Leonidas:

Have you received help or been successful yet? Typically you do NOT need to load router software into each computer. It just needs to be loaded in the main one connected to the internet and the router. When you start up a laptop, just go to the Control Panel or other icon and click on "View Available Wireless Networks." When you see your network name, click on it, click "Connect" and enter your established password. It should connect.

LMK if it works.
