Most of the data cards available in the market are designed to work on windows and mac computers. Few have drivers (software) to work on GNU/Linux too! However for the data cards that do not have GNU/Linux drivers, here is the most generic and simple solution..
1. Connect the data card to the USB port.
2. Open the 'Terminal' (Application → Accessories → Terminal)
3. Two additional software are required for this activity. So use internet (may be wifi or cable) to download these software packages. In the terminal window, at the $ sign, type sudo apt-get install wvdial and when prompted for a password, type in your login password (you will not see a thing on the screen, don't worry just key in your password)
4. The next software package that we have to install is call usb-modeswitch. This package is very important because most of the datacards when plugged in acts like storage devices and not datacards and this package switches the devices' mode from storage device to a datacard. You can download this package from http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-1.2.0.tar.bz2 and you'll need another file which can be downloaded from here http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-data-20111023.tar.bz2. A supporting package called libusb is required too. This can be downloaded by typing sudo apt-get install libusb at the $ symbol in the terminal.
5. The two files downloaded needs to be unzipped (uncompressed). If you are not sure of where the files are, check your Downloads folder under the home folder. Right-click on the downloaded files and select extract here. Once this is done, go back to the terminal and type the following commands
cd ~/Downloads/usb-modeswitch-1.2.0
sudo make install (you'll have to enter your login password after this)
cd ~/Downloads/usb-modeswitch-data-20111023
sudo make install
sudo apt-get install libusb-dev
6. Now we need to configure wvdial. In the terminal at the $ symbol type sudo gedit /etc/wvdial.conf. This will open a text editor which might have some text in it. Replace the text with the following[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Username = <type your reliance number here> or internet (if it is a tata photon datacard)
Password = <type your reliance number here> or internet (if it is a tata photon datacard)
Phone = #777
Stupid Mode = 1
7. Once this is done, at the $ type sudo wvdial to connect to the internet
–> WvDial: Internet dialer version 1.60
–> Cannot get information for serial port.
–> Initializing modem.
–> Sending: ATZ
ATZ
OK
–> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
OK
–> Modem initialized.
–> Sending: ATDT#777
–> Waiting for carrier.
ATDT#777
CONNECT
–> Carrier detected. Starting PPP immediately.
–> Starting pppd at Thu Nov 5 15:45:26 2009
–> Pid of pppd: 3205
–> Using interface ppp0
–> pppd: 0$P
–> pppd: 0$P
–> pppd: 0$P
–> pppd: 0$P
–> pppd: 0$P
–> local IP address 115.184.194.33
–> pppd: 0$P
–> remote IP address 220.224.141.145
–> pppd: 0$P
–> primary DNS address 202.138.103.100
–> pppd: 0$P
–> secondary DNS address 202.138.96.2
–> pppd: 0$P
You are now connected to the internet
8. You can start browsing now and remember not to close the terminal window. To disconnect you'll have to press Ctrl C. Back to Top

Basic troubleshooting In school computer LAB
* The Computer Won’t Start A computer that suddenly shuts off or has difficulty starting up could have a failing power supply. Check that the computer is plugged into the power point properly and, if that doesn’t work, test the power point with another working device to confirm whether or not there is adequate power.
* The Screen is Blank If the computer is on but the screen is blank, there may be an issue with the connection between the computer and the screen. First, check to see if the monitor is plugged into a power point and that the connection between the monitor and computer hard drive is secure. If the problem is on a laptop, then you may need to get a professional to fix it as some of the internal wires may be worn.
* Abnormally Functioning Operating System or Software If the operating system or other software is either unresponsive or is acting up, then try restarting your computer.
* Ubuntu Won’t Boot If you are having troubles booting Ubuntu, then you may have to reinstall it with the Ubuntu DVD.
* The Screen is Frozen When you computer freezes, you may have no other option than to reboot and risk losing any unsaved work. Freezes can be a sign of insufficient ram, registry conflicts, corrupt or missing files, or spyware. Press and hold the power button until the computer turns off, then restart it and get to work cleaning up the system so that it doesn’t freeze again.
* Computer is Slow If your computer is slower than normal, you can often fix the problem simply by cleaning the hard disk of unwanted files.
* Strange Noises A lot of noise coming from your computer is generally a sign of either hardware malfunction or a noisy fan. Hard drives often make noise just before they fail, so you may want to back up information just in case, and fans are very easy to replace.
* Overheating If a computer case lacks a sufficient cooling system, then the computer’s components may start to generate excess heat during operation. To avoid your computer burning itself out, turn it off and let it rest if it’s getting hot. Additionally, you can check the fan to make sure it’s working properly.
* Dropped Internet Connections Dropped Internet connections can be very frustrating. Often the problem is simple and may be caused by a bad cable or phone line, which is easy to fix.
* Reboot your computer. Turn your computer off, let it sit for two minutes, and reboot it. Sometimes one command of the hundreds a computer executes every second can cause corrupted memory or other temporary unexplainable problems. Rebooting will clear out all the gremlins and gives everything a fresh-start.
