Step 11
WEP.
Check the Network Authentication (Shared mode) check box if you want to use shared key (rather than
Step 12
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
Perform one of the following:

If you are planning to use EAP-TLS or PEAP, which uses dynamic WEP keys, check the The Key

Configure Network Authentication Screen
If you are planning to use EAP-TLS authentication, do not select 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.
Uncheck the The Key is provided for me automatically check box.
Obtain the WEP key for the access point (in an infrastructure network) or other clients (in an ad
hoc network) from your system administrator.
