We're not mind readers. You didn't include a single bit of info about your computer or your network controller. To be able to find drivers, you (or we) need to know the exact make/model of the controller.
And since you just reinstalled XP, there are numerous other drivers you should install as well. Windows will install generic drivers (if it has them) but to get full use of your hardware, you need to install the 'real' drivers. You'll need them for the motherboard chipset, video, sound & possibly other devices.
