I just installed Ubuntu. How can I make an internet connection?
When I start Firefox, the response is
Server not found.
I have a BSNL broadband connection in India via my telephone line and a ADSL modem.
Bharat Sanchar Nigam Ltd have a Customer Care service on:
BSNL Broadband Helpline *Number '1504'
Are you using the pre-paid subscription? Did you provide your own modem? What type of modem do you have? Have you enabled networking from the network icon (top right-the bar graph icon)?
The BSNL helpline and staff are generally familiar with MS Windows and may not be too helpful but if they are, it will be a pleasant surprise.
I'm assuming that: the modem is an ADSL router; you are dual booting with MS Windows; and you have no problem connecting via MS Windows.
That should do it. If you are not on an unlimited plan, you may not want to connect "automatically".
Open a Terminal (Ctrl+Alt+T), type
Then a window will appear with a bar--it's checking your Internet connection.
If your connection is working properly it will ask you some questions. Press Enter on every question for "yes." In between it will ask your connection's username and password.
Once you've done this, every time you boot your Ubuntu system it will automatically connect to the Internet.
