1. Introduction
The Access Point is a wireless LAN bridge that can act as the connection point
between the Ethernet CSMA/CD protocol and the wireless CSMA/CA protocol. The
Access Point can be easily integrated into your existing wireless network. In large
installations, the roaming functionality provided by multiple Access Points allows
wireless users to move freely throughout the facility while maintaining seamless,
uninterrupted access to the network.
This document describes the steps required for the initial IP address assign and
AP configuration. The description includes the implementation of the above steps.
1.1 Installation Requirements
Before you begin installation, make sure that you have the following items:
•The Access Point
•The AC to DC power adapter
•The Documentation CD
You will also need:
•A computer that is connected to the same network as the Access Point.
1.2 System Requirements
•Desktop or laptop PC configuration through Ethernet:
•Operating System: MS Windows 9X, ME, 2000, XP.

2. Wireless LAN basics
Wireless LAN network defined by IEEE 802.11b standard committee could be
configured as:
•Ad Hoc wireless LAN, or
•Infrastructure wireless LAN.
Ad Hoc network is a group of notebooks with wireless LAN PC card called a
BSS (Basic Service Set). These notebooks use their wireless LAN PC cards to
communicate with each other, and notebooks cannot connect to the Internet.
Figure 2-1 Ad Hoc wireless network
The most obvious differentiation between Infrastructure wireless network and
Ad Hoc wireless network is that the notebooks in Infrastructure wireless network
can make use of the resource in the Internet through Access Point.

Figure 2-2 Infrastructure wireless network
To set up your notebook’s network as the type of “Ad Hoc” or “Infrastructure”
wireless network depends completely on your requirement. Generally, if your network
environment has an Access Point, we recommend that you set it as “Infrastructure”
to connect to the Internet.

3. Installation
This section describes the procedures for installing the Wireless LAN Access Point
under Windows 98 SE operating system.
Before You Start
Before setting up your Access Point, ask your network system administrator for the
following information:
•Your IP address, gateway address, and subnet mask if you’re not using a
DHCP server.
•The MAC address from the label on the bottom of the Access Point.
•Your Wireless Client Name
•Your Wireless SSID
•Your computer’s unique client name and workgroup name
•For your network account, your user name and password.
Every computer on a network is identified by a unique network address. There are
two methods of assigning network addresses to computer on a TCP/IP network:
•Static IP addressing
•Dynamic IP addressing (DHCP)
In networks with static IP addressing, the network administrator manually assigns
an IP address to each computer. Once a static IP address is assigned, a computer
uses the same IP address every time it reboots and logs on to the network. You may
manually change the IP address in the Network Properties dialog box. Networks
using static IP addresses are easy to set up and do not require additional network
management software.
In networks with dynamic IP addressing, a DHCP server in the network dynamically
assigns IP addresses to all clients every time they log on to the network. Network
using dynamic IP addresses require setting up and running a DHCP Server or
installing the Wingate software package.

3.1 Install the SNMP Manager application
Under Windows 98 SE
Step 1. Insert the given Documentation CD and then double click “MY Computer”
icon on desktop. In my computer window, double click the Pure_AP CD
Drive icon. Choose SNMP folder and then double click Setup to install
“SNMP Manager”. It opens the InstallShield Wizard dialog box as shown
next page then
click Next.

Step 2. Software License Agreement, click Yes to accept.
Step 3. Click Next to install to this folder.

10
Step 4. Setup will add program icons to the Program Folder listed below. You may
type a new folder name, or select one from the Existing Folders list. Click Next
to continue.
Step 5. Review settings before copying files, click Next to start copying files.

11
Step 6. Start copying files.
Step 7. Click Finish to complete Setup.

3.2 Setting the IP Address
Each station or device on your network must have a unique IP address.
Following these steps to setting the IP address:
Step 1. Connect an Ethernet station and the Access Point on the same subnet. The
simplest way to accomplish is to connect the Access Point and the Ethernet
station to the same hub. You need to check if the station IP address and the
Sub-net mask are configured properly. Also the new IP address for the
Access Point must correspond to the Subnet mask.
Step 2. In my computer window, double click the Pure_AP CD Drive icon. Choose
IP_Config folder and then double click IPConfig to execute. Then IPConfig
screen displays as shown.

13
Step 3. Type the "Access Point MAC Address" from the label on the bottom of the
Access Point, type the “Config IP” address from your system administrator,
and then click “OK”.
Step 4. Open a MS-DOS Prompt window and type ping followed by the IP address
used in the IP Config. The IP address is assigned to the Access Point . The
Access Point’s replies to the ping confirm that the IP address was assigned
correctly.
Step 5. If you get a ping reply, then the IP address has been temporarily set. In order
to set it permanently you need to run SNMP Manager without powering off
the Access Point.

3.3 Using the SNMP Manager
On the Start Menu, choose Start->Programs->SNMP Manager.

15
File menu
When the application opens, under the File Menu there are the following
submenus:
Connect to AP
Using this submenu you can directly connect with the Access Point by typing
its IP Address in the panel which appears and at the Community field, type the
appropriate password (The default password is “public”). Additionally you
have to select the User or Administrator Authority in the Authority
combo-box. User Authority allow you only to view and not to set or save
changes to the Access Point Configuration, while Administrator Authority
allow you to either view or set changes to the Access Point Configuration.
Then press OK.
In case of a successful connection to the Access Point, the following window
appears press “OK”

16
If your network has a DHCP server IP Address can be automatically assigned
to the Access Point.

necessity of knowing its IP Address. Choose this submenu in order to find the
Access Points available for connection. Select one of the available Access
Points and press “Connect”, then appears indicating the IP Address of the
selected Access Point and prompting you to select Authority and to write the
appropriate password at the community field. Then press “OK”.
In case of a successful connection to the Access Point, the following window
appears press “OK”

17
When the connection has been successfully established, you get a message in
the left bottom corner indicating, “Get Configuration done” and on the right
bottom corner the “IP Address” of the connected Access Point.
File menu
The “File menu” contains the following enabled submenus.
Close Connection AP
Terminates the connection with the Access Point. You can find and associate
with another access point by selecting the “Find Access Point” after close the
connection.
Download changes

Setup menu
As soon as the connection has been established, you are able to start viewing
or setting the Access Point parameters. Under the “Setup” menu, there are
the following submenus.
Bridge
Under the “Bridge” submenu, there are two options:
—IP configuration
By choosing this option the window of appears.
If DHCP client is not enabled, “IP Address” and ”IP Mask” can be modified

19
through “IP Configuration”. If DHCP client is enabled the IP Address field
displays IP Address that was dynamically assigned to the AP by the network
DHCP server and the IP Mask field displays IP Mask utilized by the network
DHCP server. Additional you have to select the Primary Port which is the
interface that determines the DHCP server. If changes are made, you need to
“Download Changes” under the “File” menu in order to save them.
Bridge IP Configuration Parameters
MAC Address: Unique 48-bit, hard-coded Media Access Control address
known as the station identifier.
IP address: Network-assigned Internet Protocol address of the Access
Point.
IP Mask: Four sets of three digits that divides a network into subnet works.
— Filtering
If the IP Routing is enabled only the IP protocol packets will pass through the
WLAN and any other protocol filtered out.

20
Wireless LAN
Under this submenu there are the following three options available.
— Privacy options
By choosing this option you must define the encryption key values of your
choice. There are four 5 Hex digit encryption keys available if you select 64 bit
WEP or there are four 13 Hex digit encryption keys available if you select 128
bit WEP. The key is enabled only if you select it in the “Default key” option.
Enable the WEP (Wired Equivalent Privacy) option in order to activate WEP
encryption for transmissions between the stations and the Access Point. WEP
is an authentication algorithm, which protects authorized Wireless LAN users
against eavesdropping.
For the 64-bit encryption, each key is required to enter 5 Hex digits. For
example: 11 22 33 44 55 66. The 128-bit encryption requires each key to enter
13 Hex digits. For example: 12 34 56 78 9A BC DE F0 11 22 33 44 55.
Note: The Authentication type must be the same on the wireless station and on the access
point. All shared keys on the wireless station must be the same as those on the
access point with which the client station is associated.
There are four 5 Hex digit encryption keys available if you select 64 bit WEP.
