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. Software Reference Config - Advanced Chapter 3 Click Advanced link on Config-Basic page to show this tab. This tab allows you to set up additional parameters for the wireless Adapter. We recommend using the default values for all items in this window. RTS Threshold (0-2347) The RTS/CTS (Request to Send/Clear to Send) function is used to minimize collisions among wireless stations. When RTS/CTS is enabled, the router refrains from sending a data frame until another RTS/CTS handshake is completed. Enable RTS/CTS by setting a specific packet size threshold. The default value (2347) is recommended. Fragmentation Threshold (256-2346) Fragmentation is used to divide 802.11 frames into smaller pieces (fragments) that are sent separately to the destination. Enable fragmentation by setting a specific packet size threshold. If there is an excessive number of collisions on the WLAN, experiment with different fragmentation values to increase the reliability of frame transmissions. The default value (2346) is recommended for normal use. Frame Bursting Frame Bursting technology improves wireless network efficiency and boosts throughput. 26 ASUS WLAN Adapter

Chapter 3 - Software Reference 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/WPA2 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 Software Reference protection of different levels such as Open, Shared, WPA-PSK, WPA, WPA2 and WPA2- Chapter 3 PSK. 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. WPA-PSK/ WPA2-PSK - Select this option to enable WPA Pre-Shared Key under Infrastructure mode. It enables communication between your client and APs using WPA-PSK/WPA2-PSK encryption mode. WPA/ WPA2 - The network is operating in IEEE 802.1x authentication mode. This mode is for environments with RADIUS (Remote Access Dial-in User Service). In a RADIUS environment, five Extensible Authentication Protocol (EAP) are supported, including PEAP, TLS/Smart Card, TTLS, LEAP and Md5- Challenge. ASUS WLAN Adapter 27

Chapter 3 - Software Reference Data encryption For Open and Shared authentication mode, the configuration options of encryption type are Disabled and WEP. For WPA, WPA-PSK, WPA2 and WPA2-PSK authentication mode, Temporal Key Integrity Protocol (TKIP) encryption and Advanced Encryption Standard (AES) encryption are supported. Disabled - Disable the encryption function. WEP - WEP Key is used to encrypt your data before it is transmitted over air. You can only connect and communicate with wireless devices that use the same WEP keys. TKIP - TKIP uses an encryption algorithm method that is more stringent than the WEP algorithm. It also uses existing WLAN calculation facilities to perform encryption. TKIP verifies the security configuration after the encryption keys are determined. Software Reference AES: AES is a symmetric 128-bit block encryption technique that works simultaneously on multiple network layers. Chapter 3 Wireless Network Key This option is enabled only if you select WPA-PSK or WPA2-PSK authentication mode. Select “TKIP” or “AES” in the encryption filed as encryption mode to begin the encryption proceed. Note: 8 to 64 characters are required in this field. Wireless Network Key (WEP) This option is configurable only if you enable WEP in Network Authentication field. The WEP Key is a 64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits which is used to encrypt and decrypt data packets. Key Format You can select to enter Hexadecimal digits (0~9, a~f, and A~F) or ASCII characters to setup keys by defining the Key Format. Key Length For 64 bits encryption, each key contains 10 hex digits or 5 ASCII characters. For 128 bits encryption, each key contains 26 hex digits or 13 ASCII characters. Manual assign WEP keys - When you select this option, the cursor appears in the field for Key 1. For 64-bit encryption, you are required to enter four WEP Keys. Each Key contains exactly 10 hex digits (0~9, a~f, and A~F). For 128-bit encryption, you are required to enter four WEP Keys. Each Key contains exactly 26 hex digits (0~9, a~f, and A~F). 28 ASUS WLAN Adapter

Chapter 3 - Software Reference Select one as your Default Key The Default Key field allows you specify which of the four encryption keys is to use for transmitting data over wireless LAN. You can change the default key by clicking on the downward arrow, selecting the number of the key you want to use, and clicking the “Apply” button. If the access point or station with which you are communicating uses the identical key by the same sequence, you can use any of the keys as the default on your WLAN Adapter. Click the “Apply” button after you have created the encryption keys, the Wireless Settings Utility uses asterisks to mask your keys. 64/128bits versus 40/104bits There are two levels of WEP Encryption: 64 bits and 128 bits. Firstly, 64 bit WEP and 40 bit WEP are the same encryption method and can Software Reference interoperate in the wireless network. This lower level of WEP encryption uses a Chapter 3 40 bit (10 Hex character) as a “secret key” (set by user), and a 24 bit “Initialization Vector” (not under user control). This together makes 64 bits (40 + 24). Some vendors refer to this level of WEP as 40 bits and others refer to this as 64 bits. Our Wireless LAN products use the term 64 bits when referring to this lower level of encryption. Secondly, 104 bit WEP and 128 bit WEP are the same encryption method and can interoperate in the wireless network. This higher level of WEP encryption uses a 104 bit (26 Hex character) as a “secret key” (set by user), and a 24 bit “Initialization Vector” (not under user control). This together makes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104 bits and others refer to this as 128 bits. Our Wireless LAN products use the term 128 bits when referring to this higher level of encryption. ASUS WLAN Adapter 29

Chapter 3 - Software Reference Config - Authentication This tab allows you to set the security settings to match those of your AP. It is configurable only if you have set Network Authentication to WPA or WPA2 in Config-Encryption tab. Authentication Type The authentication type methods include: PEAP: PEAP (Protected Extensible Authentication Protocol) authentication is a version of Extensible Authentication Protocol (EAP). EAP ensures mutual authentication between a wireless client and a server that resides at the network operations center. Software Reference TLS: TLS (Transport Layer Security) authentication is used to create an encrypted tunnel and achieve server-side authentication in a manner similar Chapter 3 to Web server authentication using Secure Sockets Layer (SSL) protocol. This method uses digital certificates to verify the identity of a client and server. TTLS: TTLS authentication uses certificates to authenticate the server, while maintaining similar security properties to TLS such as mutual authentication and a shared confidentiality for session WEP key.
