1 PRELIMINARY 1 Introduction Y P O C The Atheros AR5001 Wireless Network Adapter is an IEEE 802.11a two-chip solution reference design based on the Atheros AR5111 and AR5311 chipset. This reference design implements a half-duplex, Orthogonal Frequency Division Multiplexing (OFDM) baseband processor supporting all IEEE 802.11a data rates (6 to 54 Mbps). It also supports the Atheros Turbo ModeTM supporting data rates up to 108 Mbps. The host interface is compatible with the PC Card 7.1 standard.

PRELIMINARY Chapter 2 Device Configuration Configuration of the Atheros AR5001 Wireless Network Adapter can be done through the Network Control Panel (NCP) in adapter properties. You can set the Wireless Network Adapter to work in one of two modes, either infrastructure mode (which leverages an AP) or ad hoc mode (which consists of a group of stations participating in the WLAN).
2 Chapter PRELIMINARY In ad hoc mode, a Wireless Network Adapter works within an independent basic service set (IBSS), as illustrated in Figure 2-2. All stations communicate directly with other stations without an AP. STA1 STA3 Y P O C STA5 STA2 STA4 Figure 2-2. Ad Hoc Mode O D 2-18 • 2-18 • T O N AR5001 STA User’s Guide July 2002 Atheros Communications, Inc.
PRELIMINARY Chapter 2 To configure the AR5001 Wireless Network Adapter: 1. In the Device Manager, right-click “Atheros AR5001 Wireless Network Adapter,” and click Properties to access the properties of the adapter. T O N Y P O C 2. Configuration additions, modifications, and deletions are made under the “Settings” tab of the “Atheros AR5001 Wireless Network Adapter” properties. O D Atheros Communications, Inc.
2 Chapter PRELIMINARY 3. Select one of the configurations under the configuration list, and click Modify to show the “Network Configuration Settings” screen. This property sheet has two pages: General and Security. Table 2-1 provides descriptions for the fields on the General page. Table 2-1. General Dialog Field Descriptions Field Name Description Configuration Name This field identifies the configuration. This name must be unique. Configuration names are case insensitive.
PRELIMINARY Chapter 2 4. To enter a value in the address field, the check box needs to be selected. Typically, an LAA is not required, because the driver automatically loads a unique, globally administered address from the EEPROM. T O N Y P O C 5. Use the Security tab on the Network Configuration Settings dialog to select security features. O D Atheros Communications, Inc.
2 Chapter PRELIMINARY Table 2-2 provides descriptions for the fields on the Security dialog. Table 2-2. Security Dialog Field Descriptions Field Name Description Enable Security Completely enables or disables the IEEE 802.11 wired equivalent privacy (WEP) security feature. Default Encryption Key Defines the type of encryption key to use (either Unique Key or Shared Keys).
PRELIMINARY Chapter 2 Selecting Encryption Types Atheros supports two encryption types; Wired Equivalent Privacy (WEP) and Advanced Encryption Security (AES). While WEP is universally supported and commonly used, AES provides a much higher level of security, that is, frames encrypted with AES are more difficult to decipher without knowing the key. To use AES, you must specify a unique key (refer to Table 2-2 on page 2-22).
2 Chapter PRELIMINARY Table 2-3 provides descriptions for the fields on the Network Configuration Setting, Advanced tab dialog. Table 2-3. Advanced Dialog Field Descriptions Field Name Description Wireless Mode Specifies 802.11a operation. Ad Hoc Mode Specifies a band to establish an ad hoc network if no matching SSID is found after scanning all available modes. 802.11a Turbo Enables or disables Atheros turbo mode for 802.11a radio space. Once enabled, both 802.11a and 802.
PRELIMINARY Chapter 2 NOTE: Fragmentation is currently not supported using AES. O D Atheros Communications, Inc.
2 Chapter PRELIMINARY Infrastructure Mode To configure an Atheros AR5001 Wireless Network Adapter in infrastructure mode: 1. Ensure that the “Locally Administered Address” checkbox is unchecked. T O N Y P O C 2. Enter information in the General dialog as summarized in Table 2-4. O D Table 2-4. Infrastructure Mode General Dialog Field Descriptions Field Name Description Configuration Name This field identifies the configuration. This name must be unique. Configuration names are case insensitive.
PRELIMINARY Chapter 2 Usually infrastructure mode is used in an enterprise environment where APs are installed and maintained by corporate IT staff. Much of the data in the enterprise network is confidential. It is important to configure security to make sure only stations with appropriate keys can receive sensitive data. The Atheros AR5001 Wireless Network Adapter and NDIS driver support key lengths of 40 bits, 104 bits, and 128 bits.
2 Chapter PRELIMINARY Ad Hoc Mode An ad hoc network usually is a short-lived network with a small number of stations. The network is usually created for a special purpose such as exchanging data between friends, or between customer and client. Because the duration of the ad hoc network tends to be limited, Power Saving and Security features are not typically a requirement. For ad hoc network activity, the Power Saving and Security features can be disabled.
PRELIMINARY Chapter 2 Table 2-5 summarizes the field description for the General dialog in ad hoc mode. Table 2-5. Ad Hoc Mode General Dialog Field Descriptions Field Name Description Configuration Name This field identifies the configuration. This name must be unique. Configuration names are case insensitive. Network Name (SSID) A network name is mandatory for ad hoc mode. The SSID for all stations in a single ad hoc network must be the same. Network Connection Ad Hoc.
2 Chapter PRELIMINARY 3. Select “Internet Protocol (TCP/IP)” and click Properties. O D 2-30 • 2-30 • T O N AR5001 STA User’s Guide July 2002 Y P O C Atheros Communications, Inc.
PRELIMINARY Chapter 2 4. Click “Use the following IP address” and input an IP address and Subnet mask. Assigning an IP address and Subnet mask allows stations to operate in infrastructure mode and to have Internet access. “Default gateway” and “DNS server” information is also required. IP configuration information (DHCP or assigned IP address, Gateway and DNS server IP addresses) is usually obtained from the corporate IT staff. 5.
2 Chapter PRELIMINARY 6. Choose Start > Programs > Accessories > Command Prompt to open the DOS command prompt window. 7. Type “ipconfig” at the C:\> prompt to determine if the TCP/IP configuration has taken effect. To test IP connectivity in ad hoc or infrastructure mode, use the ping command. When a TCP/IP connection is established, the LinkMon utility (refer to “LinkMon” on page 7-1) can be used to monitor the Atheros AR5001 Wireless Network Adapter operating status.
PRELIMINARY Chapter 2 8. To map the drive on another machine to your computer, right-click “My Computer” and click Map Network Drive... T O N Y P O C 9. After mapping the drive, you can perform file transfers, use video streaming applications, and all other network data transfers that are normally performed with wired 10/100 Ethernet connections.
