Cisco Cisco Aironet 350 Wireless LAN Client Adapter

Access points to which your client adapter may attempt to authenticate must use the following 
firmware versions or later: 12.00T (340, 350, and 1200 series access points) or Cisco IOS Release 
12.2(4)JA (1100 series access points).

To use WPA or fast roaming, access points must use Cisco IOS Release 12.2(11)JA or later. 
To use radio management (RM), access points must use Cisco IOS Release 12.2(13)JA or 
later. To use QoS and WMM, access points must use Cisco IOS Release 12.3(2)JA or later.

All necessary infrastructure devices such as access points, servers, gateways, and user databases 
must be properly configured for any authentication type you plan to enable on the client.

Use caution when bundling the client adapter software into a customized installation image. If the 
registry settings are modified, the software may not install and uninstall properly. 

The Install Wizard automatically upgrades the client adapter firmware to the version included in the 
Install Wizard file.

Applications such as AirMagnet and Wild Packets may fail after the firmware is upgraded. To resolve 
this problem, use ACU to downgrade the firmware to the previous version. Older versions of client 
adapter firmware are available from the Software Center on Cisco.com.

When you uninstall ACU, make sure you reboot your computer when prompted. Otherwise, the system 
may be rendered unable to boot, displaying the message “The Logon User Interface DLL cswGina.dll 
failed to load. Contact your system administrator to replace the DLL or restore the original DLL.”

All profiles are deleted if you use the Uninstall All Components option on the Cisco Aironet Wireless 
LAN Client Adapter Installation Wizard screen to uninstall the client adapter software. Cisco 
recommends that you use the Profile Manager’s export feature to save your profiles before uninstalling 
the software.
