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.

(The examples below are illustrated in Windows® XP. If you have a different operating system, the screenshots on your computer will look similar to the following examples.)
1. How do I configure my DSL-2730U Router without the CD-ROM?
Step 1 Connect your PC to the Router using an Ethernet cable.
Step 2 Open a web browser and enter the address http://192.168.1.1
Step 3 The default username is ‘admin’ and the default password is ‘admin’.
Step 4 If you have changed the password and cannot remember it, you will need to reset the Router to the factory default setting (see question 2), which will set the password back to ‘admin’.
2. How do I reset my Router to the factory default settings?
Step 1 Ensure the Router is powered on.
Step 2 Press and hold the reset button on the back of the device for approximately 1 second.
Step 3 This process should take around 1 to 2 minutes.
Note:
Resetting the Router to the factory default settings will erase the current configuration settings.
3. What can I do if my Router is not working correctly?
There are a few quick steps you can take to try and resolve any issues:
Step 1 Follow the directions in Question 2 to reset the Router.
Step 2 Check that all the cables are firmly connected at both ends.
Step 3 Check the LEDs on the front of the Router. The Power indicator should be on, the Status indicator should flash, and the DSL and LAN

Section 4 – Troubleshooting indicators should be on as well.
Step 4 Please ensure that the settings in the Web-based configuration manager, e.g. ISP username and password, are the same as the settings that have been provided by your ISP.
4. Why can’t I get an Internet connection?
For ADSL ISP users, please contact your ISP to make sure the service has been enabled/connected by your ISP and that your ISP username and password are correct.
5. What can I do if my Router can’t be detected by running the installation CD?
Step 1 Ensure the Router is powered on.
Step 2 Check that all the cables are firmly connected at both ends and all LEDs are working correctly.
Step 3 Ensure only one network interface card on your PC is activated.
Step 4 Click on Start > Control Panel > Security Center to disable the firewall.
Note:
There is a potential security issue if the firewall is disabled on your PC. Please remember to turn it back on once you have finished the whole installation procedure. This will enable you to surf the Internet without any problems.

Check Your IP Address
After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click on the OK button.
At the prompt, type ipconfig and press Enter.
This will display the IP address, subnet mask and the default gateway of your adapter.
If the address is 0.0.0.0, check your adapter installation, security settings and the settings on your router. Some firewall software programs may block a DHCP request on newly installed adapters.
If you are connecting to a wireless network at a hotspot (e.g. hotel, coffee shop, airport), please contact an employee or administrator to verify their wireless network settings.

Appendix B –Statically Assigning an IP Address
Statically Assigning an IP Address
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below:
Step 1
Windows® XP - Click on Start > Control Panel > Network Connections.
Windows® 2000 - From the desktop, right-click on the
My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your network adapter and select the Properties button.
Step 3
Highlight Internet Protocol (TCP/IP) and click on the Properties button.
Step 4
Click on the Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN IP address on your router.
Example: If the router’s LAN IP address is 192.168.1.1, make your IP address 192.168.1.X where X is a number between 2 and 254. Make sure that the number you choose is not in use on the network. Set the Default Gateway to be the same as the LAN IP address of your router
(192.168.1.1).
Set the Primary DNS to be the same as the LAN IP address of your router (192.168.1.1). The
Secondary DNS is not needed or you may enter a DNS server from your ISP.
Step 5
Click on the OK button twice to save your settings.
