Eu tenho o Ubuntu 16.04 e uma conexão com fio que cai aleatoriamente.
Eu sei que tem havido perguntas semelhantes lá fora. A maioria das respostas e soluções sugere o download do driver realtek correto (r8168) e a lista negra do r8169.
Eu já tentei isso e não funciona.
Aqui está a saída de vários comandos
