Ecco la cosa! Sono il giorno 5 senza connessione a Internet via cavo. Ho trascorso gli ultimi 4 giorni a cercare in tutti i forum e siti di domande e risposte, fino a quando non ho finalmente deciso di pubblicare questo, quindi ho fatto i compiti. Prima di portare il mio laptop in officina per guasti hardware, voglio prima verificare con voi.
Descrizione del problema: come dice la domanda, la mia connessione cablata ha smesso di funzionare improvvisamente dopo un aggiornamento. Sto usando Ubuntu 12.04 LTS. Network Manager afferma che le reti cablate sono disconnesse . Il wireless funziona perfettamente. Inoltre, non funziona anche su Windows 7, dice cavo scollegato. Ho provato il cavo su un altro computer e funziona perfettamente.
