6 ASUS 802.11g WL-HDD2.5Wireless PerformanceThis section provides a few ideas to help you improve the perfor-mance of your WLAN.Site TopographyFor optimal performance, locate wireless mobile clients and the ASUS WL-HDD2.5 away from transformers, heavy-duty motors, flu-orescent lights, microwave ovens, refrigerators, and other industrial equipment. Signal loss can occur when metal or concrete walls or floors block transmission. Locate the ASUS WL-HDD2.5 in open areas or add more devices (APs) as needed to improve coverage.Microwave ovens operate in the same frequency band as the ASUS WL-HDD2.5. Therefore, if you use a microwave oven within range of your device, you may notice network performance degradation. How-ever, your microwave oven and ASUS WL-HDD2.5 will continue to function.RangeEvery environment is unique with different obstacles, barriers, mate-rials, and so on. Therefore, it is difficult to determine the exact range of your WLAN without testing in the specific environment. However, you can follow some of the guidelines described in this section to esti-mate the range of your network. Radio signals may be reflected by some obstacles or absorbed by oth-ers depending on their construction. For example, with two 802.11b radios, you may achieve clear reception over a distance of up to 1000 feet in open spaces, with the two devices being in line of sight (mean-ing they have no obstacles in a straight line between them). However, the same two units may only achieve up to 300 feet of range when used indoors.By default, the ASUS WL-HDD2.5 automatically adjusts the data rate to maintain a usable signal connection. Therefore, a client that is close to the ASUS WL-HDD2.5 may operate at higher speeds while a client that is on the fringe of coverage may operate at lower speeds.
ASUS 802.11g WL-HDD2.5 7You can configure the data rates used by the ASUS WL-HDD2.5 to improve the performance. However, if you limit the range of data rates available to the ASUS WL-HDD2.5, you may reduce the effec-tive wireless range of the WLAN coverage.Site SurveysA site survey (utility provided with ASUS WLAN cards) analyzes the installation environment and provides users with recommendations for equipment and its placement. The optimum placement differs depending on the ASUS AP design and specifications.Roaming Between ASUS APsIf there are multiple ASUS APs on the network, then a wireless mobile client may seamlessly roam from one ASUS AP to another.Each ASUS AP creates its own wireless cell or coverage area. This is also known as a Basic Service Set (BSS). Any wireless mobile client can communicate with a particular ASUS AP if it is within the ASUS AP’s coverage area.If the cells of multiple ASUS APs overlap, then the wireless mobile client may switch from one ASUS AP to another as it travels through-out the building. During the hand-off from one ASUS AP to another, the wireless mobile client maintains an uninterrupted connection to the network. This is known as “roaming.”Multiple ASUS APs connected to a common Ethernet network form an Extended Service Set (ESS). All members of an Extended Service Set are configured with an ID, known as the SSID or ESSID. Wireless mobile clients must be configured with the same SSID as the ASUS APs on the network; a client can only roam between ASUS APs that share the same SSID.
8 ASUS 802.11g WL-HDD2.5Roaming Guidelines• An ASUS WLAN card can only roam between APs of the same type.• All ASUS APs must have the same SSID.• All ASUS WLAN cards must have the same SSID as the APs that they will roam between.• If WEP encryption is enabled, then all ASUS APs and client adapters must use the same encryption level and WEP Key(s) to communicate.• ASUS APs’ cells must overlap to ensure that there are no gaps in coverage and to ensure that the roaming client will always have a connection available.• ASUS APs that use the same Channel should be installed as far away from each other as possible to reduce potential interference.• It is strongly recommended that you perform a site survey using the utility provided with the ASUS WLAN card to determine the best location for each ASUS AP in the building.

46 ASUS 802.11g WL-HDD2.5InterfaceThe Interface submenu has the following options:Region: Scroll through this drop-down box to select the appropriate region where you are located.SSID: The SSID is an identification string of up to 32 ASCII charac-ters unique to every AP. The SSID is also referred to as the “ESSID” or “Extended Service Set ID.” By default, the SSID is set to
ASUS 802.11g WL-HDD2.5 47“WL-HDD”. All the wireless clients in the vicinity must have the same SSID in order to use the ASUS WL-HDD2.5. This field is also used as the device name when you are looking for the ASUS WL-HDD2.5 through the Windows Network Neighborhood function.Channel: The 802.11g and 802.11b specification supports up to 14 overlapping channels for radio communication. Choose an appropri-ate channel for the operating radio frequencies or choose Auto to select a channel automatically. The available channels change accord-ing to the Region selected.Data Rate (Mbps): This field allows you to specify the transmission rate. Select Auto to maximize performance.54g Mode: This field indicates the 802.11g interface mode. Selecting Auto allows both 802.11g and 802.11b clients to connect to the ASUS WL-HDD2.5. Selecting 54g Only maximizes performance, but prevents 802.11b clients from connecting to the device. If 54gProtection is checked, G-Mode protection of 802.11g traffic is enabled automatically in the presence of 802.11b traffic.Authentication Method: This field enables you to set different authentication methods for determining various encryption schemes. The relationship between Authentication Method, Encryption, Pass-phrase and WEP Keys is listed in the following table:Relationship among keys: Authentication Method Encryption Passphrase WEP Key 1~4Open System or Shared KeyNone Not required Not requiredWEP-64 bits 1~64 characters 10 hex digitsWEP-128 bits 1~64 characters 26 hex digitsShared Key WEP-64 bits 1~64 characters 10 hex digitsWEP-128 bits 1~64 characters 26 hex digitsWPA-PSK TKIP only 8~63 characters Not requiredAES only 8~63 characters Not required
48 ASUS 802.11g WL-HDD2.5Encryption: If the Open System or Shared Key or Shared Keyauthentication method is used, WEP (Wired Equivalent Privacy) encryption is applied. If the WPA-PSK method is used, a newly pro-posed TKIP or AES encryption in WPA is applied. Enabling WEP can protect your data from eavesdroppers. If you do not need this feature, select None to skip the following setting. The ASUS WL-HDD2.5 supports both 64-bit and 128-bit encryption using the WEP algorithm. Select the type of encryption you want to use (64 or 128 bit) and configure one to four WEP Keys. The 128-bitmethod is more secure than the 64-bit method.64/128 bits versus 40/104 bits: You may be confused about config-uring WEP encryption, especially when using multiple wireless LAN products from different vendors. There are two levels of WEP Encryption: 64 bits and 128 bits. 64-bit WEP and 40-bit WEP are the same encryption method and can inter-operate in the wireless net-work. This lower level of WEP encryption uses a 40 bit (10 hex digits [0~9, a~f, and A~F]) as a “secret key” (set by user), and a 24 bit “ini-tialization 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 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 inter-operate in the wireless network. This higher level of WEP encryption uses 104 bits (26 hex digits) 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 products use the term 128 bits when referring to this higher level of encryption.Passphrase: If you select TKIP only or AES only as the Encryption method, this field will be used as a password for the encryption pro-cess. A password with 8 to 63 characters is required. If you select WEP-64 bits or WEP-128 bits as the Encryption method, this field will be used to generate four WEP keys automatically. A WEP key is either 10 or 26 hexadecimal digits based on whether you select 64 bit
ASUS 802.11g WL-HDD2.5 49or 128 bit in the WEP pull-down menu. Type a combination of up to 64 letters, numbers, or symbols in this field, which will be used to generate the four WEP keys. If you want to type in the keys manually, leave this field blank. The Asus WLAN family of products uses the same algorithm to generate the keys so that all the products can use the same WEP key.WEP Key: At most four WEP keys can be set. A WEP key is either 10 or 26 hexadecimal digits (0~9, a~f, and A~F) based on whether you select 64 bit or 128 bit in the WEP pull-down menu. The ASUS WL-HDD2.5 and ALL of its wireless clients MUST have the same default key.Default Key: The Default Key field lets you specify which of the four encryption keys you use to transmit data on your wireless LAN. As long as the ASUS WL-HDD2.5 or a wireless mobile client with which you are communicating has the same key in the same position, you can use any of the keys as the default key. If the ASUS WL-HDD2.5 and ALL of its wireless clients use the same four WEP keys, select key rotation to maximize security. Otherwise, choose one key in common as the default key.Hide SSID : By default, No is selected so that wireless mobile users can see your ASUS WL-HDD2.5’s SSID and join the network. If Ye sis selected, your ASUS WL-HDD2.5 will not show in site surveys by wireless mobile clients and they will have to manually enter your device’s SSID. If you want to restrict access to your ASUS WL-HDD2.5, this is a simple way to do it.Basic Rate Set: This field indicates the basic rates that wireless cli-ents must support. Use 1 & 2 Mbps only when backward compatibil-ity is needed for some older wireless LAN cards with a maximum bit rate of 2 Mbps.Note: This function saves users from having to remember their passwords and is compatible for all ASUS WLAN products. How-ever, this is not as secure as the manual assignment of the keys.
50 ASUS 802.11g WL-HDD2.5WPA Re-key Timer: This field specifies the time interval after which the WPA group key is changed in seconds. 0 means no periodic key-change is required.Bridge
