We've run in to a similar issue on our campus. We currently only allow gaming systems on the wired network, so some students have tried bridging the gaming system to their laptop. The bridged connection triggers spanning tree on the AP port which would reboot the AP. The student's laptop would then associate with the next closest AP and it would cause that one to reboot. The student usually realizes that the hack won't work and would quickly delete the bridged connection. For those students who were more persistent, we would black list their laptop and wait for them to call our help desk complaining that they can't get on the wireless network..
