Bluetooth Peripheral Device software driver not found!

Hi All,

I'm using a Dell Inspiron 1520. I have issues when connecting to my mobile Bluetooth for internet. I own Nokia E72 and I'm able to connect to net using the phone on other laptops.  but where as in Dell I cant. The laptop recognized my phone and the code was entered on the phone as laptop generated. after which my laptop is looking for driver installation software. but unable to find Bluetooth peripheral device software driver.  Even as the phone is connected I'm unable to view it on the blue tooth device screen when trying to connect through 'connect to a network' via bluetooth PAN.. it says unless the driver is installed I cant view my device. Kindly help as I'm not able to find the driver on my laptop nor online.

Thank you

Noel
