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

1-25. -25. (canceled)

26. A method for establishing communication between a wireless station and a network, the method comprising:

establishing a plurality of network profiles in a profile database of the wireless station comprising displaying a dialog box to a user, wherein the user manually enters the network profiles into the profile database using the dialog box;

establishing a first link using a network profile of the network profiles;

periodically examining the first link for a need to establish a new second link;

determining that link quality of the first link indicates that the second link is needed; and

establishing the second link comprising;

selecting another network profile of the network profiles without requiring the user to manually select the another network profile; and

reconfiguring parameters automatically in accordance with the another network profile.

27. The method of claim 26 wherein the first link is established with a first access point device.

28. The method of claim 27 wherein the second link is established with a second access point device.

29. The method of claim 26 wherein the establishing the second link further comprises issuing a command to a driver of a wireless card of the wireless station to establish the second link, wherein upon establishing the second link, the second link is an established link and the first link is a previous link.

30. The method of claim 29 further comprising periodically examining the established link for a need to establish a new link, the new link being different from the established link.

31. The method of claim 30 further comprising pausing the periodic examination upon a determination that the link quality is good.

32. The method of claim 31 wherein the periodic examination is paused for three seconds.

33. The method of claim 30 wherein the periodic examination is repeated once every three seconds.

34. The method of claim 30 further comprising determining whether an access point device-used for the established link is a same access point device used for the previous link.

35. The method of claim 34 wherein upon a determination that the access point device used for the established link is not the same access point device used for the previous link, the method further comprising:

determining whether the TCP/IP setting for the access point device used for the established setting is static or dynamic.

36. The method of claim 35 wherein upon a determination that the TCP/IP setting is static, the method further comprising:

releasing a current IP; and

renewing the current IP.

37. The method of claim 35 wherein upon a determination that the TCP/IP setting is dynamic, the method further comprising:

releasing a current IP;

renewing the current IP; and

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

38. The method of claim 26 wherein the user uses the dialog box to associate unique names to access point devices of the network profiles.

39. The method of claim 26 wherein the user uses the dialog box to enable power saving mode.

40. The method of claim 26 wherein the user uses the dialog box to set transfer speeds for communicating with access point devices of the network profiles.

41. An apparatus comprising:

a processor;

a memory comprising program instructions, wherein execution of the program instructions by the processor generates a method comprising;

establishing a plurality of network profiles in a profile database comprising displaying a dialog box to a user, wherein the user manually enters the network profiles into the profile database using the dialog box;

establishing a first link using a network profile of the network profiles;

periodically examining the first link for a need to establish a new second link;

determining that link quality of the first link indicates that the second link is needed; and

establishing the second link comprising;

selecting another network profile of the network profiles without requiring the user to manually select the another network profile; and

reconfiguring parameters automatically in accordance with the another network profile.

42. The apparatus of claim 41 wherein the establishing the second link further comprises issuing a command to a driver of a wireless card to establish the second link, wherein upon establishing the second link, the second link is an established link and the first link is a previous link.

43. The apparatus of claim 42 wherein the method further comprises periodically examining the established link for a need to establish a new link, the new link being different from the established link.

44. The apparatus of claim 43 further comprising pausing the periodic examination for three seconds upon a determination that the link quality is good.

45. A computer program product comprising a tangible computer readable storage medium comprising computer code comprising:

a configuration module for establishing a plurality of network profiles in a profile database comprising displaying a dialog box to a user, wherein the user manually enters the network profiles into the profile database using the dialog box;

the configuration module further for establishing a first link using a network profile of the network profiles;

the configuration module further for periodically examining the first link for a need to establish a new second link;

the configuration module further for determining that link quality of the first link indicates that the second link is needed; and

the configuration module further for establishing the second link comprising;

selecting another network profile of the network profiles without requiring the user to manually select the another network profile; and

reconfiguring parameters automatically in accordance with the another network profile.
