help after reformatting....

I don't know if this is the right topic, but I figure I'll try here. I have a Dell Pc and Laptop. I never got an XP installation disc with my laptop since I bought it used. I reformatted my laptop yesterday using my dell cd that came with my pc... The process was successful, however my laptop no longer recognizes that it has a wireless card in it, and when I tried to connect the laptop to my modem via ethernet, it still wouldn't connect... How can I fix this???

 

Try downloading the drivers from Dell. Look for the model # you have.

 

The model # of the laptop or the wireless card? If I need the model for the wireless card, how do I find that?
