Can't connect to internet with networking

I just installed XP on my new Toshiba laptop which previously had Vista. I found the XP on some site which was a custom-made version. It works well, however, I am unable to connect to the internet via my host PC. Ihave tried all the settings and have just about given up. Also there is no sound because in Device Manager, it says no audio drivers are installed.

Right now I am mainly concerned about connecting to the internet. Do you think I should uninstall this XP and go back to Vista? I HATE VISTA!! This XP is so fast not like the Vista hog. Please help!!
