Getting to know your CENTRIA
NETGEAR CENTRIA is an all-in-one device with three essential functions.
•
Back up automatically. All your computers—Windows PCs and Macs—can back up
incrementally on the CENTRIA internal hard drive or on an external USB storage drive.
•
Share easily. Store your files and media on your CENTRIA and access or stream them
from any Internet-enabled device.
•
Connect quickly. Enjoy high-performance connectivity throughout your home with your
900 Mbps, dual-band WiFi router.
CENTRIA comes in two models: WNDR4720, which comes with a 2 TB hard drive, and
WNDR4700, for which you provide your own hard drive. You can upgrade the hard disk drive at
any time. Both models have two SuperSpeed USB 3.0 ports for adding even more storage,
should you need it. An SD card reader affords simple, single-click backup of media to the internal
hard drive.

If any parts are incorrect, missing, or damaged, contact your NETGEAR dealer. Keep the
carton and original packing materials, in case you need to return the product for repair.
Position CENTRIA
The router lets you access your network from virtually anywhere within the operating range of
your wireless network. However, the operating distance or range of your wireless connection
can vary significantly depending on the physical placement of your router. For example, the
thickness and number of walls the wireless signal passes through can limit the range. For
best results, place your router:

CENTRIA WNDR4700/WNDR4720
•
Near the center of the area where your computers and other devices operate and
preferably within line of sight to your wireless devices.
•
So it is accessible to an AC power outlet and near Ethernet cables for wired computers.
•
In an elevated location such as a high shelf, keeping the number of walls and ceilings
between the router and your other devices to a minimum.
•
Away from electrical devices that are potential sources of interference. Equipment that
might cause interference includes ceiling fans, home security systems, microwaves,
computers, the base of a cordless phone, or 2.4 GHz cordless phone.
•
Away from any large metal surfaces, such as a solid metal door or aluminum studs. Large
expanses of other materials such as glass, insulated walls, fish tanks, mirrors, brick, and
concrete can also affect your wireless signal.
When there is more than one wireless network in the area and they use the same channel,
that can create interference in some instances. If this happens, you can use a different radio
frequency channel to reduce interference. The recommended channel spacing is five
channels. Fr example, different networks in the same area could use Channels 1 and 6, or 6
and 11.
Hardware Features
Before you cable your router, take a moment to become familiar with the front, side, and back
panels and the label. Pay particular attention to the LEDs on the front panel.
Front and Side Panel
The router front panel has status LEDs and icons. Buttons and connectors are on the side.
