How does Windows know whether it has internet access or if a Wi-Fi connection requires in-browser authentication?
I see "internet connection" or "no internet connection" on the network chooser in windows 7. How does it knows if it has an internet connection at all? What site does it ping? (or access, or lookup.... or ???)
You can also hardcode your DNS servers and then connect to a local router that doesn't have access to verify this. It won't know that you're not actually connected if you have DNS – Steven Mietelski – 2011-01-04T21:16:09.830
