This document describes how to configure the wireless client in order to minimize delays when roaming from
access point to access point.

There are no specific requirements for this document.

The information in this document is based on these software and hardware versions:

Cisco 802.11 a/b/g client adapter that runs firmware 4.4 or later

• 

Cisco Aironet Desktop Utility (ADU) version 4.4 or later

• 

The information in this document was created from the devices in a specific lab environment. All of the
devices used in this document started with a cleared (default) configuration. If your network is live, make sure
that you understand the potential impact of any command.

Refer to Cisco Technical Tips Conventions for more information on document conventions.

Complete these steps in order to minimize delays when roaming from access point to access point when you
use the CB21AG/PI21AG (802.11a/b/g wireless client adapter).

Note: These steps optimize roaming delays at the driver layer and are applicable to all authentication types. If
802.1x authentication is used, there might be additional optimizations possible, which are outside the scope of
this document.

Note: Optimizing for faster roaming can potentially contribute to increased battery use and to reduced
throughput.
