Não consigo estabelecer conexão com a Internet com fio no meu PC de mesa. Ele tenta se conectar a "conexão com fio 1" e mesmo se, após minutos, ele finalmente (nem sempre) consegue "conectar" (de acordo com o ícone do indicador de rede no painel), eu não tenho Internet .. Existe alguma solução?

Eu tentei encontrar uma solução em postagens antigas sem sorte. Eu tenho esse problema desde lubuntu 15.10. Recentemente eu instalei a nova versão do lubuntu 16.04 que eu uso atualmente, mas até agora nenhuma diferença. O pc é dual boot e no outro sistema operacional tudo funciona bem. Então, eu suponho que não seja um problema de hardware. Eu não estou exatamente familiarizado com o Linux. Muito obrigado!
