Paso 5: El dispositivo se conecta a un servicio
Por una política de Shill, el dispositivo se conecta automáticamente al servicio 0. Si el usuario elige conectarse a otra red Wi-Fi, es posible que se seleccione otro número de servicio.
Registros
- En wpa_supplicant se define la prioridad de las redes. Si una red es más conveniente (por su política de seguridad, la intensidad de la señal, etc.), puedes aumentar su valor de prioridad. El valor de grupo de prioridad de Chrome no cambia; en los registros siempre aparece como grupo de prioridad 0.

Paso 8: Se establece el protocolo de handshake de 4 vías entre el dispositivo y el punto de acceso
Para crear una clave de encriptado de datos mediante la clave compartida (clave maestra de pares o PMK), wpa_supplicant establece el protocolo de handshake de 4 vías entre el dispositivo y el punto de acceso. Si el dispositivo se conecta a una red de Protocolo de autenticación extensible (EAP) 802.1X, tendrá que pasar primero el proceso de autenticación de EAP.

Paso 9: Se establece el protocolo de handshake de claves de grupo entre el dispositivo y el punto de acceso
Para que el dispositivo pueda recibir mensajes de multidifusión o difusión cifrados, wpa_supplicant establece el protocolo de handshake de claves de grupo entre el dispositivo y el punto de acceso. El punto de acceso envía una clave transitoria de grupo (GTK) al dispositivo y este la acepta.

Paso 10: El dispositivo configura el DHCP
Después, se configura el DHCP. La primera vez que el dispositivo se conecta a una red, envía un mensaje DHCP DISCOVER a su subred. El servidor DHCP ofrece una dirección IP al dispositivo. Este hace una petición formal de la dirección IP con el mensaje DHCP REQUEST. El servidor DHCP acusa recibo de la petición con el mensaje DHCP ACKNOWLEDGE. Entonces, el dispositivo modifica su configuración para usar esa IP.
Registros
- Se ha establecido conexión con la Wi-Fi. Para ver la línea, usa
CTRL-EVENT-CONNECTED. - El servicio Shill tiene que recibir los datos de su IP del servidor DHCP. El estado de Wi-Fi de Shill se cambia a "completada". El estado del servicio Shill se cambia a "configurando".
- El servicio DHCP se inicializa con el identificador de proceso (pid) 14295.
- En los registros se indica el identificador de la transacción (xid) DHCP 0x63526f44.
- Además de proporcionar la dirección IP del dispositivo, el servidor DHCP ofrece más información (la dirección IP de la pasarela y datos del servidor de nombres de dominio o DNS, por ejemplo). Dicha información se muestra en las líneas con
Processing Keys. - Cuando el dispositivo recibe la dirección IP, la registra como la pasarela predeterminada en su tabla de reenvío de IP. No obstante, primero tiene que resolver la dirección MAC de la pasarela a partir de la dirección IP mediante el protocolo de resolución de direcciones (ARP).
