Network hardware problem!!!

Hi everyone. I just joined the dell community because i am having an issue about my dell laptop. My computer first ran windowx xp pro sp3. Then i installed opensuse. Now i want to reinstall indowx xp. The installation was successful. Suddenly i find out that i cannot connect to the internet. I think i am missing some network hardware. I tried to download some necessary hardware from dell website. My model is insiron 2200. Please tell me how to install ALL the needed network hardware so that i can go to the internet.Thanks :D
