I got this email from the manager of my dorm: Is there really a way for them to detect if I am using a wireless router in my dorm room? I am using an Airport Express and it is convenient because it allows me to plug my printer into the USB so my printer does not take up space on my desk. And I have a Playstation 3 in the common room with NetFlix. So do you think I should unplug it? Or are they bluffing?
