I use my A500 in class. We have WiFi, but when you attempt to log on, you get a sign-in page where you enter your name and phone number. Then you have to download this Bradford Dissolvable Agent file and run it. This is some type of virus protection for the schools network. When ever I try to download it, I always get "Download Unsuccessful" As a result, I cant get on the schools network. I am wondering if there is some setting that is stopping me from downloading. Any ideas on how to fix this would be appreciative.
