Section 2 - Installation

802.11 Wireless LAN Configuration

All the 802.11 wireless LAN settings may be configured on a single page using the web-based manager. For basic wireless communication you

need to decide what channel to use and what SSID to assign. These two settings must be the same for any wireless workstations or other wireless

access point that communicate with the DSL-2740R through the wireless interface.

Security for wireless communication can be accomplished in a number of ways. The DSL-2740R supports WPA (Wi-Fi Protected Access), WPA2, and

mixed WPA/WPA2. Wireless access can also be controlled by selecting MAC addresses that are allowed to associate with the device. Please read the

section on Wireless Configuration.

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 being 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.

Section 2 - Installation

Username

This is the username used to log on to your ADSL service provider’s network. It is commonly in the form [email protected]. 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. However, if you are instructed to specify the modulation type used for the router, you may

choose among the numerous options available on the Modulation Type drop-down menu on the ADSL Configuration window (Advanced >

ADSL).

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 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.

Information you will need about the DSL-2740R

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.

LAN IP addresses for the DSL-2740R

This is the IP address you will enter into the Address field of your web browser to access the router’s configuration graphical user interface (GUI)

using a web browser. The default IP address is 192.168.1.1. This may be changed to suit any IP address scheme the user desires. This address will

be the base IP address used for DHCP service on the LAN when DHCP is enabled.

LAN Subnet Mask for the DSL-2740R

This is the subnet mask used by the DSL-2740R, and will be used throughout your LAN. The default subnet mask is 255.255.255.0. This can be

changed later.

Information you will need about your LAN or computer

Ethernet NIC

If your computer has an Ethernet NIC, you can connect the DSL-2740R to this Ethernet port using an Ethernet cable. You can also use the

Ethernet ports on the DSL-2740R to connect to other computers or Ethernet devices.

DHCP Client status

Your DSL-2740R 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-2740R 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 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-2740R Wireless ADSL Router.
