Thanks for your quick reply and pointing me to link above but sadly this is nothing like the problems I am having as the person in that post has his Bluetooth recognised in device manager which I haven't, I have nothing in device manager to inform me that Bluetooth is recognised however I do have the Network Adaptor listed correctly and is working fine on both bands.
If I can get to see the Bluetooth part recognised my problem I think would be over.
Please tell me something I can do to enable Bluetooth on my Sony Vaio as I stated above the last adaptor QUALCOMM Atheros had both Bluetooth and WiFi on same card and worked flawlessly, but it only had 2.4ghz which is no good where I live as there are 30 or more networks around me and traffic is horrendous hence why I needed 5ghz.
This can be caused by a compatibility issue between the computer and the device. Another option is that the computer may come with a Bluetooth device and can be causing conflicts.
We have received reports from users that running Windows Updates fixed some issues.
My best recommendation is to contact the Computer Manufacture and verify the device compatibility.
