Introduction
The Atheros Access Point implements an IEEE 802.11b/g wireless LAN
(WLAN) AP or data-oriented Residential Gateway (RG) supporting up to 256
station associations. Rates of 6 to 54 Mbps are supported in standard IEEE
802.11g mode, up to 11 Mbps in 802.11b mode, and up to 108 Mbps in Atheros
Turbo Mode™.
System Requirements
The AP contains a small boot executive that allows the main operating system
software to be downloaded using the Ethernet port over an FTP connection.
The Operating system software can also reside in the Flash memory of the AP,
which allows booting without the need to download the operating system
from the host PC over an FTP connection. A configuration file is created in
Flash memory to store user-configurable parameters such as WEP keys. A
terminal or PC with an Ethernet connection is required to perform the initial
AP configuration. An FTP server is required for firmware update to the AP.
Use the AP Web Server for firmware updates. Refer to Appendix A,
“Firmware Update Configuration Window” for information on the web
server.

AP Network Attachment and
Configuration
This section provides procedures for connecting and configuring the AP to a
Host PC (HPC). Configuration can be performed either from a web browser
accessing the built-in web server, or by entering command 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 Network Connections
Connect the HPC to the AP using one of the following two methods:
■Use an Ethernet crossover cable (not supplied) to connect directly to the
Ethernet port of the HPC. For more information on Ethernet cables, see
Table 2-1.
■Use standard Ethernet cables (not supplied) to connect through a hub or
Ethernet switch.
See Figure 2-1 for an example of the AP to the HPC connections.
Follow these steps to establish the network connections:
1. Connect the AP Ethernet port to the HPC Ethernet card through the
Ethernet hub/switch or an Ethernet crossover cable.

2. Connect the optional RS-232 port to the HPC serial port through a serial
cable. Refer to Appendix C for more information on the serial interface.
3. Plug in the provided power supply to the AP power supply connector.
Network Configuration
Follow these steps to configure the HPC for AP network control:
1. From the HPC’s Start menu, choose Settings and open the Network and
Dial-up Connections dialog box.
2. Right-click on the Local Area Connection icon that belongs to the Ethernet
controller connected to the AP, and select Properties.

AP Hardware Configuration
The Atheros AP hardware allows the configuration of one WLAN. Figure 2-2
shows the physical location of WLAN, panel connectors on the AP hardware,
and the location of the antenna cable and external dipole antenna. An
additional integrated antenna may be provided. Table 2-1 summarizes the
type of cable to use when using the Ethernet wired ports on the AP. You may
use either, or both Ethernet ports.

AP Initial Configuration
This section describes how to configure the AP after booting from Flash
memory. Refer to “Firmware Update Configuration Window” on page A-21
to load the Operating image file to the Flash file system, if the operating
system software should be updated.
Configure the AP for its channel frequency and 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).
The AP can be configured at any time to tailor it for the application
environment. For more information on configuring the AP using the web
browser, refer to “AP Web Server” in Appendix A. For more information on
using the CLI, refer to “AP Command-Line Interface” in Appendix B.
The following description illustrates the use of the web browser. For
information on using the CLI, refer to “Command-Line Interface” on
page 2-9.
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.
