Information you will need about this Router
Username
This is the username needed access the router
’s
web management interface. When you attempt to connect to the device through a web browser you will be prompted to enter
this username. The default username for the router
is “
Admin
”
.
Alternatively, you can also try “user”
Password
This is the password you will be prompted to enter when you access the router
’s
web management interface. The default p
assword is “
Admin
”
. Alternatively, you can also try
“user”
LAN IP Addresses for the Router
This is the IP address you will enter into the Address field of your web browser to access the router
’s configuration
Graphical User Interface (GUI) using a web browser. The
default IP address is
10.0.0.138
. This may be changed to suit any IP address scheme the user desires. This address will be the base IP address used for DHCP service on
the LAN when DHCP is enabled.
LAN Subnet Mask for the Router
This is the subnet mask used by the Router, and will be used throughout your LAN. The default subnet mask is
255.255.255.0
. This can be changed later.
Information you will need about your LAN or computer
Ethernet NIC
If your computer has an Ethernet NIC, you can connect the router to this Ethernet port using an Ethernet cable. You can also use the Ethernet ports on the router to connect
to other computer or Ethernet devices.
DHCP Client status
Your VDSL router is configured, by default, to be a DHCP server. This means that it can assign an IP address, subnet mask, and a default gateway address to computers on
your LAN. The default range of IP addresses the unit will assign are from
10.0.0.139
to
10.0.0.254
. Your computer (or computers) needs to be configured to obtain an IP
address automatically (that is, they need to be configured as DHCP clients.)
Once you have the above information, you are ready to setup and configure your VDSL router.

Device Installation
The router connects two separate physical interfaces, a VDSL (WAN) and an Ethernet (LAN) interface. Place the router in a location where it can be connected to the various
devices as well as to a power source. The router should not be located where it will be exposed to moisture or excessive heat. Make sure the cables and power cord are
placed safely out of the way so they do not create a tripping hazard. As with any electrical appliance, observe common sense safety procedures.
The router can be placed on a shelf or desktop, ideally you should be able to see the LED indicators on the front if you need to view them for troubleshooting.
Power on Router
The router must be used with the power adapter included with the device.
1.
Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the router and plug the adapter into a suitable nearby power source.
2.
Press the Power button into the on position. You should see the Power LED indicator light up and remain lit.
3.
If the Ethernet port is connected to a working device, check the Ethernet LED indicators to make sure the connection is valid. The router will attempt to establish the
VDSL connection, if the VDSL line is connected and the router is properly configured this should light up after several seconds. If this is the first time installing the
device, some settings may need to be changed before the router can establish a connection.
Factory Reset Button
The router may be reset to the original factory default settings by using a ballpoint pen or paperclip to gently push down the reset button in the following sequence:
1.
Press and hold the reset button while the device is powered on for 10-15 seconds.
2.
Release the reset button.
Remember that this will wipe out any settings stored in flash memory including user account information and LAN IP settings. The device settings will be restored to the
factory default IP address
10.0.0.138
and the subnet mask is
255.255.255.0.
The default management u
sername is “
user
” and the default
p
assword is “
user
”
.

Network Connections
Connect VDSL Line
Use the VDSL cable included with the router to connect it to a telephone wall socket or receptacle. Plug one end of the cable into the VDSL port (RJ-11 receptacle) on the
rear panel of the router and insert the other end into the RJ-11 wall socket. If you are using a low pass filter device, follow the instructions included with the device or given to
you by your service provider. The VDSL
connection represents the WAN interface, the connection to the Internet. It is the physical link to the service provider’s ne
twork
backbone and ultimately to the Internet.
Connect Router to Ethernet
The router may be connected to a single computer or Ethernet device through the Ethernet ports on the rear panel. Any connection to an Ethernet concentrating device such
as a switch or hub must operate at a speed of 10/100Mbps. When connecting the router to any Ethernet device that is capable of operating at speeds higher than 10Mbps, be
sure that the device has auto-negotiation (NWay) enabled for the connecting port. Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 ports on the router are a
crossed port (MDI-X). Follow standard Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the router directly to a PC or
server use a normal straight-through cable. You should use a crossed cable when connecting the router to a normal (MDI-X) port on a switch or hub. Use a normal straight-
through cable when connecting it to an uplink (MDI-II) port on a hub or switch. The rules governing Ethernet cable lengths apply to the LAN to router connection. Be sure that
the cable connecting the LAN to the router does not exceed 100 meters.
Hub or Switch to Router Connection
Connect the router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable. If you wish to reserve the uplink port on the switch or hub for another
device, connect to any on the other MDI-X ports (1x, 2x, etc.) with a crossed cable.
Computer to Router Connection
You can connect the router directly to an Ethernet adapter card (NIC) installed on a PC using the Ethernet cable provided.

Getting Started
This section will show you how to set up and configure your new D-Link router using the Web-based configuration utility.
How to connect to the Web User Interface
Connect to the Router
To configure the WAN connection used by the router it is first necessary to communicate with the router through its management interface, which is HTML-based and can be
accessed using a web browser. The easiest way to make sure your computer has the correct IP settings is to configure it to use the DHCP server in the router.
To access the web user interface, open a web-browser such as Internet Explorer and
enter the IP address of the router (
10.0.0.138
) into the address bar and press the
Enter
key on your keyboard.
Type “
Admin
”
in the User Name field
and “
Admin
” in the Password field
, and enter
the validation
code. Click the
Login
button to proceed. If you get a
Page Cannot be

error, please refer to the Troubleshooting section for assistance.
Tick the
Remember my login info on this computer
option to allow the browser to
remember the login information for the next login.
