Ad Hoc Mode
In ad hoc mode, a wireless network adapter works within an independent basic service
set (IBSS), as illustrated here. All stations communicate directly with other stations
without using an access point (AP).
To connect to an ad hoc network, configure the profile for ad hoc mode. Ad Hoc
operation may be limited by Hardware to meet regulatory requirements.
Ad Hoc Mode Profile Configuration
To configure a profile in ad hoc mode, change the Network Type in the Profile
Management's Advanced tab. For ad hoc mode, modify the settings:
Network Name (on General Tab)
Transmit Power Level
802.11b Preamble (if using 802.11b)
Wireless Mode When Starting an Ad Hoc Network

Infrastructure (Access Point) Mode
In infrastructure (access point (AP)) mode, the wireless network adapter participates in a
basic service set (BSS) as a station, and communicates with the other stations through an
AP, as illustrated here.
To connect to an access point network, configure the profile for access point mode.
Infrastructure (Access Point) Mode Profile Configuration
To configure a profile in infrastructure (access point) mode, change the Network Type in

Uninstall an Old Driver
Uninstall an old driver before upgrading to a new NDIS driver release.
To remove the newly installed driver from the system if the system does not have
previously installed versions of the NDIS driver, proceed to Step 4.
1. To remove the NDIS driver from the OS, go to Device Manager, right-click Acer
AR500x Wireless Network Adapter, and choose Uninstall.
2. Click OK to uninstall the device.
3. When the device is uninstalled from Device Manager, search for and delete the
driver files that reside in the system.
a. Go to the Start menu and choose Search > For Files or Folders.
b. Enter oem*.inf in the Search for files or folders named: field, and enter Acer
in the Containing text: field.
c. Click Search Now. A few files matching these criteria are possible, if previous
drivers have not been removed properly.
d. Choose the files that have been found and delete them from the system.
4. To complete the uninstallation, remove the file ar5211.sys from the folder
\WINNT\system32\drivers.
Additional Security Features
These security features prevent attacks on a wireless network's WEP keys. The wireless
adapter automatically supports each of these features, but these features must be enabled
on the access point.
Message Integrity Check (MIC)
MIC prevents bit-flip attacks on encrypted packets. In a bit-flip attack, someone
intercepts an encrypted message retransmits it after some alterations. Thus the receiver
accepts the message as legitimate. The MIC adds some bytes to each packet to protect it
against tampering.
Temporal Key Integrity Protocol (TKIP)
This feature prevents attacks on WEP in which someone catches encrypted packets and
uses their initialization vector (IV) to decipher the WEP key. TKIP removes the
predictability to protect both unicast and broadcast WEP keys.
Broadcast Key Rotation
EAP authentication provides dynamic unicast WEP keys for wireless adapters, but uses
static broadcast keys. In broadcast WEP key rotation, the access point supplies a
dynamic broadcast WEP key and changes it at intervals.
Advanced Status Information
Click the Advanced button on the Current Status tab of the Acer Client Utility to see
advanced information about the program and its operations. The Current Status tab does
not require any configuration. The following table describes the items found on the
Advanced Status screen.
Network Name (SSID) Displays the wireless network name.
Configure the network name on the General tab.
Server Based Shows whether server based authentication is used.
Authentication
Data Encryption Displays the encryption type the driver is using. Configure the
encryption type on the Security tab.
Authentication Type Displays the authentication mode.
Configure the authentication mode on the General tab.
Message Integrity Shows whether MIC is enabled. MIC prevents bit-flip attacks on
Check encrypted packets.
Associated AP Name Displays the name of the access point the wireless adapter is
associated to.
Associated AP IP Shows the IP address of the access point the wireless adapter is
Address associated to.
Associated AP MAC Displays the MAC address of the access point the wireless
Address adapter is associated to.
Power Save Mode Shows the power save mode. Power management is disabled in
ad hoc mode.
