It seems like the original wireless card has been replaced by the Intel® Centrino® Advanced-N 6230, is this correct?
If that is the case, it may be that this wireless adapter is not compatible with your system and consequently causing the issues with the Bluetooth and the wireless connection. Our first recommendation here is to contact your computer manufacturer as they are the only ones entitled to provide you a list with all the certified and compatible adapters. It is important that you know that Intel does not support integrations, you can find the reasons by accessing this link: Intel® Wi-Fi Products — Regulatory Information Regarding Hardware Installation or Upgrade

Some other users found a solution for the Bluetooth connectivity but, it such solution is not approved by Intel even though it worked for them, that does not mean it will work for you, so please be cautious when using alternative solutions.

This is the original Wi-Fi which I received with my laptop. Its compatible with my system. I already contacted Dell, they replace the card but still the issue not resolved.
The one thing I don't understand if I'm using old driver (from Dell website) which enable the feature "Listen to Music" to work, but if I use newer version from Intel website it doesn't work. I can see the "Listen to Music" option new driver version but whenever I click noting happen why is that. And same goes with extra features of Pro Set Wifi I can't find in newer version of driver whenever I update, it looks only in OEM driver I can get full feature option.
I can't rely on OEM because after some time they stop releasing new driver, so if we using intel product it will better to download from main source.
Please know that the drivers found in our support page are generic and may not be supported by the OEM's system as the wireless adapter suffers modifications done by your computer manufacturer to be fully compatible with their system. In cases like this, we always recommend that the first line of contact should be done with the manufacturer for any updates.
I had a similar problem on windows 10 and Ubuntu with the 6230 with my HP Pavilion Touchsmart and taping off pin 51 as per post #50 Intel Centrino 6235 Bluetooth not detected by windows 7 worked brillinatly.
