Missing firmware for Intel(R) Wi-Fi 6 AX201

[zpp1]

I just got a new Laptop (Redmi Book 15 pro 2025) with Intel Wi-Fi adapter AX201.  It does not work with the newest Linux kernel.

Here is output of "sudo dmesg | grep iwlwifi"

[ 4.734665] iwlwifi 0000:00:14.3: Detected crf-id 0x1300504, cnv-id 0x80930 wfpm id 0x80005b30
[ 4.734672] iwlwifi 0000:00:14.3: PCI dev 7740/0274, rev=0x461, rfid=0x10a100
[ 4.734674] iwlwifi 0000:00:14.3: Detected Intel(R) Wi-Fi 6 AX201 160MHz
[ 4.734927] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-bz-b0-hr-b0-94.ucode failed with error -2
[ 4.735067] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-bz-b0-hr-b0-93.ucode failed with error -2
[ 4.735082] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-bz-b0-hr-b0-92.ucode failed with error -2
[ 4.735083] iwlwifi 0000:00:14.3: no suitable firmware found!

On the 15th, the firmware was added, but it is iwlwifi-bz-b0-hr-b0-96.ucode , which is too high.

May I ask when you're going to release the firmware for these devices?

Hello Mike_Intel，

Actually, you only need to provide:

[4.734927] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-bz-b0-hr-b0-94. ucode failed with error -2
[ 4.735067] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-bz-b0-hr-b0-93.ucode failed with error -2
[ 4.735082] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-bz-b0-hr-b0-92.ucode failed with error -2

These three firmware issues can be easily resolved.

Best regards,

你好，Mike_Intel，

1.The original operating system was Windows 11.

2.The Linux operating system currently in use is Fedora41, 6.13.5-200.fc41.x86_64.

3.This is an incorrect screenshot:

4.Now my computer cannot recognize the WiFi firmware, resulting in a lack of wireless network identification on the computer.

I hope you can help me solve the problem！

Hello zpp1,

Thank you for providing the requested information. I truly appreciate you providing us the information we need to properly investigate this issue. I just hope to clarify some more information, so we can fully isolate the root cause of the issue. Please help share the following:

1. Can you confirm that the AX201 wireless adapter was properly detected by the system device and works fine with Windows OS?
2. Please confirm if this is the actual system device that you have. https://www.mi.com/redmibook/pro15/specs

 I hope to hear from you so I may continue with the investigation.

Hello JeanetteC，

Thank you for your follow-up. Regarding the information you need to confirm, my response is as follows:

AX201 adapter status confirmation:
The device has been correctly recognized by the Windows 11 system (Device Manager shows "Intel (R) Wi Fi 6 AX201 160MHz")
Basic functions are normal (able to scan Wi Fi networks and connect).

Equipment model correction:
The actual device is Redmi Book Pro 14 2025 model (correct specification page: https://www.mi.com/prod/redmi-books/14-pro-2025/specs）Different specifications from the previously mistakenly sent Redmi Book Pro 15.

Looking forward to your further guidance.

Best regards,

zpp1.
