Abstract
In a wireless network access device, access to which is controlled by a control program retained in a memory in the device, a method of preventing unauthorized access to the device comprising the steps of: storing in the memory of the device, data representing a key code and an access enabling code; reading the key code from the device and generating, in accord with a known method, an access code based thereon; and, comparing the access code with the access enabling code and, if equal, enabling access to the device, otherwise denying access to the device. The invention also includes a system and a wireless network access device both of which prevent unauthorized access for reprogramming purposes.
