Chapter 3 Software Reference Chapter 3 - Software Reference 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 (Maximum power-saving mode), 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. Others Encryption: Click this link to show the "Encryption" tab. Advanced: Click this link to show the "Advanced" tab. In most cases, the default values do not have to be changed. Config - Encryption This page enables you to configure the Wireless LAN 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, WPA-Personal, WPA2-Personal, WPAEnterprise, and WPA2-Enterprise. Open - Select this option to make the network operate on Open System mode, which use no authentication algorithm. Open stations and APs can authenticate with each other without checking any WEP Key, even if there is. 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. 34 ASUS Network adapter
