Eu recentemente decidi experimentar o Linux, limpei meu disco rígido e instalei o Ubuntu Mate 16.04. Vai mostrar que eu tenho uma conexão wifi, mas a internet não vai carregar. Eu tinha desligado o ipv6 ontem de manhã e a internet funcionou um pouco, mas agora não está funcionando novamente. Nada é difícil ou mole desativado, verifiquei a lista de rfkill. Todos os meus outros dispositivos funcionam no Wi-Fi e reiniciei o computador e o roteador inúmeras vezes. Alguma ideia do que pode ser o problema?
Estou executando um Lenovo Ideapad 310.
