    Question Pantech USB broadband modem and 11.10

    I've got a Pantech 290 broadband modem with Verizon. It works fine (with the VZManager software) on my Windows laptop, but I can't seem to get it to work with my Kubuntu Onieric laptop. It seems to recognize the modem (as /tty/ACM0) when I plug it in. Network Manager seems to recognize that it's there, but can't make a connection with it. I've seen reports that this "just works" in 11.04, but apparently not in 11.10. Any suggestions? Is there any way to get network manager to spit out debugging info about what it's trying to do?

    Re: Pantech USB broadband modem and 11.10

    the problem may lay with modem-manager

    can download mm-test.py from here
    Code:
    wget http://cgit.freedesktop.org/ModemManager/ModemManager/plain/test/mm-test.py
    it should be in your home folder.

    or paste in the browser
    Code:
    http://cgit.freedesktop.org/ModemManager/ModemManager/plain/test/mm-test.py
    save the page to the home directory ensure named "mm-test.py".

    run it as root
    Code:
    sudo su
    python `pwd`/mm-test.py
    can also try
    Code:
    killall modem-manager
    if modem-manager hanging onto the device
    wait a while for modem-manager to re init and prob the device , then do the test again

    Re: Pantech USB broadband modem and 11.10

    OK, I downloaded the script and ran it. Got this:
    Code:
    CDMA modem
    Driver: 'cdc_acm'
    Modem device: '/sys/devices/pci0000:00/0000:00:1a.7/usb1/1-3'
    Data device: 'ttyACM0'
    Vendor:  PCD
    Model:   UML290VW
    Version: L0290VWB522F.242  1  [May 12 2011 13:21:52]
    
    ESN: <private>
    1x State:   registered (roaming unknown)
    EVDO State: registered (roaming unknown)
    Signal quality: 48
    Class: Unknown
    Band:  Z
    SID:   78
    When I look at it in Network Manager,
    it looks like this (Note - I did check "enable mobile broadband):
    Code:
    Type: Mobile Broadband
    Connection State: not enabled
    IP Address: no address
    Connection Speed: unknown
    System Name: ttyACM0
    MAC Address: 
    Driver: cdc_acm
    Operator: 
    Signal Quality: 0%
    Access Technology: unknown/unknown
    When I look at the configuration for the wireless connection in Network Manager, it's set to
    Code:
    Number: #777
    Username: <mynumber>@vzw4g.com
    Password: vzw
    Any other suggestions?

    Looks like it's right there at the top, but I don't know how to decode the I: lines.

    Also, I went into /etc/NetworkManager/NetworkManager.conf and added a logging stanza to log debug info about mobile broadband. When I tried to connect with the modem I got this in the log:
    Code:
    Nov 17 13:56:29 Ultor modem-manager[21432]: <info>  Modem /org/freedesktop/ModemManager/Modems/0: state changed (registered -> connecting)

    Re: Pantech USB broadband modem and 11.10

    no sure if the parts of the diver are binding to the device correctly
    although the correct driver has loaded for the device
    can be seen from

    Code:
    grep -i v106cp3718 /lib/modules/`uname -r`/modules.alias
    so need more info
    Code:
    grep  v106cp3718 /sys/bus/usb/devices/*/modalias

    Re: Pantech USB broadband modem and 11.10

    First, thanks for the help so far!

    Here's what I get
    Code:
    mike@Ultor:~$ grep -i v106cp3718 /lib/modules/`uname -r`/modules.alias
    alias usb:v106Cp3718d*dc*dsc*dp*icFFiscFFipFF* qcaux
    and
    Code:
    mike@Ultor:~$ grep  v106cp3718 /sys/bus/usb/devices/*/modalias
    mike@Ultor:~$

    Re: Pantech USB broadband modem and 11.10

    hi
    think made common typo in the above notice the lower and upper case
    the usb ids module(modalias) is different to whats logged in the files
    Code:
    grep  v106Cp3718 /sys/bus/usb/devices/*/modalias

    Network Manager is indicating fail at " if0"
    Nov 17 13:56:29 Ultor NetworkManager[21434]: nm_system_iface_flush_routes: assertion `ifindex > 0' failed
    Nov 17 13:56:29 Ultor NetworkManager[21434]: nm_system_iface_flush_addresses: assertion `ifindex > 0' failed
    but mm indicates a dial up connection has been made
    Nov 17 13:56:29 Ultor modem-manager<info> Modem /org/freedesktop/ModemManager/Modems/0: state changed (registered -> connecting)
    Nov 17 13:56:29 Ultor modem-manager[21432]: <info> Modem /org/freedesktop/ModemManager/Modems/0: state changed (connecting -> registered)

    so not sure where what the problem is

    the message from the device "
    No carrier"

    is pppd failing to negotiated the connection or is the port closing before before the pppd is starting, can look further into the log files
    have done a post about logging mm and nm at

    How To : Mobile Broadband Connections [ Ubuntu 11.04 : 10.10 : 10.04 : 9.10]

    at the end of the thread there is a script which may shed some light about the device can use the script with arg "tty" the out put will show the status line of the device + responce to at command ; then will list all of what udev sees about the device

    if trying some of the testing from 2 terminals then don't forget to use ATDT#777

    although mm is seeing the device it is picking up the first port as indicated by mm ACM0
    so can see if the device is in the dev
    Code:
    ls -al /dev/serial/by-id
    Code:
    ls /dev/ttyACM*
    also try can try ppp directly or wvdial see what happens

    Re: Pantech USB broadband modem and 11.10

    had to some thinking about this mm-test.py , first time thought about taking it for a ride

    to get this thing to work need' mm-test-pppd-plugin.so

    got it from
    http://pkgs.org/download/ModemManager
    its and rpm package (openSUSE factory)
    make sure its the latest source package and ensure it lists the mm-test-pppd-plugin.so and correct 586(32 bit) or amd64 bit

    just upack and find the ' mm-test-pppd-plugin.so
    can use gksu nautilus on Ubuntu : don't know about kubuntu
    or as root sudo su , cp it to
    /usr/lib/pppd/2.4.5/
    then from the terminal
    Code:
    sudo su
    python /home/<user>/mm-test.py --no-scan  --connect --ip
