It will help people to help you if you are quite specific about your hardware, and also about the steps you have taken to try to deal with the problem already. I could assume that when you say "my card" that you are talking about a wireless card, but I could be mistaken. Have you tried going into System >> Preferences >> Network Connections, and looking at what is listed there? You may need to "add" the appropriate connection. A few times with earlier distros, I have had to "tell" Ubuntu that it was connected to a LAN with a wired connection. If you do need any Linux drivers that have not been loaded, there is a good chance that they are on the installation disk.
If you open a terminal window (Applications >> Accessories >> Terminal), and type: lspci |less (Then hit the Enter key), it should give a list of the cards in your computer. (if output is longer than 1 screen, page-down with the space bar). This is why it is important that you know what hardware you have; then you will know if the system recognizes it. Some hardware is not supported by Linux, although the list seems to get shorter every day. If you have the original manual for the computer, this may have many of the hardware specifications.
It will also help anybody who is trying to help you. "I can't get on the Internet" is not as useful as (for instance) "I have a Dell C11000X laptop with a Martian Z-6000 wireless card, running Ubuntu 10.04 with a Gnome desktop. When I open Firefox, I get no internet connection, with the message: 'Firefox cannot find the server at www.blahblahblah.net'".
So, do your homework on what hardware you have, report back, and be specific about your problem, OK? Even if I don't see it, it will help the next person who is trying to help. Much luck!
