21 ASUS WLAN mini-PCI card ReferenceChapter 34.5 Config - Encryption TabLets you configure the ASUS WLAN mini-PCI card encryption settings.For data confidentiality in a wireless environment, IEEE 802.11 specifies aWired Equivalent Privacy (WEP) algorithm to offer transmission privacysimilar to wired network. The WEP uses keys to encrypt transmitted datapackets and decrypt received data packets. The encryption process canscramble frame bits to avoid disclosure to others.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 en-crypt your data before it is transmitted over the air.If you enable WEP encryption, you will only be able to communicate withwireless devices that use the same WEP keys.WEP KeyThis option is enable only if you enable WEP Encryption. The WEP Key isa 64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits that is used toencrypt transmit data packets and decrypt received data packets.

ASUS WLAN mini-PCI card 22 ReferenceChapter 3Key FormatYou can enter the WEP Key as Hexadecimal digits (0~9, a~f, and A~F), oras ASCII characters, based on the state of the Key Format.Key LengthFor 64 bits encryption, each Key contains exactly 10 hex digits, or 5 ASCIIcharacters. For 128 bits encryption, each Key contains exactly 26 hex dig-its, or 13 ASCII characters.Two ways to assign WEP keysManual Assignment – When you click this button, the cursor appears inthe field for Key 1. For 64-bit encryption, you are required to enter fourWEP 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. EachKey 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 Utilityuses an algorithm to generate four WEP Keys for encryption.NOTE: This function eases users from having to remember theirpasswords and is compatible to some existing WLAN utilities, butthis is not very secure. “Manual Assignment” is more secure.Default Key – The Default Key field lets you specify which of the fourencryption 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 rightof this field, selecting the number of the key you want to use, and thenclicking the Apply button. As long as the Access Point or station with whichyou are communicating has the same key in the same position, you can useany of the keys as the default.Click the Apply button to create your encryption keys. After you click theApply button, the “Wireless Settings” utility uses asterisks to mask yourkeys.Click Apply to save and activate the new configurations.

23ASUS WLAN mini-PCI card ReferenceChapter 364/128bits versus 40/104bitsYou may be confused about configuring WEP encryption, especially whenusing multiple wireless LAN products from different vendors. There aretwo levels of WEP Encryption: 64 bits and 128 bits.First, 64 bit WEP and 40 bit WEP are the same encryption method and caninteroperate in the wireless network. This lower level of WEP encryptionuses 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 64bits (40 + 24). Some vendors refer to this level of WEP as 40 bits andothers refer to this as 64 bits. ASUS WLAN card products use the term 64 bits when referring to this lower level of encryption.Second, 104 bit WEP and 128 bit WEP are the same encryption methodand can interoperate in the wireless network. This higher level of WEPencryption 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 togethermakes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104bits 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.

ASUS WLAN mini-PCI card 24 ReferenceChapter 3NOTE: This page is for advanced users. Do not change these set-tings if you do not fully understand these items.RTS ThresholdDefines the size of packets that the station uses for RTS/CTS handshakeboundary. Setting the minimum size packet too small causes RTS packetsto be sent more often, adding excessive overhead to the network and de-creasing network utilization. However, the more often RTS packets aresent, the more transmission collisions can be avoided. RTS threshold rangesfrom 0 to 2346 in 64 steps.Fragmentation ThresholdDefine the number of bytes used for fragmentation boundary. If the lengthof the data unit exceedsthis parameter , it will be divided into smaller frag-ments for transmission. Each of the fragments is sent independently. Ifthere is a significant interference present, set the fragment size smaller.Otherwise,set the fragment size lar ger. Because send multiple frames leadto overhead on the network.Fragmentation Threshold ranged from 256 to2432 steps 128.4.6 Config - Advanced TabAdvanced tab provides some additional settings for the ASUS WLANmini-PCI card. The “Advanced” tab is hidden until you click Advanced onthe Config - Basic page.

25ASUS WLAN mini-PCI card ReferenceChapter 3Authentication AlgorithmBecause there is no precise bound in wireless LANs, it needs to be imple-mented in another mechanism to provide a higher level of security. That iswhere Authentication services come in. If a mutual authentication relation-ship 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 uponthe ASUS WLAN mini-PCI card Client using WEP encryption or not.Open System – A null authentication algorithm. A station can authenticatewith any other station or Access Point and without checking any WEP Key,even if one exists.Share Key – In a Share Key Authentication system, four-step exchange offrames is required to validate that the station is using the same WEP Key asthe Access Point. Using this Authentication mechanism requires imple-mentation of the WEP option.Maximum Listen IntervalThis value is used to indicate how often a station will wake up to listen tobeacon management frames. Listen intervals range from 0 to 77 in steps of 1.Preamble ModeThis parameter is used to control whether frames will transmit with thelong or short preamble.Click Apply to save and activate the new configurations.
