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 Wireless Stations to your wired LAN. With the Wireless Access Point, you
can select either 2.4 GHz or 5 GHz radio bands, which provides the flexibility to manage a
graceful transition from networks. 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.

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 Access Point complies with the IEEE802.11g and
IEEE802.11n draft 2.0 specifications for Wireless LANs.
Supports 11n Wireless Stations. The 802.11n Draft standard provides for backward
compatibility with the 802.11b standard, so 802.11n, 802.11a, 802.11b and 802.11g
Wireless stations can be used simultaneously. The Wireless Access Point supports both
the 2.4GHz and 5.0GHz (802.11a) bands.
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
Virtual APs. For maximum flexibility, wireless security settings are stored in Virtual AP.
Up to 16 Virtual APs can be defined and used as any time.
Multiple BSSIDs.Because each Virtual AP has it own SSID and beacon, and up to 16
Virtual APs can be active simultaneously, multiple SSIDs are supported. Different clients
can connect to the Wireless Access Point using different SSIDs, with different security
settings.
Virtual APs Isolation.If desired, PCs and devices connecting to different Virtual APs
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. The 64 Bit,
128 Bit and 152 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
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 config-
uration changes.
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.
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.

Introduction

SNMP Support. SNMP (Simple Network Management Protocol) is supported, allowing
you to use a SNMP program to manage the Wireless Access Point. When stores the con-
figuration, will not affect the operation of SNMP and CLI.
VPN Pass – through. Do not affect related application operation (such as ICMP, FTP,
HTTP, Etc.) when in IP network, and support VPN Pass - through function.

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 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.
Console port This port allows root access to the router via a dumb terminal interface.
LAN/PoE Use a standard LAN cable (RJ45 connectors) to connect this port to a
10/100/1000BaseT hub/switch on your LAN.
Power port Connect the supplied power adapter (12V) here.
