Chapter 2 QUICK INSTALLATION
System Requirements
Suggested Specifications for Wireless LAN Access Point installation:
•A PC, Notebook or Macintosh Computer with installed 802.11b/g wireless LAN adapter
•An Ethernet router or hub
•Ethernet patch cable
Planning Your Network Environment
You can build your network environment as the picture above. After you set up the access point, you can
surf the internet by wireless from your PC, PDA and Notebook which built-in wireless module.

Hardware Installation
Follow the steps below when installing your Access Point(s).
Before you begin, please keep the following in mind when placing your Access Point(s).
9Select a suitable location to install the Access Point. Assure that the location is away from
any interfering radio signals from devices such as microwave ovens, garage door openers,
vacuum cleaning devices, etc. Please also operate the Access Point in a cool dry place, away
from direct sunlight.
9Position the Access Point appropriately. Signal strength is greatly dependent on your well
placed Access Point. Generally, a centralized area with 360° clear line of sight is the best
location with the antenna in a high position to allow optimal propagation of the signal. The
location of the Access Point greatly influences the signal reception.
Installing the Access Point
Step 1 Turn off all the hardware devices in your network.
Step 2 Connect the Ethernet cable of your router/hub to the LAN port of the Access Point.
Step 3 Plug the power adapter cord into the router’s power jack and then plug the power adapter into a
power outlet.
Step 4 Turn on all the hardware devices in your network. After verifying all the connections, proceed to

Wireless Basic Settings
The Access Point will automatically detect and display your wireless settings. Changes of these settings will
influence your wireless connection and performance.
SSID
ESSID (or SSID as it is usually referred to) is the network name of the Access Point in the wireless
network. You should set the same SSID name for all your wireless-equipped devices to allow dynamic
clients to easily roam among them. The SSID name can be up to 32 characters in length and is case
sensitive (i.e. upper case letters “A~Z” and lower case “a~z” are unique).
Channel Number
Please choose the channel for best performance. Normally, no change is needed.
Transmit Rate
Select the desired data rate. The range is from 1 to 54Mbps and the default rate is set to “Auto”.
802.11g Only Mode
Enabled -- No Wireless-B clients will be allowed on the network.
Disabled – Both Wireless-G and Wireless-B clients will be allowed on the network. (Default setting)
Hidden ESSID
This setting enables you to hide ESSID name, which is needed by clients in order to connect to the
Access Point. The default value is “Disable”. In this setting, all users are able to read your AP’s
SSID name.

Wireless Security Setting
Use this feature to set up the security types for the Access Point. Five security types are available: Open
System, Shared Key, 802.1x, WPA and WPA Pre-Shared Key.
* Open system
Allows any device to connect to the network, assuming the device’s SSID matches the access point’s
SSID.
* Shared Key
Only those computers that have the correct authentication key can join the network.
Key Length choice
Disable - No encryption will be applied.
64-bit -enter 5 hexadecimal digits.
128-bit - enter 13 hexadecimal digits.

* 802.1x
802.1x is IEEE standard for EAP encapsulation over wired or wireless Ethernet. 802.1x uses three
terms that you need to know. The user or client that wants to be authenticated is called a supplicant.
The actual server doing the authentication, typically a RADIUS server, is called the authentication
server. And the device in between, such as a wireless access point, is called the authenticator. One of
the key points of 802.1x is that the authenticator can be simple and dumb - all of the brains have to be
in the supplicant and the authentication server. This makes 802.1x ideal for wireless access points,
which are typically small and have little memory and processing power.
RADIUD Server IP – Assign an IP address for the RADIUS Server.
RADIUS Port – Enter a value within the range 1~65536 for port.
RADIUS Secret – Enter a password up to 32 ASCII characters (uppercase “A~Z”, lowercase “a~z”, or
numeric “0~9”) in length.
RADIUS Re-key – Lets you enable or disable the RADIUS Re-Key function.

* WPA (Wi-Fi Protected Access)
If you have used Wi-Fi for a while, you may be familiar with 802.1x Authentication Protocol, which
allows users to authenticate the wireless network via RADIUS server. The 802.1x Authentication
Protocol is an option in standard Wi-Fi but a must for WPA.
RADIUD Server IP – Assign an IP address for the RADIUS Server.
RADIUS Port – Enter a value within the range 1~65536 for port.
RADIUS Secret – Enter a password up to 32 ASCII characters (uppercase “A~Z”, lowercase “a~z”, or
numeric “0~9”) in length.
RADIUS Re-key – Lets you enable or disable the RADIUS Re-Key function.
Cipher Algorithms – Two options you can choose: TKIP and AES settings.
Group Re-key - Lets you enable or disable the RADIUS Re-Key function.

* WPA Pre-Shared Key
Traditional WEP had an inconvenient method to change encrypted keys. Even when you changed the
encrypted keys; you still can not select all APs and wireless LAN adapter while you are changing
encrypted keys.
The manual re-keying which is necessary with WEP is a tedious manual process and is completely
impractical for large organizations. After all, the instant you re-key an access point, none of the clients
will be able to access it until they too are re-keyed. But with WPA, the re-keying of global encryption
keys is all that is necessary. In the case of unicast traffic, the encryption key is changed after every
frame using Temporary Key Integrity Protocol (TKIP). This protocol allows key changes to occur on a
frame-by-frame basis and to be automatically synchronized between the access point and the
wireless client. Global re-keying works by advertising the new keys to the wireless clients.
Cipher Algorithms – Two options you can choose: TKIP and AES settings.
Group Re-key - Two options: Enabled or Disabled.
Pre-Shared key - Enter a password up to 63 ASCII characters (uppercase “A~Z”, lowercase “a~z”, or
numeric “0~9”) in length.

WDS Settings
The WDS function allows several of the access points to compose a wide Wireless LAN network. Please
note all APs must be set to use the same channel and the SSID of all participating APs must also be the
same.
WDS technologies between AP manufacturers vary widely, so you may not be able to establish WDS
between APs from different manufacturers.

Wireless Access Control
You may specify users based on their MAC addresses that are authorized to connect to the AP. Only
computers listed in the table can connect to AP when this function is enabled.

TCP/IP Settings
You may set up IP parameters for APs through TCP/IP setting screen.
DHCP Mode
Three (3) options are available: “Disabled”, “Client Enabled” , “Server Enabled”. The default value is
“Server Enabled”.
If you want to obtain IP addresses from a DHCP server, select “Client Enabled”. To use an AP as a
DHCP server and assign a dynamic IP address automatically on the network, select “Server
Enabled”.
IP Address
Assign an IP address to the AP with this option. The default IP address is 192.168.1.1. Please make
sure the assigned IP address is exclusive for the AP.
Subnet Mask
Assign a Subnet Mask for an AP. The default Subnet Mask is 255.255.255.0.
Default Gateway
Enter the IP address for the default router. The default gateway is 192.168.1.1.
DHCP Client Range
When “Server Enabled” is selected, please enter the range of your IP addresses.
