client adapter’s green LED blinks.

Refer to the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration 
Guide for Windows CE for information on configuring your client adapter.

This section describes new and changed information for client utility release 2.20 and driver release 2.20 
for Windows CE.

The Cisco Aironet client adapter driver and utilities for Windows CE 3.0 now support handheld PCs 
(HPCs) with SH4 processors.

Windows CE driver version 2.20 supports MIC, a new security feature designed to prevent sophisticated 
attacks on your wireless network’s WEP keys. MIC does not need to be enabled on the client adapter; it 
is supported automatically in the driver version listed above. However, it must be enabled on the access 
point.

MIC prevents bit-flip attacks on encrypted packets. During a bit-flip attack, an intruder intercepts an 
encrypted message, alters it slightly, and retransmits it, and the receiver accepts the retransmitted 
message as legitimate. MIC adds a few bytes to each packet to make the packets tamper-proof.

The ACU screen displays the word “(MIC)” next to the current status if MIC is supported by the client 
adapter’s driver and is enabled on the access point. If MIC is enabled, MIC statistics are provided by the 
Client Statistics Utility (CSU).

Access point firmware version 11.10T or greater is required to enable MIC. Refer to the 
Cisco Aironet Access Point Software Configuration Guide for instructions on enabling MIC 
on the access point.

If you enable MIC on the access point, your client adapter’s driver must support MIC; 
otherwise, the client will not be able to associate.
