To place a shortcut icon on the desktop, click Yes. Otherwise, click No. 3 STANDARD SETTINGS 3.1 Introduction Setting up the AirStation parameters using a Web Browser requires basic wireless configuration knowledge. For Advanced settings and explanations of each parameter and its use, see Chapter 4. 3.2 Setup Overview The WLA2-G54 is configured to function right out of the box. Simple settings for security and MAC Address registration are offered in this sectionSpecialized setups for security, filtering and other features will be explained in later sections by clicking the Advanced Button. 3.3 Open the Setup Screen · Click WEP to enter simple WEP setting to protect your wireless data. Select WEP to input a password or encryption code to protect wireless communications. It is possible to enter up to 4 different WEPs. The WEP key must match between two parties for secure communications. Examples of WEP key: 64bit ASCII: 5 digits of alphanumeric characters, "ab34Y" 128bit ASCII: 13 digits of alphanumeric characters, "123456abcdef7" Note: ASCII WEP is case sensitive. 64bit HEX: 10 digits, using characters 0-9 and a-f, "00234ABCDE" 128bit HEX: 26 digits, using characters 0-9 and a-f, "20123456789abcdeabcdeabcde" Register for allowable PC's MAC address - MAC access restriction set up in LAN. Input the MAC addresses that is to be allowed to communicate. MAC address list - Display a table list of all MAC addresses. 4 USING AIRSTATION FOR ADVANCED CONFIGURATIONS Although your AirStation will function fine using only the settings from Section 3, you may wish to explore more advanced options. This chapter explains each parameter in the Advanced button. Click the Top tab and click the Advanced button. 4.1 LAN Setting 4.1.1 Wireless Wireless function - Enable or disable wireless communication Wireless Mode - Select one of the following: 11g(54M)/11b(11M)-Auto - Allows communication of 11g and 11b devices. Communication speed will drop to 11Mbps when 11b devices are connected. 11g(54M)-Turbo - Boosts 11g devices to turbo 54Mbps mode. 11g(54M)-Only - 11g devices will be able to communicate, but not 11b devices. ESS-ID - Allows administrator to alter the ESS-ID of the AirStation. Default ESS-ID is the LAN MAC Address.To communicate with a specific AP only, the AP's ESS-ID must be entered in the client PC. The client PC looks for the specific AP (or ESS-ID) for wireless communication. Use up to 32 alphanumeric characters for the ESS-ID (case sensitive). Note: Roaming - When multiple AirStations have an identical ESS-ID, WEP, and DS channel, client PCs may Roam between the AirStations. Wireless Channel - Select the channel used for wireless communication. There are 11 overlapping channels. Channels 1, 6 and 11 are non-overlapping. If there are multiple APs in close proximity using the same channel, there may be interference. In this case, change to a non-overlapping channel. Note: This parameter is automatically set in the client computer. WPA Configuration - Configure WPA(Wi-Fi Protected Access) setting. Do not use the WPA function if the WEP encryption is selected from "Type of encryption" field. 802.1X Use 802.1x authorization. Clients authorized by RADIUS servers can access this AirStation. RADIUS Server, RADIUS Port and RADIUS Key should be entered.You can also use secure communication selecting WEP encryption from "Type of encryption" field. WPA Authorized client by RADIUS server can access this AirStation. RADIUS Server, RADIUS Port and RADIUS Key should be entered.You should select either TKIP (Temporal Key Integrity Protocol) or AES (Advanced Encryption Standard) from "Type of encryption" field. WPA-PSK Clients access this AirStation by PSK (Pre-Shared Key) without RADIUS authorization. You should select either TKIP (Temporal Key Integrity Protocol) or AES (Advanced Encryption Standard) from "Type of encryption" field. Examples of WPA key: WPA-PSK (Pre-Shared Key) must be composed of at least 8 characters, but no more then 63 characters. The following are acceptable characters for a WPA-PSK key: Upper case letters, lower case letters, numbers, spaces, punctuation <>?=+&% WPA-PSK Key Example: "This is <1> example of a WPA Key" Note: WPA keys are case sensitive. Type of Encryption - Select Off, WEP, TKIP or AES If WEP is selected, create and enter an encryption code to protect wireless communications. It is possible to enter up to 4 different WEPs. The WEP key must match between two parties for secure communications. 5 Examples of WEP key: 64bit ASCII: 5 digits of alphanumeric characters, "ab34Y" 128bit ASCII: 13 digits of alphanumeric characters, "123456abcdef7" Note: ASCII WEP is case sensitive. 64bit HEX: 10 digits, using characters 0-9 and a-f, "00234ABCDE" 128bit HEX: 26 digits, using characters 0-9 and a-f, "20123456789abcdeabcdeabcde" Privacy Seperator - Select Use or do not use to block communication between each wireless LAN PC on the wireless network. If you choose to use, every wireless LAN PCs that is associated to the same AirStation can not communicate with each other. Even if this function is used, wired LAN PCs can communicate with wireless LAN PCs. BSBasic Service Set) Basic Rate Set - The transmission data rate between devices. If one device supports 2Mbps only, the data rate for the entire network should be limited to 2Mbps ("Default" selection). Otherwise, use 11Mbps max ("All" selection). Frame Bursting - Increase IEEE802.11g communication throughput by transferring packets continuously. However, the following condition effects this function. The client wireless LAN adapter must support Frame Bursting feature too.When multiple wireless clients use Frame Bursting feature, the throughput might not increase Holding 802.11b Association - When this function is enabled, the AirStation requests IEEE802.11b devices to stop communication for a while prior to starting IEEE802.11g communication. If communication speed is decreased, this setting improves total throughput with existing IEEE802.11g and IEEE802.11b standard devices,. The throughput decreases if only IEEE802.11g standard devices exists. DTIM Period - An transmits beacon signals to nearby clients at a preset interval. This parameter sets the beacon transmission interval time (1-255 sec.). Selection of a larger number may conserve energy for the client PC (when client power management is enabled), but may delay wireless communication. The default value of 1 is recommended. ANY Connection - The AirStation can be configured to accept connections from any wireless client using an ESS-ID of "ANY". Roaming wireless clients will automatically connect to the nearest access point accepting ANY connections. The only options are to allow or deny connections for these types of clients, thus, wireless networks requiring security should mandate a WEP encryption policy to preserve security if ANY connections are allowed. If Deny is selected under the the "ANY Connection," SSID of the AirStation will not be broadcast and users will not be able to connect to the WLA2-G54 unless the specific ESS-ID is entered in the client PC. Wireless Output Power - Adjust the power ouput power of the radio. 4.1.2 LAN port Set LAN interface parameters. LAN Side IP address - Allows administrator to select whether AirStation is assigned an IP address by a DHCP server or specify a static IP and Subnet Mask for the LAN side of the AirStation. Note: If the AP's IP address is changed to a different range, the setting PC's IP must be changed to the same range to continue configuration. Then restart the setup session from the AirStation utility screen. Default Gateway - Allows administrator to use the Default Gateway address (the AirStation's IP address), assign a specific Gateway address, or block clients from Gateway notification. DNS server - Allows administrator to use the default DNS address (the AirStation's IP address), assign specific DNS addresses, or block clients from DNS address notification. 6 4.1.4 Wireless LAN C ...
