Section 1 - Product Overview Package Contents • • • • • • DSL-2640U Wireless ADSL Router Power Adapter CD-ROM with User Manual One twisted-pair telephone cable used for ADSL connection One straight-through Ethernet cable One Quick Installation Guide Note: Using a power supply with a different voltage rating than the one included with the DSL-2640U will cause damage and void the warranty for this product.
Section 1 - Product Overview 11 Features • PPP (Point-to-Point Protocol) Security – The DSL-2640U ADSL Router supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections. The Router also supports MSCHAP. • DHCP Support – Dynamic Host Configuration Protocol automatically and dynamically assigns all LAN IP settings to each host on your network. This eliminates the need to reconfigure every host whenever changes in network topology occur.
Section 1 - Product Overview • G.hs (Auto-handshake) – This allows the Router to automatically choose either the G.lite or G.dmt ADSL connection standards. • High Performance – Very high rates of data transfer are possible with the Router. Up to 8 Mbps downstream bit rate using the G.dmt standard. • Full Network Management – The DSL-2640U incorporates SNMP (Simple Network Management Protocol) support for web-based management and text-based network management via an RS-232 or Telnet connection.

Section 2 – Installation 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, 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.
Section 2 – 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.
Section 2 – Installation 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.
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.
Section 2 – Installation 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.
Section 2 – Installation Information you will need about DSL-2640U Username This is the Username needed to access the Router’s 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.” The user cannot change this. Password This is the Password you will be prompted to enter when you access the Router’s management interface. The default Password is “admin.” The user may change this.
Section 2 – Installation Information you will need about your LAN or computer : Ethernet NIC If your computer has an Ethernet NIC, you can connect the DSL-2640U to this Ethernet port using an Ethernet cable. You can also use the Ethernet ports on the DSL-2640U to connect to other computer or Ethernet devices. DHCP Client status Your DSL-2640U ADSL Router is configured, by default, to be a DHCP server.
Section 2 – Installation Device Installation The DSL-2640U connects two separate physical interfaces, an ADSL (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.
Section 2 – Installation Factory Reset Button The Router may be reset to the original factory default settings by using a ballpoint 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 off. 2. Turn on the power. 3. Wait for 5~8 seconds and then release the reset button. Remember that this will wipe out any settings stored in flash memory including user account information and LAN IP settings.
