Wi-Fi across three floors
How do I get good Wi-Fi in a three-storey house?
The short answer
In a three-storey house the building is the limit, not the broadband. Concrete or thick timber floors between levels One box per floor, near the stairwell. We do not quote a single "walls cut the signal by X%" figure, because the loss depends entirely on what the wall is made of.
Tell us the walls and floors and we mark where the boxes should go.
| Factor | Why it matters |
|---|---|
| Concrete or thick timber floors between levels | One box per floor, near the stairwell |
| Router usually on the ground floor | Middle floor first — it covers up and down |
| Loft conversion at the far end of the signal | Test the loft room last; that is where the plan usually fails |
