Configuring the Access Point as an Authenticator
The access point, when acting as an authenticator, receives requests
from end devices that want to communicate with the network and
forwards these requests to the authentication server. It also distributes
the WEP keys to end devices that are communicating with it. Before you
configure the access point as an authenticator, the access point should
be installed and configured to communicate with the wireless end
devices.
To configure the access point as an authenticator
1. From the Main Menu, select Security and then select the radio
security that you are configuring. A screen similar to the one below
appears.
2. Check WEP/802.1x Authentication.
3. Select Submit Changes.
4. In the WEP Key Rotation Period field, enter how often (in minutes) the
access point generates a new WEP key to distribute to the end
devices.
