MAX-207HW2R User’s Guide

Security stops unauthorized devices from using the wireless network. It can also 
protect the information that is sent in the wireless network.Use the strongest 
security that every wireless client in the wireless network supports.

Note: WPA2 or WPA2-PSK security is recommended.

• WPA2-PSK and WPA-PSK do not employ user authentication and are known as 

the personal version of WPA.

• WEP is better than no security, but it is still possible for unauthorized devices to 

figure out the original information pretty quickly.

Every Ethernet device has a unique MAC (Media Access Control) address. The MAC 
address consists of twelve hexadecimal characters (0-9, and A to F), and it is 
usually written in the following format: “0A:A0:00:BB:CC:DD”. 

The MAC filter controls access to the wireless network. You can use the MAC 
address of each wireless client to allow or deny access to the wireless network.

• See 

 for advanced technical information on wireless 

networks.
