>Synopsis: iwx loads incorrect firmware file for AX201
>Category: kernel
>Environment:
System : OpenBSD 7.7
Details : OpenBSD 7.7-current (GENERIC.MP) #51: Thu Jul 10 09:52:50
MDT 2025
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
On a fresh 7.7 installation with iwx firmware installed, the iwx
driver fails to function correctly and the issue persists even after
upgrading to -current.
The following error messages are displayed:
iwx0: using firmware iwx-QuZ-a0-hr-b0-77
iwx0: could not load firmware, 35
iwx0: failed to load init firmware
On a Linux 6.12 installation, the iwlwifi driver functions properly
with the same wireless device:
[linux]# dmesg | grep -i "wifi"

As shown in the log messages above, the iwlwifi driver successfully
loads the QuZ-a0-jf-b0-77 firmware. The iwx driver attempts to load
the QuZ-a0-hr-b0-77 firmware instead and fails.
>How-To-Repeat:
+ Install 7.7 on a system with specific wireless device.
+ Install the iwx firmware using `fw_update`.
+ Additionally, run `sysupgrade -s` to install -current.
>Fix:
The iwx driver code configures the device and sets the fwname
based on its pci id and hardware parameters. For this particular
wireless device, the rest of the configuration is fine but the
fwname is set incorrectly (i.e. different from what iwlwifi sets).
As a workaround to gain connectivity initially, the QuZ-a0-hr-b0-77
firmware file in /etc/firmware can be replaced with the correct one
under the same name:
# cd /etc/firmware
# mv iwx-QuZ-a0-hr-b0-77 iwx-QuZ-a0-hr-b0-77.bak
# ln iwx-QuZ-a0-jf-b0-77 iwx-QuZ-a0-hr-b0-77
The patch given below fixes the logic that sets the correct fwname
for this wireless device. The driver with this patch applied works
as expected:
