Create or Modify a Configuration Profile
To add a new configuration profile, click New on the Profile Management tab. To modify a
configuration profile, select the configuration from the Profile list and click the Modify button.
The Profile Management dialog box displays the General tab.
Profile Management:
Edit the General tab.
Edit the Security tab.
Edit the Advanced tab.
To configure a profile for ad hoc or access point (infrastructure) mode, edit the Network Type field
on the Advanced tab.
Note that the ACU only allows the creation of 16 configuration profiles. After the creation of 16
profiles, clicking the New button displays an error message. Remove an old profile or modify an
existing profile for a new use.
Auto Profile Selection Management
Including a profile in the auto selection feature allows the wireless adapter to automatically select
that profile from the list of profiles and use it to connect to the network.
Including a profile in auto profile selection:
1. On the Profile Management tab, click the Order Profiles button.
2. The Auto Profile Selection Management window appears, with a list of all created profiles
in the Available Profiles box.

15
3. Highlight the profiles to add to auto profile selection, then click Add. The profiles appear in
the Auto Selected Profiles box.
Ordering the auto selected profiles:
1. Highlight a profile in the Auto Selected Profiles box.
2. Click Move Up, Move Down, or Remove as appropriate.
The first profile in the Auto Selected Profiles box has highest priority, and the last profile
has lowest priority.
3. Click OK.
4. Check the Auto Select Profiles box.
5. Save the modified configuration file.
When auto profile selection is enabled by checking Auto Select Profiles on the Profile
Management tab, the client adapter scans for an available network. The profile with the
highest priority and the same SSID as one of the found networks is the one that is used to
connect to the network. If the connection fails, the client adapter tries the next highest
priority profile that matches the SSID, and so on.
With auto profile selection enabled, the wireless adapter scans for available networks. The highest
priority profile with the same SSID as a found network is used to connect to the network. On a
failed connection, the client adapter tries with the next highest priority profile.

16
Scan Available Networks
Click the Scan button on the Profile Management tab to scan for available infrastructure and ad hoc
networks. On this list, click Refresh to refresh the list at any time.
Connecting to a different network
Highlight a network name and click the Activate button to connect an available network. If
no configuration profile exists for that network, the Profile Management window opens to
the General tab. Fill in the profile name and click OK to create the configuration profile for
that network.

17
Security Tab
In the Client Utility, access the Security tab by clicking New or Modify on the Profile Management
tab. Click the Security tab in the Profile Management window.
Edit the fields in the Security tab of Profile Management to configure the profile. To define the
security mode, select the radio button of the desired security mode. Make sure to also edit the
General and Advanced tabs.
WPA/WPA2 Enables the use of Wi-Fi Protected Access (WPA).
Choosing WPA/WPA2 opens the WPA/WPA2 EAP drop-down menu.
The options include:
EAP-FAST (Extensible Authentication Protocol-Flexible
Authentication via Secure Tunneling )
EAP-FAST is to support customers who cannot enforce a strong
password policy and wish to deploy an 802.1X EAP type that does not
require digital certificates, supports a variety of user and password
database types, supports password expiration and change, and is
flexible, easy to deploy, and easy to manage. For example, a customer
using Cisco LEAP who cannot enforce a strong password policy and
does not want to use certificates can migrate to EAP-FAST for protection
from dictionary attacks. (See help menu on configuration utility for more
details)
EAP-TLS(Extensible Authentication Protocol-Transport Layer
Security) is a Point-to-Point Protocol (PPP) extension supporting
additional authentication methods within PPP. Transport Layer
Security (TLS) provides for mutual authentication, integrity-protected
cipher suite negotiation, and key exchange between two endpoints.
EAP-TTLS (Extensible Authentication Protocol-Tunneled
Transport Layer Security) An EAP variant that provides mutual
authentication using a certificate for server authentication, and via a
secure TLS tunnel for the client
PEAP (EAP-GTC) (Protected Extensible Authentication
Protocol) authenticates wireless LAN clients using only server-side
digital certificates by creating an encrypted SSL/TLS tunnel between
the client and the authentication server. The tunnel then protects the
subsequent user authentication exchange.
PEAP (EAP-MSCHAP V2)(Protected Extensible
Authentication Protocol)To use PEAP (EAP-MSCHAP V2)
security, the server must have WPA-PEAP certificates, and
the server properties must already be set. Check with the IT

18
manager
LEAP (Lightweight and EfficientApplication
Protocol) is the general framework for a set of
high-performance, efficient protocols which are ideal for
mobile and wireless applications. LEAP is designed to
address all the technical requirements of the wireless
data communications industry, and is oriented towards
providing the greatest benefit to the industry and the
consumer
WPA/WPA2
Passphrase Enables WPA/WPA2 Passphrase security.
Click on the Configure button and fill in the WPA/WPA2 Passphrase.
802.1x Enables 802.1x security. This option requires IT administration.
Choosing 802.1x opens the 802.1x EAP type drop-down menu. The
options include:
EAP-FAST
EAP-TLS
EAP-TTLS
PEAP (EAP-GTC)
PEAP (EAP-MSCHAP V2)
LEAP
If the access point that the wireless adapter is associating to has
WEP set to Optional and the client has WEP enabled, make sure that
Allow Association to Mixed Cells is checked on the Security Tab to
allow association.
