I've been trying off and on to get a Qualcom Atheros to work. lspci
shows it as AR9227. It's a plain PCI card. I've come to the
conclusion that there must be a firmware blob for this card. I'm not
sure which one it will use. Ubuntu /lib/firmware has various choices
under the "ath9k" directory. Does anyone know the short answer to
this? Are firmware blobs always compiled in the kernel? Are the
blob files always a *.bin file?
Sometimes firmware has a .fw extension. I have a Qualcomm Atheros
AR9287 Wireless Network Adapter (PCI-Express) on my development
system, but don't use it very much. Right now I am not using
firmware, but the kernel recognizes it:
[ 5.886718] ath: EEPROM regdomain: 0x809c
[ 5.886718] ath: EEPROM indicates we should expect a country code
[ 5.886719] ath: doing EEPROM country->regdmn map search
[ 5.886719] ath: country maps to regdmn code: 0x52
[ 5.886720] ath: Country alpha2 being used: CN
[ 5.886720] ath: Regpair used: 0x52
My kernel config is
CONFIG_ATH_COMMON=y
CONFIG_WLAN_VENDOR_ATH=y
CONFIG_ATH9K_HW=y
CONFIG_ATH9K_COMMON=y
CONFIG_ATH9K=y
CONFIG_ATH9K_PCI=y
CONFIG_ATH9K_AHB=y
CONFIG_ATH9K_RFKILL=y su
CONFIG_ATH9K_PCOEM=y
CONFIG_ATH9K_HWRNG=y
and I have
$ ls /sys/class/net
br0 eth0 lo sit0 wlan0
so the card is recognized. If I do
Bruce, I'll stick with you because I want it compiled in the kernel.
This is from the kernel log, I was using the same settings, minus the
"CONFIG_ATH9K_HWRNG=y". Didn't help, still complaining about error 12
I have tried the module setup, same error 12. I have no clue what that
error is pointing to. This system works with Ubuntu.

I don't know that I can help any more. I only have intel CPUs. Also,
my kernel is slightly dated (4.20.8 built in February for LFS 8.4).
About the only thing I can recommend is to try installing the latest
version of a distro (My first choice is debian) and see if they
recognize the device.
Note, please reply to lfs-support so others can search for similar problems.
