Hi,
Sony Vaio VGN-NW20EF/S, have recently upgraded an Atheros card to to Intel Advanced 6235 to add dual band and Bluetooth funcionality. WIFI is working great but Windows 7 64-bit does not see Bluetooth. I have tried using latest Intel Pro/set drivers and also the drivers from Sony website. Under Hidden devices in Device Manager Bluetooth shows as Intel Certino Wireless Bluetooth +High Speed Devices, other than that - no luck. Would appreciate any advice/suggestion. Thanks.
