    Hi Abhinav K Sahdev,
    if you are trying to connect using:
    Code:
    sudo wvdial
    then the problem may be wrong APN and/or username/password.

    Post here your /etc/wvdial.conf file and Country/Provider to check above data.

    Regards,
    George

    Init1 changed to ATZ and 'Stupid mode = Yes' added to skip 'prompt at login'.

    Hi vikaskumargdra, welcome to this forum!
    To get wvdial working you need 5 .deb files (download and install).
    If you have a working connection to the Ubuntu running pc, use System > Preferences > Synaptic to get it OR from terminal:
    Code:
    sudo apt-get install wvdial
    If you are offline, follow instructions
    It is better to use files made for your Ubuntu version and CPU architecture. If you have Ubuntu 9.04 running on 32 bit Intel get my zip file unzip it on desktop and double click on each .deb icon in the following manner:

    1. libxplc0.3.13
    2. libwvstreams4.4-base
    3. libwvstreams4.4-extras
    4. libuniconf4.4
    5. wvdial

    If you have any problem/question post it to follow up.

    Regards,
    George

    Exclamation Re: Problem with Reliance Netconnect LG LXU-800 USB Modem

    Thanks a lot George.Your method was excellent.It worked for me.Im posting this from ma Ubuntu!,but I've a little problem.
    I hv to add the line quiet splash usbserial.vendor=0x0eab usbserial.product=0x9357 at kernel editing every time I restart my computer otherwise when I dial wvdial it gives the following error:-

    --> WvDial: Internet dialer version 1.60
    --> Cannot open /dev/ttyUSB0: No such file or directory
    --> Cannot open /dev/ttyUSB0: No such file or directory
    --> Cannot open /dev/ttyUSB0: No such file or directory

    and if i've added the line at restart,it is working great.
    can u tell me how to fix this.
    Also if u r on yahoo messenger or g talk,pls give me ur id.I have a lot of questions want to share.
    Thanks

    Re: Problem with Reliance Netconnect LG LXU-800 USB Modem

    Hi vikaskumargdra,
    you must use this method to connect, then you are going to do a full (and long!) update which will make the usbserial a driver. From this point the command will become:
    Code:
    sudo modprobe usbserial vendor=0x0eab product=0x9357
    Later you can try to add a udev rule (automatic 'run' of above command when the modem is attached) or better try to make Network Manager useable (more difficult, more internet searching).

    >>> udev rule creation:
    Code:
    gksudo gedit /etc/udev/rules.d/90-newmodem.rules
    and copy into that file the following:
    Code:
    ACTION!="add", GOTO="modemEnd"
    #
    SUBSYSTEM=="usb", SYSFS{idProduct}=="9357", SYSFS{idVendor}=="0eab", GOTO="newModem"
    #
    LABEL="newModem"
    RUN+="/sbin/modprobe usbserial vendor=0x0eab product=0x9357, MODE="660", GROUP="dialout"
    #
    LABEL="modemEnd"
    Save and Exit from gedit. After reboot it must be OK.

    Regards,
    George

    P.S. I am not using any 'online messenger'

    The problem is still there.
    here is the output:

    vikas@Searching:~$ sudo wvdial
    [sudo] password for vikas:
    --> WvDial: Internet dialer version 1.60
    --> Cannot open /dev/ttyUSB0: No such file or directory
    --> Cannot open /dev/ttyUSB0: No such file or directory
    --> Cannot open /dev/ttyUSB0: No such file or directory
    vikas@Searching:~$ sudo modprobe usbserial vendor=0x0eab product=0x9357
    FATAL: Module usbserial not found.

    Have I do a full OS update???

    Yes, you did not update the system. Try:
    Code:
    uname -a
    this will show you the kernel version which is the initial (old) for 9.04 which has the usbserial encapsulated. You must use the 'edit grub' way to gain access to the modem, connect to internet, fully update from System > Administration > Update manager (long enough!) or from terminal:
    Code:
    sudo apt-get update && sudo apt-get dist-upgrade
    After rebooting the new kernel version (from 2.6.28-13-generic and later) you can use 'modprobe usbserial' as a command.

    Regards,
    George
