So I have a Galaxy Tab 4 7.0 and it was working all nice and everything and now it doesn't let me watch YouTube, or do anything that needs a internet connection. I read up on some stuff on this website and I set my time and dates correctly, and it still does not work. I do have a rooted tablet. And it just starting working but then it stopped. It sometimes works and then doesn't. So just to recap it does in fact SAY that I am CONNECTED, but when I try and do something that uses the internet lets say YouTube, it says "Please check your network connection" and this just started happening when I got a new router. - cHiLL Thanks!!
