I lost my cd to install how do i go by installing

you said that you are to connect the new laptop to the router.
Do you have any other computer already working through the router ?
If your other computers are working through the router then your router already set up and you don't need to run the CD. all you need to do is connect to the wireless network.
If this is the only one computer in your network and you are trying to install the router then you can do it manually also without CD.
