portal suitable for most small to medium sized offices. The C54APRA2+ / C54APRB2+ advantages include:
•PPP (Point-to-Point Protocol) Security – The C54APRA2+ / C54APRB2+ 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 C54APRA2+ / C54APRB2+ 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 C54APRA2+ / C54APRB2+ 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 C54APRA2+ / C54APRB2+ 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 C54APRA2+ / C54APRB2+ 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 C54APRA2+ / C54APRB2+ 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 C54APRA2+ / C54APRB2+ uses a web-based graphical user interface program for

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
C54APRA2+ / C54APRB2+ 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 use for data
transmission. The embedded wireless access point 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
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 (C54APRA2+ / C54APRB2+).
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 C54APRA2+ / C54APRB2+ 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 C54APRA2+ / C54APRB2+ 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.

C54APRA2+ / C54APRB2+ Wireless ADSL Router User Guide

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 C54APRA2+ / C54APRB2+.
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 C54APRA2+ / C54APRB2+ 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
WARNING!
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. Switch the power on by positioning the power switch in the On position.
3. 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.
4. 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 192.168.1.1 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. 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.
Computer to Router Connection
You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a PC using the
Ethernet cable provided.

Basic Router Configuration
The first time you set up the Router it is recommended that you configure the WAN connection using a single computer
making sure that both the computer and the Router are not connected to the LAN. Once the WAN connection is
functioning properly, you may continue to make changes to Router configuration including IP settings and DHCP setup.
This chapter is concerned with using your computer to configure the WAN connection. The following chapter describes
the various windows used to configure and monitor the Router including how to change IP settings and DHCP server
setup.
Configuration Summary
1. Connect to the Router To configure the WAN connection used by the Router it is first necessary to
communicate with the Router through its management interface, which is HTML-based and can be accessed
using a web browser. To access the management software your computer must be able to “see” the Router.
Your computer can see the Router if it is in the same “neighborhood” or subnet as the Router. This is
accomplished by making sure your computer has IP settings that place it in the same subnet as the Router. The
easiest way to make sure your computer has the correct IP settings is to configure it to use the DHCP server in
the Router. The next section describes how to change the IP configuration for a computer running a Windows
operating system to be a DHCP client.
2. Configure the WAN Connection Once you are able to access the configuration software you can proceed to
change the settings required to establish the ADSL connection and connect to the service provider’s network.
There are different methods used to establish the connection to the service provider’s network and ultimately to
the Internet. You should know what Encapsulation and connection type you are required to use for your ADSL
service. It is also possible that you must change the PVC settings used for the ADSL connection. Your service
provider should provide all the information you need to configure the WAN connection.
Configuring IP Settings on Your Computer
In order to configure your system to receive IP settings from the Router your computer must first have the TCP/IP
protocol installed. If you have an Ethernet port on your computer, it probably already has TCP/IP protocol installed. If
you are using Windows XP the TCP/IP is enabled by default for standard installations. Instructions for configuring your
computer to receive IP settings from the Router are provided in Appendix B on page 83.
For computers running non-Windows operating systems, follow the instructions for your OS that configure the system
to receive an IP address from the Router, that is, configure the system to be a DHCP client.
Note
If you are not sure how to configure your Windows computer to be a DHCP client, see
Configuring IP Settings on Your Computer in Appendix B.

Access the Configuration Manager
In order to make sure your computer’s IP settings allow it to communicate with the Router, it is advisable to configure
your system be a DHCP client – that is, it will get IP settings from the Router. Appendix B describes how to configure
different Windows operating systems to “Obtain IP settings automatically”.
Note
Be sure that the web browser on your computer is not configured to use a proxy server in the
Internet settings. In Windows Internet Explorer, you can check if a proxy server is enabled using the
following procedure:
1. In Windows, click on the Start button and choose Control Panel.
2. In the Control Panel window, click on the Network and Internet Options icon.
3. In the Network and Internet Connections window, click the Internet Options icon.
4. In the Internet Properties window, click on the Connections tab and click on the LAN Settings
button
5. Verify that the “Use a proxy server for your LAN (These settings will not apply to dial-up or VPN
connections).” option is NOT checked. If it is checked, click in the checked box to deselect the
option and click OK.
Alternatively, you can access this Internet Options menu using the Tools pull-down menu in
Internet Explorer.
Login to Home Page
To use the web-based management software, launch a suitable web browser and direct it to the IP address of the Router.
Type in http:// followed by the default IP address, 192.168.1.1 in the address bar of the browser. The URL in the
address bar should read: http://192.168.1.1.
A dialog box prompts for the User Name and Password. Type in the default User Name “admin,” and the default
Password “admin” then click the OK button to access the web-based manager.
Enter Password
You should change the web-based manager access user name and password once you have verified that a connection
can be established. The user name and password allows any PC within the same subnet as the Router to access the web-
based manger.
Note
The user name and password used to access the web-based manager is NOT the same as the
ADSL account user name and password needed for PPPoE/PPPoA connections to access the
Internet.
