PS Mode
Constantly Awake Mode (CAM), also known as Disable Power Saving Mode, is a
full powered state that yields the best performance. We recommend this mode for
devices running on AC power.
Max PSP/Fast PSP, which is also known as Enable Power Saving mode,
periodically wakes up the system to check if there is any data being sent. We
recommend this mode for devices running on battery power.

Config - Encryption
This page enables you to configure the network
adapter encryption settings. For data confidentiality
in a wireless environment, IEEE 802.11 specifies a
Wired Equivalent Privacy (WEP) algorithm to offer
transmission privacy. The WEP uses keys to encrypt
and decrypt data packets. The encryption process
can scramble frame bits to avoid disclosure to others.
The WPA-Personal/WPA2-Personal is improved
security system for 802.11 which are developed to
overcome the weakness of the WEP protocol.
Network Authentication
Since there is no precise bound in wireless LANs, the WLAN users need to
implement certain mechanism to provide security solution. The Authentication
policies in this tab provide protection of different levels such as Open, Shared, and
WPA-Personal/WPA2-Personal.
• Open: Select this option to make the network operate on Open System mode,
which does not use an authentication algorithm. A station can authenticate with
any other station or Access Point without checking for any WEP key, even if
one exists.
• Shared: Select this option to make the network operate on Shared key mode.
In a Share Key Authentication system, four-step exchange of frames is required
to validate that the station is using the same WEP Key as the access point.
• WPA-Personal/ WPA2-Personal: Select this option to enable WPA Pre-Shared
Key under Infrastructure mode. It enables communication between your client
and APs using WPA-Personal/WPA2-Personal encryption mode.
