Wi-Fi in the garden or backyard: how to get it there
Outside there are no walls in the way, so why does the Wi-Fi die at the back door? Because the thickest wall in the house is the one you just walked through.
In this guide
The first warm evening of the year, laptop on the garden table, and the Wi-Fi is gone. It seems odd, since there's nothing between you and the sky. The trouble is what's between you and the router.
Why the garden is harder than it looks
- Exterior walls are the thickest walls in the house. Brick, block or stone, plus insulation, plus render. Some insulation boards have a foil layer that works like a mirror for radio waves.
- Modern windows block more than you'd expect. Energy-efficient double and triple glazing often has an invisible metallic coating to keep heat in. It also keeps Wi-Fi in.
- Distance adds up fast. The router is usually in the middle or at the front of the house. The garden table is the far end, plus the width of the patio.
- Nothing reflects the signal back. Indoors, walls and ceilings bounce some signal around corners. Outdoors, whatever doesn't reach you directly is simply lost.
Fixes, from free to dedicated
1. Open the path. A router on the garden side of the house, near a door or an older window, can make the patio usable without spending anything. A glass door that's open for the evening helps too.
2. A node by the garden door. A mesh node or extender just inside a door or window facing the garden, placed where it still receives the router well, usually covers the patio. See where to put a mesh node.
3. An outdoor access point. For regular use of a larger garden, an access point rated for outdoor use, mounted on the outside wall and wired back to the router, is the clean solution. Wiring once is better than juggling extenders every summer.
4. Use 2.4 GHz for the far end. At the bottom of the garden, a slower but steadier 2.4 GHz connection often beats a 5 GHz one that keeps dropping. See 2.4 GHz vs 5 GHz by room.
What to avoid
- Indoor devices outside. Extenders and mesh nodes aren't built for rain, frost or direct sun. Keep them indoors near a window, or buy outdoor-rated hardware.
- An extender in the garden shed trying to repeat a signal that's already weak by the time it gets there.
- Boosting the router's power. A louder router reaches your phone, but your phone still has to reach the router. Outdoors, that return trip is often the one that fails.
Check the spots you actually use
You don't need coverage of every blade of grass. You need the table, the bench, maybe the hammock. With WiFi Heatmap, run the connection test at each of those spots, and map the rooms along the garden side of the house to see where the signal leaves the building strongest. That's where the node, or the door you leave open, belongs.
