Wi-Fi through stone walls

How do I get good Wi-Fi in a stone cottage or thick stone walls?

The short answer

In a stone cottage or thick stone walls the building is the limit, not the broadband. Very thick external and internal stone Expect the fast band to stop at the first stone wall. We do not quote a single "walls cut the signal by X%" figure, because the loss depends entirely on what the wall is made of.
