This is Atheros AR9271 .

Could you test current upstream driver using compat-wireless-next from http://people.redhat.com/sgruszka/compact_wireless.html

If it still not work, please attach dmesg command output.

Comment 4 Edward Town 2011-08-17 04:54:24 UTC

It finally worked!

When I run dmesg I found this:
[   18.596309] ath9k_htc 1-3:1.0: ath9k_htc: Please upgrade to FW version 1.3

So I downloaded htc_9271.fw from http://wireless.kernel.org/download/htc_fw/1.3/ and copy it to /lib/firmware.

Thank you!
