Buenas tardes.
Últimamente he estado muy liado con la universidad y no he podido postear demasiado.
Hoy he sacado un rato libre y me he programado un parcheador de los datos de calibración de cualquier ath9k.

Como podéis ver ya no se fuerza el regdomain a Estados Unidos.
He probado con éxito el WiFi en los canales 12 y 13.
De esta manera también se habilita el WiFi en otros canales como el 14, para la banda de 2.4GHz. Sin embargo, este canal no se puede usar en Europa.
http://en.wikipedia.org/wiki/List_of_WLAN_channelsEn cuanto tenga tiempo publico la aplicación para parchear los datos de calibración y hago un tuto en un hilo a parte, ya que esto vale para cualquier dispositivo con WiFi ath9k. Espero no dejaros con la miel en los labios por mucho tiempo, pero tenéis que entender que la universidad es lo primero :$.
Un saludo, Noltari.
