How to disable Xfinity hotspot on my modem?
To disable the Xfinity hotspot, use the Xfinity app, going to WiFi > View Wi-Fi equipment > Advanced settings > Xfinity WiFi hotspot network, and toggle it off; alternatively, use the website at customer.xfinity.com/#/settings/security/hotspot, but some hidden Xfinity networks (like for TV boxes) might still broadcast.
