Meu sistema operacional é o Ubuntu 17.04 em um sistema de 32 bits, e hoje a conexão Wi-Fi da internet parou de funcionar, mas ele detecta a rede wifi e mais eu posso conectar-me ao meu hotspot de telefone. Como posso consertar isso?
Aqui está o diagnóstico da rede:
Quando conectado ao meu iPhone (para conectar sua conexão de internet ao meu computador)
Quando conectado ao ponto de acesso problemático 1616 - miinternet.cl :
