WBMR-G54 Wireless ADSL Router User Guide

operating can have a huge impact on its effectiveness. If you experience low signal strength or slow throughput,

consider positioning the Router in a different location. See the discussion below concerning the wireless environment

and location of the AP (WBMR-G54).

SSID and Channel

Wireless networks use an SSID (Service Set Identifier) as means of identifying a group of wireless devices, similar to a

domain or subnet. This allows wireless devices to roam from one AP to another and remain connected. Wireless devices

that wish to communicate with each other must use the same SSID. Several access points can be set up using the same

SSID so that wireless stations can move from one location to another without losing connection to the wireless network.

The embedded wireless access point of the Router operates in

Infrastructure

mode. It controls network access on the

wireless interface in its broadcast area. It will allow access to the wireless network to devices using the correct SSID

after a negotiation process takes place. By default, the WBMR-G54 broadcasts its SSID so that any wireless station in

range can learn the SSID and ask permission to associate with it. Many wireless adapters are able to survey or scan the

wireless environment for access points. An access point in Infrastructure mode allows wireless devices to survey that

network and select an access point with which to associate. You may disable SSID broadcasting in the web manager’s

wireless menu.

In addition, the AP can use different channels (frequency bands) to avoid unwanted overlap or interfere between control

zones of separate APs. Wireless nodes must use the same SSID and the same channel as the AP with which it wishes to

associate. However, because of the nature of the CSMA/CA (carrier sense multiple access with collision avoidance)

protocol, using the same channel on two different APs can contribute significantly to wireless congestion. If you are

using multiple APs on your network and are experiencing low throughput or significant transmission delay, carefully

consider how channels are assigned to the different APs.

Wireless Security

Various security options are available on the WBMR-G54 including open or WEP and WPA (including WPA-PSK).

Authentication may use an open system or a shared key. Read below for more information on configuring security for

the wireless interface.

Location and Wireless Operation

Many physical environmental factors can impact wireless networks. Radio waves are used to carry the encoded data

between devices. These radio transmissions can become degraded due to signal attenuation, multi-path distortion and

interference or noise. Attenuation simply means that the strength of the signal weakens with the distance it travels, even

if the transmission path is unobstructed. Multi-path distortion occurs when radio signals bounce off objects like walls,

ceilings, metal appliances, etc. This may cause a signal to be duplicated, with each separate yet identical signal arriving

at a receiver at different times. Interference and noise from electrical devices such as microwave ovens, fluorescent

lights, automobile engines and other radio emitting devices can cause signal degradation. With all this in mind, choose a

location for all your access points including the WBMR-G54.

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.

Wireless networking lets you access your network from nearly anywhere you want. However, the number of walls,

ceilings, or other objects that the wireless signals must pass through can limit signal range. Typical ranges vary

depending on the types of materials and background RF noise in your home or business. To range and signal strength,

use these basic guidelines:

1.

Keep the number of walls and ceilings to a minimum:

The signal emitted from Wireless LAN devices can

penetrate through ceilings and walls. However, each wall or ceiling can reduce the range of Wireless LAN

devices from 1 to 30M. Position your wireless devices so that the number of walls or ceilings obstructing the

signal path is minimized.

2.

Consider the direct line between access points and workstations:

A wall that is 0.5 meters thick, at a 45-

degree angle appears to be almost 1 meter thick. At a 2-degree angle, it is over 14 meters thick. Be careful to

position access points and client adapters so the signal can travel straight through (90º angle) a wall or ceiling

for better reception.

3.

Building Materials make a difference:

Buildings constructed using metal framing or doors can reduce

effective range of the device. If possible, position wireless devices so that their signal can pass through drywall

or open doorways, avoid positioning them so that their signal must pass through metallic materials. Poured

concrete walls are reinforced with steel while cinderblock walls generally have little or no structural steel.

4.

Position the antennas for best reception:

Play around with the antenna position to see if signal strength

improves. Some adapters or access points allow the user to judge the strength of the signal.

5.

Keep your product away (at least 1-2 meters) from electrical devices:

Position wireless devices away from

electrical devices that generate RF noise such as microwave ovens, monitors, electric motors, etc.

Hardware Installation

The WBMR-G54 Wireless ADSL Router maintains three separate interfaces, an Ethernet LAN, a wireless LAN and an

ADSL Internet (WAN) connection. Carefully consider the Router’s location suitable for connectivity for your Ethernet

and wireless devices. You must have a functioning broadband connection via a bridge device such as a Cable or ADSL

modem in order to use the Router’s WAN function.

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, direct sunlight 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 procedures.

The Router can be placed on a shelf, desktop, or other stable platform. If possible, 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 AC 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 device

settings will be restored to the factory default IP address

192.168.11.1

and the subnet mask is

255.255.255.0

, the default

management Username is “admin” and the default Password is “admin.”

Network Connections

Wired network connections are provided through the ADSL port and the four Ethernet ports 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-through 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 or hub for

another device, connect to any on

the other MDI-X ports (1x, 2x, etc.)

with a crossed cable.
