Come posso accedere alla banda larga mobile dalla mia penna USB?

4

Non riesco ad accedere a Internet utilizzando il mio modem USB sul mio portatile. Mentre posso accedere a Internet dal mio PC. Entrambi eseguono Ubuntu 12.04.

Che cosa posso fare per rilevare il problema?

Qui il risultato di lsusb

I modem ZTE 3G a volte vengono come "dual media", fungono da CD all'accensione.

Ecco cosa funziona per me: (meglio aprire due finestre di terminale)

In un tipo di terminale tailf /var/log/syslog per guardare cosa succede
nell'altro tipo eject sr1 (che dovrebbe disabilitare la modalità CD e far sì che il sistema lo riconosca come modem).

Dopo un po 'di tempo (vedo quando l'attività in syslog rallenta di nuovo), posso usare network-manager per connettermi al mio provider 3G.
