You do not need the installation CD to use the router. Check this link to download the user manual and quick install manual. As well you can download an updated firmware for your router along with installation instructions.
Good Luck.

Are you trying to set up router ?
You can set up your router manually, without the CD.
Make sure that your computer is able to go online directly through the modem.
If your computer is able to go online through the modem, that means the modem is working fine.
You will need to connect the computer to the router and the modem to the router.
open the set up page of the router and change the settings of the router according to the ISP.

Belkin does not have the CD software available to download from the site. However, these are normally used for "quick configuration" and are not needed in the long run. I found the manual for this router online. It will have instructions on configuring the router.

i want install a router

Correct model, Belkin discontinued production as it was a very bad product (blame the firmware). I know it is, I own one.

You can manually install it even without the setup CD , if you still have teh userguide you can find the steps there how to manually isntall it if you're having problem using the manual better call belkin support to help you manually setup that.

Hope that helps...........
