My tablet shows it is connected to home wifi (Comcast router) and the wifi icon shows data traffic arrows going up and down but any data dependent app (Chrome, Prime video, Netflix, Youtube, Google Play store) will not connect, says there is no connection/no internet. The Chrome error message is: ERR_PROXY_CONNECTION_FAILED. All other devices in the home connect fine. The tablet DOES work fine using different mobile hotspots however from both of my phones. I have rebooted and cleared the browser data and cache and rebooted the router. Any ideas? I have not tried it on a public wifi hotspot or different home network yet but will try that as well.
