Description vanlaw233 2025-05-11 20:50:18 UTC

My platform is ROG Zephyrus G14 GA401IV with 222(latest) version BIOS.
Before a Kernel Panic screen, my wireless card didn't show connection speed and seems like only connect with 2.4Ghz but it work, now it totally didn't work.

Tried downgrade to 6.14.5 or switch to linux-zen, both didn't working.

And this is my relation information:

Comment 1 vanlaw233 2025-05-11 20:53:32 UTC

And I tried boot to live environment with Ubuntu 24.10 and OpenSUSE Tumbleweed, This wireless card is worked all.

Comment 2 Lucas Frendorf 2025-05-12 14:36:24 UTC

Exact same issue for me 
Downgrading both linux-firmware and linux-firmware-qcom to version 20250408 seems to fix the issue
Unsure if downgrading (linux-firmware-qcom) is required though

Comment 3 Jeff Johnson 2025-05-12 22:11:25 UTC

There have been a couple of reports of old versions of the ath12k driver not working correctly with the latest ath12k firmware. The development team is looking into this. Downgrading firmware or moving to the mainline v6.15-rc kernel are the current workarounds.

Comment 4 vanlaw233 2025-05-13 04:12:49 UTC

Now I changed back to AX200 as a solution.

Comment 5 zmiguel 2025-05-13 13:23:24 UTC

I have the same issue on Arch, The suggestion from Jeff Johnson:

> There have been a couple of reports of old versions of the ath12k driver not

Does not seem to work, as the issue remains when running 6.15.0-rc6-1-mainline, the only way to get it to work again for me is using the LTS kernel (6.12.28-1-lts)

Comment 6 Jeff Johnson 2025-05-13 14:34:04 UTC

Latest report from the development team is that this issue is specific to certain cards, so upgrading the kernel version won't help (issue exist with Linus' release tree). So rolling back firmware is the current workaround when this issue is encountered.

Following firmware should work will all cards, but does not support the multi-link operation (MLO) feature:

Comment 7 Shmerl 2025-05-16 06:37:43 UTC

Will there be some future fix for affected cards to use separate firmware in the upstream repo or may be a fix in the kernel driver itself?

Comment 8 Sydney van der Heijden 2025-05-16 10:48:08 UTC

Having the same issue with my T14 Gen 5 AMD using qualcomm Wi-Fi 7 NCM825. Any other fixes possible?

Comment 9 Daniel Hakim Jamaluddin 2025-05-17 16:46:08 UTC

Same here having the same issue with T14 Gen 5 AMD using Qualcomm Wi-Fi 7 WCN785x.
Using Fedora 42 and Linux kernel 6.14.6-300.fc42.x86_64.

Tried to downgrade but seems dnf's repository packages only have 'kernel.x86_64 6.14.0-63.fc42' as the oldest kernel version.

Anyone find any other ways to temporarily fix the issue?

You can downgrade the atheros-firmware package to version 20250509.
This should fix it. Tested with kernel 6.14.6-300 on Fedora 42.

I just actually downgraded to older version atheros-firmware atheros-firmware-20250311-1.fc42, works fine and temporarily fixed the issue. Tested with the 6.14.6-300 on Fedora 42.

I might leave it unchange for now until this issue has been resolved. Thank you btw.

Downgrading to atheros-firmware-20250311-1.fc42 finally fixed it for me.

Comment 13 Jeremy McCoy 2025-05-20 17:34:20 UTC

Same issue here with Lenovo T14s Gen 6 and Arch Linux with CachyOS kernel and repos. The proposed firmware downgrade at https://unix.stackexchange.com/a/794865/77876 did not work for me, but downgrading to kernel 6.12.29-1-cachyos-lts-lto did restore WiFi functionality.

Comment 14 linuxisforall 2025-05-20 21:06:10 UTC

same issue here.

my motherboard is MAG Z790 TOMAHAWK MAX WIFI (MS-7E25)

and thge wifi chip is Qualcomm Technologies, Inc WCN785x Wi-Fi 7(802.11be) 320MHz 2x2 [FastConnect 7800] (rev 01)

After Linux kernel 6.14.5 I can't use WIFI anymore, even the 6.15rc is affected by this issue.

Comment 15 Mario Limonciello (AMD) 2025-05-23 18:29:04 UTC

A fix has been landed upstream.  You can pick it up here.

Comment 16 Mark Dietzer 2025-05-23 18:43:35 UTC

The fix does not seem to work for me. Still getting the same errors (using latest 6.15-rc). Only working fix for me currently is downgrading the firmware to the previous known good.

I've relayed this information to the firmware team.

And reopened the ticket.
