i have never done this before. i have a laptop computer running windows 7 ultimate that i have recently taken to my brothers house and used his internet to download some files. i have no internet at my house and i need to transfer these files to my desktop computer at home. i do not have an ethernet crossover cable but i do have a 4 port router at my house. i was wondering if it was possible for me to plug the laptop and desktop direct into the router and file share through the router with no modem hooked up.
