Section 2 – Installation
Installation
This section will guide 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 or in the attic or garage.
Before You Begin
Please read and make sure you understand all the prerequisites for proper installation of your new Router. Have all the necessary information and
equipment on hand before beginning the installation.
Installation Notes
In order to establish a connection to the Internet it will be necessary to provide information to the Router that will be stored in its memory. For some
users, only their account information (Username and Password) is required. For others, various parameters that control and define the Internet
connection will be required. You can print out the two pages below and use the tables to list this information. This way you have a hard copy of all
the information needed to setup the Router. If it is necessary to reconfigure the device, all the necessary information can be easily accessed. Be
sure to keep this information safe and private.
Low Pass Filters
Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to avoid
mutual interference. A low pass filter device can be installed for each telephone that shares the line with the ADSL line. These filters are easy to
install passive devices that connect to the ADSL device and/or telephone using a standard telephone cable. Ask your service provider for more
information about the use of low pass filters with your installation.
Operating Systems
The DSL-2730U uses an HTML-based web interface for setup and management. The web configuration manager may be accessed using any
operating system capable of running web browser software, including Windows 98 SE, Windows ME, Windows 2000, Windows XP, Windows Vista,
Windows 7, and Windows 8.
D-Link DSL-2730U User Manual 4

Section 2 – Installation
Web Browser
Any common web browser can be used to configure the Router using the web configuration management software. The program is designed to work
best with more recently released browsers such as Opera, Microsoft Internet Explorer® version 6.0, Netscape Navigator® version 6.2.3, or later
versions. The web browser must have JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not been
disabled by other software (such as virus protection or web user security packages) that may be running on your computer.
Ethernet Port (NIC Adapter)
Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This connection is an Ethernet connection
and therefore requires that your computer be equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port
already installed. Likewise, most fully assembled desktop computers come with an Ethernet NIC adapter as standard. If your computer does not have
an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you need to install an adapter, follow the installation
instructions that come with the Ethernet NIC adapter.
Additional Software
It may be necessary to install software on your computer that enables the computer to access the Internet. Additional software must be installed if
you are using the device as a simple bridge. For a bridged connection, the information needed to make and maintain the Internet connection is
stored on another computer or gateway device, not in the Router itself.
If your ADSL service is delivered through a PPPoE or PPPoA connection, the information needed to establish and maintain the Internet connection
can be stored in the Router. In this case, it is not necessary to install software on your computer. It may however be necessary to change some
settings in the device, including account information used to identify and verify the connection.
All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings must reside in a TCP/IP enabled
device on the LAN side of the bridge, such as a PC, a server, a gateway device, such as a router, or similar firewall hardware. The IP address can be
assigned in a number of ways. Your network service provider will give you instructions about any additional connection software or NIC configuration
that may be required.
D-Link DSL-2730U User Manual 5

Section 2 – Installation
Information you will need from your ADSL service provider
Username
This is the Username used to log on to your ADSL service provider’s network. Your ADSL service provider uses this to identify your account.
Password
This is the Password used, in conjunction with the Username above, to log on to your ADSL service provider’s network. This is used to verify the
identity of your account.
WAN Setting / Connection Type
These settings describe the method your ADSL service provider uses to transport data between the Internet and your computer. Most users will use
the default settings. You may need to specify one of the following WAN Setting and Connection Type configurations (Connection Type settings listed
in parenthesis):
 PPPoE/PPPoA (PPPoE LLC, PPPoA LLC or PPPoA VC-Mux)
 Bridge Mode (1483 Bridged IP LLC or 1483 Bridged IP VC Mux)
 IPoA/MER (Static IP Address) (Bridged IP LLC, 1483 Bridged IP VC Mux, 1483 Routed IP LLC, 1483 Routed IP VC-Mux or IPoA)
 MER (Dynamic IP Address) (1483 Bridged IP LLC or 1483 Bridged IP VC-Mux)
Modulation Type
ADSL uses various standardized modulation techniques to transmit data over the allotted signal frequencies. Some users may need to change the
type of modulation used for their service. The default DSL modulation (ADSL2+ Multi-Mode) used for the Router automatically detects all types of
ADSL, ADSL2 and ADSL2+ modulation.
Security Protocol
This is the method your ADSL service provider will use to verify your Username and Password when you log on to their network. Your Router
supports the PAP and CHAP protocols.
VPI
Most users will not be required to change this setting. The Virtual Path Identifier (VPI) is used in conjunction with the Virtual Channel Identifier (VCI)
to identify the data path between your ADSL service provider’s network and your computer. If you are setting up the Router for multiple virtual
connections, you will need to configure the VPI and VCI as instructed by your ADSL service provider for the additional connections. This setting can
be changed in the WAN Settings window of the web management interface.
VCI
Most users will not be required to change this setting. The Virtual Channel Identifier (VCI) is used in conjunction with the VPI to identify the data path
between your ADSL service provider’s network and your computer. If you are setting up the Router for multiple virtual connections, you will need to
configure the VPI and VCI as instructed by your ADSL service provider for the additional connections. This setting can be changed in the WAN
Setup window of the web management interface.

Information you will need about your LAN or computer
Ethernet NIC
If your computer has an Ethernet NIC, you can connect the DSL-2730U to the Ethernet port using an Ethernet cable.
DHCP Client status
Your DSL-2730U ADSL 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 DSL-2730U will assign are from 192.168.1.2 to
192.168.1.254. Your computer (or computers) needs to be configured to obtain an IP address automatically (that is, they need to be configured as
DHCP clients.)
It is recommended that you backup or record this information here, or in some other secure place, in case you have to re-configure your ADSL
connection in the future.
Once you have the above information, you are ready to setup and configure your DSL-2730U ADSL Router.
