Can a router be used without a modem?

Yes, you can use a router without amodem, provided it is actually a modem withrouter functionality. That's not what you bought, though. Amodem acts as a buffer between your network and theinternet, so I highly recommend you don't even try to connect yourrouter directly to the internet.
