I have a 2018 suburban and have a family member who is sensitive to WiFi, it makes her sick. I have disabled WiFi on the app, on the car and put in a zero SSID number. It is still transmitting radiation as if it were on. Where on the car is the transmitter or where is the Onstar panel so it can be disconnected. I’ve been to the dealer and no one seems to know anything (of course they aren’t going to want that disabled). She currently can’t go in my car because of this so I really need to get it taken care of. Thank you for your help!
