This document provides information on the most frequently asked questions (FAQ) asked about Cisco Aironet Client Adapters used with Microsoft Windows operating systems. Refer to Cisco Technical Tips Conventions for more information on document conventions. Q. Where can I find the latest utilities, drivers, and firmware for my Windows client? A. Cisco Aironet equipment operates best when all components are loaded with the most current version of the software. You can download the latest software and drivers at Wireless Downloads ( registered customers only) . A. The 802.11b and 802.11g standards define a total of 14 frequency channels in the 2.4 GHz band. The 802.11a standard defines 12 channels in the 5 GHz band for UNII-1 communications. In 802.11b/g installations, channels 1 through 11 can be used within the United States. These are public frequencies and are unlicensed by the Federal Communications Commission (FCC). Most of Europe can use channels 1 through 13. Channels 1 through 14 are allowed in Japan. In 802.11a access point/client installations, channels 36, 40, 44, 48, 52, 56, 60 and 64 can be used in the United States. These are public UNII-1 frequencies and are unlicensed by the FCC. Most of Europe can use these same channels. Channels 34, 38, 42 and 46 are allowed in Japan. A. The typical range for a client card depends on many factors. Among them are data rate (bandwidth) desired, antenna type and cable length (where applicable), and the device that sends and receives the transmission. In an optimal installation, the range can be up to 300 feet. Due to the reduced maximum allowable transmit power on the 802.11a band, the range for 802.11a installations is less. The best estimates of performance and range for a given install site come from a presales site survey. Contact your Cisco Systems Engineer (SE), Cisco account team or Cisco authorized wireless reseller for assistance in the coordination of a site survey by a qualified survey partner. A. Yes. The major difference between the two product lines is the power of the radio. The 350 Series has the stronger radio at 100 milliwatts. In a mixed installation, the shorter range of the 340 Series prevails. Both series operate only in the 802.11b frequency band. The CB20A Card operates in the 802.11a band, and the CB21AG or PI21AG Cards can operate in any of the three bands (802.11a, b or g), but only in one band at a time. A. The WZC service is built into the Windows XP operating system. The Microsoft WZC service is designed to dynamically select the wireless network to which it will attempt a connection, based either on your preferences or on default settings. This includes the automatic selection and connection to a more preferable wireless network when it becomes available. The WZC service is not installed by default during a Windows XP installation. Complete these steps in order to install the WZC service on your system: Click Start, then click Control Panel. Click Performance and Maintenance, click Administrative Tools, and then click Services. Double-click the Wireless Zero Configuration service. On the General tab, click Stop. In the Startup type list, click Disabled, then click OK. The WZC is now disabled and does not reload when you restart your computer. A. When you install the client driver and utilities for a Cisco Aironet 340, 350, and CB20A Wireless LAN Client Adapters, a utility called Aironet Client Monitor (ACM) also is installed. ACM is an optional application that provides a small subset of the features available through ACU. Specifically, ACM enables you to access status information about your client adapter and perform basic tasks. ACM is accessible from an icon in the Windows system tray, which makes ACM easily accessible and convenient to use. Refer to Using the Aironet Client Monitor (ACM) for information on ACM and the supported features. For Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG), a utility called Aironet System Tray utility (ASTU) is installed with the other client utilities. ASTU is an optional application that provides a small subset of the features available through ADU. Specifically, ASTU enables you to access status information about your client adapter and perform basic tasks. ASTU is accessible from an icon in the Windows system tray, which makes ASTU easily accessible and convenient to use. The ASTU icon appears only if a client adapter is installed into your computer and you have not disabled ASTU. Refer to Using the Aironet System Tray Utility (ASTU) for more information on ASTU and the features supported Note: Sometimes, you need to select the utilities that you want to install during the client software installation. A. The most common cause of this behavior is the inability of the PC to communicate with the card through the PCMCIA socket. Check the driver for your PC card socket. If the driver is a CardBus driver, check whether it is 32-bit only. The Cisco Aironet card requires 16-bit access. If the driver for the socket only works in 32-bit mode, you must contact the manufacturer of the computer for a 16-bit version. If the manufacturer cannot provide you with one, there are third-party PCMCIA card and socket service manufacturers who sell products that support 16-bit access. The CB20A and CB21AG Cards are CardBus compliant, and only work with hardware sockets and drivers that supply 32-bit access. The PI21AG is a PCI card, so other problems can contribute. A. An access point has the physical capacity to handle 2,048 MAC addresses. However, the access point is a shared medium and acts as a wireless hub. Therefore, a large number of users on an individual access point degrades performance. The best estimates of potential client population for a given install site come from a presales site survey. Contact your Cisco Systems Engineer (SE), Cisco account team or Cisco authorized wireless reseller for assistance in the coordination of a site survey by a qualified survey partner. The radio firmware resides on the client device, and in the case of the PC card, is removed when the card is removed. The client driver is the software that manages interactions between Windows (or another operating system) and the hardware. The ACU is a utility to manage the card and the radio. These three pieces of software have different functions, but work together to provide wireless connectivity to your client. You must always use the most recent versions of the software available. These three pieces of software have been combined into the Cisco Aironet Client Adapter Installation Wizard for Windows available at Wireless Downloads ( registered customers only) . Q. Do autonomous access points (APs) support load balancing with all Wireless client adapters? A. Autonomous APs support load balancing only with Cisco 350 Wireless Cards with Aironet extensions enabled. Because this is not included in the Cisco Compatible Extensions (CCX) program, it does not work with any other wireless cards.
Designed with enterprise-class security requirements in mind, the Cisco Aironet 802.11a/b/g Wireless PCI Adapter uses the 802.1X standard for port-based network.
