Hi, User_13,
Thank you for visiting Sony Community!
You may try my suggestion below to enable the Wireless LAN adapter using the VAIO Smart Network utility:
1. On the desktop, in the system tray, double-click the VAIO Smart Network icon.
2. In the VAIO Smart Network window, click the button next to WLAN.
NOTE: When Wireless LAN is enabled, the indicator button will display a green light.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
Regards,
Vincent
