The kernel extension for Wi-Fi network devices such as Airport must be removed to ensure that users will not be able to reactivate wireless networking at a later time. System updates will sometimes replace deleted kernel extensions. Administrator users may need to periodically check to ensure that the file remains deleted. Alternately, the wireless card hardware may be removed from the system.
