1 Introduction
1.1 Overview
This document describes the functions of the Marvell Wireless Client Card
Configuration Utility for the Marvell MC8687P Mini PCI Express 802.11 b/g
WLAN client card.
1.2 Wireless Networks
The Marvell client card operate similar to the Ethernet card, except that a radio
replaces the wires between communication devices. All existing applications that
operate over Ethernet operate a Marvell wireless network without any
modification of need for special wireless networking software. The Marvell
MC8687P client card supports the following network technologies:
• Ad-Hoc (peer-to-peer) mode
• Access Point (AP) Infrastructure mode
1.2.1 Ad Hoc Mode
In Ad-Hoc mode (also refereed to as peer-to-peer mode), wireless clients send and
receive information to other wireless clients without using an AP. In comparison
to Infrastructure mode, this type of WLAN connection only contains wireless
client. Ad-Hoc mode is useful for establishing a network where wireless
infrastructure does not exist or where services are not required. Two or more
computers can establish an Ad-Hoc network when within range of one another.
Ad-Hoc mode is used to connect network computers at home or in small offices.
It can also be used to set up a temporary wireless network for meetings.
1.2.2 Infrastructure Mode
In infrastructure mode, wireless devices communicate with other wireless devices
or devices on the LAN side wired network through APs. When communicating
through wired networks, client card sends and receive information through APs.
Access Points are typically strategically located within an area to provide optimal
coverage for wireless clients. A large WLAN uses multiple APs to provide
coverage over a wide area. APs connect to a LAN through a wired Ethernet
connection. APs send and receive information from the LAN through this wired
connection. Most corporate WLANs operate in Infrastructure mode because they
require access to the wired LAN in order to use services such as file servers or
printers.

2 Marvell Wireless Configuration Utility Overview
2.1 Overview
The Marvell Wireless Client Card Configuration Utility is a Windows® based
application that allows configuration and management of the Marvell high
throughput client card. The Marvell Wireless Configuration Utility sets up
profiles and performs other wireless network management tasks. For information
on installing the Marvell Wireless Configuration Utility see the Installation
Guide.
2.2 Marvell Configuration Utility
Once install, the Marvell Wireless Configuration Utility is accessed from the
Start menu or from the Desktop.
Start menu:
• Start > Marvell Wireless Configuration Utility
• Start > Program > Marvell > Marvell Wireless Configuration Utility
Desktop:
• Double-click the Marvell Wireless Configuration Utility Icon
Figure 1: Marvell Wireless Configuration Utility Icon
2.2.1 Windows XP and Windows Server 2003 Users
For the Windows XP and Windows Server 2003, either the Windows Wireless
Zero Configuration Service of the Marvell Wireless Configuration Utility can be
used to configure the Marvell client card. For further information on the Windows
Wireless Configuration Service, refer to Windows documentation. Proprietary
Note: When using the Marvell Wireless Configuration Utility, Marvell
recommends turning off the Windows Wireless Zero Configuration Service,
which is enabled by default. Both utilities should not be used at the same time.
Disabling Windows Wireless Zero Configuration Service
To disable the Wireless Zero Configuration Service:
1. Start the Marvell Wireless Configuration Utility
2. Click the Admin tab.
3. Select the Stop Windows Wireless Zero Configuration Service check box.

2.3 Security
Implementing a security infrastructure to monitor physical access to WLAN
networks is more difficult than monitoring access on wired networks. Unlike
wired networks where a physical connection is required, anyone within the range
of a wireless AP can send and receive frames, as well as listen for frames being
sent.
IEEE 802.11 and IEEE 802.1X define a set of standards and protocols for use in
minimizing the security risks on wireless networks. These include the
authentication modes used to authenticate the wireless client station and the
wireless AP to be connected, complemented by different encryption methods used
for data to be transmitted over the wireless network. Four of these security
standards are as follows:
• 802.1X-802.1X authentication provides authenticated access to 802.11
wireless networks and to wired Ethernet networks. 802.1X minimizes
wireless network security risks by providing user and computer
identification, centralized authentication, and encryption services based on
the Wired Equivalent Privacy (WEP) algorithm. 802.1X supports the
Extensible Authentication Protocol (EAP). EAP allows the use of different
authentication methods, such as smart cards and certificates.
• Wired Equivalent Privacy (WEP) – WEP is a basic securing
implementation according to the IEEE 802.11 standard. Due to various
security issues WEP encryption is vulnerable and was therefore
superseded by WPA and WPA2 encryption.
• Wi-Fi Protected Access (WPA) – WPA is a security implementation
based on a subset of the 802.11i standard. WPA provides enhanced
security for wireless networks when used with the Temporal Key Integrity
Protocol (TKIP) and the Message Integrity Check (MIC) algorithms.
• Wi-Fi Protected Access 2 (WPA2) – WPA2 is the next generation Wi-Fi
security, based on the final 802.11i standard. WPA2 offers the strongest
available security in the form of Advanced Encryption Standard (AES)
level encryption, plus faster roaming between APs.
Security Configurations
The Marvell Wireless Configuration Utility supports the following security
features:
• Authentication Modes

• Auto Switch – Auto Select Authentication modes (no key or a pre-shared
WEP key is required)
• WPA-PSK – WPA Pre-Shared Key
• WPA2-PSK – WPA2 Pre-Shared Key
If Open System or Auto Switch is selected as Authentication Mode, Security Off
and WEP are available as Encryption Method. If Shared Key is selected as
Authentication Mode, WEP is pre-selected as Encryption Method. For details on
how to configure the WEP key(s), see Section 3.2.3.1
