problem connecting with usb 3g modem

[Smarty_T2]

Hello Everyone
I am using Ubuntu 10.10. I have Micromax MMX 310G USB Modem with a bsnl 3G SIM Card. When I plug-in my device in my PC and open network connections, I tried creating a new mobile broadband connection and my device is not shown there.

Now, when i opened "computer", i found two things there A "Floppy Drive" and a "Modem". "Modem" is of unreadable format(though it works on windows and is the modem installation disc) while floppy drive must be the memory card reader thats built in the device.
I right clicked on the modem->open and nothing happens. But after doing that, when i go to network connections again and create a connection, i find my device there. I selected that device and created a cellone connection with "north india" as my plan But it just keeps on trying to connect for 5-10 min and then says disconnected. It is just not able to connect.

Is anybody having any idea about how to connnect through that modem. If you are using it, what did you do to make it work on your system.

Thank You

Hi
check to see if recognized by Network Manager

check with nm-tool from the terminal

nm-tool

if see a message like

- Device: ttyUSB3 --------------------------------------------------------------
Type: Mobile Broadband (GSM)
Driver: option
State: disconnected
Default: no

Capabilities:

then it has been recognized , the tty* may be different,leaving only the correct data been entered.

if nothing shows
first try and eject the device , don't do this from opening "computer" if the only option is safely remove;

open up the Disk Utility from System/Administration/Disk Utilty

click on the device look at the options in right hand pane select eject

note any change with the nm-tool

can also monitor any changes of the device id's with the lsusb command
use this before the eject command , then after the eject command

lsusb

see what happens , also post the results of the two lsusb commands

@kareempharmacist: I have already purchased this modem and cannot buy a new one now.

Got no tty stuff...
Then i opened the disk utility. There were 2 devices there, a floppy drive and a modem disk. The only options for the modem were to safely remove and other i dont remember and that other one was also the only option for floppy drive. I tried safley remove for modem and got an error.
Then again i ran the nm-tool command at the terminal and got this...

NetworkManager Tool

Got this tty this time and there was option to connect in the network connections. I clicked on it and waited for 12 minutes and it didnt connect so i just plugged out my device.

And i didn't understood the use of lsusb command...

Thank you

hi

lsusb ' gives the ids, and type of device,

use from the terminal

lsusb

from this info it will list ID's of the device + type or product

can also post the results of

ls -al /dev/serial/by-id

this is is now important as this will indicate if the correct ttyport is been identified by the
network manager

also need to Know which version of Ubuntu been used
ie ubuntu 9.04 , 9.10, 10.04 etc

Hello All,

I am visiting this thread after sometime. I am having the same problem. I am using Ubuntu 10.10. I have Micromax MMX 310G USB Modem with a bsnl 3G SIM Card. I created a new mobile broadband connection. When I try to plug-in the device, it is not showing a new network connection.
I downloaded Sakis 3G utility. Unfortunately, it did not work as well. It is failing after when "switching to the modem". I was getting the error message, "Failed to Connect".
Then I looked into 'more options'. There when I click on 'Only switch modem' option, it returns successfully with the message "Modem switched to 1c9e:f000". But when I click on 'Only setup modem (Switch + Load Module + Setup tty)', it fails with the message "Failed to setup modem".

So can anyone help me or give me some advice?

Thanks
Sathya
