Purtroppo dopo aver istallato il nuovo ubuntu, è impossibile collegarsi a internet. Pur trovando la scheda di rete, la stessa sembra inutilizzabile (con la versione 10.4) il tutto funzionava.

seguito le istruzioni, ma nulla da fare.

sono comandi che servono a far capire la tua situazione, dovresti farci  vedere le risposte.

Grazie per la risposta.
Ho provato, ma il risultato è il seguente:

Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces

                       

quando dai
cosa esce?

non esce nulla

prova
se non va la connessione

se ho capito bene, tu adesso ti stai connettendo con il wireless, che ti funziona,    quando provi

questi comandi, la connessione wireless è spenta?

a cosa ti colleghi?    il dispositivo a cui ti colleghi ha il dhcp abilitato?   la connessione che hai, prende i parametri in automatico?

il driver è caricato, eth0, che è  l'interfaccia da configurare è presente, non ci dovrebbero essere problemi.

prova semmai a fare una connessione nuova    (clicca con il destro sulla icona della connessione

vai su modifica connessioni   poi  vai su via cavo e aggiungi.)

Ho aggiunto nuova connessione e adesso funziona.
Grazie per l'aiuto.
