Eu tenho um problema com minha conexão de rede. Eu tenho usado o mesmo laptop com Ubuntu e a mesma conexão há mais de um ano e, de repente, ontem a conexão parou de funcionar (sem fio e com fio). Eu testei com outro computador e a conexão está bem (sem fio e com fio).
Eu tenho lido posts semelhantes, mas ainda não encontrei uma solução. Eu tentei alguns comandos que estou postando aqui (meu sistema está em espanhol, então eu o transcrevi para o inglês, talvez os termos não sejam precisos):
grep -i eth /var/log/syslog | tail
