Hello, I recently bought the router stated above, and in the box came a power chord the router and one Ethernet cable. I would like to know exactly what am I supposed to do. In the quick setup it says I need to connect a second cable but I only have one Ethernet cable. I also don't have a modem, so I am completely lost on what I need to do, can anyone please guide me through what I need in order to make this setup work?
