I have installed ubuntu 20.04LTS. My laptop is HP probook 645 g4, amd ryzen7. Intel wireless ac3168NGW is used in this laptop to use wifi. After installing Ubuntu, the 'Additional Drivers' in the Software & update, it is showing that intel corporation: Dual Band Wireless-AC3168NGW [stone peak]-this device is not working. and give me an option to contine using a manually installed driver. I have tried 2 common solutions. The wifi comes and suddenly gets disconnected. After getting disconnected, in the wifi section in the system setting, it is showing that the wifi adapter is not found. and the wifi on-off button is gone away. It's really a pain. I have given the 2 solutions below. These do not work perfectly. if anyone gives me a perfect solution,

my-try-1:

wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-3168-ucode-22.361476.0.tgz
tar xvf iwlwifi-3168-ucode-22.361476.0.tgz
cd iwlwifi-3168-ucode-22.361476.0
sudo cp iwlwifi* /lib/firmware
sudo modprobe -v iwlwifi

my-try-2:

sudo apt update
sudo apt install linux-generic-hwe-20.04

and.. I am not using any dual boot. I have installed ubuntu whole my hard drive. "dmesg | grep iwl" result below.

  • Please edit your question to show the result of the terminal command: dmesg | grep iwl Is this a dual boot with Windows? Welcome to Ask Ubuntu.

In your edit, we see many repetitions of:

iwlwifi 0000:02:00.0: Microcode SW error detected.  Restarting 0x2000000. 
iwlwifi 0000:02:00.0: Start IWL Error Log Dump:

There is a very long bug report about firmware crashes and the Intel 3168: https://bugzilla.kernel.org/show_bug.cgi?id=204151 It suggests that the issue is fixed in kernel version 5.5 and later. I believe that Ubuntu 20.04 LTS uses kernel version 5.4.

I suggest that you download the iso for Ubuntu 20.10 which currently uses kernel version 5.8. Next, try a live session, also known as “Try Ubuntu.”

Does your wireless work as expected? Are there any clues in the message log?

dmesg | grep iwl

Do all other functions; that is email, web browser, etc. work as expected? If so, I suggest that you install it.

EDIT: Please check the integrity of the firmware file:

md5sum /usr/lib/firmware/iwlwifi-3168-29.ucode

We hope you see: 35ba5d5a8bdd6ff453106d268eda957e

If not, please do:

sudo apt install –reinstall linux-firmware

Reboot and check:

dmesg | grep iwl

Any improvement?

If not, rename the -29 version so that the system instead loads -27:

cd /usr/lib/firmware/
sudo mv iwlwifi-3168-29.ucode  iwlwifi-3168-29.bak

Reboot. Is there any improvement? If not, revert the change and reboot:

cd /usr/lib/firmware/
sudo mv iwlwifi-3168-29.bak  iwlwifi-3168-29.ucode

  • Note, Ubuntu 20.04.2 ISO is available and uses HWE kernel 5.8, the same as Ubuntu 20.10. One should be able to stay in LTS and get the kernel version 5.8.

  • The one which I installed on my laptop is ubuntu 20.10. The kernel version is 5.8. And the bug is not fixed maybe. because the wifi issue is not solved yet on my laptop.

  • "I have installed ubuntu 20.04LTS" Hence my confusion. Please see my edit above in a few moments.

  • the problem didn't solve yet. Maybe this issue is a major issue and ubuntu should fix it.

  • As Intel supplies the hardware, the driver and the firmware, I'm not sure Ubuntu can do much about it. I suggest that you start here: bugs.launchpad.net/ubuntu
