Please take a look at this commit message http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=89f927af7f3389e20c8ad24abfb3d1369f3ffc10 I tested it successfully using an AR9462 adapter and a kernel 4.0. >From what I understood from tx99_power parameter doing; echo 10 > /sys/kernel/debug/ieee80211/phy0/ath9k/tx99_power will set the tx power to 5 dBm Please try this shell script: http://pastebin.com/ANZwVmbp ./test-wifi.sh 1 HT40+ First arg is the channel number,second one is the HT mode. This script set the txpower to 20dBm. I'm almost sure that there is a version of ART for Linux somewhere but you may need to sign NDA, or special licence with QCA.
