Cisco Cisco Aironet 350 Wireless LAN Client Adapter

To minimize the risk of a power failure during the firmware flashing process, which could render 
your client adapter inoperable, Cisco recommends that your computer be plugged into AC power or 
have a fully charged battery at the start of flashing. If a power failure does occur, follow the 
instructions in the 

 section to contact TAC for assistance.

This section describes how to upgrade to client adapter firmware release 5.02.19 on a computer running 
Windows 98, 98 SE, NT, 2000, Me, or XP. Refer to the following document for instructions on upgrading 
the firmware on a Windows CE device:

Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows CE, 
version -03

To find the firmware version that your client adapter is currently using on a computer running Windows 
98, 98 SE, NT, 2000, Me, or XP, open ACU and click the Status icon. The firmware version is displayed 
in the Firmware Version field on the Status screen.

On a Windows 98, 98 SE, NT, 2000, Me, or XP computer, you can upgrade your client adapter’s 
firmware using either the Install Wizard or ACU. If you use the wizard, the firmware loads from the 
Install Wizard file and is installed along with other software components. If you use ACU, the firmware 
installs from an image (*.img) file that contains only firmware.

To ensure compatibility between software components, Cisco recommends that you use the Install 
Wizard to upgrade the firmware along with the other software components.

Firmware version 5.02.19 does not include support for rogue access point detection. If you require 
this feature, use ACU to upgrade to firmware version 5.02.20 after Install Wizard version 1.0 has 
been installed.
