Cisco Systems aironet cb21ag User Manual

You can install both the driver for the CB21AG and PI21AG and the software that runs the adapter by 
running a single executable file that is available from Cisco.com. You must execute this file on devices 
that are running Windows Vista. This driver and softward can be used only with CB21AG and PI21AG 
client adapters.

Client adapters can be used in a variety of network configurations. In some configurations, access points 
provide connections to your network or act as repeaters to increase wireless communication range. The 
maximum communication range is based on how you configure your wireless network.

This section describes and illustrates the two most common network configurations:

Ad hoc wireless local area network (LAN)

Wireless infrastructure with workstations accessing a wired LAN

For examples of more complex network configurations involving client adapters and access points, refer 
to the documentation for your access point.

An ad hoc (or peer-to-peer) wireless LAN (see 

) is the simplest wireless LAN configuration. 

In a wireless LAN using an ad hoc network configuration, all devices equipped with a client adapter can 
be linked together and communicate directly with each other. The use of an infrastructure device, such 
as an access point, is not required.
