If you’re experiencing a WiFi popup on your Android device, there are a few things you can do to try and stop it. First, make sure that your device is up to date with the latest security patches. If that’s not possible or if you don’t have them installed, then try disabling WiFi popups altogether by going to Settings -> Security -> WiFi Popups and unchecking the box next to “Enable.” If that doesn’t work, then you may need to try disabling specific networks or devices in your network. Finally, if all of these measures don’t work or you still experience the popup, then you may need to reach out to Xfinity customer service for assistance.
