4-6ASUS WiFi-b™ CardConfig - EncryptionTabWireless data transmissions betweenyour WiFi-b™ and the AP are securedusing the Wired Equivalent Privacy(WEP) encryption. Check the Dataencryption (WEP enabled) option toassign the WEP keys.Check the Network Authentication(Shared Mode) option if you wish to usea network key to authenticate a preferredwireless network. Unchecking this optionallows the network to operate on anOpen System mode.Key Format allows you to set a hexadecimal digit or ASCII character WEP key.Key Length allows you to choose a 64-bit or a 128-bit WEP key. A 64-bitencryption contains 10 hexadecimal digits or 5 ASCII characters. A 128-bitencryption contains 26 hexadecimal digits or 13 ASCII characters.64-bit and 40-bit WEP keys use the same encryption method and can interoperateon wireless networks. This lower level of WEP encryption uses a 40-bit (10hexadecimal digits assigned by the user) secret key and a 24-bit Initialization Vectorassign by the WiFi-b™. 104-bit and 128-bit WEP keys use the same encryptionmethod.Network Name - Displays the network SSID. The network SSID is a string use toidentify a wireless LAN. Assign different SSIDs to segment the wireless LAN andincrease network security. Set the SSID to a null string to allow your station toconnect to any available access point. Null string may not be used in Ad Hocmode.Channel. In Infrastructure mode, WiFi-b™ automatically tunes in to the accesspoint channel. In Ad Hoc mode, select a channel that is allowed for use in yourcountry/region. See the Appendix for channel information.Data Rate. Select Fully Auto to allow WiFi-b to adjust to the most suitableconnection. You may also fix data transfer rates to 11, 5.5, 2 and 1 Mbps.PS Mode. This field allows control of the WiFi-b™ card power saving features. TheCAM (Constantly Awake mode) is recommended for systems running on ACpower. Other options include MAX_PSP (Maximum Power Savings) and Fast_PSP(Fast power-saving mode)Others. Click the WEP or Advanced link to open the Encryption or Advancedproperty tab sheet.All wireless clients in a network must have identical WEP keys to communicate witheach other or with an access point.
Chapter 4: Utility information4-7Two ways to assign WEP keysManual Assignment. For a 64-bit encryption, enter 10 hexadecimal digits (0~9,a~f, A~F) or 5 ASCII characters in each of the four WEP keys. For 128-bitencryption enter 26 hexadecimal digits (0~9, a~f, A~F) or 13 ASCII characters ineach of the four WEP keys.Automatic Generation. Type a combination of up to 64 letters, numbers, orsymbols in the Passphrase field. The Wireless Settings utility uses an algorithm togenerate four WEP keys based on the typed combination.•After assigning the WEP keys, click APPLY to save and activate the encryption.Manually assigned encryptions are more secure than automatically generatedencryptions.•Use Manual Assignment instead of Automatic Generation if you are not surewhether other wireless clients use the same algorithm as that of WiFi-b™.•Keep a record of the WEP encryption keys.Config - AdvancedThe Advanced tab displays the WiFi-b™card advance settings.
