I lost the disk that set up my belkin N wireless router. i need to download the information onto another computer.

Your wireless network must be secured
You will need to check the wireless settings of the router.
Is there any computer online using the router.
check the IP address on that computer.
If yes then you can open the router set up page on that computer.
router set up page is the page where you can check all the router settings.
Click Here for more information about the routers and network

Please provide more detail information as to your issue.
there is not enough here to give a complete solution to your issue.

If you are having a issue with the CD then you will have to download the information directly from the site via a hard connection that is via the Ethernet cable plugged directly to the router.

You don't need the setup disk check out my four tips here for Wireless Printer and Wireless Routers.

The setup disc that you maybe able to find is just a wizard and can't setup printers to your router like in my first tip.

Are you trying to install the router.
You can do it manually without the CD.
MAke sure that your computer is able to go online through the modem.
If your computer is able to go online through the modem
Then you need to connect the computer to the router ad the modem to the router.
open the set up page of the router and change the settings of the router according to the ISP.

If router is brand new you should have a set up disk. the set up disk will walk you through it or you might log onto Belkin site to see a walk through set up. If you can access internet from modem to router to internet. That means router is functioning properly. To go completely wireless you will need to secure your network and setup your access codes. Definitely use the setup disk to do this. A unsecured wireless network is a nightmare waiting to happen. Good luck
