Capacidades WiFi de un adaptador inalámbrico a usar con hostapd
Si quieres saber las wifi capabilities de tu tarjeta wifi 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:
Capacidades HT:
