A small clarification

[cannon_dt]

Hi All,
I am a newbie to the wonderful world of Linux and Ubuntu.
I just burnt a live CD of Ubuntu 8.10 and I am enjoying my stay thus far. I am soon going to become a full fledged user of Ubuntu and become an ardent OSS member !
I have one question. When dabbling with the live CD, I tested my internet. In fact I did nothing, after the live CD came up, I just opened firefox, browsed, downloaded with no problems.
Can I expect the same to happen once I install ubuntu? Or do I need to configure et al?
I am in India and I have a BSNL broad band connection. I used a UT300R2U modem that plugs into a router (I use a router to mainly stream wirelessly to my other device which is a PlayStation 3).
So I need this configuration intact (how to stream wirelessly in Ubuntu is my next problem but I am sure that can be solved).
So can someone tell me what I need to worry about with respect to internet and if the live CD does well with internet does it mean that post-installing ubuntu I would have no problems? All heads up and help would be most appreciated.

Thanks,
Cannon

after installing, it will be running the same kernel, so everything will be the same. (unless some updates don't f#ck up things, which happens from time to time)
