I have having alot of wireless disconnects and i cant get the network between all 3 pc to stay connected.Please help!!!!!

!! The router and laptop is across the street at my friends house. They allow me to connect to their network for online use. The belkin router has a range of 400ft and my belkin mimo usb adapter has a range of 1000ft. I am not using the belkin software only the windows xp home software. I would like to use my own ip addresses. my pc has a 1.4ghz processor,512
