i have a toshiba laptop that i have an always on internet connection and i need to get online with my vista ultimate Desktop machine, i have them hooked up via cross over cable but when i connect i only get limited connectivity and my internet gets lost on the xp machine. i know i am missing some steps but not too sure what ones? i share a house with others that are on the same cable modem as me through a gigabit n router. which is down in my landlords part of the house. i had it set up once to connect and the connection went down because the router was changed.
