Disable the "Carrier Check" option and it should work fine.

Hi list, Please enlighten me if you have any experience with using the Tata Indicom USB Modem under the Plug 2 Surf scheme. I have recently taken their subscription and facing problems using it with Kubuntu 7.10 It works fine in windoze, but fails to get any data transfer in Linux. I tried connecting using wvdial and also using KPPP.
The following is a copy of what i get at the terminal on running wvdialconf:
$ sudo wvdialconf /etc/wvdial.conf Editing `/etc/wvdial.conf'.
Scanning your serial ports for a modem.

//////// It appears that it successfully detected a USB modem and created a wvdial.conf file accordingly.
But on trying to dial using "sudo wvdial", i get the following on the terminal:
kamal@kMax:~$ sudo wvdial WvDial<*1>: WvDial: Internet dialer version 1.56 WvModem<*1>: Cannot get information for serial port. WvDial<*1>: Initializing modem.

WvDial Modem<*1>: ATDT#777 WvDial Modem<*1>: CONNECT WvDial<*1>: Carrier detected. Waiting for prompt.
... and so on and so forth.. it keeps repeating connection attempts and gives the same error "WvDial<Err>: Connected, but carrier signal lost! Retrying..."
I have used wvdial for MTNL Garuda's USB modem on the same installation and it was working fine back then. Also, there was an existent wvdial.conf file with those old settings for MTNL Garuda connection until i executed "wvdialconf" again for the tata indicom USB modem. [* wvdial gave the same problem even with Ubuntu 7.04 installed on the same machine.]
While when i tried connecting with KPPP on Kubuntu 7.10, it did succeed in connecting, that is, it showed me that its connected and the USB modem's indicator too indicated a connection. But i still could not surf the net (or ping any websites)
Am i missing out something while configuring the connection. Could this be an issue with the DNS? The same modem is working fine for windoze on the same machine.
Any help or your experiences in this regard are greatly appreciated. Thanks.
