@Sam, please try the following. Switch to virtual terminal 1 (press Ctrl-Alt-F1) and log in. Run ifconfig and identify the interface that represents your wireless device (e.g. eth1), and then run 'sudo ifconfig eth1 down' (using the interface for your wireless). Please let me know if the system locks up when you do this, and if so whether or not anything is printed on the screen. Thanks!
