Windows XP Home SP3 Formatting problem

I have a big problem (at least for me) wanting to format my computer which was then under Windows XP Home SP3 and there was a step backward: I boot to format the original installation CD (SP1 family), everything goes well and then when I want to connect to my livebox by wi-fi nothing happens. When I activate the wi-fi window does not appeared. Moreover, in network connections only the 1394 connection is present but no wireless network connection. In addition, I have the impression that the PC has "regressed" large icons at the opening sessions, no music or the ignition or extinction.

provide the exact model of the motherboard and the wireless card for us to help you.

In fact it is a laptop too, therefore, not want to look within is how to find the motherboard model and the wi-fi card please? This motherboard has been changed by the VAS of Medion after sending the 3rd and I had not formatted for this change (and they do not send me CD)

Previously I had already carried out successfully formatting. Nothing to install than XP.

If it is a SP1, it needs SATA drivers (if you have a dd of this type), but surely on the CD manufacturer. On a mobile phone brand, I do not know, but on a pc fixed, after formatting you must reinstall the chipset drivers (see cd for the motherboard) for the network card.
