    Why were you not satisfied with the solution?

    You could try opening a file you know exists on the internet, that way if you can't open it, you know you aren't connected?

    There are 2 things that need to work in order to have a "valid" internet connection:

    Your side must be connected, and the server side must be connected. Opening up a webpage or a socket connection is the best way to verify that both sides work. In particular, you should try opening a socket/webpage that you want to connect to in the first place.
