IP, mas sem conexão com a internet

Question

Acabei de obter um computador antigo em execução no Mint 16 Petra e tento conectá-lo à Internet.

Embora o gerenciador de rede se conecte ao Wi-Fi, eu não posso nem efetuar o ping 8.8.8.8. O Firefox exibe um "erro de servidor" e o Chrome claimes "DNS_probe_finish_no_internet".

De que boa leitura, a maioria dos diagnósticos começa com ifconfig e nm-tool, então aqui está a saída.

Aqui está o ifconfig
