I just got a new router. It is an asus RT-N66R. I set it up and everything. Does it need to be connected to my modem? Because

Solution
Yes, the router needs to be connected to the cable modem on the Ethernet port. Connect the blue Ethernet WLAN port to the modem and then connect your computers Ethernet adapter to one of the yellow Ethernet ports on the router.
