How do I make my WiFi private I have unknown divides connecting to my WiFi
You make it by using the SSID and password. I have found some devices in my home appear to be in xFi Devices list but they are not using the SSID/password. I have an Acurite Weather Station connected by an ethernet connection and it appears in the xFi Devices. I have a Soundbar, a DVD Player, my TV's, all my X1 STB's, etc. The ethernet connections don't need SSID/password. And my MoCA devices don't use it either; they are like the ethernet devices. I use a smartphone app called Net Analyzer that displays all my devices and I compare it to the xFi Devices.
