it is a modem with a built-in wireless router as often defined by Verizon. I could define that as any modem that doesn't use true bridge mode, can function as a router (Wired or Wireless), or has NAT support.
Did you purchase a separate Router by any chance at a store or did you get one from Verizon either through their store or one you asked for over the phone? It may be a fee that can be taken off, as the supplied modem or router Verizon gives for service hook-up is often free.
