Introduction neously. Buffalo AirStation wireless access points enable sharing broadband by simply connecting the AirStation to a DSL or CATV modem to: • Share files and printers • Access and share the Internet • Share media files SOHO/SMB Networking With high-speed DSL or CATV connections readily available, many users can work effectively from a home office, connected securely to a corporate network.
Introduction The LAN or Wired MAC address is the default ESS-ID (SSID) of the AirStation. The LAN MAC address is clearly labeled on the back of the AirStation. office.
Introduction ing Local area connection • Any Wi-Fi (wireless) compatible computer with a Web Browser Internet Explorer or Netscape 4.5 or later. (Safari 1.0 is supported with Macintosh OS X.2) AirStation WBR2-G54 Package Contents The AirStation WBR2-G54 package consists of the following items. 1. WBR2-G54 Base Station 2. AC adapter and power cable 3. CAT5 LAN cable 4. Utility CD with Manual 5. Quick Setup Guides 6. Warranty Statement Product Views Power - Lit when the device is powered on.
Installation / Setup About the AirStation CD The AirStation does not require any software to be installed on your computer for configuration. The AirStation CD contains client drivers for Buffalo Wireless Adapters (i.e. Notebook Adapter and Desktop PCI Adapter) and the AirStation documentation. Prior to copying or installing any software, please read the Software License Agreement “license.txt”, located in the root folder of the CD.
Installation / Setup you to combine and share wired and wireless computers and printers with the high-speed internet connection. 1. Power down the cable or DSL modem and the computer which will be used to configure the AirStation router. 2. Plug the cable or DSL’s LAN Ethernet cable into the AirStation’s WAN port. Initially, you may need to unplug this cable from your computer, hub or other router. 3.
Antenna Installation The WBR2-G54 has two internal antennas. One has a vertical orientation while the other has a horizontal orientation. This setup is ideal because it allows for proper antenna polarization with both desktop and notebook style wireless adapter antennas. However, it may be necessary to increase your range further by installing an external, higher-gain antenna. External antennas come in all shapes and sizes. Antennas also come with different connectors.
Standard Settings Introduction Configuring the AirStation using a standard web browser requires basic wireless configuration knowledge. Setup includes manual wireless configuration and basic administrative management. Setup Preparation Initial Settings Login Make note of the AirStation’s wired MAC address (found on the back of the WBR2G54).

AOSS AOSS (AirStation One-Touch Secure System) is a simple, one-touch setup for connecting wireless clients to an access point while setting up the most secure possible connection. Users no longer need to worry about choosing the proper security protocols, IP addresses, or ESS-ID's. The intelligence of AOSS determines the most optimal connection and configures itself in seconds. n NOTE: AOSS automatically creates a secure connection between your AOSS Access Point and client.
AOSS ◗ Now that the WBR2-G54 and wireless client adapter are installed, you can use AOSS to configure them. ◗ To begin the configuration, press the AOSS button on the back of the WBR2-G54 for 3-5 seconds. The AOSS light will begin to flash when the AOSS mode has been enabled. You can stop pressing the button at this point. n NOTE: AOSS mode will stay active for a period of two minutes. This is the time-slot required to initiate the wireless client adapter.
AOSS Additional AOSS Information: ◗ Only one AOSS wireless client adapter can be configured to the AOSS router at a time. Thus, the button will need to be repressed for each additional AOSS wireless client adapter that will be connected. ◗ It is not necessary to AOSS client devices that have already been configured via AOSS, unless significant changes have been made to the wireless network.
Advanced Settings LAN Settings Set up LAN connections. Wireless Settings Wireless Settings Wireless Function - Enable or disable wireless LAN computer communication. ESS-ID (SSID) - Allows administrator to alter the ESS-ID of the AirStation. To communicate with a specific AP only, the AP’s ESS-ID must be entered in the client computer. The client computer looks for the specific AP (or ESS-ID) for wireless communication. Use up to 32 alphanumeric characters for the ESS-ID (case sensitive).
Advanced Settings ping 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. Privacy Separator - Enable or disable communication between wireless clients. If you choose to use this feature, every wireless client that is associated to the AirStation will not be able to communicate with any other wireless clients.
Advanced Settings may delay wireless communication. The default value of 1 is recommended. Wireless output power - Configure output power of the AirStation. Decrease wireless output power to shrink the wireless communication range. The default setting of 100% is recommended unless decreased range is desired Wireless LAN Security Broadcast SSID - Enable or Disable the SSID (ESS-ID) from being broadcasted.
Advanced Settings cryption key should be entered. - TKIP - Uses TKIP (Temporal Key Integrity Protocol) for data encryption. The encryption key is renewed every “Re-key interval” when “TKIP” is selected. WEP - When the WEP (Wired Equivalent Protection) encryption standard is implemented into a wireless network, a WEP key is used between the client and access point to successfully encrypt, transmit and decrypt data.
Advanced Settings Characteristics: - The Initialization Vector is expanded from 24-bits to 48-bits. - The Initialization Vector is randomized. - Uses a different RC4 key for every packet. TIKIP requires an 8 to 63 character passphrase in ASCII or 64 digits hexadecimal key. Example 1: [ airstation -WPA-PSK ] Example 2: [0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef] WPA Group Rekey Interval - When TKIP is selected, the encryption key is renewed at this interval.

Troubleshooting Troubleshooting WDS (Step-by-Step Instructions) The most common issue with WDS installations is using the wrong MAC address. The proper MAC Address for the access points is the ‘Wireless MAC Address’. The best place to document this is under the ‘System Information’ section of the configuration web page. For proper setup, please continue reading this document. Problem: Communication problems with WDS (wireless bridging/repeating).
Troubleshooting The following is a list of good practices with WDS: 1. Start the wireless bridge system with only two access points and then add more access points. 2. Setup all access points in the wireless bridge in close proximity before they are deployed to their proper location. 3. Only one access point in the wireless bridge should be serving DHCP and routing services unless a routed wired network exists. Proper Setup: Please follow the following steps to properly setup WDS. 1.
Troubleshooting 5. Click on the ‘LAN port’ link on the left. 6. Check that the ‘LAN side IP address’ values are correct for your network, or leave them as default. Record the ‘LAN side IP address’. Press the ‘Set’ button if any settings on this page have been set. 7. Click on the ‘Management’ link on the left. 8. The System Information page will appear. In the Wireless section of the table record the MAC address (including the :’s).
Troubleshooting 15. Click on the ‘Wireless bridge (WDS)’ link on the left. 16. Enable the WDS function and press the ‘Set’ button. 17. Enter the Wireless MAC Address of the first access point (which was recorded on Step 8) into the field that say ‘MAC Address of AirStation(Wireless)’ (include the :’s). Press the ‘Add’ button. 18. The Wireless MAC address inputted on the step above will appear in the ‘Connected AirStation’ table.
Troubleshooting 29. At the top of the page, press the ‘Apply’ button. 30. Once the router has rebooted, click on the ‘Management’ tab on the left. 31. Click on the ‘PING test’ link on the left. 32. In the ‘Destination’ field enter the IP address of the second access point and press the ‘OK’ button. a. If the ‘Result’ section of the table reports information like, “1st: 64 bytes from IP_ADDRESS” then the WDS bridge is effectively working. b.
