Wifi Open at the in-laws
Even while sitting 3-4 meters away, the signal was so crap, I was loosing connection every 10 minutes or so. So I doubt there is anyone outside the house, and outside the perimeter fence that can even tell there is an AP in use. If they could see the AP, I doubt the return signal would be received by the AP. It's a big old house.
Curious though, lots of the neighbors cats frequent the yard!
