Tell us more about the CD and connecting to the Internet...
Is it a Microsoft Windows CD to set up your router? If it is, you may need to set up the router manually yourself. That's not as hard as it sounds. If you Google the make and model of your router you will find out how to communicate with it through a browser. I have a Thomson 585 v7. I can communicate with it by putting in the address bar of the browser: http://192.168.1.254. This can vary from one router to another. I just add username and password and it works.
Alternatively you might find that your ISP (Internet Service Provider) gives instructions on their web page about manually connecting.
I need to use a CD to connect to the internet, and can't find any way to bring up the CD.
