Hello
I am using customised board using AR6003 WLAN.
After running insmod ath6kl.ko, ifconfig up and then iwconfig scan as
like the following,
It seems not to work.
ath6kl driver :
from 3.0 staging directory.
Firmware images :
from http://www.kernel.org/pub/linux/kernel/people/mcgrof/firmware/ath6k.tar.gz

ath6kl: module is from the staging directory, the quality is unknown,
you have been warned.

One more, my board is using 26Mhz for WLAN. which source code or
configuration file do I put this
information into ?
Thanks

The reason about failure of scanning is that Kernel bug with scan
