Configuring Wireless Security

This chapter covers the configuration of security options in the ZyXEL Utility.

4.1Configuring Security

You can configure your security settings at any time. Simply select the wireless AP/Router found under Site Survey, double click to land the Profile Configuration screen and then select [Security]. You are also presented with the option to configure security under the Profile creation process and double click the AP/Router you will connect to and then select [Security]. Whether changing the security settings of an existing profile or creating a new profile, the steps to configure your security settings remain the same. You also need to know the security settings of the AP/Router you will connect to and follow its setting.

When you configure the following security settings, you need to check and follow

your AP/Router settings. If your adapter’s setting is not complied with the

AP/Router, it will fail to connect the network.

In addition, for users who need enhanced security settings for WPA, WPA-PSK and 802.1x as well as connecting from the wireless client to the corporate RADIUS server, you need to install Funk Odyssey Client software as well. Please see the User Guide of Funk Odyssey Client software.
