Introduction

This section provides a brief description of the Router, its associated technologies, and a list of Router features.

Router Description and Operation

The WBMR-G54 Wireless ADSL Router is designed to provide connectivity for your private Ethernet LAN, and

802.11g/802.11b wireless LAN to the Internet via an ADSL connection.

The Router is easy to install and use. Standard Ethernet ports are used to connect to computer or other Ethernet devices.

The 802.11g wireless interface provides connectivity to 802.11g or 802.11b wireless devices.

802.11g Wireless

The embedded 802.11g wireless access point provides Internet access and connectivity to the Ethernet for 802.11g and

802.11b wireless workstations. IEEE 802.11g is fully compatible with IEEE 802.11b wireless devices. The 802.11g

standard supports data transfer rates of up to 54 Mbps. The wireless Router supports 64-bit and 128-bit WEP

encryption.

ADSL

Asymmetric Digital Subscriber Line (ADSL) is a broadband network technology that utilizes standard twisted-pair

copper wire telephone lines to enable broadband high-speed digital data transmission and bandwidth hungry

applications for business and residential customers.

ADSL routers and modems provide faster downloads and more reliable connectivity to the user without loss of quality

or disruption of voice/fax telephone capabilities.

ADSL service operates at speeds of up to 8 Mbps downstream and up to 640 Kbps upstream. A secure dedicated point-

to-point connection is established between the user and the central office of the service provider.

Router Features

The WBMR-G54 ADSL Router utilizes the latest ADSL enhancements to provide a reliable Internet portal suitable for

most small to medium sized offices. WBMR-G54 advantages include:

•

PPP (Point-to-Point Protocol) Security –

The WBMR-G54 ADSL Router supports PAP (Password

Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections.

•

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.

•

Network Address Translation (NAT) –

For small office environments, the WBMR-G54 allows multiple users on

the LAN to access the Internet concurrently through a single Internet account. This provides Internet access to

everyone in the office for the price of a single user.

NAT improves network security in effect by hiding the private network behind one global and visible IP address.

NAT address mapping can also be used to link two IP domains via a LAN-to-LAN connection.

•

TCP/IP (Transfer Control Protocol/Internet Protocol) –

The WBMR-G54 supports TCP/IP protocol, the

language used for the Internet. It is compatible with access servers manufactured by major vendors.

•

RIP-1/RIP-2 –

The WBMR-G54 supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions

lets the Router to communicate with all RIP enabled devices.

•

Static Routing –

This allows you to select a data path to a particular network destination that will remain in the

routing table and never “age out”. If you wish to define a specific route that will always be used for data traffic

from your LAN to a specific destination within your LAN (for example to another router or a server) or outside

your network (to an ISP defined default gateway for instance).

•

Default Routing –

This allows you to choose a default path for incoming data packets for which the destination

address is unknown. This is particularly useful when/if the Router functions as the sole connection to the Internet.

•

ATM (Asynchronous Transfer Mode) –

The WBMR-G54 supports Bridged Ethernet over ATM

(RFC1483), IP

over ATM (RFC1577) and PPP over ATM

(RFC 2364)

.

•

Precise ATM Traffic Shaping –

Traffic shaping is a method of controlling the flow rate of ATM data cells. This

function helps to establish the Quality of Service for ATM data transfer.

•

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 WBMR-G54 incorporates SNMP (Simple Network Management Protocol)

support for web-based management and text-based network management via an RS-232 or Telnet connection.

•

Telnet Connection –

The Telnet enables a network manager to access the Router’s management software

remotely.

•

Easy Installation

–

The WBMR-G54 uses a web-based graphical user interface program for convenient

management access and easy set up. Any common web browser software can be used to manage the Router.

Front Panel Display

Place the Router in a location that permits an easy view of the LED indicators on the front panel.

The LED indicators on the front panel include

Power

,

Status

,

ADSL

,

WLAN

, and

LAN

. The

ADSL

,

WLAN

, and

LAN

indicators monitor link status and activity (

Link/Act

).

Power

Steady green light indicates the unit is powered on. When the device is

powered off this remains dark.

Status

Lights steady green during power on self-test (POST). Once the connection

status has been settled, the light will blink green. If the indicator lights

steady green after the POST, the system has failed and the device should be

rebooted.

ADSL (Link/Act)

Steady green light indicates a valid ADSL connection. This will light after the

ADSL negotiation process has been settled. A blinking green light indicates

activity on the WAN (ADSL) interface.

WLAN (Link/Act)

Steady green light indicates a wireless connection. A blinking green light

indicates activity on the WLAN interface

LAN (Link/Act)

A solid green light indicates a valid link on startup. These lights blink when

there is activity currently passing through the Ethernet port.

different voltage rating will

damage the device and void

the warranty of this product.

Setting Up a Wireless Network

In order to get the best performance from the wireless component of the Router, you should have some basic

understanding of how wireless networks operate. Wireless networking is a relatively new technology and there are more

factors to consider when setting up or designing a wireless network than designing a wired network. If you are setting

up a wireless network, especially if you are using multiple access points and/or covering a large area, good planning

from the outset can ensure the best possible reliability, performance, coverage and effective security.

Radio

Wireless local network (as called WI-FI) devices such as notebook computers and wireless access points use

electromagnetic waves within a broad, unlicensed range of the radio spectrum (between 2.4GHz and 2.5GHz) to

transmit and receive radio signals. A wireless access point (AP) becomes a base station for the wireless nodes (notebook

computer for example) in its broadcast range. Often a wireless access point such as the AP embedded in the WBMR-

G54, will also provide a connection to a wired network - usually Ethernet - and ultimately an Internet connection. The

IEEE 802.11 standard precisely defines the encoding techniques used to digitally used for data transmission. The

WBMR-G54 can be used by IEEE 802.11g and 802.11b devices. These two standards are compatible but use different

algorithms for data transmission.

802.11g uses a method called Orthogonal Frequency Division Multiplexing (OFDM) for transmitting data at higher data

rates. OFDM is a more efficient encoding method than Direct Sequence Spread Spectrum (DSSS) transmission, the

method used by 802.11b devices. However, in order to support different data transmission rates while also be

compatible with 802.11b, 802.11g uses a combination of OFDM and DSSS when 802.11b devices are present.

Range

An access point will send and receive signals within a limited range. Also, be aware that the radio signals are emitted in

all directions giving the access point a spherical operating range. The physical environment in which the AP is
