From my personal point of view, internet connection in the classroom will rather do harm to your academic study. Sage experts of DIU all the time think of the benefits for the students. If they consider internet connection in the classrooms would be beneficial for you people, gradually you might be connected to it.
Yet, I repeat, it will rather do harm to your academic study. All the teachers aggregate required example and demonstrate through multimedia, its perfect way of teaching.
Please keep some task to be done outside classes/home/lab. It will keep your concentration alive with sufficient brain storming.
Furthermore, considering importance of internet in the classes, respective teachers shift class to our computer labs. So, you need not to think to be deprived.
