Hola a todos!
Veréis, he compilado openwrt branch 18.01 para este router y tengo un problema con la wlan de 5GHZ.
Resulta que si dejo la selección de canal en AUTO, (country SPAIN), la lista de canales disponibles es mayor que la que realmente es válida para España, que son los canales del 36 al 140 (5180 - 5700 MHZ). Esto es un problema porque los dispositivos wifi no detectan el punto de acceso cuando este se haya operando en un canal fuera del rango del país.
¿alguien sabe a que se puede deber esto y si hay alguna manera de ajustar los canales a la regulación correcta del país?
Adjunto capturas de varios comandos y del archivo /var/run/hostapd-phy1.cnf
Gracias por la ayuda!!!

Con este comando se ve que están incluidos los canales 149 al 165, y no debería ser así.
