    ubuntu 12.10 wwan modem sierra 7710 not detected

    Hallo All,

    could you please help me? I am trying to get the sierra LTE Module in an Fujitsu U776 running.

    with ubuntu 12.04, the modemmanager showed the device. but it was not possible to connect to the network.

    with ubuntu 12.10, the device doesn't even appear in the modemmanger indicator.

    lsubs says this:

    what can i do? Any ideas?

    Did you see the thread

    ?

    A lot of the hints provided there are relavant for you as well. You need to verify that the modem is online in full power mode (i.e. that rfkill isn't blocking it) and that the necessary drivers are loaded. Then you need to run modem-manager with debugging to see why it doesn't pick it up.

    Start with
    usb-devices
    /var/log/dmesg
    rfkill list
    minicom /dev/ttyUSB2 and a few AT commands:
    AT!GSTATUS?
    AT!PCINFO?

    This looks fine. I get the same error message, but that is only cosmetical. Someone needs to fix that script...

    I could be wrong, but I do not think those ACPI warnings are related to any of this at all.

    OK, so there is no laptop specific platform driver involved here at all. I guess wwan should work if wlan and bluetooth works.


    finally, i see there are some problems but i don't really understand what the problems are and how to solve it.

    thank you very much.
    Nothing of the above indicates any problem AFAICS. Maybe you are hitting a modemmanager bug which was recently fixed in the stable MM branches? See
    https://bugzilla.redhat.com/show_bug.cgi?id=835153

    (I have no idea where the Ubuntu packages are related to this, but I would expect this fix to be included in the latest stable releases).

    NetworkManager and/or ModemManager logs should show if this is the case.

    Re: ubuntu 12.10 wwan modem sierra 7710 not detected

    In the meantime, i went back to 12.04 due to lots of other problems. Finally, the device shows up in the network-manager applet. When trying to connect, that is what

    grep -i networkmanager /var/log/syslog

    Re: ubuntu 12.10 wwan modem sierra 7710 not detected

    Should be fixed with Ubbuntu 13.04. Alternatively update kernel to version 3.6.1 or newer as it has implemented qmi and lte fix, supposedly making the mc7710 work.
