Is WLANAPI.DLL Essential in Windows Based Wireless Networks?
Wlanapi.dll is a module used in wireless networking. If the wlanapi.dll file is not there in your system, you cannot establish a wireless LAN.
Developed by Microsoft and present in the later versions of Windows XP (x64, x86, SP1, SP2 and SP3) and Vista, wlanapi.dll is essential to compile and configure all Windows-based wireless networks. In Windows XP systems, for the wlanapi.dll file to work, you should have Microsoft Core XML Service 6.0 installed. The Windows Hot Fix KB918997 provides several files including wlanapi.dll for Windows XP systems without existing wireless connectivity configuration options.
The best-known errors with regard to this dynamic link library file are found when using the Wireless Zero Configuration (WZC), also known as Wireless Auto Configuration, or WLAN AutoConfig, a service included with new versions of Microsoft Windows for dynamically selecting a wireless network to connect to based on a user’s preferences and several default settings.
The following errors are quite common:
“The procedure entry point apsxxxxxx could not be located in the dynamic link library wlanapi.dll” (the xxxxxx stands for various applications)
This error happens because there’s a problem with routine in the dll file or the file has corrupted – it can be fixed by ensuring the Wireless Support is not disabled in your network configuration control panel and if necessary, re-installing the wireless application.
“The application cannot start because wlanapi.dll was not found”
When this error comes up, you can download the Windows Hot Fix KB918997 from the Microsoft Downloads Center and apply the updates. The computer must be restarted for the changes to take effect.
“The module Regsvr32 “C:\Windows\System32\wlanapi.dll” was loaded but the entry-point DllRegisterServer was not found. Make sure that Regsvr32 “C:\Windows\System32\wlanapi.dll” is a valid DLL or OCX file and then try again.”
This error only occurs in Windows Vista Ultimate 32. The best way to solve the issues is to use the command prompt, select ‘run as administrator’ and then run the registration command.
