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:
Capacidades HT (WiFi 4):
HT20/HT40 : [HT20] o [HT20-] o [HT20+] y [HT40] o [HT40-] o [HT40+] Static SM Power Save : [SMPS-STATIC] ? Dynamic SM Power Save : [SMPS-DYNAMIC] ? SM Power Save disabled : No poner nada de SMPS en el archivo .conf ?
