Non ho provato comunque questa notte l'avevo lasciato acceso e alla mattina ho notato che il mulo non scaricava nulla e aveva le freccette arancio.L'ho chiuso e ho provato con thunderbird e non mi scaricava la posta e anche chrome non si collegava a nessuna pagina web.
Per ripristinare ho riavviato.
