Abstract

As part of a wireless access point configuration process, a computer network is probed and each previously unprogrammed wireless access point on the network is programmed by transmitting wireless network configuration parameters thereto using a software agent residing on a node of the computer network.

Claims

1. A method comprising:

probing a computer network to discover one or more wireless access points by sending messages to known communication ports of the wireless access points, wherein the probing includes periodically testing the computer network by the software agent to determine if the one or more wireless access points are present;

receiving, in response to the messages, access to configuration interfaces of the wireless access points through which the wireless access points can be programmed; and

automatically, without user activity, programming each unprogrammed wireless access point by transmitting wireless network configuration parameters to the unprogrammed wireless access point using a software agent residing on a node of the computer network.

2. The method of claim 1, wherein the probing comprises transmitting additional messages to all local network IP addresses and a returned response is used to identify a kind of each wireless access point involved within the computer network.

3. The method of claim 1, wherein the software agent automatically programs each unprogrammed wireless access point with the wireless network configuration parameters upon detection of the unprogrammed wireless access point on the computer network.

4. A method comprising:

probing a computer network to discover one or more wireless access points by sending messages to known communication ports of the wireless access points;

receiving, in response to the messages, access to configuration interfaces of the wireless access points through which the wireless access points can be programmed; and

automatically programming each unprogrammed wireless access point by transmitting wireless network configuration parameters to the unprogrammed wireless access point using a software agent residing on a node of the computer network, wherein the software agent automatically programs each unprogrammed wireless access point with the wireless network configuration parameters in response to a user authorization but without further user activity.

5. The method of claim 4, wherein the probing comprises transmitting additional messages to all local network IP addresses and a returned response is used to identify a kind of each wireless access point involved within the computer network.

6. The method of claim 4, wherein the software agent automatically programs each unprogrammed wireless access point with the wireless network configuration parameters upon detection of the unprogrammed wireless access point on the computer network.

7. The method of claim 4, wherein the probing includes periodically testing the computer network by the software agent to determine if the one or more wireless access points are present.

8. A computer system comprising:

a processor,

a communication device operatively coupled to the processor and configurable to access other computers via a network; and

a memory operatively coupled to the processor, the memory having stored therein instructions executable by the processor to cause the computer system to;

probe the network to discover one or more wireless access points by sending messages to known communication ports of the wireless access points;

receive, in response to the messages, access to configuration interfaces of the wireless access points through which the wireless access points can be programmed; and

automatically, without user activity, program each unprogrammed wireless access point by transmitting wireless network configuration parameters to the unprogrammed wireless access point using a software agent residing on a node of the computer network; and

periodically test the network to determine if the one or more wireless access points are present.

9. The computer system of claim 8, wherein the memory stores further instructions executable by the processor to cause the computer system to:

transmit additional messages to all local network IP addresses; and

identify, from a response to one or more of the additional messages, a kind of each wireless access point involved within the computer network.

10. The computer system of claim 8, wherein the memory stores further instructions executable by the processor to automatically program each unprogrammed wireless access point with the wireless network configuration parameters upon detection of an unprogrammed wireless access point on the computer network.

11. A computer system comprising:

a processor,

a communication device operatively coupled to the processor and configurable to access other computers via a network; and

a memory operatively coupled to the processor, the memory having stored therein instructions executable by the processor to cause the computer system to;

probe the network to discover one or more wireless access points by sending messages to known communication ports of the wireless access points;

receive, in response to the messages, access to configuration interfaces of the wireless access points through which the wireless access points can be programmed; and

automatically program each unprogrammed wireless access point by transmitting wireless network configuration parameters to the unprogrammed wireless access point using a software agent residing on a node of the computer network in response to a user authorization but without further user activity.

12. The computer system of claim 11, wherein the memory stores further instructions executable by the processor to cause the computer system to:
