Security
Following is the detailed introduction of security mode: WPA/WPA2 and WPA-PSK/WPA2-
PSK.
 WPA-PSK/WPA2-PSK
Based on pre-shared key. It is characterized by higher safety and simple settings, which
suits for common households and small business. WPA-PSK has two versions: WPA-PSK
and WPA2-PSK.

 WPA/WPA2
Based on Radius Server, WPA can assign different passwords for different users and it is
much safer than WPA-PSK. However, it has high maintenance costs and is only suitable for
enterprise users. At present, WPA has two versions: WPA and WPA2.
Specify the security option of the wireless network. If all the clients are allowed
to access the wireless network, please select None. For the safety of the
wireless network, you are suggested to encrypt your wireless network with
password. This device provides three security options: WPA/WPA2 (Wi-Fi
Protected Access) and WPA-PSK/WPA2-PSK (WPA Pre-Shared Key). WPA-
PSK/WPA2-PSK is recommended. Settings vary in different security options as
the details is in the following introduction.
Select one of the following versions:
Auto: Select WPA or WPA2 automatically based on the wireless client's
capability and request.
WPA-PSK: Pre-shared key of WPA.
WPA2-PSK: Pre-shared key of WPA2.
Select the encryption type, including Auto, TKIP, and AES. The default setting is
Auto, which can select TKIP (Temporal Key Integrity Protocol) or AES (Advanced
Encryption Standard) automatically based on the wireless station's capability
and request. AES is more secure than TKIP and TKIP is not supported in
802.11n mode. It is recommended to select AES as the encryption type.
Enter the number of seconds (minimum 30) to control the time interval for the
encryption key automatic renewal.
Configure the PSK password with ASCII or Hexadecimal characters. For ASCII,
the length should be between 8 and 63 characters with a combination of
numbers, letters (case-sensitive) and common punctuations. For Hexadecimal,
the length should be 64 characters (case-insensitive, 0-9, a-f, A-F).
