I have a key for a neighbourrCOs house, and when they go away I put in some battery-powered Blink cameras covering their three doors, and set the
cameras to Motion Detect. By live-viewing the cameras I can see, e.g if
they have had any post, or if theyrCOve had a power cut (they have a couple
of fridge freezers) or if any breakers have tripped.

So, they went away this weekend, and I installed the cameras as normal.
What was not normal was that they couldnrCOt connect to my Blink network. Slightly puzzled by this as itrCOs never happened before, I substituted some Blink Minicams for the battery ones, but they didnrCOt connect either. I went home and tried moving the Sync Module to different places, but that had no effect.

Puzzled by this, I checked again, and my WiFi network also isnrCOt visible in my neighbourrCOs house. Going back home, my neighbourrCOs WiFi signal isnrCOt visible in my house. Neither is that of my other neighbour, or those
networks of their neighbours. No networks from across the little valley are visible either. Normally I can see all these, but now I canrCOt. What could have happened to reduce everyonerCOs WiFi signal?

The likely answer is forty days of rain. The brick walls of the houses are saturated with water, there has essentially been no sun or drying wind to
take away the moisture.

AI suggests that a 2.5GHz signal suffers 5dB attenuation through a brick
wall, but this might be 15dB for a saturated wall. Given thererCOs two such walls involved, the signal could have been attenuated by an extra 20dB, and this could account for why WiFi signals arenrCOt propagating as normal
outside the walls of the houses. Our external Blink cameras are working as normal, but are close to the house and the signals have only one wet wall
to traverse.

LetrCOs see what happens as the walls dry out.

Do you have inssider home or something similar to check WiFi networks? The legacy version is still available or there is a free Android equivalent.

IrCOm using my iPhone to check the WiFi signal strengths, and I can see the rCyWiFi addressesrCO if I click on the info icons. My computer sees a couple more networks, but they are fading in and out whereas they would normally
be stable signals.
