Release Notes for Cisco Aironet MS-DOS Drivers and Utilities for WLAN Client Cards
The Cisco Aironet MS-DOS drivers for WLAN client cards function in the same manner as the MS-DOS drivers for wired NIC's, but they have the need for additional radio parameters. Those additional radio parameters define the WLAN parameters that the radio card must match before it can associate with an access point.
The Cisco MS-DOS drivers for Aironet WLAN client cards are the AWCPKT driver for the IP protocol, the AWCODI driver for the Novell protocol, the AWCNDIS driver for the IBM NetBeui protocol. All three of these drivers support the LM4800, PC4800, LMC340, PC340, LMC350, and the PCM350 cards. This makes the cards interchangeable as far as the driver is concerned. New to the current drivers is support for LEAP, World Mode, and the 350 series client cards. The LM4800, because of hardware limitations, cannot accommodate LEAP. Because LEAP and World Mode are firmware dependent, the client firmware must be upgraded to the latest version.
This document contains the following sections:
This document describes the system requirements, upgrade procedures, new and changed information, and caveats for the following releases of Cisco Aironet software:
•Version 2.04 of MS-DOS drivers for IP, Novell, and NetBeui
•Latest editions of 5 MS-DOS utilities to support various WLAN configurations
Note Version numbers have not been assigned to the MS-DOS Utilities included with this release.
MS-DOS drivers and utilities can be used with only Cisco Aironet 340, 350, 4500, and 4800 Series Wireless LAN Client Adapters (PC , PCI, and LM cards) installed in computing devices running MS-DOS version 6.22, Windows 3.x, or Windows For Workgroups 3.xx.
Upgrading to a New Driver Release
There is no need to uninstall the old driver before upgrading to a new driver. Replace the current NIC driver with the upgraded Cisco Aironet driver, then make the appropriate update to the configuration file.
Loading a New Driver and Utilities
The new driver files replace the previous driver files. Installation is accomplished at the command prompt using standard MS-DOS commands.
The MS-DOS and Windows for Workgroups based drivers must have a configuration file created (or edited) with an ASCII text editor.
The drivers and associated files do not ship with the adapter. You must download them from the Wireless Software Center at Cisco.com. The downloadable file, DOSDRVS.EXE, is a self-extracting executable file containing separate self-extracting executable files for each driver. After downloading and running the DOSDRVS.EXE file, you can run the driver file for your specific application. The UTIL.EXE file must also be run to extract the utility programs for these drivers. The structure of the DOSDRVS.EXE file is shown in Table 1.
