1 Introduction
1.1 Overview
The Madge advanced Smart Wireless Access Point (advanced AP) enables IEEE 802.11b client
computers to access the resources on an Ethernet network. Because it supports IEEE 802.1x and RADIUS
(Remote Authentication Dial-In User Service) for user-based authentication and dynamic encryption key
distribution, it is suitable for enterprises that need strong data security and WISPs (Wireless Internet
Service Providers) that need accounting and billing support.
In Section 2, we describe the steps to install and configure a newly acquired advanced AP. Following the
steps, the advanced AP can be quickly set up to work. In Section 3, detailed explanations of each Web
management page are given for the user to understand how to fine-tune the settings of an advanced AP to
meet his or her specific needs. In addition to using Web-based Network Manager to configure an
advanced AP, the Windows-based Wireless Network Manager can also be used to configure and monitor
advanced APs. See the on-line help of Wireless Network Manager for more information.
1.2 Features
Configuration Reset. Resetting the configuration settings to factory-default values.
IEEE 802.11b:
Management:
Access point. Bridging packets between the wireless IEEE 802.11b network interface and the wired Ethernet LAN interface.
64-bit and 128-bit WEP (Wired Equivalent Privacy). For authentication and data encryption.
Enabling/disabling SSID broadcasts. The user can enable or disable the SSID (Service
Set ID) broadcast functionality for security reasons. When the SSID broadcast functionality is
disabled, a wireless client computer cannot connect to the advanced AP with a network name
(SSID) of “any”; the correct SSID has to be specified on client computers.
MAC-address-based access control. Blocking unauthorized wireless client computers
based on MAC (Media Access Control) addresses.
IEEE 802.1x/RADIUS. User authentication and dynamic encryption key distribution is
achieved by IEEE 802.1x Port-Based Network Access Control and RADIUS (Remote
Authentication Dial-In User Service).
Replaceable antennas. The factory-supplied antennas can be replaced with high-gain antennas for different purposes. NOTE: High gain antennas must be used in accordance with
local regulatory rules.
Windows-based Wireless Network Manager for configuring, monitoring, and
diagnosing the local computer and neighboring advanced APs. The management protocol is
MAC-based.
Web-based Network Manager for configuring and monitoring advanced APs. The
management protocol is HTTP (HyperText Transfer Protocol)-based.
SNMP. SNMP (Simple Network Management Protocol) MIB I, MIB II, IEEE 802.1d, IEEE
802.1x and Enterprise MIB are supported.
UPnP. The advanced AP responds to UPnP discovery messages so that a Windows XP user can locate the AP in My Network Places (the network neighborhood) and use a Web browser
to configure it.

Hardware Watchdog Timer. If the AP firmware enters an invalid state, the hardware watchdog
timer will detect this situation and restart the advanced AP. Accordingly, the advanced AP can
recover from certain error situations.

2 First-Time Installation and Configuration

2.1 Powering up the AP

To power the AP with the supplied power adapter:
1. Plug the power adapter to an AC socket.
2. Plug the connector of the power adapter to the power jack of the AP.
NOTE: This product is intended to be powered by a Listed Power Unit, marked “Class 2” or “LPS” and
output rated “5V DC, 1 A minimum” or equivalent statement.
Some advanced APs support Power Over Ethernet (POE). Visit the Madge web-site at www.madge.com
for more details.

2.2 Mounting the AP on a Wall

If required the AP can be mounted on a wall.
CAUTION: Before drilling into any surface check for hidden services such as electricity cables or water
pipes. If in doubt please consult a qualified engineer.
NOTE: The fastenings supplied with this product are intended for use in solid walls only.
To fix the AP to a solid wall proceed as follows:
1. Use the supplied template to determine the correct distance between the fastening screws.
2. Use a 6.5mm diameter drill to make a 25mm deep hole at each of the cross marks.
3. Insert the supplied “wall-plugs” into each hole.
4. Insert the supplied screws into the wall-plugs leaving approximately 3mm of thread proud of the
wall surface to allow the AP to be hung on the screws.
5. Hang the wireless AP on the screws.
Fig. 1. Mounting the AP on a wall.

2.3 Preparing for Configuration
For the user (or administrator) to configure an advanced AP, a managing computer with a Web browser is
needed. For first-time configuration of an advanced AP, an Ethernet network interface card (NIC) should
have been installed in the managing computer. For maintenance-configuration of a deployed advanced
AP, either a wireless computer or a wired computer can be employed as the managing computer.
NOTE: If you are using the browser, Opera, to configure an advanced AP, click the menu item File, click
Preferences..., click File types, and edit the MIME type, text/html, to add a file extension ".sht" so that
Opera can work properly with the Web management pages of the advanced AP.
Since the configuration/management protocol is HTTP-based, we have to make sure that the IP address
of the managing computer and the IP address of the managed advanced AP are in the same IP subnet (the default IP address of an AP is 192.168.0.1 and the default subnet mask is 255.255.255.0.)
NOTE: The AP’s factory default setting is to obtain its IP address automatically from a DHCP Server.
When the AP restarts it attempts to obtain an IP address repeatedly for approximately 75 seconds. If this
fails then it adopts the default IP address of 192.168.0.1.

2.3.1 Connecting the Managing Computer and the Advanced AP

To connect the Ethernet managing computer and the managed AP for first-time configuration, the user
has two choices as illustrated in Fig. 2.
Cross-over
Ethernet
cable
Managing Computer
Normal
Ethernet
cable
Ethernet
Hub/Switch
Normal
Ethernet
cable
Managed
AP
Fig. 2. Connecting a managing computer and an advanced AP via Ethernet.
The user can use either a cross-over Ethernet cable (we have included one in the package) or a switch/hub
with 2 normal Ethernet cables.
NOTE: One connector of the Ethernet cable must be plugged into the LAN/Config Ethernet socket of the
advanced AP for configuration.

2.3.2 Changing the TCP/IP Settings of the Managing Computer

Use the Windows Network Control Panel Applet to change the TCP/IP settings of the managing
computer, so that the IP address of the computer and the IP address of the advanced AP are in the same IP
subnet. Set the IP address of the computer to 192.168.0.xxx (the default IP address of an AP is
192.168.0.1) and the subnet mask to 255.255.255.0.
NOTE: For some versions of Windows, the computer needs to be restarted for the changes of TCP/IP
settings to take effect.

2.4 Configuring the Advanced AP

After the IP addressing issue is resolved, launch a Web browser on the managing computer. Then, go to
http://192.168.0.1” to access the Web-based Network Manager start page.
TIP: For maintenance configuration of an advanced AP, the advanced AP can be reached by its host
name using a Web browser. For example, if the advanced AP is named “advanced AP”, you can use the
URL “http://advanced AP” to access the Web-based Network Manager of the advanced AP.

2.4.1 Entering the User Name and Password

Before the start page is shown, you will be prompted to enter the user name and password to gain the
right to access the Web-based Network Manager. For first-time configuration, use the default user name
root” and default password “root”, respectively.
Fig. 3. Entering the user name and password.
NOTE: It is strongly recommended that the password be changed to other value for security reasons. On
the start page, click the General\Password link to change the value of the password (see Section 3.2.1 for
more information).
TIP: Since the start page shows the current settings and status of the advanced AP, it can be saved or
printed within the Web browser for future reference.

Fig. 4. The Start page.

2.4.2 Step 1: Configure TCP/IP Settings

Fig. 5. TCP/IP settings.
Go to the TCP/IP, Addressing section to configure IP address settings. The IP address can be manually set or automatically assigned by a DHCP server on the LAN. If you are manually setting the IP Address, Subnet Mask, and Default Gateway settings, set them appropriately, so that they comply with your LAN environment. In addition, you can specify the Host Name and Domain (DNS suffix) of the advanced AP. When you are finished, click Save at the bottom of this page, and then you are brought back to the start
page.
