
- Wireless backhaul halves throughput. Each hop from node to node halves the available bandwidth. A wired outdoor access point does not have this problem.
We are not anti-mesh — we install it where it makes sense. But for gardens, a purpose-built outdoor AP on a wired backhaul outperforms mesh every time.
5 GHz vs 2.4 GHz outdoors
Quick version: 2.4 GHz travels further but is slower. 5 GHz is faster but does not reach as far. Outdoors, with fewer walls in the way, 5 GHz actually performs well at range — better than most people expect.
A good outdoor access point broadcasts both bands simultaneously and steers your device to whichever is best at that moment. You do not need to think about it, and you should not have to pick a network manually.
Typical costs
A single outdoor access point installation — including the unit, outdoor-rated cabling, mounting and configuration — runs £350–£550 depending on cable-run length and mounting complexity. That includes integrating it with your existing network so it roams seamlessly: you walk from the kitchen to the garden and your phone switches without dropping.
A garden office setup with its own access point, VLAN and proper backhaul is typically £500–£800. If we need a wireless bridge to get across the garden, add around £200 for the pair.

Is it worth it?
If you use your garden for more than occasional browsing — video calls, streaming, smart speakers, security cameras covering the driveway — then yes, decisively. An outdoor access point is a one-time cost that makes the garden properly usable, every day, for years.
