Abstract

A method and apparatus to reconfigure parameters for establishing a link with a new host after a computer is moved to a new location or a new network.

Claims

1. A method to configure parameters after a computer is moved to a new location, comprising the steps of:

periodically examining an established link for a need to establish a new link; and

establishing the new link when examination indicates that the new link is needed, including

automatically selecting a network profile from a plurality of network profiles stored in a profile database setting without requiring the user to manually select the network profile, the network profile containing a plurality of configuration parameters for establishing the new link;

reconfiguring parameters automatically without user input in accordance with the network profile for a current network;

communicating with the network using the selected network profile;

determining if the communication is successful, and if the communication is determined to be unsuccessful, automatically selecting another profile from the plurality of network profiles and establishing the new link with the another network profile.

2. The method of claim 1, wherein the examining step is repeated once every three seconds.

3. The method of claim 1, wherein the establishing step further comprises testing each network profile from the plurality of network profiles until the new link is established.

4. The method of claim 1, wherein the establishing step comprises establishing the new link with an access point including issuing a soft boot command.

5. The method of claim 1, wherein the establishing step comprises establishing the new link with a wireless card.

6. The method of claim 1, wherein the reconfiguring step further comprises:

Searching for a static TCP/IP setting for a current location; and

if found

Releasing a current IP; and

renewing the current IP.

7. The method of claim 1, wherein the establishing step further comprises:

Searching for a dynamic TCP/IP setting for a current location; and

if

found

Releasing a current IP

Renewing the current IP; and

Receiving and returning packets from and to a wireless card driver.

8. The method of claim 1, wherein:

determining if the communication was successful includes determining whether a destination address specified in the currently selected network profile was reachable.

9. The method of claim 1, wherein:

the periodic examination is paused when criteria are satisfied, the criteria being based on a quality of the established link.

10. An apparatus comprising a computer-readable storage medium tangibly embodying program instructions for configuring a computer after the computer is moved to a new location, the program instructions including instructions operable for causing a computer to:

periodically examine an established link for a need to establish a new link; and

establish the new link when examination indicates that the new link is needed, including

automatically selecting a network profile from a plurality of network profiles stored in a profile database without requiring the user to manually select the network profile, the network profile containing a plurality of configuration parameters for establishing the new link;

reconfiguring a current network setting automatically without user input in accordance with the network profile for a current network;

communicating with the network using the selected network profile;

determining if the communication is successful, and if the communication is determined to be unsuccessful, automatically selecting another profile from the plurality of network profiles and establishing a new link with the another network profile.

11. The apparatus of claim 10, wherein the program instructions further comprise instructions to cause the computer to examine the established link once every three seconds.

12. The apparatus of claim 10, wherein the program instructions further comprise instructions to cause the computer to test each network profile from the plurality of network profiles until the new link is established.

13. The apparatus of claim 10, wherein the program instructions further comprise instructions to cause the computer to establish the new link with an access point by issuing a soft boot command.

14. The apparatus of claim 10, wherein the program instructions further comprise instructions to cause the computer to establish the new link with a wireless card.

15. The apparatus of claim 10, wherein the program instruction to cause the computer to reconfigure further comprises instructions to:

search for a static TCP/IP setting for a current location;

release a current IP; and

renew the current IP.

16. The apparatus of claim 10, wherein the program instruction to cause the computer to reconfigure further comprises instructions to:

search for a dynamic TCP/IP setting for a current location;

Release a current IP;

Renew the current IP; and

Receive and return packets from and to a wireless card driver.

17. A computer readable memory which includes a reconfiguration apparatus comprising:

A profile database to store a plurality of network profiles containing reconfiguration parameters for reconfiguring a network environment for a node in a network after the node is relocated to a different location;

A detection process to periodically examine the quality of an established link on a node; and

A selector process, operatively connected to the profile database, to

automatically select, in response to a signal from the detection unit, a next profile stored in the profile database for establishing a suitable network environment for the node without requiring the user to manually select the next profile;

reconfigure parameters automatically without user input in accordance with the network profile for a current network;

communicate with the network using the selected network profile;

determine if the communication is successful, and if the communication is determined to be unsuccessful, automatically select another profile from the plurality of network profiles and establishing a new link with the another network profile.

18. The apparatus of claim 17, wherein the reconfiguration parameters comprise SSID.

19. The apparatus of claim 18, wherein the reconfiguration parameters further comprise associated address and channel.

20. The apparatus of claim 17, wherein the reconfiguration parameters comprise IP address, subnet mask, and gateway.

21. The apparatus of claim 20, wherein the reconfiguration parameters further comprise domain name and DNS address.

22. The apparatus of claim 17, wherein the node communicates with other nodes in the network through access points.

23. The apparatus of claim 17, wherein the node communicates with other nodes in the network in an ad hoc mode.

24. The apparatus of claim 17, wherein the node supports encrypted information.

25. The apparatus of claim 17, wherein the node runs in power saving mode.

26. The apparatus of claim 17, wherein the plurality of network profiles in the profile database is prioritized.

27. A computer readable memory which includes a reconfiguration apparatus comprising:

An auto-sensing process to periodically detect changes in a network environment by checking for a connection, an AP device, and a quality of the connection; and

A user profile management process to

step through automatically a plurality of selected profiles that are stored in a database, each selected profile including parameters to communicate with the network, the user profile management process stepping through the selected profiles without requiring the user to manually select the selected profile;

reconfigure parameters automatically without user input in accordance with the network profile for a current network;

communicate with the network using the selected network profile;

determine if the communication is successful, and if the communication is determined to be unsuccessful, automatically select another profile from the plurality of network profiles and establishing a new link with the another network profile.
