Is your router set up for WEP or WPA (which is the security for the network)? If you are not sure, check 'Properties' for your network card on the Windows lapotop. If you set up the router and have admin access to it, you should be able to see in the Wireless settings if it is set for WEP. Either case, since you mention 10 password (not sure what you mean by from the bottom of the router), it is not really the WEP security (which will be 13 characters ASCII for 128bit, or a lot of hex digits in the range 0-F if it HEX). Assuming you can pick the network from Airport icon on top right, try 'None' for wireless security.
