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 Selectio n Management window appears, with a list of all created profiles
in the Available Profiles box.
3. Highlight the profiles to add to auto profile selection, and then click Add. The profiles
appear in the Auto Selected Profiles box.
Ordering the auto selected profiles:
Highlight a profile in the Auto Selected Profiles box.

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.

Choosing WPA opens the WPA 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
