1 1. Introduction
1.1 Overview
The 802.11A/G ACCESS POINT is an access-point based on IEEE 802.11a/g
based 2.4-GHz and 5-GHz radio technology. It contains an 802.11a/g and
three half/full-duplex 10/100 LAN interfaces. The 802.11A/G ACCESS POINT
features a total of 6 wireless modes: Access Point, WDS Repeater, WDS
Bridge, Client Infrastructure, Client Adhoc and WISP Router.
Since the 802.11g shares the same 2.4GHz radio band with the 802.11b
technology, it can inter-operate with existing 802.11b (up to 11Mbps) devices.
Therefore, you can reserve your existing investment in 802.11b client cards,
and migrate to the high-speed 802.11g standard as your needs grow.
To address growing security concerns in a wireless LAN environment, different
levels of security can be enabled in the 802.11A/G ACCESS POINT:
 To disable SSID broadcast to restrict association to only those client
stations that are already pre-configured with the correct SSID
 To enable WEP (Wireless Encryption Protocol) 64, 128, or 152-bit
encryption to protect the privacy of your data.
 Support of Access List Control to allow you to grant/deny access to/from
specified wireless stations
 Provisioning of centralized authentication through Radius Server.
 WPA-PSK (Wi-Fi Protected Access, Pre-Shared Key) for home users to
provide authentication, data integrity, and data privacy.
 WPA (Wi-Fi Protected Access), WPA2 (Wi-Fi Protected Access 2),
WPA2-PSK (Wi-Fi Protected Access 2, Pre-Shared Key) works with a
RADIUS server to provide stronger authentication as well as data integrity
and privacy.

1.3 Wireless Operation Modes
A group of wireless stations communicating with each other is called a Basic
Service Set (BSS) and is identified by a unique SSID.
When an 802.11A/G ACCESS POINT is used, it can be configured to operate
in the following network configurations.

8
1.3.1 Access Point Mode
When configured in the Access Point mode, the 802.11A/G ACCESS POINT
allows a group of wireless stations to communicate with each other through it.
Such a network is called an Infrastructure BSS.
The 802.11A/G ACCESS POINT further provides bridging functions between
the wireless network and the wired LAN network.
When multiple access points are connected to the same LAN segment,
stations can roam from one 802.11A/G ACCESS POINT to another without
losing their connections, as long as they are using the same SSID. See the
diagram below.

1.3.7 Gateway (AP-Router) Mode
In Gateway (AP-Router) Mode, 802.11A/G ACCESS POINT is connected
to ISP and several stations are connected to 802.11A/G ACCESS POINT
wirelessly. With IP sharing function, the stations can share Internet connection
via 802.11A/G ACCESS POINT. Moreover, more than one ISP can be set for
the available connection. Therefore, if the current Internet connection is broken
another ISP will be switched automatically.
1.4 Set up the device
The 802.11A/G ACCESS POINT can be managed remotely by a PC through
either the wired or wireless network. To do this, the 802.11A/G ACCESS
POINT must first be assigned an IP address, which can be done using one of
the following two methods.
Station

1.4.1 STATIC IP
The default IP address of the LAN interface of an 802.11A/G ACCESS POINT
is a private IP address of 192.168.1.1, and a network mask of 255.255.255.0.
This means IP addresses of other devices on the LAN should be in the range
of 192.168.1.2 to 192.168.1.254.
This IP address can be modified to either a different address in this same
subnet or to an address in a different subnet, depending on the existing
network settings (if there is any) or user’s preferences.
1.4.2 AUTOMATIC IP
The 802.11A/G ACCESS POINT can also be configured to “obtain” an IP
address automatically from a DHCP server on the network. This address is
called “dynamic” because it is only dynamically assigned to the device, which
may change depends on the IP assignment policy used by the DHCP server
on the network. Since the IP address in this case may change from time to
time, this method is not recommended - unless the user uses UPnP or other
management tools that do not depend on a fixed IP address.

2 2. Install the 802.11 A/G
Access Point
This section describes the installation procedure for the 802.11A/G ACCESS
POINT. It starts with a summary of the content of the package you have
purchased, followed by steps of how to power up and connect the 802.11A/G
ACCESS POINT. Finally, this section explains how to configure a Windows PC
to communicate with the 802.11A/G ACCESS POINT.
2.1 What’s in the box?
The 802.11A/G ACCESS POINT package contains the following items:
 One 802.11A/G ACCESS POINT
 One 5V DC power adapter with a barrel connector
 One CD of the 802.11A/G ACCESS POINT User Guide
2.2 Connect the cables
The Back Panel of the 802.11A/G ACCESS POINT appears as follows:
LAN
RESET
POWER
Follow these steps to install your 802.11A/G ACCESS POINT:
Step 1. Connect a LAN hub to the LAN port on the 802.11A/G ACCESS
POINT using the supplied LAN cable.
Step 2. Connect the power adapter to an electrical outlet and the 802.11A/G
ACCESS POINT.

14
You can reset the Access Point’s Settings to factory defaults by
pushing a paperclip in the RESET hole. Push and hold until the
lights at the front of the Access Point are off.
2.3 Configuration steps
This section describes configuration required for the 802.11A/G ACCESS
POINT before it can work properly in your network.
First, it is assumed that in your LAN environment, a separate DHCP server will
be available for assigning dynamic (and often private) IP addresses to
requesting DHCP clients.
Additionally, since you need to perform various configuration changes to the
802.11A/G ACCESS POINT, including the SSID, Channel number, the WEP
key, …, etc., it is necessary to associate a fixed IP address with the 802.11A/G
ACCESS POINT, which is why the 802.11A/G ACCESS POINT will be shipped
with a factory default private IP address of 192.168.1.1 (and a network mask of
255.255.255.0).
Therefore, during the system installation time, you need to build an isolated
environment with the 802.11A/G ACCESS POINT and a PC, and then perform
the following steps:
Step 1. Manually change the IP address of the PC to become 192.168.1.3.
Step 2. Connect the PC to the 802.11A/G ACCESS POINT and change its
configuration to a static IP address based on your network
environment. For example, if there is a DHCP server that assigns IP
addresses from the range 192.168.23.10 - 192.168.23.254 to DHCP
client devices, it can reserve 192.168.23.10 for the 802.11A/G
ACCESS POINT and then the address pool with the DHCP server
becomes 192.168.23.11 – 192.168.23.254.
If there is no DHCP server on your network environment, you just
have to make sure that there is no machine in the environment has
the same IP address as another machine.
Please note that after you change the IP address of the ACCESS

15
POINT, the PC client may not be able to reach the ACCESS POINT.
This is because they may no longer belong to the same IP network
address space.
Step 3. Change the setting of the PC back to “obtain IP addresses
dynamically”.
Now you can put the 802.11A/G ACCESS POINT and the PC to your
network where the DHCP server is connected. From then on, any
wireless client configured to “obtain IP addresses dynamically” will
work with the AP, with each other, and with devices on the wired LAN
network.
2.4 Set up a wireless client as a DHCP client
The following will give detailed steps of how to configure a PC or a wireless
client to “obtain IP addresses automatically”.
In the case of using a LAN attached PC, the PC must have an Ethernet
interface installed properly, be connected to the 802.11A/G ACCESS POINT
either directly or through an external LAN switch, and have TCP/IP installed
and configured to obtain an IP address automatically from a DHCP server in
the network.
In the case of using a wireless client, the client must also have an 802.11a/b/g
wireless interface installed properly, be physically within the radio range of the
802.11A/G ACCESS POINT, and have TCP/IP installed and configured to
obtain an IP address automatically from a DHCP server in the network.
Then perform the following steps for either of the cases above. To configure
types of workstations other than Windows 95/98/NT/2000, please consult the
manufacturer’s documentation.
Step 1. From the Win95/98/2000 Start Button, select Settings, then Control
Panel. The Win95/98/2000 Control Panel displays.
Step 2. Double-click on the Network icon.
Step 3. Check your list of Network Components in the Network window
Configuration tab. If TCP/IP has already been installed, go to Step 8.

16
Otherwise, select Add to install it now.
Step 4. In the new Network Component Type window, select Protocol. In the
new Select Network Protocol window, select Microsoft in the
Manufacturers area.
Step 5. In the Network Protocols area of the same window, select TCP/IP,
then click OK. You may need your Win95/98 CD to complete the
installation. After TCP/IP installation is complete, go back to the
Network window described in Step 4.
Step 6. Select TCP/IP in the list of Network Components.
Step 7. Click Properties, and check the settings in each of the TCP/IP
Properties window: Bindings Tab: both Client for Microsoft
Networks and File and printer sharing for Microsoft Networks
should be selected. Gateway Tab: All fields should be blank. DNS
Configuration Tab: Disable DNS should be selected. IP Address
Tab: Obtain IP address automatically should be selected.
Step 8. With the 802.11A/G ACCESS POINT powered on, reboot the
PC/wireless client. After the PC/wireless client is re-booted, you
should be ready to configure the 802.11A/G ACCESS POINT. See
Chapter 3.
The procedure required to set a static IP address is not too much different from
the procedure required to set to “obtain IP addresses dynamically” - except
that at the end of step 7, instead of selecting “obtain IP addresses dynamically,
you should specify the IP address explicitly.
