Internet Connection Problems (XP)

Well, I had to re-install Windows XP on my old computer (I'll save you the details), and know im trying to connect it to the internet, but I'm stuck. The way i have it set up is, I have a router that connects wirelessly to this desktop and my laptop, and an ethernet cord is going from my router into my old computer. Yet, I do not know how to set it up anymore. I have a Software installation disk from Bell (Canadian ISP) and when i try to install the software, it says I have no network adapter. So, do you guys know how I can install drivers for my network card, even if I dont have the CD? Or is there any other way to connect my computer to the internet?

Once the motherboard driver is intalled xp should detect your network card and install it. From there you put in your

internet provider cd in and your network ip. Most times it is the problem.

i dont think u installed Ethernet drivers on the old computer5ssj

where do I install these ethernet drivers? from a given disc? if not should i download it from the interent and transfer via USB and install?
