Chapter 1 Product Overview
1.1 Introduction
The 54Mbps wireless access point is a compact and high performance access point that is designed with support for high security features like WPA, IEEE 802.1x Authentication and 64-bit or 128-bit Wired Equivalent Privacy. The exclusive wireless LAN technology Wireless Pseudo VLAN further enhances security in wireless hotspot networks in isolating different users into their own VLANs. The access point is capable of operating in 5 different modes: Access Point Bridging, Access Point Client, Gateway, Wireless Routing Client and Wireless Ethernet Adapter; making it suitable for all kinds of wireless applications.
1.2 Features and Benefits
The access point has been designed for high performance and offers a rich suite of features, with which you should acquaint yourself to be able to exploit the access point’s full potential
Wireless Distribution System
This unique feature allows linking of several access points, virtually creating a larger wireless network infrastructure that allows desktops or laptops that are connected to the access point to share their network resources wirelessly.
Pseudo Virtual LAN
The unique Wireless Pseudo Virtual LAN technology is a feature that allows a wireless client or groups of wireless client to be segmented wirelessly into its individual workgroup or individual node thus enhancing the privacy of the wireless clients. This is especially useful in public hotspot deployment.
Secured Wireless Authentication
The access point supports the latest wireless security standard—WPA. The wireless users now enjoy the freedom of wireless roaming without worrying important data being exposed to outsiders. WPA has two different modes: WPA-PSK for SOHO users and WPA-EAP for Enterprise users. The access point supports WPA-EAP using IEEE 802.1x-based Extensible Authentication Protocol (EAP) for secure and centralized user-based authentication. The wireless clients are now able to authentication through a RADIUS server to the authorized network through highly secured authentication methods like EAP-TLS, EAP-TTLS, and EAP-PEAP.

Chapter 2 Hardware Installation
Smart Select
This feature will automatically scan and recommend the best channel that the access point can utilize.
Wireless Routing Client Capability
The Wireless Routing Client mode enables Internet Service Provider (ISP) or offices to send their data packet wirelessly and these network packets will be routed to a wired Local Area Network via the access point.
Wireless Ethernet Adapter
The Wireless Ethernet Adapter mode enables any computers with an Ethernet interface to be connected to the wireless LAN without the need to install any driver software. This is extremely useful for machines with limited driver support, e.g. Apple Macintosh machines and Linux machines.
Parallel Broadband
This unique feature allows bandwidth aggregation and fail-over redundancy capability when set to gateway mode which uses wireless distribution system to wirelessly link all associated access point gateway together.
Universal Configuration Software
The uConfig software allows users to get onto the web based configuration interface of the access point without the need to further manipulate the TCP/IP setup of the workstation.
Web-based Management Interface
Embedded with a HTTP server allows the configuration of the access point features via a user-friendly web-based management interface. In addition, firmware upgrade can be done through this interface as well.
IEEE 802.1x Authentication and WPA
The access point supports latest wireless security WPA using both Pre-Share Key and 802.1x EAP authentication. A wide range of IEEE 802.1x authentication methods like EAP-MD5, EAP-TLS, EAP-TTLS, and EAP-PEAP for strong mutual authentication and data encryption is supported.
Wireless Pseudo Virtual LAN
Allows the creation of wireless virtual nodes or workgroups for wireless clients to increase the privacy in a wireless LAN installation.
SNMP
For easy remote management and monitoring of the access point through standard SNMP software.
10
Chapter 2 Hardware Installation
STP
Spanning-Tree Protocol provides path redundancy while preventing undesirable loops in the network. It forces certain redundant data paths into a standby (blocked) state. If one network segment in the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree Protocol costs change, the spanning-tree algorithm reconfigures the spanning-tree topology and re-establishes the link by activating the standby path.
1.3 When to use which mode
The access point is unique in the sense that it may operate in up to 5 different complex modes in order to best suit any type of network application that you require.
This section presents a brief outline of the different network applications that can be accommodated through the different modes of the access point.
11
Chapter 2 Hardware Installation
1.3.1 The Access Point Mode
This is the default mode of the access point. The Access Point mode enables you to bridge wireless clients to the wired network infrastructure.
12
Chapter 2 Hardware Installation
1.3.2 The Access Point Client Mode
In Access Point Client mode, the access point acts as a wireless client that can operate wirelessly with another access point to perform transparent bridging between two Fast Ethernet networks.
13
Chapter 2 Hardware Installation
1.3.3 The Gateway Mode
Or more simply put: Broadband Internet sharing in a wireless network!
Since the access point supports several types of broadband connections, the first step in setting up the access point as a Broadband Internet Gateway is to identify the type of broadband Internet access you are subscribed to.
Static IP address
Use this type of connection if you have subscribed to a fixed IP address or to a range of fixed IP addresses from your Internet Service Provider.
Dynamic IP address
When powered using this type of connection, the access point requests for an IP address which will be automatically assigned to it by your Internet Service Provider.
This type of connection applies for instance, to:
Singapore Cable Vision subscribers
@HOME Cable Service users
14
Chapter 2 Hardware Installation
PPP over Ethernet (PPPoE)
Select this type of connection if you are using ADSL services in a country utilising standard PPP over Ethernet for authentication.
For instance: If you are in Germany which uses T-1 connection or If you are using SingNet Broadband or Pacific Internet Broadband in Singapore:
Singapore ADSL (Ethernet 512K)
This applies to ADSL subscribers in Singapore including SingTel Magix SuperSurf users.
Australia BPA Cable
This connection type is customised for Big Pond Cable Internet users in Australia.
PPTP
The Point-to-Point Tunneling Protocol (PPTP) mode enables the implementation of secure multi-protocol Virtual Private Networks (VPNs) through public networks.
15
Chapter 2 Hardware Installation
1.3.4 The Wireless Routing Client Mode
An application of this mode would be for the Ethernet port of the Wireless Routing Client to be used for connection with other devices on the network
while access to the Internet would be achieved through wireless communication with wireless ISP.
16
Chapter 2 Hardware Installation
1.3.5 The Wireless Ethernet Adapter Mode
Similarly to the Access Point Client mode, the access point used in this mode, is able to communicate wirelessly with another access point to perform transparent bridging between two networks.
However here, the Wireless Ethernet Adapter connects a single wired workstation only. No client software or drivers are required while using this mode.
1.3.6 The Wireless Bridge Link Mode
The Wireless Bridge Link mode allows point-to-point communication between different buildings. It enables you to bridge wireless clients that are kilometres apart ( eg. within 100 metres between two buildings ) while unifying the networks. In this scenario, you may configure two of the access point units to perform transparent bridging between two buildings.

Chapter 4 Common Configuration
Chapter 4 Common Configuration
This chapter illustrates the following features, which are available in ALL the operating modes of the access point, unless stated otherwise.
Management Port
WLAN Basic Setup
WLAN Security
STP Setup
SNMP
MAC Filtering
4.1 Management Port Setup
This section shows you how to customize the parameters of the access point to suit the needs of your network. It also explains how to make use of the built-in DHCP server of the access point.
Setting up your LAN
You can opt to adjust the default values of the access point and customize them to your network settings.
LAN SETUP
Click on Management Port from the CONFIGURATION menu.
In the Management Port Setup page, refer to the table below to replace the default settings of the access point with appropriate values to suit the needs of your network.
Click on Apply to save your new parameters.
27
Chapter 4 Common Configuration
This table describes the parameters that can be modified in the Management Port Setup page.
Parameters Description
IP Address
Network Mask
Management Gateway IP
The next two fields (DHCP Start IP Address and DHCP End IP Address) allow you to define the range of IP addresses from which the DHCP Server can assign an IP address to the LAN.
DHCP Start IP Address
DHCP End IP Address
DHCP Gateway IP
The LAN IP address of the access point is set by default to 192.168.168.1.
When the DHCP server of the AP is enabled (unless you set a different DHCP Gateway IP Address), this LAN IP Address would also be allocated as the Default Gateway of the DHCP client.
The Network Mask serves to identify the subnet in which the access point resides. The default network mask is 255.255.255.0.
(Optional) The Management Gateway here acts as the equivalent of the Default Gateway of a PC, to allow the access point to communicate with devices on different subnets. For instance, if you want to access the unit from the Internet or from a router on the LAN, you can set the IP address of the router as the Management Gateway IP.
The Management Gateway IP address of the access point is set to nil by default.
This is the first IP address that the DHCP server will assign. The value that you input here should belong to the same subnet as the access point. For example, if the IP address and network mask of the access point are 192.168.168.1 and
255.255.255.0 respectively, the DHCP Start IP Address should be 192.168.168.X, where X can take any value from 2 to 254. It is pre-set to 192.168.168.100.
This is the last IP address that the DHCP server can assign. It should also belong to the same subnet as the access point. For instance, if the IP address and network mask of the access point are 192.168.168.1 and 255.255.255.0 respectively, the DHCP End IP Address should be 192.168.168.X, where X can take any value from 2 to 254. It is pre-set as 192.168.168.254.
Though usually, the DHCP server also acts as the Default Gateway of the DHCP client, the access point gives you the option to define a different DHCP Gateway IP Address, which will be allocated as the Default Gateway of the DHCP client. The DHCP client will thus receive its dynamic IP address from the access point but will access to the Internet or to the other LAN through the Default Gateway defined by the DHCP Gateway IP Address.
For instance, when the unit is used in Access Point Client mode and connects to an Internet gateway, X, a PC wired to the ac cess point will be unable to obtain a dynamic IP address directly from X. But if you enable the DHCP server of the access point and set the X as the DHCP Gateway IP Address, the PC will then obtain its IP address from the access point and access the Internet through X.
28
Chapter 4 Common Configuration
Always use these DNS servers
Primary DNS IP Address
Secondary DNS IP Address
DHCP Server
Enable this checkbox if you want the access point to only use the DNS server(s) you have specified below.
Your ISP usually provides the IP address of the DNS server.
This optional field is reserved for the IP address of a secondary DNS server.
If you disable the DHCP server, you will need to manually configure the TCP/IP parameters of each PC in your network.
