any wireless networking device that is within range.

The following table describes the labels in this screen.
9.2.2  More Secure (Recommended)
The WPA-PSK (WiFi Protected Access-Pre-Shared Key) security mode provides both improved data 
encryption and user authentication over WEP. Using a pre-shared key, both the Zyxel Device and the 
connecting client share a common password in order to validate the connection. This type of 
encryption, while robust, is not as strong as WPA, WPA2 or even WPA2-PSK. The WPA2-PSK security mode 
is a more robust version of the WPA encryption standard. It offers better security, although the use of PSK 
makes it less robust than it could be.
Click Network Setting > Wireless to display the General screen. Select More Secure as the security level. 
WPA2-PSK is the default Security Mode.
Security Mode Select More Secure (Recommended) to add security on this WiFi network. The WiFi clients which 
want to associate to this network must have same WiFi security settings as the Zyxel Device. 
When you select to use a security, additional options appears in this screen.
Or you can select No Security to allow any client to associate this network without any data 
encryption or authentication.
