Wifi not detected after trying to update firmware

My T16 AMD laptop has troublesome wifi firmware that required these files on my debian setup, which worked immediately after replacing the files. However, doing the same steps on fedora (/lib/firmware/ath11k/WCN6855/hw2.0) made my laptop unable to detect any wifi. Doing the instructions on the README also did nothing.

I need to update the firmware files manually using this repository, thank you

Can you post the output of the sudo dmesg | grep -i ucode command? Also, do you have atheros-firmware package installed?

If you currently have the files there, try :

sudo dracut -f && sudo reboot

You can check the logs after booting up the computer again for more info:

dmesg | grep ath11k

[    3.979467] amdgpu 0000:04:00.0: amdgpu: RAS: optional ras ta ucode is not available
[    3.991914] amdgpu 0000:04:00.0: amdgpu: RAP: optional rap ta ucode is not available
[    3.991918] amdgpu 0000:04:00.0: amdgpu: SECUREDISPLAY: securedisplay ta ucode is not available

I don’t know, how do i check?

Just do sudo dnf install atheros-firmware and it will be installed if it is not already installed.

yes it is installed

Did you do the dracut part and the reboot?

yes, before doing the second part. i will do it again

Also note :

That’s a different directory it’s looking for. You’re placing it in hw2.0 it’s looking for hw2.1

You should include details like Fedora version, and whether the system is fully updated. journalctl --no-hostname -b -g wifi |cat (the |cat will ensure that very long lines are wrapped) may have helpful. Note that you will benefit when other users with similar issues can find this topic with web searches.

Fedora had a recent firmware update:

I have sometimes need to manually install or rename firmware blobs while waiting for the update package. You may need to touch up selinux context when install packages manually, but journalctl should have details if that is the issue. Also note that some device firmware updates are tied to vendor system firmware updates.

Installed today, so it is Fedora 40, and have fully updated it

it points back to my hw2.0 folder. The repository also shows to put in the hw2.0 folder, so should i just move my bin.xz files from the hw2.0 folder to the hw2.1 folder?

Put it in the 2.1 folder to test, then do the dracut instructions from previous comment. It may be that it can’t read the symbolic link.


i also had to compress the files from the repository using xz -C crc32 firmware.bin

Thanks so much you 3

It’s not like I haven’t had my battles with ath11k-xX [OpenWRT] and others in the past. . .

this QCNFA765 wifi driver is not friendly to beginners like me for sure…thanks again and goodbye!

To confirm that linux-firmware-20240610-1.fc40.noarch has different (outdated?) files:

  • Fedora package version:
