Mint 13 Cinnamon - Regulatory domain

[Tucuman]

Hi everybody

I have an Ubiquiti WiFiStation EXT adapter ---> [Atheros AR9271]

By default its Regulatory domain is US, but I need to use channels >11, so with the following command I try to set it to Spain

sudo iw reg set ES

---> dmesg | grep country

[ 15.262888] ath: EEPROM indicates default country code should be used
[ 15.262893] ath: doing EEPROM country->regdmn map search
[ 15.262898] ath: country maps to regdmn code: 0x3a
[ 15.271586] cfg80211: Calling CRDA for country: US
[ 15.294960] cfg80211: Regulatory domain changed to country: US
[ 2180.633992] cfg80211: Calling CRDA for country: ES
[ 2180.641461] cfg80211: Regulatory domain changed to country: ES


The problem is that I can't "see" 12-13-14 channels

iwlist chan
lo no frequency information.

wlan1 11 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
Channel 03 : 2.422 GHz
Channel 04 : 2.427 GHz
Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz

And if I reboot the computer the Regulatory Domain is again in US ....
