My school provides wifi only to professors and faculty using a WPA2 Enterprise login system. Assuming I already have someone else's credentials to log in with, how can I stay secure and avoid the tracking of my usage? I encrypt my traffic using tor, so I'm not afraid of the router sniffing my packets, but what should I do in the realm of randomizing mac and other identifiers? I'm currently using Windows 7 and a wifi adapter with an Atheros AR9271 chipset. Thank you!
