The Wireless LAN API KB918997 FroWindows XP SP2 77 is a useful hotfix that adds some wireless network management capabilities to Windows XP with SP2 and Windows XP with SP3. However, it is not a complete implementation of the Native Wifi API, and it has some limitations and differences compared to the full Native Wifi API that is available on Windows Vista and later versions of Windows. Therefore, you should consider upgrading your operating system to a newer version that supports the full Native Wifi API if you want to use all the features and functions of wireless network programming.
