Click the [Configuration] link on the left and a drop down menu will appear on the page. Then click the [General] option to continue. The "Access Point Name" is simply used to identify the AP. This is not the Service Set Identifier.
The "ESSID" field represents the wireless workgroup name. Your wireless clients must have the same value configured in their network settings. You can also choose the operating radio channel. In the "Administration Parameters" section, you can change the password required for any administrator to log into this AP. Note that this password is needed to login via both the web interface and the utility application. After changing any parameters, you need to press the [Apply] button on the bottom of the page.
