Hi! I had a problem solved thanx to some forums on web, so I post this.
In D-Link Wireless Network, after installing SP3 at the boot of PC, there is
an error message about wlanapi.dll. To resolve:
The D-Link AirPlus Utility does not work with Windows XP Service Pack 3.
Upon loading, it displays: "AirGCFG.exe - Entry Point Not Found. The
procedure enry point apsGetInterfaceCount could not be located in the
dynamic link library wlanapi.dll.".
A workaround is to use the pre-SP3 version of wlanapi.dll and place it in
the appropriate directories. Upon loading, this version of the file will be
used instead of the version in the System32 directory.

xcopy %Windir%\$NtServicePackUninstall$\wlanapi.dll
"%ProgramFiles%\D-Link\AirPlus G"
xcopy %Windir%\$NtServicePackUninstall$\wlanapi.dll
"%ProgramFiles%\ANI\ANIWZCS2" --

it worked fine on my PC desktop with Windows XP Pro SP3.....
