Does the Netgear WN2500RP (N600 WiFi Range Extender) only extend wifi, or can it be connected to a modem and generate its own wifi?

I have a Motorola surfboard sb6121 (which does not generate wifi on its own and needs a router) and am trying to hook it up to my Netgear WN2500RP (N600 WiFi Range Extender) in an attempt to generate a wifi signal.

I can't tell if the Netgear WN2500RP (N600 WiFi Range Extender) is capable of generating wifi when attached to the Motorola surfboard sb6121, or if it requires an intermediary to generate the wifi.

I have a MacBook Pro running Yosemite.

Help is much appreciated. Thank you!

A range extender does what it says, it extends an existing wifi network. Whether your device could act as a wifi router should be in its manual but I think it will not.
With alternative firmware all range extenders and wifi print servers can become access points and vice versa...

And; unfortunately, that router has no built-in DHCP server so it won't give out ip addresses to devices which connect to it and the user's manual specifically says not to use one of its network ports for the connection to a router or modem.  You'll need to buy another router:

It is same hardware as most wifi routers, over time it will have openwrt and ddwrt. With present firmware sadly you are out of luck.

The 2500 doesn't have a wan/internet port so, unless somebody really pulls a rabbit out of their hat, there is no hardware to support a nat firewall.  Look at the manual!
It is either 4 or 5 port switch that can be partitioned to firmwares liking.
Probably 5th port is just not soldered to SoC board.
I have seen "wirelss print server" transforming into access point...
