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 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.

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/PPoA (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) used in conjunction with the VPI to identify the data path

Information you will need about your LAN or computer

:

Ethernet NIC

If your computer has an Ethernet NIC, you can connect the DSL-2750U to this Ethernet port using an Ethernet cable. You can also use the Ethernet

ports on the DSL-2750U to connect to other computer or Ethernet devices.

DHCP Client status

Your DSL-2750U 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-2750U 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 your collect and 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-2750U ADSL Router.
