Step 8 Perform one of the following:
• If you selected an SSID from the list of available networks, make sure the SSID appears in the
Network name (SSID) field.
• If you clicked Add, enter the case-sensitive SSID of the access point or the ad hoc network to which
you want the client adapter to associate in the Network name (SSID) field.
Step 9 Check the Data encryption (WEP enabled) check box if you are planning to use static or dynamic WEP.
Step 10 Check the Network Authentication (Shared mode) check box if you want to use shared key, rather than
open, authentication with the access point.
Open authentication enables your client adapter, regardless of its WEP settings, to authenticate and
attempt to communicate with an access point.
Shared key authentication enables your client adapter to communicate only with access points that have
the same WEP key. Cisco recommends that shared key authentication not be used because it presents a
security risk.
Note If you are planning to use EAP-TLS authentication, do not check this check box. EAP-TLS does
not work with shared key authentication because shared key authentication requires the use of a
WEP key, and a WEP key is not set for EAP-TLS until after the completion of EAP
authentication.
