39 Chapter 4 PC and Server Configuration This Chapter details the PC Configuration required for each PC on the local LAN. Overview All Wireless Stations need to have settings which match the Wireless Access Point. These settings depend on the mode in which the Access Point is being used. • If using WEP or WPA-PSK, it is only necessary to ensure that each Wireless station's settings match those of the Wireless Access Point, as described below. • For 802.1x mode, configuration is much more complex. The Radius Server must be configured correctly, and setup of each Wireless station is also more complex. Using WEP For each of the following items, each Wireless Station must have the same settings as the Wireless Access Point. SSID (ESSID) This must match the value used on the Wireless Access Point. Note! The SSID is case sensitive. Wireless Security • Each Wireless station must be set to use WEP data encryption. • The Key size (64 bit, 128 bit or 152 bit) must be set to match the Access Point. • The keys values on the PC must match the key values on the Access Point. Note: On some systems, the "64 bit" key is shown as "40 bit" and "128 bit" is shown as "104 bit". This difference arises because the key input by the user is 24 bits less than the key size used for encryption. 4
Wireless Access Point User Guide 40 Using WPA-PSK/WPA2-PSK For each of the following items, each Wireless Station must have the same settings as the Wireless Access Point. Mode On each PC, the mode must be set to Infrastructure. SSID (ESSID) This must match the value used on the Wireless Access Point. The default value is wireless Note! The SSID is case sensitive. Wireless Security On each client, Wireless security must be set to WPA-PSK. • The Pre-shared Key entered on the Access Point must also be entered on each Wireless client. • The Encryption method (e.g. TKIP, AES) must be set to match the Access Point.
PC and Server Configuration 41 Using WPA-Enterprise This is the most secure and most complex system. WPA-Enterprise provides greater security and centralized management, but it is more complex to configure. Wireless Station Configuration For each of the following items, each Wireless Station must have the same settings as the Wireless Access Point. SSID (ESSID) This must match the value used on the Wireless Access Point. Note! The SSID is case sensitive. 802.1x Authentication Each client must obtain a Certificate which is used for authentication for the Radius Server. 802.1x Encryption Typically, EAP-TLS is used. This is a dynamic key system, so keys do NOT have to be entered on each Wireless station. Radius Server Configuration If using WPA-Enterprise mode, the Radius Server on your network must be configured as follow: • It must provide and accept Certificates for user authentication. • There must be a Client Login for the Wireless Access Point itself. • The Wireless Access Point will use its Default Name as its Client Login name. • The Shared Key, set on the Security Profile Settings Screen of the Access Point, must match the Shared Secret value on the Radius Server. • Encryption settings must be correct.
Wireless Access Point User Guide 42 802.1x Server Setup (Windows 2000 Server) This section describes using Microsoft Internet Authentication Server as the Radius Server, since it is the most common Radius Server available that supports the EAP-TLS authentication method. The following services on the Windows 2000 Domain Controller (PDC) are also required: • dhcpd • dns • rras • webserver (IIS) • Radius Server (Internet Authentication Service) • Certificate Authority Windows 2000 Domain Controller Setup 1.
