Estou usando o hostapd no Alpinelinux (kernel 4.14.69, Intel (R) Centrino (R) Advanced-N 6205 AGN, módulo sem fio REV = 0xB0).
Primeiro, quero fazer o dispositivo sem fio como AP e estação. Então eu corri seguindo comandos
# iw dev wlan0 interface add wlan0_sta type managed addr 12:34:56:78:ab:cd
# iw dev wlan0 interface add wlan0_ap type managed addr 12:34:56:78:ab:ce
Em seguida, execute o hostapd contra wlan0_ap. O SSID apareceu. Associativo, mas DEAUTH do lado do cliente em 3 segundos. wpa_supplicant disse "4 way handshake failure".
Então eu corri o hostapd contra wlan0, com os mesmos confs. Tudo acabou de funcionar.
Então, pergunto-me o que mais devo fazer ou se o meu dispositivo não suporta isto.
