how to install and configure ADSL Modem

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

please anyone help me

VP Gautham,

i will try to help you,
can you please do this:

Shut down the PC,
connect the USB-ADSL-modem,
first put the modem on, wait for 2 minutes
then power ON the PC.

Log in to Ubuntu.
.1. Do you see a new icon on your Desktop (the modem?!?)

.2. IF there is a network-icon in your Application-bar,
    THEN put the mouse-cursor above that icon; left-click (Manually Network Configuration);
    ELSE (there is no network icon) select the menu-path
   <Applications>... , <System>..., <Network>...
(Perhaps the path is somewhat different in the Ubuntu-version you have...)

There will pop up a window (named probably: NetworkConfiguration / NetworkSettings)

Please describe what you see here,
i assume something like:
   [ Wired Connection
   [ USB-Connection
   [ Point-to-Point Connection

With your answer we can continue the search for a solution.

Sir,

Thank you for your response

but i did not see any icon on desktop
in System-->Adminstration-->Network i saw

   [Wired Connection(pan0)
   [Wired Connection(eth0)
   [Point-to-Point Connection

What i have to do next?
pls help me menting

VP Gautham,

In Windows, you can find the settings of your USB-modem; write them down...
Start Ubuntu, go to the menu
<System>,... <Administration>,... <Network>,...
In that screen you can <Unlock> the situation using your password.

Select the line Wired_Connection(pan0), and then <Properties>
Now fill in the blanks using the information you wrote down.

Somewhere in the menu you can choose to set the default network connection to PAN0; i assume that this was set to ETH0; so your PC was trying to connect to the internet using a wired-connection.

Please let us know if this was the problem...

Sir,
I didn't find that Wired_Connection(pan0). i got a cable to connect the router through lan card. can you help me to connect it through lan card.

Please help me

VP Gautham,

Excuse i did not answered sooner... and
sorry if i did not understand you correct the first time...
To connect the PC with a wired connection, act thus:

1. shut down the PC
2. connect the PC with the router
3. check that the router is ON
4. boot the PC ; on the router the connection-light with the corresponding port is going ON
5. select <System>,... <Administration>,... <Network>,...
   in that screen choose the <Unlock>-button and enter your password
6. from the connections shown there, select the correct one (in this case the ETH0...)
7. press the <Properties>-button and fill in the blanks there
   Often the setting DHCP is working, so try that one first.
If you have a paper saying what settings to use, you can set the type connection to "Static IP-address" and fill in the blanks conform the paper.

Can you reach the InterNet now ?!?

'pon dsl-provider'

and disconnect by entering

'poff dsl-provider'

pls help me

VP Gautham,

there is a trick to do this:
you are going to create 2 unix-scripts: one for connecting and one for disconnecting.

Start a terminal window (i assume you know how to do this...)
enter these commands (all between brackets is my comment and explanation, so do not enter this...)

   cd ~/Desktop (the prompt will be Name@PC:~/Desktop$ )

   /usr/bin/nano ./OpenInternet.sh (is Dot-Slash-OpenINTernet-dot-sh)
            (you are working in the editor NANO ...)
            (the editor-commands are below)
            (Ctrl-o is SAVE)
            (Ctrl-x is QUIT/exit)
            (now enter this text carefully, and save it)

   #!/bin/sh
   # script used to start and open the internet connection

   /usr/bin/sudo /usr/sbin/pppoeconf

   /usr/bin/pon dsl-provider

            (Ctrl-o and Ctrl-X will save it and exit NANO)
            (your prompt is back to Name@PC:~/Desktop$ )
            (now you must be able to run the script)

   /bin/chmod u+x ./OpenInternet.sh

            (the same must be done for disconnecting)
            (so now without my comment:)

   /usr/bin/nano ./CloseInternet.sh

   #!/bin/sh
   # script used to start and open the internet connection

   /usr/bin/poff dsl-provider

            (Ctrl-o and Ctrl-X will save it and exit NANO)
            (your prompt is back to Name@PC:~/Desktop$ )

On your desktop there are 2 new icons visible:
OpenInternet and CloseInternet; try them.

Sir,

 I tried it and two icons appeared.
Openinternet.sh And Closeinternet.sh
But when i double clicked on Closeinternet.sh a gedit window appeared and displayed what i entered in terminal

Openinternet.sh opened a dialougue box with options run in terminal and display . I clicked run in terminal but it opened the configuration window.

What is next?

Anyway thank you very much Sir

What to do

If you start a terminal, and enter the command:

   /bin/cat ~/Desktop/OpenInternet.sh

then this text must appear on your screen:

   #!/bin/sh
   # script used to start and open the internet connection

   /usr/bin/sudo /usr/sbin/pppoeconf

   /usr/bin/pon dsl-provider

and after this text the prompt again, something like Gautham@MyPc$
if you enter the command:

   /bin/cat ~/Desktop/CloseInternet.sh

then this text must appear on your screen:

   #!/bin/sh
   # script used to start and open the internet connection

   /usr/bin/poff dsl-provider

and after this text the prompt again, something like Gautham@MyPc$

Please can you verify this... Thank you.

The command (the second thing on the line is Minus-L)

   /bin/ls -l ~/Desktop/*Internet.sh

must give 2 lines like:

-rwxr-xr-x 1 Username Groupname Number 2009-06-27 .......

Please verify the third character on the line is an x, in -rwxr-...
Thank you for your answer.

Sir,

Thank you. My problem solved.

A line was missing. i copied it and paste

That solved my problem.

Thank you very much sir
