I answer myself. Googling I've found this GSM/3G card can be used as modem or either as ethernet card.
You can see more information in http://www.thinkwiki.org/wiki/Ericsson_F3507g_Mobile_Broadband_Module Then, now I can see the card as a modem again. I'm not able to connect yet, but is for other problem. ** Changed in: network-manager-applet (Ubuntu) Status: New => Invalid -- Network manager detect mobile broadband modem as wired lan https://bugs.launchpad.net/bugs/488332 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
