Vista - XP Downgrade Problems

So i downloaded my Compaq Presario F756NR Notebook from Vista-32bit tom XP-32 using a copy of y friend's XP installation disk and VistaBoot. I got XP to install smoothly but an error occurred along the way. It said that it couldn't install driver.cav (or something like that) but i pressed ESC to skip it. Anyway, XP is working fine and is much faster than Vista but i can't get the Network Drivers installed and when on a wired connection, it doeskin know that there is an internet connection. I've tried searching Google many times but i cant find any drivers that do a clean Network and Wi-Fi install Can someone please point me in the right direction? Thanks
