A P P E N D I X E Configuring the Client Adapter through Windows XP This appendix explains how to configure and use the client adapter with Windows XP.
Appendix E Configuring the Client Adapter through Windows XP Overview B E TA D R A F T - C I S C O C O N F I D E N T I A L Overview This chapter provides instructions for minimally configuring the client adapter through Windows XP (instead of through ACU) as well as for enabling one of the three security options that are available for use with this operating system.
Appendix E Configuring the Client Adapter through Windows XP Overview B E TA D R A F T - C I S C O C O N F I D E N T I A L Two 802.1X authentication types are available when configuring your client adapter through Windows XP: • EAP-TLS – This authentication type is enabled through the operating system and uses a dynamic, session-based WEP key, which is derived from the client adapter and RADIUS server, to encrypt data. RADIUS servers that support EAP-TLS include Cisco Secure ACS version 3.
Appendix E Configuring the Client Adapter through Windows XP Configuring the Client Adapter B E TA D R A F T - C I S C O C O N F I D E N T I A L Configuring the Client Adapter Follow the steps below to configure your client adapter using Windows XP. Note If you installed ACU but intend to use Windows XP to configure the client adapter, open ACU and make sure the Allow Windows To Configure My Wireless Network Settings option is selected on the Profile Manager screen.
Appendix E Configuring the Client Adapter through Windows XP Configuring the Client Adapter B E TA D R A F T - C I S C O C O N F I D E N T I A L Step 6 Make sure that the Use Windows to configure my wireless network settings checkbox is selected. Step 7 Select the SSID of the access point to which you want the client adapter to associate from the list of available networks and click Configure.
Appendix E Configuring the Client Adapter through Windows XP Configuring the Client Adapter B E TA D R A F T - C I S C O C O N F I D E N T I A L Step 10 Select the Network Authentication (Shared mode) checkbox if you want to use shared key, rather than open, authentication with the access point. Open authentication allows your client adapter, regardless of its WEP settings, to authenticate and attempt to communicate with an access point.

A P P E N D I X F Performing a Site Survey This appendix explains how ACU’s site survey tool can be used when conducting a site survey.
Appendix F Performing a Site Survey Overview B E TA D R A F T - C I S C O C O N F I D E N T I A L Overview Note This appendix applies only to people who are responsible for conducting a site survey to determine the best placement of infrastructure devices within a wireless network. ACU’s site survey tool can assist you in conducting a site survey. The tool operates at the RF level and is used to determine the best placement and coverage (overlap) for your network’s infrastructure devices.

B E TA D R A F T - C I S C O C O N F I D E N T I A L G L O S S A R Y 802.1X Also called 802.1X for 802.11. 802.1X is the new standard for wireless LAN security, as defined by the Institute of Electrical and Electronics Engineers (IEEE). An access point that supports 802.
Glossary B E TA D R A F T - C I S C O C O N F I D E N T I A L C CCK Complementary code keying. A modulation technique used by IEEE 802.11b-compliant wireless LANs for transmission at 5.5 and 11 Mbps. Client A radio device that uses the services of an access point to communicate wirelessly with other devices on a local area network. CSMA Carrier sense multiple access. A wireless LAN media access method specified by the IEEE 802.11 specification.
Glossary B E TA D R A F T - C I S C O C O N F I D E N T I A L F File Server A repository for files so that a local area network can share files, mail, and programs. Firmware Software that is programmed on a memory chip and kept in a computer’s semi-permanent memory. Fragmentation Threshold The size at which packets will be fragmented and transmitted a piece at a time instead of all at once. The setting must be within the range of 64 to 2312 bytes.
Glossary B E TA D R A F T - C I S C O C O N F I D E N T I A L L LEAP, or EAP-Cisco Wireless, is the 802.1X authentication type that is available for use with operating systems that do not have built-in EAP support. Support for LEAP is provided in the client adapter’s firmware and the Cisco software that supports it, rather than in the operating system. With LEAP, a username and password are used by the client adapter to perform mutual authentication with the RADIUS server through an access point.
