Mais um teste a fazer quando a conexão cair... execute os comandos, veja se retorna.

sudo ifdown eth0
sudo ifup eth0

[juca 2]

Olá pessoal,segue o resultado do comando.

julio@julio-STI:~$ sudo ifdown eth0
[sudo] password for julio:
ifdown: interface eth0 not configured
julio@julio-STI:~$ sudo ifup eth0
Ignoring unknown interface eth0=eth0.
julio@julio-STI:~$

Me desculpem mais uma vez pelo retorno.

[zekkerj]

Mais alguns comandos...

grep -i networkmanager /var/log/messages | tail -50

Vamos ver se tem alguma pista pra desconexão no log do sistema.

[juca 2]

julio@julio-STI:~$ grep -i networkmanager /var/log/messages | tail -50
grep: /var/log/messages: Arquivo ou diretório não encontrado
julio@julio-STI:~$

[zekkerj]

Repita o comando com o arquivo "/var/log/syslog" ao invés do "/var/log/messages".

[zekkerj]

Vc pegou essa saída na hora em que a conexão caiu?

[juca 2]

Não tinha caído não Zekkerj, estava ativa

[zekkerj]

Então aguarde o momento da queda e repita o comando, pra gente comparar o comportamento do NM.
