Using Open Authentication and Static WEP Keys
If you want to learn more about Wireless Security before you start this section, refer to these documents:

This example is based on the use of open authentication and 128−bit static Wired Equivalent Privacy (WEP)
encryption keys.
Caution: It is not recommended to use Shared Key authentication because it is very easy to
compromise.
This task guides you through a very basic Cisco 7920 and Cisco Aironet 1200 AP configuration. This
configuration allows the Cisco 7920 to authenticate and associate with the 1200 AP. When you are done, the
Cisco 7920 should be able to register with the Cisco CallManager server.
Note: When you are using open authentication, the Cisco Aironet 1200 AP will authenticate all devices that
send it authentication requests. However, only devices with the correct WEP encryption keys will be able to
associate with the 1200 AP and to send traffic over it successfully.
Configuring the Cisco 7920
This subtask assumes that you have already installed the Cisco 7920 Configuration Utility that came with
your Cisco 7920. If you have not yet installed this utility, stop and do so now. The instructions for the
installation are included with your Cisco 7920.
