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.

Connect your computer to the router using ethernet port. open the command prompt. type ipconfig then press enter. it will give you ipaddress and default gate way. copy the default gateway and open the browser - Internet explorer. type the default gate way no in the address bar. eg 192.168.0.1 then press enter. you will be asked to enter user name and password. just type in those info.
