I have tried every method off internet but nothing seems to be working. I would be very thankful for any help.

I have installed linux-firmware package and I have tried replacing the iwlwifi*.ucode from intel site to /lib/firmware but it does not work

Hello @Junichiro

Thank you for posting on the Intel® communities.

In order to check this further, could you please provide the following information?

1- Is the Intel® Wi-Fi 6 AX201 the original wireless adapter that came pre-installed in your system? Or did you replace/integrate it?

2- When you said "Wifi not Working", do you mean you cannot connect/detect any wireless network? Or is the Wireless connected but with no Internet access? Do you have access to your local wireless LAN at home/office? Please provide details

3- Were you able to have your wireless connection in a normal/expected performance before? If yes, were there any recent changes like operating system or firmware updates?

4- Please verify the following and provide details/outcome:

• The reference table of Wireless adapters and corresponding kernel versions is available by the link: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi In the table under Firmware section you should find the recommended firmware for Intel® Wi-Fi 6 AX201 160MHz
• The latest FWs are available by the following link:​ ​https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/

5- If the kernel version corresponds to the Wireless adapter as per steps on point # 4, please type the following command to the terminal: # lspci​ and provide us with the outcome.

Best regards,

1- Is the Intel® Wi-Fi 6 AX201 the original wireless adapter that came pre-installed in your system? Or did you replace/integrate it?

Answer: Yes the Intel Wi-FI 6 AX201 is the original wireless adapter that came pre-installed.

2- When you said "Wifi not Working", do you mean you cannot connect/detect any wireless network? Or is the Wireless connected but with no Internet access? Do you have access to your local wireless LAN at home/office? Please provide details

Answer: I mean the device does not show up. There is no option to enable or use Wi-Fi. ip a gives following

       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

As you can see the wifi device does not show. And yes I have access to local wireless LAN at home.

3- Were you able to have your wireless connection in a normal/expected performance before? If yes, were there any recent changes like operating system or firmware updates?

Answer: Yes I was able to connect and use wireless connection before. Wi-Fi works fine while using windows  OS. But after I installed linux the wifi does not work no matter which distro I use. There was a BIOS update but the wifi was already not working before that.

4- Please verify the following and provide details/outcome:

• The reference table of Wireless adapters and corresponding kernel versions is available by the link: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi In the table under Firmware section you should find the recommended firmware for Intel® Wi-Fi 6 AX201 160MHz
• The latest FWs are available by the following link:​ ​https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/

Answer: I tried doing both but it still does not work. dmesg output still show no suitable firmware found.

Hello Junichiro

We are still working on this issue. However, We need more details to continue working on this. Could you please confirm/provide the following information?

1) Are you using a dual-boot with Windows* and Linux operating systems?

If so, may we know if you try to disable the 'fast-boot' option as suggested in Intel iwlwifi support website: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled

2) Regarding the issue, please confirm if you mean that the WiFi works fine on Windows 10, but WiFi never work on Linux?

3) Output of these commands: 

• #uname -a
•  #rfkill list
• #modinfo iwlwifi
• #lsmod | grep iwlwifi
• #sudo lshw -C network

4) The complete dmesg: # dmesg >dmesg.log

1) Are you using a dual-boot with Windows* and Linux operating systems?

Answer: No, I am not using a dual-boot. And I have the fast boot option disabled in the bios.

2) Regarding the issue, please confirm if you mean that the WiFi works fine on Windows 10, but WiFi never work on Linux?

Answer: Yes, The laptop came installed with windows 10 and the WiFi worked fine on Windows 10. But WiFi does not work in Linux. I have an external adapter and the WiFi works fine using the external adapter.

Hello Junichiro

After checking this further, it seems like the driver is trying to load the wrong ucode. Please try to load the firmware manually following these steps:

1) Download and install the latest Linux firmware https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

e.g. linux-firmware-20210511.tar.gz

2) Do '# cp iwlwifi-Qu*.ucode /lib/firmware' for the following AX201 FW

firmware: iwlwifi-QuQnj-b0-jf-b0-62.ucode

firmware: iwlwifi-QuZ-a0-jf-b0-62.ucode

firmware: iwlwifi-QuZ-a0-hr-b0-62.ucode

firmware: iwlwifi-Qu-b0-jf-b0-62.ucode

firmware: iwlwifi-Qu-c0-hr-b0-62.ucode

firmware: iwlwifi-QuQnj-b0-hr-b0-62.ucode

firmware: iwlwifi-Qu-b0-hr-b0-62.ucode

3) Load the driver # sudo modprobe iwlwifi

Please let us know if this helps or if the issue persists.

Still not working. But the dmesg log about iwlwifi changed

sudo dmesg | grep iwlwifi   gives following:

Hello Junichiro

Thank you for your patience in this matter and for your efforts.

After checking this further, the dmesg log about iwlwifi changed after you manually updated the Linux Firmware. In order to continue investigating this, we would really appreciate it if you could provide all logs again:

1. #rfkill list
2. #modinfo iwlwifi
3. #lsmod | grep iwlwifi
4. #sudo lshw -C network
5. And the complete dmesg # dmesg >dmesg.log

Hello Junichiro

In order to continue working on this, we needed some logs requested in our previous posts; however, since we have not heard back from you, we will proceed to close this thread now.

Since the wireless card works fine in Windows*, our last recommendation is to contact the Linux distro support team/community for more troubleshooting steps or your Original Equipment Manufacturer (OEM) SAMSUNG* to verify compatibility with Linux operating systems and additional debugging. For your convenience, here is the link to SAMSUNG* Support.

If you need any additional information, please submit a new question as this thread will no longer be monitored.
