Bluetooth issue

Hello I am having a very strange issue with my bluetooth. I am running Ubuntu 14.04 on my M3800.

My Bluetooth stopped showing up in my top bar. I checked the bluetooth settings and it says "No Bluetooth Adapter Found" I ran lshw and lspci and did not see any mention of bluetooth. Hcitools -dev shows nothing but "sudo /etc/init.d/bluetooth status" returns "* bluetooth is running".

Dell replaced my wifi/bluetooth card but bluetooth still does not show up.

I have attached the output of lshw, lspci and lsusb to this post.

Thank you.

Try running this:

sudo apt-get install bluez bluez-alsa bluez-audio bluez-btsco bluez-compat bluez-cups \
  bluez-dbg bluez-gstreamer bluez-pcmcia-support bluez-tools bluez-utils python-bluez \
  bluewho indicator-bluetooth libbluetooth-dev libgnome-bluetooth11 libbluetooth3 \
  python-gobject python-dbus

If that fails, you might try downloading the drivers from Microsoft, explained here

The drivers are here but make sure they installed the Intel Dual Band Wireless AC7260, if not post back which one they replaced with.

I have the bluetooth driver downloaded but it comes in an .exe and I don't know how to install it. I could not find any cab or inf files.

I found that page and downloaded the firmware but I do not see anywhere to download the driver. Asides from that the wifi is working so I assume the I have the driver and it is working.

Cheers.

The drivers are in the kernel but the firmware isn't, which is why I'd download the driver for Windows and extract the CAB file then locate the HEX firmware and convert to HCD, and place in /lib/firmware/

check your dmesg log

dmesg | grep -i blue

If missing firmware, run

sudo apt-get install linux-firmware

If it says none to install, then I'm out of ideas.

There are no cab files in the .exe. there are exe, dll, msi, xml and cat. but not cab.

The dell utility shows 

iwlwifi version: 3.0 srcversion: 10E433C430158BEFB778CA1 vermagic: 3.16.0-67-generic SMP mod_unload modversions  

as the driver.

I ran dmesg and nothing showed up for bluetooth also no missing firmware. 

Thank you for your effort.

Do you have bluetooth enabled on your BIOS?

There was no option to enable or disable it. Under miscellaneous devices is external usb which is enabled and usb debugging which is disabled.
