Web-based Configuration
The 54Mbps 802.11g Wireless Access Point allows configuration through a
Web-based Configuration Utility. The following instructions will complete the
installation of the Wireless Access Point.
Accessing the Web-based Configuration Utility
1. Connect a computer to the Access Point either through wireless or wired
connection. Set a fixed IP address, within the range of 192.168.1.X to the
computer, where X cannot be 254. When attempting to use a wireless
connection, configure the computer advanced options as:
SSID: default
WEP: disable
2. Activate the web browser and enter in the IP address of the AP in the Address
or location field and press Enter. The default value of the Access Point is
192.168.1.254.
3. Follow the on-screen instructions to enter the system password then press
Enter. The default password is “private”.

4
System Configuration
The Web-based Configuration Utility provides 3 items to monitor and configure
the Wireless Access Point: Configuration, Install Wizard and Status. These
core options are essential to enable the Access Point to work properly.

5
3.1 Local Area Network (LAN) Settings:
Three options are provided for the Local Area Network setup:
• Local Area Network
• External DHCP
• Internal DHCP
If an external DHCP server will be used, select Dynamic for the Primary Address
Selection. Otherwise, set the Primary Address Selection to Static IP.
The third choice, internal DHCP server, is available under the Static IP option.
Enter the setting on the DHCP server page and enable the default DHCP server.
Once DHCP is enabled, set the IP address for Static IP in the range of the DHCP
server where the default DHCP server is usually enabled. Click the Apply
button to save the new configuration.

6
3.2 Wireless Settings
The wireless settings will impact the coverage and the performance of the
Wireless Access Point. The Access Point can be operated in three different
bandwidth scenarios:
• G-only (High rate 54Mbps)
• B-only (Low rate 11Mbps )
• Mixed (both below 54M and 11Mbps).
To change the bandwidth setting, click on the change policy… link and select
the appropriate radio policy. Click the OK button to save the new configuration.
Note: Changing the radio policy could result in a loss of connection when using a
wireless connection to the Web-based Configuration Utility.

7
To deliver the throughput enhancement in both mixed and g-only networks, Prism
NitroTM mode can be enabled by using Intersil’s packet bursting technology. The
burst size is adjustable and typically the bigger burst packet, the more 11g
transmission sharing will occur while a mixed network is in effect.
Deselect the Broadcast SSID option to logically hide the Access Point. The
Access Point will refuse any connection request from an unrecognized Network
ID.

8
3.3 Wireless Distribution System (WDS) Links
Use the Wireless Distribution System (WDS) option to extend the range of the
network without having to use cables to link the Access Points wirelessly. Under
WDS, the Access Points are still functioning as regular Access Points, which can
provide the link services to wireless clients.
Enter the MAC address of the Access Point to connect to wirelessly in the
appropriate field by selecting the peer address that the Access Point has located
or by clicking the Add WDS Link button to add a new address. Click the Apply
button to save the new configuration.

9
3.4 Wireless Security
To protect wireless intellectual property, it is important to secure the wireless
connection. This Access Point is equipped a sophisticated security algorithm to
protect against intruders entering your system or listening to conversations over
the network.
3.4.1 ACL
Different access rules may be assigned for each user by adding the MAC
address and the access rights.
Select Enable Access Control List to enable ACL. Enter Specific Clients by
clicking the Add button and entering the MAC address. Highlight each MAC
address and click the appropriate setting to either accept or reject the
connection. Click the Apply button to save the new configuration.

10
3.4.2 WEP
The basic security setting is to enable WEP algorithm by assigning 64 or 128
bits encryption key.
64 bits: ABCDEA01234567899876543210 26 digits
128 bits: ABCDA012345 10 digits
Select Use WEP Security to enable Wired Equivalent Privacy (WEP).
Select a specific length of hexadecimal key and enter the encryption key in
the appropriate field. Click the Apply button to save the new configuration.

11
3.4.3 RADIUS
RADIUS performs the authentication function required to check the
credentials of users and intermediate Access Points and indicates whether
the users are authorized to connect to the network through the Access Points.
Enabling RADIUS is the first step toward building up an 802.1x-capable
environment. It is also a requirement to accommodate the recently introduced
Wi-Fi protected access (WPA-EAP) to wireless networks.
Enter the IP address of RADIUS and the specific UDP Port number, UDP
1812, as well as a Secret key, which is identical to the given key in RADIUS.
Click the OK button to save the new configuration.

12
3.4.4 802.1x Security
IEEE 802.1x will perform a standardized network access control to keep out
unauthorized users, verify the credentials of users with RADIUS and distribute
the encryption key.
It is required to provide RADIUS information in prior to setup 802.1x. Two
lengths of encryption key are provided, 64 or 128 bits.
Select Use 802.1x Security and choose the appropriate Key Size. Set the
Group Key Rekey Settings to No rekeying or enter the frequency to rekey for the
number of minutes or the volume of packets (x 1000). Click the Apply button
to save the new configuration.

13
3.4.5 WPA
The Wi-Fi Protected Access (WPA) is currently the highest level of security a
wireless network can achieve. It is a subset of the security specification and
has been introduced as an interim solution for most known security
weaknesses in comparison to the plain WEP.
TKIP, the successor to WEP, enhances the ability to eliminate the known
vulnerabilities of WEP. Enterprises that already have RADIUS in place can
use WPA with 802.1x or RADIUS (WPA-EAP).
A WLAN client with WPA capabilities is needed to acquire a digital certificate
to be successfully authenticated by RADIUS via a specific EAP channel, TLS.
It is typically called supplicant, or it is associated with a software application.
Software vendors, including Microsoft, offer upgrades for their cards. The
most popular software application that runs on WLAN clients in the market is
the Windows XP SP2. (SP1 with WPA hotfix) provided by Microsoft.
Select Use WPA with RADIUS Server and set the Group Key Rekey Settings
to No rekeying or enter the frequency to rekey for the number of minutes or
the volume of packets (x 1000). Small business and home wireless LANs
can use WPA without 802.1x by selecting Use WPA with pre-shared key
and entering a password phrase. Click the Apply button to save the new
configuration.

14
3.5 Install Wizard
The install wizard provides guided prompts through the main settings for the
Access Point.
Begin by selecting the country in which the product will be used. This is the
organization that certifies the Access Point for use in each country. Choose the
country cautiously in order to comply with the regulation.
Then select a specific SSID as your network identification. Client stations can
roam freely using this product and other Access Point that have the same SSID.
Next, select a number for the radio channel, which determines the channel to be
used to transmit and receive signals.
Finally, set up your security policy by enabling the legacy WEP, WPA, or use the
default setting that will allow any client to associate with the Access Point.

15
3.6 Status
The status screen shows current information on the 54Mbps Wireless LAN
Access Point as Interface Statistics, Wireless Statistics (including Association and
WDS statistics), Client Statistics (including DHCP, Wireless, Access Point and
WDS Links), and Event Reporting.
