[ath9k-devel] WiFi USB Dongle using AR9271

[ath9k-devel] WiFi USB Dongle using AR9271

[Akhilesh Soni]

Guys,

I wish to integrate the USB wifi dongle with my STB the details of the
device given below. Please guide me how to proceed to get the device working
for my embedded kernel.

*USB Dongle Details *

USB vendor:product  0x0cf3:0x9271

*Embeded Device details  *

MIPS 32 bit   running embedded linux 2.6.22 kernel

I've also got LSDK-WLAN-9.2.0.114.tgz from my manufacturer but after
modifying the Makefile  I got the following modules

mkdir -p /lib/firmware/
cp ar9271.fw /lib/firmware
insmod drivers/wlan/adf/adf.ko
insmod drivers/wlan/asf/asf.ko
insmod drivers/wlan/os/linux/ath_hal/ath_hal.ko
insmod drivers/wlan/lmac/ratectrl/ath_rate_atheros.ko
insmod drivers/wlan/lmac/dfs/ath_dfs.ko
insmod drivers/wlan/lmac/ath_dev/ath_dev.ko
insmod drivers/wlan/lmac/ath_pktlog/ath_pktlog.ko
insmod drivers/wlan/umac/umac.ko

The last two kernel modules didn't got inserted. Some undefined symbol
errors. I also copied firmware file /lib/firmware

After all this I ran iwconfig config but couldn't see any wireless
interface.

The device is exactly similar to this
http://www.unex.com.tw/product/dnua-93f. I tried compat-wireless also and
applied 2.6.22 patches also but it didn't compile.

After all this I am clueless Please guide me which which driver I should use
to get it working.

Thanks in advance.

Regards,
Akhilesh

If you want to pursue this venue, this is a wrong place to ask.

Try working in two directions.  One is updating your kernel.  Maybe 
there is a newer kernel for your platform.  Or maybe you could apply 
patches that upgrade your kernel to 2.6.23 and even to 2.6.24.

Another approach is backporting compat-wireless to older kernels.  You 
only need to "bridge" two kernel versions to go from 2.6.24 to 2.6.22.
