Chapter 1
Introduction
This Chapter provides an overview of the Wireless Access Point's features
and capabilities.
Congratulations on the purchase of your new Wireless Access Point. The Wireless Access
Point links your 802.11g or 802.11b Wireless Stations to your wired LAN. The Wireless
stations and devices on the wired LAN are then on the same network, and can communicate
with each other without regard for whether they are connected to the network via a Wireless or
wired connection.
Figure 1: Wireless Access Point
The auto-sensing capability of the Wireless Access Point allows packet transmission up to
54Mbps for maximum throughput, or automatic speed reduction to lower speeds when the
environment does not permit maximum throughput.
Features of your Wireless Access Point
The Wireless Access Point incorporates many advanced features, carefully designed to provide
sophisticated functions while being easy to use.
•Standards Compliant. The Wireless Router complies with the IEEE802.11g (DSSS)
specifications for Wireless LANs.
•Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard
provides for backward compatibility with the 802.11b standard, so both 802.11b and
802.11g Wireless stations can be used simultaneously.
•108Mbps Wireless Connections. 108Mbps connections are available to compatible
clients.

•Bridge Mode Support. The Wireless Access Point can operate in Bridge Mode, con-
necting to another Access Point. Both PTP (Point to Point) and PTMP (Point to Multi-
Point) Bridge modes are supported.
And you can even use both Bridge Mode and Access Point Mode simultaneously!
•Client/Repeater Access Point. The Wireless Access Point can operate as a Client or
Repeater Access Point, sending all traffic received to another Access Point.
•Simple Configuration. If the default settings are unsuitable, they can be changed
quickly and easily.
•DHCP Client Support. Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. The Wireless Access Point can act as a
DHCP Client, and obtain an IP address and related information from your existing DHPC
Server.
•Upgradeable Firmware. Firmware is stored in a flash memory and can be upgraded
easily, using only your Web Browser.
•PoE Support. You can use PoE (Power over Ethernet) to provide power to the Wireless
Access Point, so only a single cable connection is required.
Security Features
•Security Profiles. For maximum flexibility, wireless security settings are stored in
Security Profiles. Up to 8 Security profiles can be defined, and up to 4 used as any time.
•Multiple SSIDs.Because each Security Profile has it own SSID, and up to 4 Security
Profiles can be active simultaneously, multiple SSIDs are supported. Different clients can
connect to the Wireless Access Point using different SSIDs, with different security set-
tings.
•Multiple SSID Isolation.If desired, PCs and devices connecting using different SSIDs
can be isolated from each other.
•VLAN Support. The 802.1Q VLAN standard is supported, allowing traffic from differ-
ent sources to be segmented. Combined with the multiple SSID feature, this provides a
powerful tool to control access to your LAN.
•WEP support. Support for WEP (Wired Equivalent Privacy) is included. Both 64 Bit
and 128 Bit keys are supported.
•WPA support. Support for WPA is included. WPA is more secure than WEP, and
should be used if possible. Both TKIP and AES encryption methods are supported.
•802.1x Support. Support for 802.1x mode is included, providing for the industrial-
strength wireless security of 802.1x authentication and authorization.
•Radius Client Support. The Wireless Access Point can login to your existing Radius
Server (as a Radius client).
•Radius MAC Authentication. You can centralize the checking of Wireless Station
MAC addresses by using a Radius Server.
•Rogue AP Detection.The Wireless Access Point can detect unauthorized (Rouge)
Access Points on your LAN.
•Access Control. The Access Control feature can check the MAC address of Wireless
clients to ensure that only trusted Wireless Stations can use the Wireless Access Point to
gain access to your LAN.
•Password - protected Configuration. Optional password protection is provided to
prevent unauthorized users from modifying the configuration data and settings.

Advanced Features
•Auto Configuration. The Wireless Access Point can perform self-configuration by
copying the configuration data from another Access Point. This feature is enabled by de-
fault.
•Auto Update. The Wireless Access Point can automatically update its firmware, by
downloading and installing new firmware from your FTP server.
•Command Line Interface. If desired, the command line interface (CLI) can be used for
configuration. This provides the possibility of creating scripts to perform common con-
figuration changes.
•NetBIOS & WINS Support. Support for both NetBIOS broadcast and WINS (Win-
dows Internet Naming Service) allows the Wireless Access Point to easily fit into your
existing Windows network.
•Radius Accounting Support. If you have a Radius Server, you can use it to provide
accounting data on Wireless clients.
•Syslog Support. If you have a Syslog Server, the Wireless Access Point can send its log
data to your Syslog Server.
•SNMP Support. SNMP (Simple Network Management Protocol) is supported, allowing
you to use a SNMP program to manage the Wireless Access Point.
•UAM Support. The Wireless Access Point supports UAM (Universal Access Method),
making it suitable for use in Internet cafes and other sites where user access time must be
accounted for.
•WDS Support. Support for WDS (Wireless Distribution System) allows the Wireless
Access Point to act as a Wireless Bridge. Both Point-to-Point and Multi-Point Bridge
modes are supported.

Antenna One antenna (aerial) is supplied. Best results are usually obtained with
the antenna in a vertical position.

Reset Button This button has two (2) functions:
•Reboot. When pressed and released, the Wireless Access Point
will reboot (restart).
•Reset to Factory Defaults. This button can also be used to clear
ALL data and restore ALL settings to the factory default values.
To Clear All Data and restore the factory default values:
1. Hold the Reset Button down until the Status (Red) LED blinks
TWICE, usually more than 5 seconds.
2. Release the Reset Button.
The factory default configuration has now been restored, and the
Access Point is ready for use.
Ethernet Use a standard LAN cable (RJ45 connectors) to connect this port to a
10BaseT or 100BaseT hub on your LAN.
Power port Connect the supplied power adapter here.

Chapter 2
Installation
This Chapter covers the physical installation of the Wireless Access Point.
Requirements
Requirements:
•TCP/IP network
•Ethernet cable with RJ-45 connectors
•Installed Wireless network adapter for each PC that will be wirelessly connected to the
network
Procedure
1. Select a suitable location for the installation of your Wireless Access Point. To maximize
reliability and performance, follow these guidelines:
•Use an elevated location, such as wall mounted or on the top of a cubicle.
•Place the Wireless Access Point near the center of your wireless coverage area.
•If possible, ensure there are no thick walls or metal shielding between the Wireless
Access Point and Wireless stations. Under ideal conditions, the Wireless Access Point
has a range of around 150 meters (450 feet). The range is reduced, and transmission
speed is lower, if there are any obstructions between Wireless devices.
