I'll chime in here too, with our approach. The majority of our dorms are wireless only, so we can't really push people onto the wired network to avoid things like this. We wouldn't want to do that anyway, however, as the dorms are "home" for our students. The great majority of students are coming to us already accustomed to using wireless at home for everything. Very few even consider plugging into the network, so making sure the wireless is going to support them is really the only way to go.
Obviously QoS might help immediately, but 802.11g is about 7 years old now. 11n plus the airtime fairness mechanisms in all the modern enterprise gear is probably the way to go, whenever you can get there.

Moving 1 TB of data over wireless is really not fair to the other clients. If the usage is necessary, and you have wired Ethernet in place, I would try to have the user move to using the wired connection. If you are only using 802.11g, then a wired connection should be faster and he's eating up less air time. Whether this person is moving that much data for academic purposes or not, it is still interfering with the network utilization of network resources for other users. QoS might help you, though you would probably want to do it network wide, as this person could just move to another area if his/her bandwidth speeds started to drop. If your users are utilizing the wireless network that much, you may want to look at 802.11N.

We are currently using a Bluecoat Packeteer packet shaper to shape traffic at the Internet. The problem I have seen is with user on-line backups, either to a Time Capsule (student moved a terabyte of data in a month) or to (mozy, Backblaze, etc.). We receive complainants that the Internet is slow. I am new to setting up QoS on cisco devices. Is there a way of limiting through QoS on an AP, so that if a student is using all of the radio's bandwidth other users using the same AP have a fair share of bandwidth? I would prefer not to rip and replace our 802.11g APs for 802.11N APs. Any other ideas are welcomed.
