19.10driversiwlwifi
I have a Dell Inspiron laptop with an Intel AC Wireless dual-band 3160 wifi device, My Wifi is working fine but in the Software Center, in the additional driver's section the Ubuntu said This device is not working and only allow to select the Do not use the device.
My Wifi is Working fine and my Bluetooth too. I don't know why this message.
dmesg log
Found the answer in another thread: Bluetooth not working at all after I made some changes to pair with PS3 joystick
Turn off the computer, unplug everything including power, give it a few minutes and then power back up. Bluetooth is back again. (I had tried powering off, and rebooting, but not disconnecting everything)
You can see in the screenshot that it is still acting strange in the Additional Drivers panel, but that Bluetooth devices are successfully connected:

You don't need any backports drivers for this device on Ubuntu 19.10.
Some backports were installed for a previous Ubuntu release that lacked kernel support of this device.
So leave it as is.
You can also remove Dell repository with this backport, not to confuse you in the future.
