6 Configuring Frequently Used Functions

6.2.3 Using Secure Encryption

Function Overview
To ensure the security of a WLAN, an important solution is to select an optimum security
mode for the WLAN. After this security mode is used, a wireless client should provide
the corresponding password when connecting to the WLAN and data is being
transmitted after secure encryption. Thus, only authorized persons can use the WLAN
and the data transmitted on the WLAN is protected against unauthorized access.
The HG256s supports WEP encryption and multiple security modes, such as WPA-PSK
and WPA2-PSK, thus meeting security requirements in diversified network
environments.
It is recommended that you set the security mode to WPA-PSK/WPA2-PSK and the
encryption mode to AES. Thus, the WLAN works efficiently and the security of the
WLAN is ensured. In addition, if a wireless adapter does not support a certain security
mode, it cannot be connected to the WLAN in this security mode. If you use the
recommended security and encryption modes, this problem can be avoided.

The WPS function can be used only when the security mode is set to WPA-PSK or WPA2-PSK.

AES = Advanced Encryption Standard
Table 6-1 lists the rules for setting the password used for accessing a WLAN in different
