Important Notes

GINA Error on Bootup

If your computer ever experiences a GINA error on bootup, boot to the safe mode command prompt.

Then copy the msgina.dll file in the WinNT\System32 directory (Windows 2000) or Windows\System32

directory (Windows XP) over to a file named cscogina.dll. The copy command enables you to copy a

source file (msgina.dll) to a destination file (cscogina.dll) within the same directory.

Reboot Required When Uninstalling ACU and ADU

Caution When you uninstall ACU and ADU, make sure you reboot your computer when prompted. Otherwise,

the system may be rendered unable to boot, displaying the message “The Logon User Interface DLL

cswGina.dll failed to load. Contact your system administrator to replace the DLL or restore the original

DLL.”

Uninstalling Software Components

All profiles and stored PAC files are deleted if you use the Uninstall the previous installation option

on the Previous Installation Detected Install Wizard window to uninstall the client adapter software.

Cisco recommends that you use the Profile Manager’s export feature to save your profiles before

uninstalling the software.

Profiles for PC-Cardbus Cards

The profiles for PC-Cardbus cards are tied to the slot in which the card is inserted. Therefore, you must

always insert your PC-Cardbus card into the same slot, create profiles for both slots, or export the

profiles for one slot and import them for the other slot.

Auto Profile Selection Enables Scan of All Wireless Modes

When you enable auto profile selection, the client adapter scans all wireless modes (5 GHz, 54 Mbps;

2.4 GHz, 11 Mbps; and 2.4 GHz, 54 Mbps) for an available network. The client ignores the selected

profile’s wireless mode setting, which was configured on the ADU Profile Management (Advanced)

window. Using this method, the client does not need to drop the current connection nor change the

current profile while looking for networks in other profiles.

ASTU Exit Option

The Exit option on the Aironet System Tray Utility (ASTU) pop-up menu closes both ASTU and ADU.
