Sono un felice utente di Ubuntu da ormai un mese su un desktop e ieri ho deciso di installarlo anche sul portatile Toshiba Satellite A210-150. Ho intallato la versione a 64 bit.
Il problema è che non funziona la connessione, nè per gli aggiornamenti, nè per la navigazione (Firefox).
Il portatile è collegato ad un HAG fastweb ADSL con cavo ethernet. Sul computer fisso non ho dovuto configurare niente, funzionava tutto in automatico.
Ho cercato la soluzione a questo problema, ma non ho trovato niente di utile.
Vi posto qualche log:

Sorry, I scanned 2 interfaces, but the Access │

Interface has MTU of 0 -- should be 892242408. You may have serious connection problems.
Cosa mi consigliate di fare?
Grazie in anticipo per le risposte.
