I am not getting internet connection in my newly installed Debian. I'm getting connection from live CD. What should I do?

Why not provide some more information. This information is not enough to help you out. How do you connect to internet? DSL? Cable? Dial-up? Wireless?

I've wired broadband connection. It's detected during booting. Biut it also says that 'failed to bring up eth0'. In the system tray, the connection is shown OK.

You may need to compile drivers for it, run command: lspci -v and post the output.
You should be able to copy the output and paste it into an editor and save as a text file to transfer to an OS that has a connection to post it here.

This is the output
