I am having the same problem. I have returned home from university and every time I try to connect to the home Wifi it connects but there is no internet access! It gives me full bars with a little "!" In a yellow triangle. I tried to do what was previously suggested but it did not help, I even tried reverting back to obtaining automatically but it still didnt work. Also do I input those very same values or are there specific values to my modem or pc that I should input?
