10 About the AirStation CD The AirStation does not require any software to be installed on your computer for confi guration. The AirStation CD contains client drivers for Buffalo Wireless Adapters (i.e. Notebook Adapter and Desktop PCI Adapter) and the AirStation documentation.
11 Follow these simple steps to connect the AirStation to your Broadband Internet connection allowing 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 confi gure the AirStation router .
12 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 underside of the WHR3-G54).
13 The WHR3-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 Advanced settings for security , fi ltering and other features will be explained in later sections. Open the Setup Screen • Connect the WHR3-G54 according to the wiring instructions in Section 2. • The WHR3-G54 has a default LAN IP address of 192.
15 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.
16 Enter IP Address Manually - Enter the IP Address given by the ISP . - Use ‘Enter IP Address Manually’ if the ISP requires use of a static IP address.
17 CA TV (Cable) Button Select the appropriate connection method. Automatic IP Assignment by ISP - Select ‘Automatic IP Assignment by ISP’ if your ISP’s DHCP server assigns an IP address automatically . Enter IP Address Manually - Select ‘Enter IP Address Manually’ if the ISP requires use of a static IP address.
18 The IP Address is Acquired Au to mat i cal ly but DNS Server Address is Entered Manually - Select ‘IP address is acquired automatically but DNS server address is entered manually’ if the ISP’s DHCP server supplies an IP address but not DNS server addresses.
19 Security The Security T ab of fers three Simple Security Settings. Follow the in struc tions in each screen to enter Encryption Keys, MAC Address Filter- ing and the degree of fi rewall security for the AirStation.
20 Encryption Setup. - Select the desired encryption scheme from the choices. After it has been selected, press the ‘Next’ button. Y ou will then be prompted to enter the appropriate key(s) for that method of encryp- tion. Simple MAC Address Filter .
21 Applications The Application T ab offers setup for special ap- plications such as games, MS NetMeeting and MSN Messenger . Then follow the on-screen menus to confi gure the AirStation for the applica- tion.
22 Internet Gaming Setup -Enter the ports (refer to Game documentation) the game runs on, and enter the Local IP Ad- dress of the PC that plays the game. NetMeeting Setup -Enter the IP Address of the PC that will use Netmeeting. MSN Messenger Setup -Refer to the on-screen help for information about Messenger .
23 AOSS AOSS (AirStation One-T ouch 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 SSID's.
24 ◗ Now that the WHR3-G54 and wireless client adapter are installed, you can use AOSS to confi gure them. ◗ T o begin the confi guration, press the AOSS button on the side of the WHR3-G54 for 3-5 seconds. The AOSS light will begin to fl ash when the AOSS mode has been enabled.
25 Additional AOSS Information: ◗ Only one AOSS wireless client adapter can be confi gured 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.
26 LAN Settings Set up LAN connections. Wireless Settings Wireless Function - Enable or disable wireless LAN computer communication. SSID - Allows administrator to alter the SSID of the AirStation. T o communicate with a specifi c AP only , the AP’s SSID must be entered in the client comput- er .

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 confi guration 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 fi rst access point (which was recorded on Step 8) into the fi eld 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’ fi eld 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 specifi c 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 identifi es 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 .
