Section 1 - Product Overview
Introduction
The DSL-G225 Wireless N300 ADSL2+/VDSL2 Modem Router is everything you need for high-speed Internet access in your home. It combines a
VDSL2 modem and high-end wireless router together to create a single, easy-to-use device that connects to the Internet, and shares that connection
with all of your devices. Plug in a USB storage drive to eortlessly share your documents, video, photos, and music or connect to a printer.
Combination ADSL2+/VDSL2 Modem and Router
The DSL-G225 combines the functionality of a high-speed VDSL2 broadband modem and a wireless router in one device, meaning there is no need
for separate modem and wireless router devices. Connect to your VDSL2 Internet Service Provider and share the Internet connection with both
wireless and wired devices. Lastly, the DSL-G225 gives you the option to connect to your broadband modem using the WAN Ethernet port so you
have the exibility to access the Internet via DSL, Cable, or other connection types.
Fast and Reliable Home Network
With theWireless N300 ADSL2+/VDSL2 Modem Router, you can create a home network with high-speed wireless, for a reliable connection to wireless
devices, and Fast Ethernet LAN ports for quick wired connection speeds. 802.11n wireless gives you the bandwidth to stream HD multimedia and
feature-rich content across your home, so you can browse the Internet and stream digital media at combined speeds of up to 300 Mbps1. Using
Quality of Service (QoS) technology the DSL-G225 can be congured to give certain devices network priority over others so their Internet connection
is always optimized.
USB Port for Additional Connectivity
The DSL-G225 features a built-in USB port to provide additional functionality for your network. Attach a printer or portable hard drive to share les
with everyone, or even plug in a 3G/4G USB modem to enjoy Internet connectivity in places without a wired Internet connection.
Easy to Set Up
Get the DSL-G225 up and running in no time using the intuitive web-based conguration utility. Simply connect the DSL-G225 to your computer,
launch the conguration utility, and follow a few easy steps to get your home network congured. You can also set up a encrypted network with
the touch of a button using Wi-Fi Protected Setup (WPS). Simply press the WPS button to eortlessly establish an encrypted connection to a new
device. Protect your network with WPA/WPA2 wireless encryption and a built-in NAT rewall, so you can shop online and do your online banking
with condence.
* Maximum wireless signal rate derived from IEEE Standard 802.11b, 802.11g, and 802.11n specications. Actual data throughput will vary. Network
conditions and environmental factors, including volume of network trac, building materials and construction, and network overhead, lower actual
data throughput rate. Environmental conditions will adversely aect wireless signal range.

and g standards, so you can use keep your existing 802.11b and g devices.
• Precise ATM Trac Shaping - Trac shaping is a method of controlling the ow rate of ATM data cells. This
function helps to establish Quality of Service for ATM data transfer.
• High Performance - Very high rates of data transfer are possible with the router-providing up to 100 Mbps
downstream for VDSL2
• Full Network Management -The DSL-G225 incorporates SNMP (Simple Network Management Protocol) support
for web-based management and text-based network management via a Telnet connection.
• Easy Installation - The DSL-G225 can be congured and managed easily using a web-based UI. Any common
web browser software can be used to manage the router.
• USB Support - The DSL-G225 provides a USB port for easy le sharing and printer sharing. The DSL-G225
supports USB storage devices to share les through a SAMBA le server. It also supports sharing USB printers
to network members. Besides the sharing function, the DSL-G225 also supports connection to the Internet via
a USB 3G/4G modem.
* Maximum wireless signal rate derived from IEEE Standard 802.11b, 802.11g, and 802.11n specications. Actual data throughput will vary. Network conditions and environmental

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-G225
Wireless N300 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-G225 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-G225 will be providing this
functionality.

Section 2 - Installation
Wireless Installation Considerations
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, however, 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 (.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 in not in use.
