ASUS WLAN Adapter 25Chapter 3 - Software ReferenceChapter 3Software ReferenceCong - BasicThis page enables you to change the WLAN Adapter congurations.Network TypeInfrastructure – Infrastructure means to establish a connection with an access point. Once connected, the access point allows you to access wireless LAN and wired LAN (Ethernet). The Channel eld turns to Auto if the connection is based on Infrastructure.Ad Hoc – Ad Hoc means to communicate directly with other wireless clients without using an access point. An “Ad Hoc” network can be setup quickly and easily without pre-planning, for example, sharing meeting notes between attendants in a meeting room.Network Name (SSID)SSID stands for “Service Set Identier”, which is a string used to identify a wireless LAN. Use the SSID to connect with a known access point. You can enter a new SSID or select one from the drop-down list box. If you get connected by designating the SSID, you are only to connect the AP with the SSID you assigned. If the AP is removed from the network, your WLAN Adapter does not roam automatically to other APs. SSIDs must all be printable characters and having a maximum of 32 case sensitive characters, such as “ Wireless”.ChannelThe Channel eld is for setting radio channel. Your WLAN Adapter can automatically select the correct channel to communicate with a wireless device, and the parameter is xed to "Auto" in both Infrastructure and Ad Hoc mode.The available radio channels depend on the regulations in your country. For the United States (FCC) and Canada (IC), channel 1 to 11 are supported. For Europe (ETSI), channel 1 to 13 are supported. For Japan (MKK), channel 1 to 14 are supported.NOTE: Click Apply to save and activate the new congurations.
26 ASUS WLAN AdapterChapter 3 - Software ReferenceChapter 3Software ReferenceCong - AdvancedClick Advanced link on Cong-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 specic 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 specic 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 BurstingFrame Bursting technology improves wireless network efciency and boosts throughput.PS ModeConstantly 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.Power Saving Polling Mode (PSP 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.OthersEncryption – 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.
ASUS WLAN Adapter 27Chapter 3 - Software ReferenceChapter 3Software ReferenceNetwork AuthenticationSince 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-PSK, WPA, WPA2 and WPA2-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, ve Extensible Authentication Protocol (EAP) are supported, including PEAP, TLS/Smart Card, TTLS, LEAP and Md5-Challenge.Cong - EncryptionThis page enables you to congure the Wireless LAN Adapter encryption settings. For data condentiality in a wireless environment, IEEE 802.11 species 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.
28 ASUS WLAN AdapterChapter 3 - Software ReferenceChapter 3Software ReferenceData encryptionFor Open and Shared authentication mode, the conguration 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 veries the security conguration after the encryption keys are determined.AES: AES is a symmetric 128-bit block encryption technique that works simultaneously on multiple network layers.Wireless Network KeyThis option is enabled only if you select WPA-PSK or WPA2-PSK authentication mode. Select “TKIP” or “AES” in the encryption led as encryption mode to begin the encryption proceed. Note: 8 to 64 characters are required in this eld.Wireless Network Key (WEP)This option is congurable only if you enable WEP in Network Authentication eld. 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 FormatYou can select to enter Hexadecimal digits (0~9, a~f, and A~F) or ASCII characters to setup keys by dening the Key Format.Key LengthFor 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 eld 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).
ASUS WLAN Adapter 29Chapter 3 - Software ReferenceChapter 3Software ReferenceSelect one as your Default KeyThe Default Key eld 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 40/104bitsThere 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 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. 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.
30 ASUS WLAN AdapterChapter 3 - Software ReferenceChapter 3Software ReferenceCong - AuthenticationThis tab allows you to set the security settings to match those of your AP. It is congurable only if you have set Network Authentication to WPA or WPA2 in Cong-Encryption tab.Authentication TypeThe 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.TLS: TLS (Transport Layer Security) authentication is used to create an encrypted tunnel and achieve server-side authentication in a manner similar to Web server authentication using Secure Sockets Layer (SSL) protocol. This method uses digital certicates to verify the identity of a client and server.TTLS: TTLS authentication uses certicates to authenticate the server, while maintaining similar security properties to TLS such as mutual authentication and a shared condentiality for session WEP key.Survey - Site SurveyUse the Site Survey tab to view statistics on the wireless networks available to the WLAN adapter and their parameters. • SSID: The SSID of the available networks.• Channel: The channel used by each network.
