I have my own secure WiFi set up on my Comcast home router, and can access WiFi perfectly fine at home from my phone.
I cannot connect to "XFINITY" public hotspots. I can connect to the "xfinitywifi" public hotspots. As I understand it, "XFINITY" hotspots are secure, while "xfinitywifi" hotspots are not secure.
