System Requirements

In addition to the items shipped with the client adapter, you also need the following items in order to install and use the adapter:

•One of the following computing devices running Windows 2000 or XP:

–Laptop or notebook computer equipped with a 32-bit Cardbus slot

–Desktop personal computer equipped with an empty PCI expansion slot

Note Cisco recommends a 300-MHz (or greater) processor.

•Service Pack 2 for Windows XP

•20 MB of free hard disk space (minimum)

•128 MB of RAM or greater (recommended)

•The appropriate tools for removing your computer’s cover and expansion slot dust cover and for mounting the antenna base (for PCI cards)

•If your wireless network uses EAP-TLS or PEAP authentication, Certificate Authority (CA) and user certificates for EAP-TLS authentication or CA certificate for PEAP authentication

•If your wireless network uses PEAP (EAP-GTC) authentication with a One-Time Password (OTP) user database:

–A hardware token device from OTP vendors or the Secure Computing SofToken program (version 2.1 or later)

–Your hardware or software token password

•The following information from your system administrator:

–The logical name for your workstation (also referred to as client name)

–The protocols necessary to bind to the client adapter, such as TCP/IP

–The case-sensitive service set identifier (SSID) for your RF network

–If your network setup does not include a DHCP server, the IP address, subnet mask, and default gateway address of your computer

–The wired equivalent privacy (WEP) keys of the access points with which your client adapter will communicate, if your wireless network uses static WEP for security

–The username and password for your network account

–Protected access credentials (PAC) file if your wireless network uses EAP-FAST authentication with manual PAC provisioning
