DSL-G804V Wireless ADSL Router User’s Guide

About This User’s Guide

This user’s guide provides instructions on how to install the DSL-G804V Wireless ADSL Router and use it to connect a computer or Ethernet LAN to the Internet.

If you are using a computer with a functioning Ethernet port, the quickest and easiest way to set up the DSLG804V is to insert the Installation CD into the CD-ROM drive of your computer and follow the instructions provided in the Quick Installation Guide.

Before You Start

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 Overview

The procedure to install the Router can be described in general terms in the following steps:

1. Gather information and equipment needed to install the device. Before you beg in the actual installation make sure you have all the necessary information and equipment.

2. Install the hardware, that is, connect the cables (Ethernet and telephone) to the device and connect the power adapter.

3. Check the IP settings on your computer and change them if necessary so the computer can access the web-based software built into the Router.

4. Use the web-based management software to configure the device to suit the requirements of your ADSL account.

Installation Requirements

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. Yo u 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 standard telephone cable. Ask your service provider for more information about the use of low pass filters with your installation.

Operating Systems

The DSL-G804V 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, Windows NT, Windows 2000, Windows XP and Me.

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 5.0, Netscape Navigator® version 4.5, 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.

DSL-G804V Wireless ADSL Router User’s Guide

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 equ ipment. If your computer does not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the installation instructions that come with the Ethernet NIC ad apter.

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 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, PPPoA or CLIP (IPoA) 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 co nnections, th e 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.

About CLIP Connections (RFC 1577)

Classical IP over ATM (CLIP) connections may require global IP settings for the device. Your service provider will give you IP settings information if needed. Some CLIP connections function like peer-to-peer connections and therefore do not require IP settings on the WAN interface.

This is the Username used to log on to your ADSL service provider’s network. It is commonly in the form − user@isp.com. Your ADSL service provider uses this to identify your account.

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.

This is the method your ADSL service provider uses to send and receive data between the Internet and your computer. Your Modem supports the following connection protocols: PPPoE, PPPoA, PPPoA with DHCP, Bridge, and CLIP (IPoA).

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 (MMODE) used for the Router automatically detects all types of ADSL modulation. However, if you are instructed to specify the modulation type used for the Router, you have three alternatives: G.LITE, G.DMT and T1.413

This is the method your ADSL service provider will use to verify your Username and Password when you log on to their network. Your Modem supports the PAP and CHAP protocols.

This is the Virtual Path Identifier (VPI). It is used in conjunction with the Virtual Channel Identifier (VCI) below, to identify the data path between your ADSL service provider’s network and your computer.

What is ADSL?

Asymmetric Digital Subscriber Line (ADSL) is an access technology that utilizes ordinary copper telephone lines to enable broadband high-speed digital data transmission and interactive multimedia applications for business and residential customers.

ADSL greatly increases the signal carrying capacity of copper telephone lines witho ut interfering with regular telephone services. For the ADSL user, this means faster downloads and more reliable connectivity. ADSL devices make it possible to enjoy benefits such as high-speed Internet access without experiencing any loss of quality or disruption of voice/fax telephone capabilities.

ADSL provides a dedicated service over a single telephone line operating at speeds of up to 8 Mbps downstream and up to 640 Kbps upstream, depending on local telephone line conditions. A secure point-to-point co nnection is established between the user and the central office of the service provider.

D-Link ADSL devices incorporate the recommendations of the ADSL Forum regarding framing, data format, and upper layer protocols.

Hardware Installation

The DSL-G804V maintains five separate interfaces, four Ethernet and one ADSL interface. Place the Router in a location where it can be safely 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 precautions.

The access point 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

CAUTION: The Router must be used with the power adapter included with the device.

To power on the Router:

1. Insert the DC 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. You should see the Power LED indicator light up and remain lit. The Status LED should light solid green and begin to blink after a few seconds.

3. If the Ethernet port is connected to a working device, check the Ethernet Link/Act LED indicators to make sure the connection is valid. The Router will attempt to establish the ADSL connection, if the ADSL 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 depressing the reset button for a few seconds while the device is powered on. Use a ballpoint or paperclip to gently push down the reset button. Remember that this will wipe out any settings stored in flash memory including user account information and LAN IP settings. The factory default IP address of the Router is 192.168.1.1 and the subnet mask is 255.255.255.0, the default management Username is admin and the default Password is admin.

DSL-G804V Wireless ADSL Router User’s Guide

Network Connections

Network connections are provid ed through the ADSL por t and the four Ethernet por ts on the back of the Router . See the Rear Panel diagram above and the illustrations below for examples.

Connect ADSL Line

Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. Plug one end of the cable into the ADSL 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 ADSL connection represents the WAN interface, the connection to the Internet. It is the physical link to the service provider’s network backbone and ultimately to the Internet.

Connect Router to Ethernet

The Router may be connected to a single computer or Ethernet device through the 10BASE-TX Ethernet port on the rear panel. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a speed of 10/100 Mbps only. 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 port on the Router is 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-thr ough 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 as shown in the diagram below:

If you wish to reserve the uplink port on the switch o hub for another device, connect to any on the othe MDI-X ports (1x, 2x, etc.) with a crossed cable.

DSL-G804V Wireless ADSL Router User’s Guide

Computer to Router Connection

You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a PC using the Ethernet cable provided as shown in this diagram.

Power On Router

To power on the Router:

1. Insert the DC 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. You should see the Power LED indicator light up and remain lit. The Status LED should light solid green and begin to blink after a few seconds.

3. If you have the Router connected to your network you can look at the Ethernet Link/Act LED indicators to make sure they have valid connections. The Router will attempt to establish the ADSL connection, if the ADSL line is connected and the connection is properly configured this should light up after several seconds.

Factory Reset Button

The Router may be reset to the original factory default settings by depressing the reset button for a few seconds while the device is powered on. Use a ballpoint or paperclip to push down the reset button. Remember that this will wipe out any settings stored in flash memory including IP settings. The factory default IP address of the Router is 192.168.1.1 and the subnet mask is 255.255.255.0.

DSL-G804V Wireless ADSL Router User’s Guide

Basic Router Configuration

The first time you setup the Router it is recommended that you configure the WAN connection using a single computer making sure that both the computer and the Router are not connected to the LAN. Once the WAN connection is functioning properly, you may continue to make changes to Router configuration including IP settings and DHCP setup. This chapter is concerned with using your computer to configur e the WAN co nnection . The following chapter describes the various menus used to configure and monitor the Router including how to change IP settings and DHCP server setup.

Wan Configuration Summary

1. 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. To access the management software your computer must be able to “see” the Router. Your computer can see the Router if it is in the same “neighborhood” or subnet as the Router. This is accomplished by making sure your computer has IP settings that place it in the same subnet as the Router. 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. The next section describes how to change the IP configuration for a computer running a Windows operating system to be a DHCP client.

2. Configure the WAN Connection Once your are able to access the configuration software you can

proceed to change the settings required to establish th e ADSL connection and connect to the service provider’s network. There are different methods used to establish the connection to the service provider’s network and ultimately to the Internet. You shou ld know what Encapsulation and conn ection type you are required to use for your ADSL service. It is also possible that you must chang e the PVC settings used for the ADSL connection. Your service provider should provide all the information you need to configure the WAN connection.

Configuring IP Settings on Your Computer

In order to configure your system to receive IP settings from the Router it must first have the TCP/IP protocol installed. If you have an Ethernet port on your computer, it probably already has TCP/IP protocol installed. If you are using Windows XP the TCP/IP is enabled by default for standard installations. Below is an illustrated example of how to configure a Windows XP system to automatically obtain IP settings from the Router. Following this example is a step-by-step description of the procedures used on the other Windows operating systems to first check if the TCP/IP protocol has been installed; if it is not, instructions are provided for installing it. Once the protocol has been installed you can configure the system to receive IP settings from the Router.

For computers running non-Windows operating systems, follow the instructions for your OS that configure the system to receive an IP address from the Router, that is, configure the system to be a DHCP client.

If you are using this Router to provide Internet access for more than one computer, you

Note

can use these instructions later to change the IP settings for the other computers. However, you cannot use the same IP address since every computer must have its own IP address that is unique on the local network.

DHCP Server

DHCP stands for Dynamic Host Control Protocol. The DHCP protocol allows your router to dynamically assign

IP addresses to PCs on your network if they are configured to obtain IP addresses automatically.

Figure 3-13. Home – DHCP Server

None DHCP

The DHCP Server is disabled; you will need to manually assig n a fixed IP address to each PCs on your network ,

and set the default gateway for each PCs to the IP address of the router.

DHCP Server

You can configure parameters of the DHCP Server including the IP pool (starting IP address and ending IP

address to be allocated to PCs on your network), lease time for each assigned IP address (the period of time the

IP address assigned will be valid), DNS IP address and the gateway IP address. These details are sent to the

DHCP client (i.e. your PC) when it requests an IP address from the DHCP server. If you check “Use Router as a

DNS Server”, the ADSL Router will perform the domain name lookup, find the IP address from the outside

network automatically and forward it back to the requesting PC in the LAN (your Local Area Network).

DNS Configuration

A Domain Name System (DNS) contains a mapping table for domain name and IP addresses. On the Internet,

every host has a unique and user-friendly name (domain name) such as www.helloworld.com and an IP address.

An IP address is a 32-bit number in the form of xxx.xxx.xxx.xxx, for example 192.168.1.1. You can think of an I P

address as a telephone number for devices on the Internet, and the DNS will allow you to find the telephone

number for any particular domain name. As an IP Address is hard to remember, the DNS converts the friendly

name into its equivalent IP Address.

Figure 3-16. Home – DNS Configuration

You can obtain a Domain Name System (DNS) IP address automatically if your ISP has provided it when you

logon, check the Enable box. Usually when you choose PPPoE or PPPoA as your WAN - ISP protocol, the ISP

Virtual Server

NAT can act as a “natural” Internet firewall; your router protects your network from being accessed by outside

users. When using NAT, all incoming connection attempts will point to your router, unless you specifically

create Virtual Server entries to forward those ports to a PC on your network.

TCP/IP and UDP types, which is port with 16-bit number that used to identify which the application p rogram

(usually a server) should be delivered from an incoming connections should be delivered to. Some ports have

numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are

referred to as “well-known ports”. Servers follow the well-known port assignments so clients can locate them.

Virtual Sever utilizes protocol,

Note

If you have disabled the NAT option in the WAN-ISP section, the Virtual Server function will hence be invalid.

If the DHCP server option is enabled, you have to be very careful in assigning the IP addresses of the virtual servers in order to avoid conflicts. The easiest way of configuring Virtual Servers is to manually assign static IP address to each virtual server PC, with an address that does not fall into the range of IP addresses that are to be issued by the DHCP server. You can configure the virtual server IP address manually, but it must still be in the same subnet as the router.

DSL-G804V Wireless ADSL Router User’s Guide

Add Virtual Server

When your router needs to allow outside users to access internal servers, e.g. a web server, FTP server, Email

server or game server, the router can act as a “virtual server”. You can set up a local server with a specific port

number for the service to use, e.g. web/HTTP (port 80), FTP (port 21), Telnet (port 23), SMTP (port 25), or

POP3 (port 110). When an incoming access request to the router for a specified port is received, it will be

forwarded to the corresponding internal server.

If you like to remote access your Router through the Web/HTTP at all time, you would need to enable port

number 80 (Web/HTTP) and map to Router’s IP Address. Then all incoming HTTP requests from you (Remote

side) will be forwarded to the Router with IP address of 192.168.0.1. Since port number 80 has already been

predefined, next to the Application click Helper. A list of predefined rules window will pop and select

HTTP_Sever.

Perfect Forward Secrecy

Choose whether to enable PFS using Diffie-Hellman public-key cryptography to change encryption keys during the second phase of VPN negotiation. This function will provide better security, but extends the VPN negotiation time. Diffie-Hellman is a public-key cryptography protocol that allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for Modular Exponentiation Groups.

Pre-shared Key

This is for the Internet Key Exchange (IKE) protocol, a string from 4 to 128 characters. Both sides should use the same key. IKE is used to establish a shared security policy and authenticated keys for services (such as IPSec) that require a key. Before any IPSec traffic can be passed, each router must be able to verify the identity of its peer. This can be done by manually entering the pre-shared key into both sides (router or hosts).

are employed. Wireless client may have selected open or share key setting and still can get access to the Access point, only if correct WEP Key is presented.

WEP Encryption

To prevent unauthorized wireless stations from accessing data transmitted over the network, the router offers highly secure data encryption, known as WEP. If you require high security for transmissions, there are two alternatives to select from: WEP 64 and WEP 128. WEP 128 will offer increased security over WEP 64.

Default Used WEP Key (0-3)

Enter the key to encrypt wireless data. To allow encrypted data transmission, the WEP Encryption Key values on all wireless stations must be the same as the router. There are four keys for your selection. The input format is in HEX style, 5 and 13 HEX codes are required for WEP64 and WEP128 respectively, the separator is “-“. For example, using WEP64, 11-22-33-44-55 is a valid key, whilst 1122334455 is invalid.
