Apple - Time Capsule

This wonderful little treasure, the Apple Time Capsule, came to live at our house this week.  We are not using him to his full potential yet, as none of our Macs have Leopard installed yet.  But so far, so good, with wireless backup working from two Macs and two PCs at varying spots in the 4,100 square foot home.  The WiFi base station capability which would enable us to use this as a wireless router is not functioning properly, unfortunately, but the ease of the wireless backup has been a blessing.  If anyone has tips for configuring it as a router, I’d love to hear from you.  We’ve followed the instructions and can’t seem to get it functioning without crashing our cable connection.
