My mother claimed to be sensitive to WiFi and feel sick when it’s on. She would often power it off and claim she felt better. My sister lived with her at the time and when I visited, complained she could not use the Internet most of the time. So I hid the station ID but left it on. Told mom the WiFi is off on the router.

Guess what? She stopped complaining about feeling it or feeling sick from it. I don’t know if she eventually found out it was on the whole time (from my sister), but she now uses WiFi herself and has even asked me to help fix it when it was down.

Perhaps some people are just sensitive to SSID broadcasting? ;)
