Cisco Cisco Aironet 350 Wireless LAN Client Adapter

This release introduces the new features discussed inthe “New Features” section on page 3 and resolves 
the caveats listed in the “Resolved Caveats” section on page 5.

Release 1.5.x of the Cisco Aironet client utilities can be used with only Cisco Aironet 340, 350, 4500, 
and 4800 Series Wireless LAN Adapters (PC cards, LM cards, and PCI client adapters) and Linux kernel 
version 2.2.xx or 2.4.xx.

Please read the following important notes before installing and using the latest client utilities.

The /etc/ethX.cfg files in previous versions of ACU are not compatible with version 1.5.6 and can cause 
problems if ACU finds them and attempts to load them. Please remove any old /etc/ethX.cfg files prior 
to running ACU version 1.5.6 for the first time.

The supplied default ethX.cfg file contains a power setting of 30 mW for compatibility between Cisco 
Aironet 340 and 350 Series Wireless LAN Adapters. For 350 series client adapters, use ACU if you want 
to set a higher power level.

If you use LEAP authentication, be advised that the LEAP credentials (username and password) are not 
stored in the /etc/ethX.cfg files. Even though the client may be configured through the bcard utility to 
associate to a LEAP-enabled access point, the client will not LEAP authenticate. To authenticate, either 
manually restart ACU and enter your LEAP credentials via the Commands > Set LEAP Information 
menu option or use one of the new LEAP credential utilities.

One possible solution is to set the LEAP credentials via the bcard and leapscript utilities. 
To do so, add a line after the call to bcard that calls leapscript with your username and 
password.
