Gateway M275 Re-loaded OS windows xp missings drivers

I wanted to give my Laptop a fresh start and formated my hardrive and loaded my OS. During the install windows asked me for a I386/TablePC CD which I do not have. I told it to skip and OS completed the install. Some of my functions will not work including my 10/base T port and neither my wireless function so I can not get on the Net? Any Help.
