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. |

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a method, system and device that will prevent unauthorized reprogramming of the device.
In general, the present invention is embodied in a method used with a wireless network access device, access to which is controlled by a control program retained in a memory in the device, that prevents unauthorized access to the device.
The method includes 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 to the access enabling code and, if equal, enabling access to the device, otherwise denying access to the device.
Likewise, the present invention is also found in a system for use with a wireless network access device, access to which is controlled by a control program retained in a memory in the device, for preventing unauthorized access to the device.
Such a system includes: Circuitry or programming that stores in the memory of the device, data representing a key code and an access enabling code; Circuitry or programming that reads the key code from the device and generates, in accord with a known method, an access code based thereon; Circuitry or programming that compares the access code to the access enabling code and, if equal, enabling access to the device, otherwise denying access to the device.
The present invention is also found in a wireless network access device that includes a control program, retained in the device, controlling access to the device.
A memory device, such as RAM, ROM, EEPROM, or the like, that is coupled to the control program, for storing data representing a key code and an access enabling code.
Data bus circuitry is connected to the memory device for communicating data to and from the memory device.
The device has circuitry, such as an Input/Output data bus interface connector, that is capable of receiving an access code from an external source
