Your new router will have a disc with it with an install program - or you can do it manually if you know what to do. You have to tell the router your internet log-on details - it connects to the dsl connection. The software will guide you through the connection from your PC to the router (usually by network cable and probably supplied with the router) and it will give you the choice of WEP/WPA security and allow you to assign a key/passcode. Yes there is an admin mode to contact the router from your PC.
