Introduction
The Atheros AR5BMB82 MPCI module implements an IEEE 802.11a/b/g/n wireless LAN
(WLAN) AP with DFS Master function. MIMO operation is implemented using three
transmit and three receive chains per the 802.11n standard.
This module may be installed in PC and host processor systems using approved external
antennas. The module may be configured for 2.4 GHz or 5 GHz operation using the Web
Server function. Refer to Appendix A.

AP Network Attachment
and Configuration
This section provides procedures for connecting and configuring the AP. Configuration can
be performed either from a web browser accessing the built-in web server, or by entering
commands using the command line interface (CLI). For detailed information on using the
web server, refer to “AP Web Server” in Appendix A. For detailed information on using CLI,
refer to “AP Command-Line Interface” in Appendix B. For “Factory Default Settings” refer
to Appendix B.

AP Initial Configuration
Configure the AP for its Service Set Identifier (SSID) unique to the application. This
configuration can be done either through a web browser with access to the built-in AP web
server, or by issuing commands through the command line interface (CLI).
Web Browser
Follow these steps to configure the channel frequency and SSID using a web browser:
1. Launch a web browser (Netscape Navigator or Internet Explorer are examples of
commonly used web browsers).
2. From the HPC, enter the IP address that is assigned to the AP as the URL address, for
example http://192.168.1.1.
The Access Point Web Server homepage will appear.
3. Select the Access Point Web Server hotlink.

6. Select the Configuration hotlink from the navigation menu.
The System Configuration window appears.
7.
Enter the SSID (name or address) for the AP in the SSID field. The SSID must be 1–32
characters in length.
To configure a single SSID to have more than one AP in a single SSID, specify a unique
System Name for each AP within that single SSID. Note that range of available channels
will be automatically determined by factory settings.
Note that the radio channel is specified using the IEEE 802.11a standard. For example,
channel 48 is the equivalent of 5.240 GHz. The channel number is derived as:
Channel Number =
Channel Frequency (in MHz) – 5000 MHz
5 MHz
8. Click Update to commit the changes.
Change other settings at this time. Refer to Appendix A for more information.
9. After all configuration changes are complete, reboot the AP to enable them. To reboot the
AP, click on the REBOOT AP button that appears.

A
AP Web Server
Configure the access point (AP) either through a web browser interface to the AP web server,
or using the command-line interface (CLI) through telnet. The web server resides in the AP
and is accessible from any station (STA) that is connected to the AP Infrastructure network.
This appendix describes configuring the AP through the AP Web Server.
Accessing the AP Web Server
Follow these steps to access the AP Web Server:
1. Launch a web browser (Netscape Navigator or Internet Explorer are examples of
commonly used web browsers).
2. From the HPC, enter the IP address that is assigned to the AP as the URL address. For
example, enter http://192.168.1.1. The Access Point Web Server homepage appears.

Configuration Windows
The Web Server Configuration windows allow viewing and editing of configuration
information for the AP. The Web Server provides configuration windows for:
■ System configuration parameters
■ 5 GHz and 2.4 GHz radio configuration parameters
■ 5 GHz/2.4 GHz statistics
■ Security
■ Configuration scripts
■ Firmware updates
To access any of these AP configuration screens, click on the desired hotlink from the
navigation bar on any configuration screen:

Working with Configuration Windows
The Web Server Configuration windows provide a user-friendly interface to aid in quick
configuration of the AP. After making any additions or changes to any configuration
window, update the configuration file to save the changes. The new configuration is not in
effect until the AP is rebooted.
Follow these steps to update configuration files:
1. Enter the configuration updates or changes in the appropriate configuration fields.
2. Click
Update.
3. Click Reboot AP to make the changes
effective.
The web server loses connectivity with the Web Server as the AP reboots.
To reestablish the connection with the Web Server, wait until the AP has completed
rebooting and navigate to the Web Server to resume communication.

FCC Requirements for Operation in the Unites
States
Radio Frequency Interference Warnings & Instructions
This device is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz frequency
range. The FCC requires this product to be used only indoors to reduce the potential for
harmful interference to co-channel Mobile Satellite systems.
High power radars may use the 5.25 to 5.35 GHz or 5.47 to 5.725 GHz frequency ranges in
your area. Such radar stations can cause interference or damage to this device. This device
implements a radar detection function which may cause interruption of normal operation
when a radar signal is detected.
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following methods:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and the receiver
• Connect the equipment into an electrical outlet on a circuit different from that
which the radio receiver is connected
• Consult the dealer or an experienced radio/TV technician for help.
Modifications made to the product, unless expressly approved by Atheros Communication,
could void the user ’s right to operate the equipment.
RF Exposure
CAUTION: To ensure compliance with FCC RF exposure requirements, the
antennas used for this device must be installed to provide a separation
distance of at least 20 cm from all persons. This device must not be located
or operated in conjunction with any other antenna or radio transmitter.
