Support CDs of the wireless Internet are used to configure the router in an easy way but you can always choose the alternate version of configuring. Connect to your router using a network cable, go to Start > Run > type "cmd" and press Enter. Then type ipconfig /all and note the IP address you find next to Default Gateway. Type that address into a browser window and the administration page of your router will load from where you can configure as you would use the Support CD. But first you need to master reset the router by plugging something sharp on the reset spot on the back of the router. Keep that button pressed for about 30 seconds, release it and follow the instructions above.
