• Capacidades WiFi de un adaptador inalámbrico a usar con hostapd

    Si quieres saber las wifi capabilities de tu tarjeta inalámbrica para saber luego cuáles capacidades debes indicarle al archivo .conf del demonio hostapd, siempre puedes ejecutar:

    iw list

    … y tomar nota de ellas.

    Pero, para saber como indicarle a hostapd que use esas capacidades deberás conocer el parámetro de cada una de ellas. Y para ello, esta lista:
