And how will a loose of internet connection damage your hardware? In my case, my cards are in extra bulding and in winter i have some windows open and many of my cards run with 10 or 20C° and they are running fine. It is better that the cards don´t work if they have no connection. So can you explain how that will protect your hardware?
