Details are sketchy at the moment, but some IT folks at Morrisville State College have tracked down a strong and disruptive signal being emitted from Xbox 360s, which messes with WiFi and possibly other 2.4GHz radios such as Bluetooth headsets. The signal is put out even when the console is turned off, as long as it's plugged in, since the 360 is continually looking for controllers to hook up with. Research is ongoing as to how much interference the 360 is actually causing, but apparently the signal is jumping all over the 2.4GHz band. Of course, 2.4GHz devices have always had a bit trouble with interference, but further research will tell if the 360 is taking things too far.
