Security
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.
AES
Advanced Encryption Standard is method of data encryption that uses a secret
key. AES may use a 128-bit, 192-bit or 256-bit key. AES is faster than 3DES.
TKIP
Temporal Key Integrity Protocol (TKIP) is an encryption protocol that uses 128-bit
keys that are dynamically generated and distributed by the authentication server.
TKIP regularly changes and rotates the encryption keys so that the same
encryption key is never used twice.
MAC Address Filter
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”.
