Hi Gopal,

Thanks for reaching out about the Wi-Fi issue on your Lenovo ThinkPad T16 Gen 4!

I can see you're dealing with missing firmware for your Intel Wi-Fi adapter, and I'm here to help get this sorted out.

Your system can see the Intel Wi-Fi adapter just fine, but it's missing the specific firmware files needed to get it up and running.

Please try the troubleshooting steps:

The easiest fix is updating to the latest stable Linux kernel, which already has all the firmware files you need packed in.

Install the latest stable Linux kernel (7.0.3) from The Linux Kernel Archives
Once the new kernel is running, your Intel Wi-Fi should work right away since all the required firmware is already there

Please take note that if the firmware is not included, you can manually install it, but in order for us to provide the exact firmware, please provide the adapter model.

Those firmware files you mentioned (iwlwifi-bz-a0-gf-a0-*) are actually for an AX211 adapter, while the PCI ID you're seeing points to a different model. To give you the most accurate help, could you share the exact model of your Wi-Fi adapter? You can usually find this in your system specs or by running # lspci in your terminal.

A few questions to help me out:

When did this issue start happening?
Any recent changes before it occurred (system updates, driver changes, etc.)?
What's the exact model of your ThinkPad T16 Gen 4? If you have a link to the product page or model number, that'd be great!

I'd recommend trying the kernel update first since it's usually the most straightforward approach. If you run into any issues or need help with the process, just let me know and I'll walk you through it.

Looking forward to hearing how it goes!

Best regards

When did this issue start happening?

---> Laptop came with ubuntu 24.04 but I needed ubuntu 22.04 due to software dependency. so after flashing 22.04 this issue started.

Any recent changes before it occurred (system updates, driver changes, etc.)? --->No.
What's the exact model of your ThinkPad T16 Gen 4? If you have a link to the product page or model number, that'd be great! ----> attached screenshot of product info.

Looking forward to your response!!

Thanks,

Gopal

Hi Gopal,

Thank you for your response.

I can see that your adapter model is Intel(R) Wi-Fi 6E AX211 160MHz.

Could you please try to manually install and load the firmware iwlwifi-so-a0-gf-a0-89 needed for this adapter?

# sudo cp iwlwifi-* /lib/firmware/'

# sudo modprobe iwlwifi

You can check this link for kernel/git/firmware/linux-firmware.git - Repository of firmware blobs for use with the Linux kernel

We're looking forward to your response.

Hi Jonzyl_Intel,

I downloaded ucode file from this location: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/intel/iwlwifi

I see below dmesg.

In your previous comment, you mentioned "iwlwifi-so-a0-gf-a0-89". This seems different than what is mentioned in dmesg. Please let me know which one exactly works. As of now both of them are not working. Also Can you help attach fimrware here as an attachment? That will help quickly.

Thanks,

Gopal

Hi Gopal,

Thank you for your response.

I apologize for my previous response.

Could you please update your firmware files below:

iwlwifi-so-a0-gf-a0-89

iwlwifi-so-a0-gf-a0.pnvm

You can check this link for the firmware files: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/intel/iwlwifi

Additionally, if the issue persists, try to install the stable version 6.19.14 and let us know the outcome.

We look forward to your response.
