10 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 1 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.
12 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 W AN port.
13 The WBR2-G54 has two internal antennas. One has a vertical orientation while the other has a horizontal orienta- tion. This setup is ideal because it allows for proper antenna polarization with both desktop and notebook style wireless adapter antennas.
14 Introduction Confi guring the AirStation using a standard web browser requires basic wireless confi guration knowledge. Setup includes manual wireless confi guration and basic administrative management. Setup Preparation Make note of the AirStation’s wired MAC address (found on the back of the WBR2- G54).
15 A Web browser version 4.5 or later can be used to configure the AirStation. Advanced settings for security , filtering and other features will be explained in later sections. Open the Setup Screen • Connect the WBR2-G54 according to the wiring instructions in Section 2.
16 Enter ISP information • Click the appropriate button to select the type of broadband access. (Users more experienced in networking may choose to select the Ad- vanced button and skip to Section 4.) • For supplementary tools, use the tabs along the top of the screen.

79 Troubleshooting WDS (Step-by-Step Instructions) The most common issue with WDS installations is using the wrong MAC address. The proper MAC Ad- dress 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.
80 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.
81 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.
82 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).
83 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.
84 10BaseT or 100BaseTx: 802.3 based Ether- net network that uses UTP (Unshielded twisted pair) cable and a star topology . 10 is 10 Mbps and 100 is 100 Mbps. 802.1x: The standard for wireless LAN authenti- cation used between an AP and a client. 802.
85 Driver: Software that interfaces a computer with a specific hardware device. DSSS (Direct Sequence Spread Spectrum): Method of spreading a wireless signal into wide frequency bandwidth. DTE (Data T erminal Equipment): Device that con10BaseT or 100BaseTx: 802.
86 IP (Internet Protocol) Address: A unique 32- binary-digit number that identifies each sender or receiver of information sent in packets. Infrastructure: A wireless network or other small network in which the wireless network devices are made a part of the network through the Access Point.
87 mation between computers. RADIUS (Remote Authentication Dial In User Service): A server that issues authentication key to clients. RAM (Random Access Memory): Non-permanent memory .
88 Script: A macro or batch file containing instruc- tions and used by a computer to perform a task. Server: Any computer that makes files or peripheral devices available to users of the network and has a resident Network OS.
89 W AN (Wide Area Network): A networking sys- tem covering a wide geographical area. WEP (W ired Equivalent Privacy): An encryp- tion method based on 64 or 128-bit algorithm.
