I am a Windows user trying to adapt to Linux. Currently, I am running Ubuntu 16.04.

Recently I changed my wireless card from a Realtek RT3290 with severe connection problems under Ubuntu and Mint for a Qualcomm QCA9565 also known as DELL 1705.

The problem is: I don't have bluetooth with neither card. Previously, with RT3290, the blutooth module coudn't load but I did see something bt related under "rfkill list". Now, I don't see anything at all! This module was installed on a Dell Laptop with Windows and the bluetooth part worked just fine.

Here's some information:

Do you have any suggestions? The strange thing is that I also tried installing Windows 10, but it didn't recognize my bluetooth either.
