You can use the on board set up wizard to configure the router or manually configure the router from scratch by opening a browser and going to the following address if your using the default settings:
192.168.0.1.
Try a factory reset using the button in back if you can't seem to access the router.
Try Opera or FF? If IE 8 or 9, set compatibility mode and test again.
The CD is not needed to set up the router as the set up on the CD is the same as what is on board the router.
Good Luck, ehh!
