In Unleashed version 200.1, there is no local upgrade option. You are saying that on Unleashed UI the internet option shows as always "disconnected" but it is connected. This sounds very strange. Are you able to ping "support.ruckuswireless.com" (or other internet sites like google.com, amazon.com etc) from Unleashed UI? If you can't ping these from Unleashed UI itself then there is no internet connection to Master AP (and perhaps to other APs too).
