Issue:

I'm running a dual boot installation of Ubuntu 20.04 in a HP SPECTRE 360. It has an Intel Wireless-AC 9462 wireless card that drives both WiFi and Bluetooth included.

The problem is that Bluetooth won't turn on. It says that no Bluetooth device has been found.

Bluetooth not found


Tried solutions:

I've tried to update the iwlwifi driver as specified in here using the most updated version from the Linux firmware repository tree but nothing changes. I however don't know if just replacing the file in the /lib/firmware/ directory is enough or I do have to recompile the driver.

At first I downloaded the driver from Intel's Linux Wireless support website and it comes with a README file that includes some installation instructions on it in which mentions that some kernel configurations have to be made since it uses the kernel's firmware_class infrastructure. I've tried to follow those instructions but I have not been able to find much documentation on how to access the locations it mentions. README file contents:

1. OVERVIEW

1. OVERVIEW

The files iwlwifi-9000-pu-b0-jf-b0-34.ucode provided in this package
must be present on your system in order for the Intel Wireless WiFi Link
AGN driver for Linux (iwlwifi) to operate on your system.

The "-34" in the filename reflects an interface/architecture version number.
It will change only when changes in new uCode releases make the new uCode
incompatible with earlier drivers.

On adapter initialization, and at varying times during the uptime of
the adapter, the microcode is loaded into the memory on the network
adapter.  The microcode provides the low level MAC features including
radio control and high precision timing events (backoff, transmit,
etc.) while also providing varying levels of packet filtering which can
be used to keep the host from having to handle packets that are not of
interest given the current operating mode of the device.

2. INSTALLATION

The iwlwifi driver will look for the file iwlwifi-9000-pu-b0-jf-b0-34.ucode
using the kernel's firmware_class infrastructure.
More information can be found under Documentation/firmware_class in kernel
source. In order to function correctly, you need to have this support enabled
in your kernel.  When you configure the kernel, you can find this option in
the following location:

        Device Drivers ->
                Generic Driver Options ->
                        Userspace firmware loading support


You can determine if your kernel currently has firmware loader support
by looking for the CONFIG_FW_LOADER definition on your kernel's
.config.

In addition to having the firmware_class support in your kernel, you
must also have a working udev and uevent infrastructure configured.
The steps for installing and configuring udev are very
distribution specific.

Once you have the firmware loader in place (or if you aren't sure and
you just want to try things to see if it works), you need to install
the microcode file into the appropriate location.

Where that appropriate location is depends (again) on your system
distribution.  You can typically find this location by looking in the
udev scripts of your distro, the default is /lib/firmware.

Installation of the firmware is simply:

        % cp iwlwifi-9000-pu-b0-jf-b0-34.ucode /lib/firmware

You can now load the driver (see the INSTALL and README.iwlwifi provided with
the iwlwifi package for information on building and using that driver.)

backport-iwlwifi-dkms

I've also noticed that the Software & Updates indicates that it is not using the 3rd party driver and that the device is not working as shown in the following image: Software & Updates screen shot

I tried installing backport-iwlwifi-dkms driver using the package manager Synaptic to solve the issue and it would then show the driver working Software & Updates screen shot after backport-iwlwifi-dkms installation

However I still won't be able to detect the Bluetooth card and the WiFi signal becomes really really slow. won't be able to access any website.


Complementary information:

If I check the service status it says that Bluetooth is running but it won't show on my settings menu.

  • You probably mean Ubuntu 19.10 (ie. the 2019-October release of Ubuntu), but please clarify or correct; there was no 2019-January release of Ubuntu. – guiverc Jan 27 '20 at 4:38
  • That is correct, 19.10 – Marco Castro Jan 27 '20 at 5:23
  • Did bluetooth work on another version or OS? – Jeremy31 Jan 28 '20 at 11:21
