sem muita carga na máquina, subitamente ficou ocupado e não respondeu. não podia responder ao movimento do teclado ou do mouse, nem se moveria para outro tty. existe algum log que pode sugerir o problema. Alguém pode ajudar a identificar o problema?
EDIT: às vezes também a minha internet fica parada; Eu não consigo ver nenhum pacote passando usando tcpdump
. Eu tenho que reconectar novamente à rede wifi para os pacotes começarem a fluir novamente; mas eu tenho notado esses problemas depois que eu mudei recentemente meu provedor para Sky, Uk e eles forneceram um roteador com o número do modelo, SR101
