Cisco Cisco Aironet 350 Wireless LAN Client Adapter

The existing Mac OS drivers (version 1.0.2 and earlier for Mac OS 9.x and version 1.0.0 for Mac OS 
10.1) are not compatible with firmware version 4.25.23. If you install firmware version 4.25.23 on 
your client adapter and use it with an existing Mac OS driver, you will be unable to use some of the 
adapter’s capabilities, such as WEP and LEAP.

Although firmware version 4.25.23 is compatible with Windows CE and Linux, the latest drivers for 
these operating systems (version 1.70 for Windows CE and version 1.5.2 for Linux) do not support 
the message integrity check (MIC) and temporal key integrity protocol (TKIP) security features 
supported in this firmware release. Currently the only driver that supports MIC and TKIP is Windows 
driver version 8.01.06.

You must have a Cisco Aironet 340, 350, or 4800 series PC card, LM card, or PCI client adapter to install 
firmware version 4.25.23.

To take advantage of the security features introduced in client adapter firmware release 4.25.23, you 
must install Windows ACU version 5.01.001 or greater and Windows driver version 8.01.06 or greater 
(or Windows mini PCI driver version 2.20 or greater), and you must use access point firmware version 
11.10T or greater.

In order to use Network-EAP authentication on your wireless network, your client devices and 
infrastructure devices (access points and bridges) must use the same 802.1X protocol draft. Client 
firmware release 4.25.23 supports draft 10 of the 802.1X protocol standard. Therefore, if client devices 
use this version of firmware, an access point or bridge to which they associate must also be configured 
to use draft 10. The table below lists firmware versions for Cisco Aironet products and the drafts with 
which they comply.
