Authentication and Security
The Security tab allows you to configure the authentication and encryption
settings such as: WEP, WPA, WPA-PSK, WPA2, and 802.1x. Each security
option is described in detail below.
WEP Encryption
The WEP tab displays the WEP settings. Encryption is designed to make the
data transmission more secure. You may select 64 or 128-bit WEP (Wired
Equivalent Privacy) key to encrypt data (Default setting is Disable). WEP
encrypts each frame transmitted from the radio using one of the Keys from a
panel. When you use WEP to communicate with the other wireless clients, all the
wireless devices in this network must have the same encryption key or pass
phrase. The following information is included in this tab, as the image depicts
below.
WiFi Alliance certification recommends WPA2 AES to be the security
mechanism under 11N mode. System driver will automatically bring down
wireless data rate to 54Mbps if other security method such as WEP or WPA is
used under 11n mode.
If your 11N router is using security mechanism other than WPA2 AES, you
are recommended to disable security setting or change it to WPA2 AES to fully
utilize 11N capability. This policy has no effect if connecting with b/g only
wireless access point.
