Section 1 - Product Overview
Smooth Streaming with Wireless AC
The DSL-G2452GR uses the latest Wireless AC technology, which provides transfer rates of up to 1.2 Gbps (866 AC + 300 N).
The router operates on both the 2.4 GHz and 5 GHz wireless bands at the same time using concurrent dual-band technology
and two external antennas. This allows you to browse the web, chat, and e-mail using the 2.4 GHz band, while simultaneously
streaming digital media, playing online games, or making Internet voice calls on the 5 GHz band.
Designed for Optimal Wireless Coverage
The DSL-G2452GR’s antennas have been carefully designed to ensure that you will get little to no dead space in any
environment. The high-powered amplier sends the signal into the farthest corners of your home, while high-gain antennas
extend the maximum range of wireless signals. Furthermore, the DSL-G2452GRs multiple external antennas improve wireless
reception by bringing signals to where they are most needed to achieve the best possible performance.
File Sharing Right at Your Fingertips
The DSL-G2452GR lets you connect a USB storage device and instantly share documents, movies, pictures, and music. You can
put your music library on a USB drive and share it with your entire home. You can show photos on the living room TV while
a family member watches a movie on their computer. You can stream media les to multiple devices without interruption,
or save them to your device for oine playback. The intuitive interface lets anyone immediately connect to a variety of
entertainment options stored on your own storage device.
Easy to Set Up
Setting up the DSL-G2452GR is easy with the D-Link easy setup wizard. Simply open the setup utility and follow a few easy
steps to get your home network up and running. You can also set up a WPA2 encrypted network with the touch of a button
using Wi-Fi Protected Setup (WPS). Simply press the respective WPS buttons on each devices to instantly establish an
encrypted connection to a new device. Your network will be encrypted with WPA/WPA2 wireless encryption and employ built-
in dual active rewalls (SPI and NAT) to help protect your network from unauthorized access.

Section 2 - Installation
Before you Begin
Installation
This section will walk you through the installation process. Placement of the router is very important. Do not place the router in
an enclosed area such as a closet, cabinet, attic, or garage.
Note: This installation section is written for users who are setting up their home Internet service with the DSL-G2452GR
Wireless AC1200 Dual-Band Gigabit ADSL2+/VDSL2 Modem Router for the rst time. If you are replacing an existing DSL
modem and/or router, you may need to modify these steps.
• Make sure to have your DSL service information provided by your Internet Service Provider handy. This
information is likely to include your DSL account's Username and Password. Your ISP may also supply you with
additional WAN conguration settings which are necessary to establish a connection. This information may
include the connection type (DHCP IP, Static IP, PPPoE, or PPPoA) and/or ATM PVC details.
• If you are connecting a considerable amount of networking equipment, it may be a good idea to take the time to
label each cable or take a picture of your existing setup before making any changes.
• We suggest setting up your DSL-G2452GR from a single device and verifying that it is connected to the Internet
before connecting additional devices.
• If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE connection software
such as WinPoET, BroadJump, or EnterNet 300 from your computer as the DSL-G2452GR will be providing this
functionality.

10D-Link DSL-G2452GR User Manual
Section 2 - Installation
The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within the
operating range of your wireless network. Keep in mind that the number, thickness and location of walls, ceilings, or other
objects that the wireless signals must pass through may limit the range. Typical ranges vary depending on the types of
materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to
follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link router and other network devices to a minimum -
each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that
the number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (0.5 meters), at a 45-degree
angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick!
Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better
reception.
3. Building materials make a dierence. A solid metal door or aluminum studs may have a negative eect on
range. Try to position access points, wireless routers, and computers so that the signal passes through drywall or
open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors,
le cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF
noise.
5. If you are using 2.4 GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home
security systems), your wireless connection may degrade dramatically or drop completely. Make sure your 2.4
GHz phone base is as far away from your wireless devices as possible. The base transmits a signal even if the
phone is not in use.
