I have a PC from a local manufacturer (Avell) that doesn't have an Ubuntu driver for the bluetooth/wireless hardware. I tried everything you can imagine and I've thoroughly described all attempts in the following post (where I still thought it was fixable): Ubuntu 18.04.3 Bluetooth failed to connect: org.bluez.Error.Failed (INTEL® DUAL BAND WIRELESS-AC 9560 + BLUETOOTH)

But after talking to some specialists, I've been told I need to find/write a driver for this hardware in order to have it fully functioning. I've did some research, but I didn't find any.

The hardware is Intel Corporation Wireless-AC 9560, as you can see when I run the following command: lspci -knn | grep Net -A2; lsusb:

00:14.3 Network controller [0280]: Intel Corporation Wireless-AC 9560 [Jefferson Peak] [8086:a370] (rev 10)
    Subsystem: Intel Corporation Device [8086:0034]
    Kernel driver in use: iwlwifi

Bus 001 Device 005: ID 04f2:b65a Chicony Electronics Co., Ltd 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I have high level programming experience and I'm willing to learn myself how to write the driver, but I'm a soft Ubuntu user, never complied a driver or similar. Any help is very much appreciated.

  • You could use ukuu to install a 5.9 kernel and see if that works – Jeremy31 Oct 30 '20 at 10:11
  • Do you really think that would help? I kind of doubt. It's been a year I have this problem and none of the updates nor 20.04 fixed that for me. – bonafernando Oct 30 '20 at 13:50
  • The newer drivers are part of newer kernels and some involve your bluetooth device – Jeremy31 Oct 30 '20 at 15:00
  • Thanks Jeremy31. Is this ukuu safe? This is my working device. Is it reversible? Will my Ubuntu keep being able to be upgraded through software updater UI? – bonafernando Oct 30 '20 at 15:08
  • Jeremy31, the Intel's driver says Kernel 4.14+. So you're assuming that the problem is not on the Driver, but something on the Kernel. – bonafernando Oct 30 '20 at 15:13
  • The wifi and bluetooth drivers are part of the kernel. Intel is constantly making changes to the kernel source code for the iwlwifi driver. The bluetooth is handled by btusb and btintel – Jeremy31 Oct 30 '20 at 17:53

The problem was that one of the antennas of the Intel Corporation Wireless-AC 9560 was disconnected. I've opened the computer and connected the antenna. Now I have a perfect working Bluetooth and an even better Wifi signal.
