A:Answer It's not really for FiOS. This is a cablemodem/router. With FiOS, you don't need the "cablemodem" part. FiOS is not "cable" and does not come to your home via coax. FiOS fiber runs to your home and into a device, usually just outside the home, who's name escapes me at the moment. The output from that devices is Ethernet. You connect this device to the "WAN Input" port on a regular router with an ethernet cable. The router has (usually) 4 Ethernet ports so you can run wires to other devices (like an XBox), and you can set up wifi to be broadcast to share the signal.
When you get internet from Cox or another cable company, it comes into your house via coax (round white cable, hole on one end with a small wire sticking out). If you have that, you would use a cablemodem/router like this. You plug the coax into the coax input port. Everything else on the cablemodem/router looks and behaves like it's "regular router" counterpart, including (usually) 4 Ethernet ports and wifi capability.
So go buy yourself a regular router. If you like Netgear (I do) they make several. (There are more regular routers out there than cablemodem/routers).
Sorry if this was too rambling or confusing. :)
