Advanced - Click on this to show the "Advanced" tab. In most cases, the default values do not have to be changed. Troubleshooting. - Click on this to show the "Troubleshooting" utility. ASUS WLAN mini-PCI card 20 Reference 4.5 Config - Encryption Tab Lets you configure the ASUS WLAN mini-PCI card encryption settings. For data confidentiality in a wireless environment, IEEE 802.11 specifies a Wired Equivalent Privacy (WEP) algorithm to offer transmission privacy similar to wired network. The WEP uses keys to encrypt transmitted data packets and decrypt received data packets. The encryption process can scramble frame bits to avoid disclosure to others. Chapter 3 Data encryption (WEP enabled) This option allows you to enable or disable the Wired Equivalent Privacy (WEP) function. If this check box is selected, a WEP Key is used to encrypt your data before it is transmitted over the air. If you enable WEP encryption, you will only be able to communicate with wireless devices that use the same WEP keys. WEP Key This option is enable only if you enable WEP Encryption. The WEP Key is a 64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits that is used to encrypt transmit data packets and decrypt received data packets. 21 ASUS WLAN mini-PCI card Reference Key Format You can enter the WEP Key as Hexadecimal digits (0~9, a~f, and A~F), or as ASCII characters, based on the state of the Key Format. Key Length For 64 bits encryption, each Key contains exactly 10 hex digits, or 5 ASCII characters. For 128 bits encryption, each Key contains exactly 26 hex digits, or 13 ASCII characters. Chapter 3 Two ways to assign WEP keys Manual Assignment – When you click this button, 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). Automatic Generation – Type a combination of up to 64 letters, numbers, or symbols in the Passphrase column, then the Wireless Settings Utility uses an algorithm to generate four WEP Keys for encryption. NOTE: This function eases users from having to remember their passwords and is compatible to some existing WLAN utilities, but this is not very secure. “Manual Assignment” is more secure. Default Key – The Default Key field lets you specify which of the four encryption keys you wish to use to transmit data on your wireless LAN. You can change the default key by clicking on the down arrow at the right of this field, selecting the number of the key you want to use, and then clicking the Apply button. As long as the Access Point or station with which you are communicating has the same key in the same position, you can use any of the keys as the default. Click the Apply button to create your encryption keys. After you click the Apply button, the “Wireless Settings” utility uses asterisks to mask your keys. Click Apply to save and activate the new configurations. ASUS WLAN mini-PCI card 22 Reference 64/128bits versus 40/104bits You may be confused about configuring WEP encryption, especially when using multiple wireless LAN products from different vendors. There are two levels of WEP Encryption: 64 bits and 128 bits. First, 64 bit WEP and 40 bit WEP are the same encryption method and can interoperate in the wireless network. This lower level of WEP encryption uses a 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. ASUS WLAN card products use the term 64 bits when referring to this lower level of encryption. Chapter 3 Second, 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. ASUS WLAN card products use the term 128 bits when referring to this higher level of encryption. 23 ASUS WLAN mini-PCI card Reference 4.6 Config - Advanced Tab Chapter 3 Advanced tab provides some additional settings for the ASUS WLAN mini-PCI card. The “Advanced” tab is hidden until you click Advanced on the Config - Basic page. NOTE: This page is for advanced users. Do not change these settings if you do not fully understand these items. RTS Threshold Defines the size of packets that the station uses for RTS/CTS handshake boundary. Setting the minimum size packet too small causes RTS packets to be sent more often, adding excessive overhead to the network and decreasing network utilization. However, the more often RTS packets are sent, the more transmission collisions can be avoided. RTS threshold ranges from 0 to 2346 in 64 steps. Fragmentation Threshold Define the number of bytes used for fragmentation boundary. If the length of the data unit exceedsthis parameter , it will be divided into smaller fragments for transmission. Each of the fragments is sent independently. If there is a significant interference present, set the fragment size smaller. Otherwise,set the fragment size lar ger. Because send multiple frames lead to overhead on the network.Fragmentation Threshold ranged from 256 to 2432 steps 128. ASUS WLAN mini-PCI card 24 Reference Authentication Algorithm Because there is no precise bound in wireless LANs, it needs to be implemented in another mechanism to provide a higher level of security. That is where Authentication services come in. If a mutual authentication relationship has not been established between the ASUS WLAN mini-PCI card(s) and the Access Point(s), an association cannot be established. Auto based on WEP setting – Switch the authentication mode based upon the ASUS WLAN mini-PCI card Client using WEP encryption or not. Open System – A null authentication algorithm. A station can authenticate with any other station or Access Point and without checking any WEP Key, even if one exists. Chapter 3 Share Key – 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. Using this Authentication mechanism requires implementation of the WEP option. Maximum Listen Interval This value is used to indicate how often a station will wake up to listen to beacon management frames. Listen intervals range from 0 to 77 in steps of 1. Preamble Mode This parameter is used to control whether frames will transmit with the long or short preamble.
