How To Connect Tata Photon Whiz/Plug2Surf With Ubuntu Linux
By on April 16th, 2010

Tata Indicom has changed the face of wireless broadband in India. With its comparatively cheap unlimited offer, it is currently the best buy.

Tata Indicom offers unlimited surfing + download at Rs.800 per month. The offer is valid for Tata Photon Whiz. Although it operates at a compromised speed, it provides the advantage of unlimited surfing.

Tata Indicom Whiz has a dialer for Windows. However, many complain that there is no Tata Indicom dialer for Linux.

Well, there is no dialer because Linux has a dialer of its own which does the job. Follow these steps to setup your Photon Whiz with the “wvdial” dialer.

  1. Install “wvdial” if you do not have it already. To install wvdial, use the command:
    sudo apt-get install wvdial
  2. Next, plug in your Tata Indicom USB Modem.
  3. Now, create a dialer for your modem with the command:
    sudo wvdialconf /etc/wvdial.conf

    This creates the appropriate dialer configuration for your modem. Remember to keep the modem plugged in while running this command.

  4. Edit the wvdial.conf file by issuing
    sudo vi /etc/wvdial.conf
  5. Your wvdial.conf file opens on issuing the above command. It should look like this :
    [Dialer Defaults]
    Init1 = ATZ
    Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
    Init3 = AT+CRM=1
    Stupid Mode = 1
    Modem Type = Analog Modem
    Phone = 0
    ISDN = 0
    Password = <password>
    New PPPD = <username>
    Username = internet
    Modem = /dev/ttyUSB0
    Baud = 9600
  6. Now you have to edit the file.  Put “internet” in place of <username> and <password>. Do not change any other auto-generated entry. Place the appropriate phone number in place of 0. It is #777 for Tata Indocom.

That should complete setting up your dialer. Now, to dial a connection, simply execute

sudo wvdial

in a terminal window. Enjoy.

[ In case it still does not work, add the lines:

Init3 = AT+CRM=1

and

Stupid Mode = 1

Stupid mode allows the connection to dial through a firewall and Init3 = AT+CRM=1 prevents frequent disconnections.
