WPA Migration Mode Now Supported by Clients
Client adapter firmware version 5.40.10 and the software components included in Cisco Aironet client
adapter Install Wizard version 1.3 now support Wi-Fi Protected Access (WPA) migration mode for 350
series and CB20A cards. WPA migration mode is an access point setting that enables both WPA and
non-WPA clients to associate to an access point using the same SSID. To use this feature, the access
point must be configured for migration mode (WPA optional with TKIP+WEP128 or TKIP+WEP40
cipher).

Radio Management Support on CB20A Cards
In Windows ACU version 6.3 the Enable Radio Management Support parameter has been added to the
Advanced (Infrastructure) Parameters screen in ACU for CB20A PC-Cardbus cards. Checking this check
box enables the access point to which the client adapter is associated to control the use of radio
management (RM), provided RM is enabled on the access point. RM, a component of the Cisco
Structured Wireless-Aware Network (SWAN), is a system-wide feature that involves multiple
infrastructure nodes. The RM feature on the access point acts on radio measurement requests from other
network devices to instruct the access point and its associated clients to perform required radio
measurements and then report them.
