Pods connected buts devices do not work!

All of my pods and gateway are online. My devices, ex. Apple TV, amazon fire stick, cell phones, that are connected to the WiFi network show great connection but do not work. Will not stream any type of video, and cell phones will not sent messages or connect to internet, regardless everything is connected, working and supposedly with great signal. I have restarted the gateway, restarted all devices connected with WiFi , and disconnected and reconnected the WiFi network to each device that is connected and NOTHING is working, what do I do??
