Bluetooth on Sony Vaio

I have a Sony Vaio VGN-N220E Laptop. It came pre-installed with Vista Home 32Bit OS. I upgraded to Vista Ultimate 32 Bit OS. Before I upgraded, the bluetooth showed up in device manager, now it does not.
I looked on the Sony support page for Bluettoth drivers, but did not find any. When I look in system Info I find the device (BTHmodem Bluetooth Serial Communications Driver) But it is disabled. Can anyone help me on how to enable this driver?
Thanks

I would suggest that you download the wireless device drivers and the motherboard drivers once more, Bluetooth or not. The Bluetooth Adapter is an option on this model. Unless you purchased this option when you bought the laptop, no Bluetooth capability was there
