I am in NJ and have a Galaxy S4 and earlier in the evening I noticed when trying to download an app from the Google Play Store the WiFi came on. I thought I had set it to download apps when my WiFi was available and thought nothing else of it. I turned of the Wi-Fi and when trying to access the Internet (google.com) , I am getting an error message that there is a DNS Error, Firewall Blocking Access, or no Internet Connectivity Available. When I tried using Chrome, the Wi-Fi turned back on and I was able to connect. I have 4 bars but am not seeing the 4G LTE, 3G, or 1X logo next to the bars. I can send texts and make calls without a problem, but my Internet service is not working on my phone for at least the past 4 hours. (With the Wi-Fi off I am able to receive Gmail).
Similar type of issue occurred last Friday afternoon, my phone could not connect to the Internet (same Error message), but it did not try to turn on the Wi-Fi. At first I thought it was because there were scattered power outages but after some time it started working again.
