System and method for preventing unauthorized programming of wireless network access devices
First Claim
1. 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 said key code from the device and generating, in accord with a known method, an access code based thereon; and
,comparing said access code to said access enabling code and, if equal, enabling access to the device, otherwise denying access to the device.

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.

8. In a wireless network access device, access to which is controlled by a control program retained in a memory in the device, a system for preventing unauthorized access to the device comprising:
-
means for storing in the memory of the device, data representing a key code and an access enabling code; means, external from the wireless network access device, for reading said key code from the device and generating, in accord with a known method, an access code based thereon; and
,means for comparing said access code to said access enabling code and, if equal, enabling access to the device, otherwise denying access to the device. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A wireless network access device comprising:
-
a control program, retained in the device, controlling access to the device; memory means, coupled to said control program, for storing data representing a key code and an access enabling code; means, connected to said memory means, for communicating data to and from said memory means; and
,means for receiving an access code, said control program adapted for comparing said access code to said access enabling code and, if equal, enabling access to the device, otherwise denying access to the device. - View Dependent Claims (19, 20, 21, 22, 23, 24)
