Etapa 5: o dispositivo se conecta com um serviço
Devido a uma política, o chamariz especifica que o dispositivo se conecte automaticamente com o serviço. Se o usuário optar por se conectar com outra rede Wi-Fi, talvez um número de serviço diferente seja selecionado.

- O wpa_supplicant prioriza as redes. Se uma rede for preferível, com base na política de segurança, na intensidade do sinal etc., você poderá aumentar o valor da prioridade dela. No Chrome, o valor do grupo de prioridade não é alterado. Ele é sempre 0 nos registros.

Etapa 8: o dispositivo e o ponto de acesso executam um handshake de quatro vias
Para criar uma chave de criptografia de dados usando a chave compartilhada (chave mestra de paridade ou PMK), o wpa_supplicant executa um handshake de quatro vias entre o dispositivo e o ponto de acesso. Se o dispositivo se conectar a uma rede com o protocolo de autenticação extensível (EAP, na sigla em inglês) 802.1X, primeiro ele precisará executar o processo de autenticação do EAP.

Etapa 9: o dispositivo e o ponto de acesso executam um handshake de chave de grupo
Para permitir que o dispositivo receba mensagens de broadcast e multicast criptografadas de um ponto de acesso, o wpa_supplicant executa um handshake de chave de grupo entre o dispositivo e o ponto de acesso. O ponto de acesso envia a chave transitória de grupo (GTK, na sigla em inglês) para o dispositivo, que a reconhece.

Etapa 10: o dispositivo configura o DHCP
Em seguida, o DHCP é configurado. Quando se conecta pela primeira vez com uma rede, o dispositivo transmite uma mensagem DHCP DISCOVER para as sub-redes. O servidor DHCP oferece um endereço IP para o dispositivo. O dispositivo solicita formalmente o endereço IP com a mensagem DHCP REQUEST. Essa mensagem é reconhecida pelo servidor DHCP com a mensagem DHCP ACKNOWLEDGE. O dispositivo então atualiza as próprias configurações para usar as informações desse IP.
Registros
- A conexão Wi-Fi é concluída. Veja a linha com
CTRL-EVENT-CONNECTED. - O serviço de chamariz precisa receber as informações do IP do servidor DHCP. O estado do Wi-Fi do chamariz é alterado para "concluído". O estado do serviço de chamariz é alterado para "configurando".
- O serviço do DHCP é inicializado usando o código de processo (pid) 14295.
- Os registros indicam o código da transação do DHCP (xid) 0x63526f44.
- Além de fornecer o endereço IP para o dispositivo, o servidor DHCP também oferece outras informações, como os detalhes do servidor de nomes de domínio (DNS, na sigla em inglês) e o endereço IP do gateway. Você pode ver essas informações adicionais nas linhas com
chaves de processamento. - Após receber o endereço IP, o dispositivo o registra como gateway padrão na tabela de encaminhamento de IP. Mas primeiro ele precisa determinar o endereço MAC do gateway do endereço IP usando o protocolo de resolução de endereços (ARP, na sigla em inglês).
