If you use the VAIO Smart Network utility without installing the DLLs/Shared Libraries from Sony, you will hit this. This utility, which is used to control the WWAN device, can only be used if you install the pre-requisite libraries and DLLs. The solution is to ensure that these libraried/DLLs are pre-installed before installing/using the VAIO Smart Network utility.

For the same, (VGN-TZ21VN/X or VGN-TZ class models) you can use the following simple step-by-step procedure:-

  1. Download the Sony Utilities Package by going to the following location - https://support.vaio.sony.co.uk/downloads/info/info.asp?site=voe_en_GB_cons&url=Vaio/Original/TZ21_Utilities.zip&ip=Preinstalled_Utilities.htm.
  2. Accept the License Agreement
  3. Accept the download and save the file to a local folder (about 150 MB)
  4. Extract the ZIP file
  5. Go to Utils Installer 1 SonyUtils DLL folder
  6. Run the setup.exe and follow the on-screen instructions.
  7. After completing the above setup, go to Utils Installer 2 Sony Shared Library folder
  8. Run the setup.exe and follow the on-screen instructions.
  9. After completing the above setup, go to Utils Installer VAIO Control Center folder
  10. Run the setup.exe and follow the on-screen instructions.
  11. The above steps would install the pre-requisites to install the VAIO Smart Network utility.
  12. Now download the VAIO Smart Network Utility:-
    1. Go to https://support.vaio.sony.co.uk/downloads/info/info.asp?site=voe_en_GB_cons&url=VAIO/Updates/EP0000165709.exe&ip=EP0000165709.htm
    2. Accept the License Agreement
    3. Accept the download and save the file to a local folder (about 5 MB)
  13. Now you can use VAIO Smart Network Utility to switch on/off the WWAN device. You can now install the device driver and corresponding connection manager to use the device.

    This does not work with my Sony VGN-Z11VN on Win 7 RC (7100 German). The smart Network Utility does not work correct. If I switch on/off the WWan, the Utility show an error Message "Please check the Wireless switch and try again ...", the Hardware-wireless switch is ON. The other devices (WLan, LAN, BT, Modem) works fine with the build in driver from W7 (but if I switch on/off the WLAN/BT the same Message appears, but the devices works). The WWAN Adapter does not appears in Windows Device Manager. I have check it with various versions of the SNU. I have installed: SonyUtils DLL (Version 7.1.00.15150) Shared Library (Version 5.2.0.11241) Vaio Control Center (Version 3.2.0.09120) Vaio Smart Network Center (Version 2.2.0.12040) I have it checked with all combination of this tools available on the public FTP Server from Sony. Message from Sony: "W7 is not supported yet, no Beta drivers available and this Notebook only works with the preinstallated Version of Vista." helpful suggestions are welcome and sorry about my english. Thanks!

    Thanks for the tip on the old version of Smart Network. WWAn on my Z21WN works perfectly now.
