Hi

I have been working on getting the Wifi working on a pair of Asus
UX3407NA and UX3607OA laptops.
Both came with QCC2072 WLAN cards.
The current linux-firmware (2026-08-10)
"ath12k/QCC2072/hw1.0/board-2.bin" does not contain board names for
these devices:
PCI vendor/device:       17cb:1112
subsystem vendor/device: 105b:e14f
qmi-chip-id:             33
qmi-board-id:            255

The current firmware will work with both laptops if I add the
following two lines to ath12k/QCC2072/hw1.0/board-2.bin:
bus=pci,vendor=17cb,device=1112,subsystem-vendor=105b,subsystem-device=e14f,qmi-chip-id=33,qmi-board-id=255,variant=UX3407Q
bus=pci,vendor=17cb,device=1112,subsystem-vendor=105b,subsystem-device=e14f,qmi-chip-id=33,qmi-board-id=255

Relevant dmesg from the UX3407NA laptop before the modification:
