DHCP server.
ASUS WL-127 Card
Config - Basic Tab
The Basic tab provides general information on network types and other configurations.
Network Type. Select which type of network you wish to use. Select Infrastructure mode to establish a connection with an Access Point (AP).
In this mode, your system can access wireless
LAN and wired LAN (Ethernet) via the AP. Select the Ad Hoc mode to communicate directly with other Wi-Fi devices within the WL-127 operating range.
Network Name - Displays the network SSID. The network SSID is a string use to identify a wireless
LAN. Assign different SSIDs to segment the wireless LAN and increase network security. Set the SSID to a null string to allow your station to connect to any available Access Point. Null string may not be used in Ad Hoc mode.
Channel. In Infrastructure mode, WL-127 automatically selects the correct frequency channel. In Ad Hoc mode, select a channel that is allowed for use in your country/region. See page 27 for channel information.
ASUS WL-127 Card 17

Data Rate. Select Fully Auto to allow WiFi-b to adjust to the most suitable connection. You may also fix data transfer rates to 11, 5.5, 2 and 1 Mbps.
PS Mode. This field allows control of the WL-127 card power saving features. The CAM
(Constantly Awake mode) is recommended for systems running on AC power.
Others. Click the WEP or Advanced link to open the Encryption or Advanced property tab sheet.
Config - EncryptionTab
Wireless data transmissions between your WL-
127 and the AP are secured using the Wired
Equivalent Privacy (WEP) encryption. Check the
Data encryption (WEP enabled) option to assign the WEP keys.
Check the Network Authentication (Shared Mode) option if you wish to use a network key to authenticate a preferred wireless network.
Unchecking this option allows the network to operate on an Open System mode.
ASUS WL-127 Card
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-bit encryption contains
10 hexadecimal digits or 5 ASCII characters. A 128-bit encryption contains 26 hexadecimal digits or 13 ASCII characters.
NOTE. 64-bit and 40-bit WEP keys use the same encryption method and can interoperate on wireless networks. This lower level of WEP encryption uses a 40-bit
(10 hexadecimal digits assigned by the user) secret key and a 24-bit Initialization
Vector assign by the WL-127. 104-bit and 128-bit WEPs uses the same encryption method.
Two ways to assign WEP keys
Manual Assignment. For a 64-bit encryption, enter 10 hexadecimal digits (0~9, a~f, A~F) in each of the four WEP keys.
Automatic Generation. Type a combination of up to 64 letters, numbers, or symbols in the
Passphrase field. The Wireless Settings Utility uses an algorithm to generate four WEP keys based on the typed combination.
ASUS WL-127 Card 19
NOTE. After assigning the WEP keys, Click APPLY to save and activate the encryption. Manually assigned encryptions are more secured than automatically generated encryptions.
Config - Advanced
The Advanced tab displays the WL-127 card advance settings. It is recommended that you do not make any changes on these settings.
