POINT

Overview of the 802.11 a+g Access Point

The 802.11A+G ACCE SS POINT is an access-point based on IEEE 802.11a+g based 2.4GHz and 5 GHz radio technology. It contains an 802.11a+g and a full-duplex 10/100 LAN interfaces. The 802.11A+G ACCESS POINT can function as a simple Access Point (AP), and act as the center point of a wireless network supporting a data rate of up to 54 Mbps. It can also connect these wireless devices to wired network through the LAN int erface.

The 802.11A+G ACCESS POINT can also function in a repeater mode, which is used to extend the physical coverage of the wireless network. Finally, the 802.11A+G ACCESS POINT can also function in a Wireless Distribution System (WDS) mode. Multiple

802.11A+G ACCESS POINT’s can be configured to operate in the WDS mode to interconnect wired LAN segments that are attached to these 802.1 1A+G AC CESS P OINT’s .

Since the 802.11g shares the same 2.4GHz radio band as the 802.11b technology, it can interoperate with existing 11Mbps 802.11b devices. Therefore you can protect 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 conc erns in a wireless L AN environment, d ifferent levels of security can be enabled in the 802.1 1A+G ACCE SS PO INT, including:

• To disable SSID broadcast to restrict association to only those client stations that a re alread y pre-configured with the correct SSID

• To enable WEP (Wi reless 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(s).

• 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) works with a RADIUS server to provide stronger authentication as well as data integrit y and pri vacy.

Network Configuration Examples

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 three network configurations

AS AN ACCESS POINT

When configured in the Access Point mode, the 802.1 1A+G AC CESS 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. This is shown in the diagram below .

AS A STAND-ALONE REPEATER

The purpose of a repeater is to expand an existing infr astructure BSS. When conf igured to operate in the Repeater Mode, the 8 02.11A+G A CCESS PO INTs sit between wir eless stations and a “root” AP whose BSS is being expan ded, as shown belo w:

AS A POINT TO MULTI-POINTS BRIDGE

When configured to operate in the Wireless Distribution System (WDS) Mode, the

802.11A+G ACCESS POINT provides bridging functions between the LAN behind it and separate LANs behind other AP’s operating in the WDS mode. The system will support up to eight such AP’s in a WDS configuration.

Note that an 802.11A+G ACCESS POINT running in the WDS mode can also support wireless stations simultaneously, as s hown in the left m ost AP in the dia gram below:

IEEE 802.11a+g Access Point User’s Guide

Setting 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, whi ch can be don e using one o f the followin g two method s.

STATIC IP

The default IP address of t he L AN int erf ac e of a n 802 .11A+G A CCESS P OIN T is a priv at e I P 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 192.1 68.1.2 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 netwrok settings (if there is any) or user’s preference.

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 depending 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.

Chapter

Installing the 802.11A+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.

What’s in the Box?

The 802.11A+G ACCESS POIN T package conta ins the followin g items:

 One 802.11A+G ACCESS POINT  One 5V AC power adapter with a barrel con nector  CD of the 802.11A+G ACCESS POINT User’ Guide

Connecting the Cables

The Back Panel of the 802.11A+G ACCESS POINT appears as follows:

Follow these steps to install your 802.1 1A+G AC CES S 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.

Configuration Steps Required for the 802.11A+G A CCESS POINT

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. This means that the 802.11A+G ACCESS POINT normally will not need to enable the DHCP server function.

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 255.25 5.255.0). Therefore, during the system installation time, you need to build an isolated environment with

the 802.11A+G ACCESS POI NT and a PC, and then perf orm the followin g step s:

 Manually change the IP address of the PC to becom e 192.168.1 .3

 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. 168.23.25 4.

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 s ame IP address as another machi ne.

Please note that after you change the IP address of the ACCESS 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.

 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.

Setting up a Windows PC or wireless client as DHCP clie nts

The following will give detailed steps of how to configure a PC or a wireless client to “obtain IP addresses automatically”. For other types of configuration, please refer to the corresponding user manual.

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/XP, please consult the manufacturer’s documentation.

Step 1.

From the Win95/98/2000 Start Button, select Settings, then Control Panel. The Win95/98/2000/XP 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. Otherwise, select Add to ins tall it now.

Step 4.

Step 5.

Step 6.

Step 7.

In the new Network Component Type window, select Protocol.

In the new Select Network Protocol window, select Microsoft in the Manufacturers ar ea.

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 shown in S tep 4.

Select TCP/IP in the list of Network Components.

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 IP Address Tab: Obtain IP address automatically

should be selected.

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 rebooted, you should be ready to configure the 802.11A+G ACCESS POINT. See Chapter 3.

The procedure required to set a static I P addr ess is not too much dif ferent fr om t he pr ocedur e required to set to “obtain IP addresses dynamica lly” - except that at the end of step 7, instead of selecting “obtain IP addresses dynamically, you should specify the IP address ex plicitly.

Basic Configuration of the 802.11A+G ACCESS POINT

This section describes the basic configuration procedure for the 802.11A+G ACCESS POINT. It describes how to set up the 802.11A+G ACCESS POINT for wireless connections, and the configuration of the local L AN environment.

The 802.11A+G ACCESS POINT is designed so that all basic configuration may be effected through the a standard Web browser such as Microsoft Internet Explorer.

From a PC that has been configured as described in Chapter 2, enter the IP address of the

802.11A+G ACCESS POINT as the URL in your br owser , e.g.

http://192.168.1.1.

Note: The IP address of your PC must be in the same IP subnet as the 802 .11A+ G ACCESS POINT.

The Home Page of the 802.11A+G ACCESS POINT screen will appear, with its main menu displayed on the right hand side of the windo w. The m ain menu includ es the fo llowing cho ices: Setup Wizard, Device Status, Advanced Settings, Syste m Tools, and Help; these can be used to navigate to other menus.

Logging On

If you attempt to access a configuration item from the browser menu, an administrator login screen will appear, prompting you for the p assword in order to log on.

If you are logging on for the first time, you should use the factory default setting “password”. The password is always displaye d as a string of aste risks (“*”). Click the LOG ON button to start the configuration session.

Setup Wizar d

The Setup Wizard will guide you through a series of configuration screens to set up the basic functionality of the device. After you finish these screens, press the “finish” button on the last screen to make all your modifications eff ective.

TIME SETTINGS

After logging in, the time settings page appears. The device time is automatically set to the local time of the management PC at the first time a connection is made. To modify the device’s time, modify the appropriate fields, then cl ick NEXT.

DEVICE IP SETTINGS

The Device IP setting screen allows you to configure the IP addr ess and s ubnet of the devi ce. Although you can rely on a DHCP server to ass ign an IP addres s to the 802.11A+G AC CES S POINT automatically, it is recommended that you configure a static IP address manually in most applications.

If you choose to assign the IP address manually, check the button that says “Assign static IP

to this device” and then fill in the following fields IP Address and IP Subnet Mask: These values default to 192.168.1.1 and 255.255.255.0,

respectively. It is important to note that there are similar address es fallin g in the standard private IP address range and it is an essential security feature of the device. Because of this private IP

address, the device can no l onger be acc essed (seen) f rom the Intern et.

Gateway IP Address: Enter the IP address of your de fault gatewa y DNS Server: The Domain Name System (DNS) is a server on the Internet that translates

logical names such as “www.yahoo.com ” to IP addres ses like 66.21 8.71.8 0. In order to do this, a query is made by the r eques ting de vice to a DN S ser ver to prov ide the n ec ess ary inform ation . If your system administrator requires you to manually enter the DNS Server addresses, you should enter them here.
