Fayetteville or UoA here in Arkansas had it to where DNAS would not connect through the school internet. They said "this is the main port hackers come in"

so your college might have the same thing going on. Now as for a way around that. You "can" buy your own internet for the room but that is costly and very much so if your by yourself with no roomie. But if you do have a roomie buy the fastest speed you can afford and out do the campus internet any way
