A Wi-Fi link only worked while it was raining

The Wi-Fi only works when it's rainingPredrag Gruevski / predr.ag, 2024

A home internet connection ran over a point-to-point Wi-Fi bridge. In dry weather it dropped almost every packet, but within minutes of rain starting it worked normally, and about a quarter of an hour after the rain stopped it failed again. The author pings each hop to find where the loss begins, tests the equipment over a wired connection, and checks cables, power supplies and antennas one by one. The explanation for why rain helped is not what anyone would guess first.
