Hi all,
Just for testing porpouse, I'm doing some test with OpenWrt (ath9k
driver), TX power and regulatory domains, and I obtaing strange results.
I compiled stable image with CONFIG_ATH_USER_REGD option, I pathed
cfg80211.ko module (reghack says ath.ko it's already pathced) with
reghack and I tested severals channels: 100, 120 and 140 in differents
hardware: Mikrotik and Compex.
* Mikrotik
- Channel 100 => Tx-Power 14
- Channel 120 => Tx-Power 21
- Channel 140 => Tx-Power 14
* Compex
- Channel 100 => Tx-Power 23
- Channel 120 => Tx-Power 23
- Channel 140 => Tx-Power 23
In both, channel 100 doesn't configured in boot sequence with
/etc/config/wireless configurations values. If I configured manually
works correctly but output the following debug message:
hxxp://pastebin.com/eDKv8dMf
I create new regulatory.bin without limitations and this is the output
of the command iw reg get:
country 00:
(2400 - 2483 @ 40), (N/A, 30)
(5140 - 5860 @ 40), (N/A, 30)
But the iw phy0 info command output is:

* 5825 MHz [165] (23.0 dBm) * 5825 MHz [165] (21.0 dBm)
What Tx-Power depends: hardware? channel? regulatory domain?
Thanks for all.
King regards.
