Power down the Cable or DSL modem and the computer which will be used to congure the AirStation router. 2. Plug the Cable or DSL modems LAN Ethernet cable into the AirStations WAN port. You may need to unplug this cable from your computer, hub or other router. 3. Plug the provided Ethernet cable into a LAN port on the AirStation and plug the other end into your computer Ethernet adapters (NIC) port. If you plan to initially congure the AirStation via a wireless connection (not recommended), you may skip this step. 4. Power on your cable or DSL modem and wait one full minute. Power on the AirStation router, wait another full minute and then power on the computer which will be used to congure the AirStation. If the red DIAG light on the AirStation is lit or ashing after several minutes of being powered on, please consult Buffalo Technical Sup-

port. 11 Installation / Setup Introduction Conguring the AirStation using a standard web browser requires basic wireless conguration knowledge. Setup includes manual wireless conguration and basic administrative management. Setup Preparation Make note of the AirStations LAN MAC address (found on the underside of the WZR-HP-G54). It is also recommended that you record any other broadband ISP information, such as global IP ad-

dress, subnet mask address, default gateway address, DNS server address and PPPoE param-

eters. Setup Overview Buffalo recommends using a wired connection, meaning your computer is physically connected to the AirStation with a CAT5 cable plugged into one of the four LAN ports This type of setup will eliminate possible setup problems due to any issues with the wireless adapter on the computer be-

ing used to congure the AirStation. 12 Antenna Installation The WZR-HP-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. However, it may be necessary to increase your range further by installing an external, higher-gain antenna. Available ex-

ternal antennas are described as below. Antennas also come with different connectors. The WZR-HP-G54 has an unique MC Connector on it. Thus, the antenna must also have an MC connector. The following four antennas are allowed to connect to WZR-

HP-G54. WLE-DA: Patch Antenna WLE-NDR: Sleeve Antenna WLE-HG-NDR Sleeve Antenna WLE-MYG Yagi Antenna 13 Antenna Installation To install the antenna, slide the antenna connector door on the back of the WZR-HP-G54 to the right. This will expose the MC Connector. Attaching the antenna is simple; just in-

sert the antennas MC Connector into the WZR-HP-G54s MC Connector and rmly push it in until it snaps into place. Once clicked into place, the antennas connector should swivel easily. It is important not to push the antenna connector in at an angle. To remove the antenna, pull the antenna connector out. It is important not to pull the antenna connector out at an angle. 14 Standard Settings Initial Settings Login Open the Setup Screen The computer used to con gure the Airstation should be set to obtain an IP address automatically The computer used to con gure the Airstation should be set to obtain an IP address automatically using a DHCP server.

Click the Top tab and click the Advanced button to enter the Advanced settings area. 22 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 SSID's. The intelligence of AOSS determines the most optimal connection and congures itself in seconds. NOTE: AOSS automatically creates a secure connection between your AOSS Access Point and client. You must have a Buffalo AOSS enabled wireless client device to use the AOSS features of your AOSS Access Point/Router. Congure your WZR-HP-G54s internet connection by referring to the instructions in the WZR-HP-G54 Quick Setup Guide. Once the WZR-HP-G54 has been cong-

ured, follow the directions to install your wireless client device and its drivers if necessary. Certain wireless client adapt-

ers require client software to congure them. If your device has a Client Man-

ager, install it as well. Standalone AOSS Device Client Manager Device Client Manager Software NOTE: If the wireless client adapter is installed on a PC, then the AOSS client manager will need to be installed as well. If your wireless client adapter is a standalone device that does not require a PC, then just power up the device. Standalone Devices: Ethernet Converters and Access Point Bridges Client Manager Devices: CardBus, USB, and PCI Adapters. 23 AOSS Now that the WZR-HP-G54 and wireless client adapter are installed, you can use AOSS to con gure them. To begin the con guration, press the AOSS button on the side of the WZR-HP-G54 for 3-5 seconds. The AOSS light will begin to ash when the AOSS mode has been enabled. You can stop pressing the button at this point. NOTE: AOSS mode will stay active for a period of two minutes. This is the time-slot for initiating the wireless client adapter. The AOSS LED will stop ashing when AOSS mode has stopped or timed out. Refer to your wireless client adapter's AOSS supplement to initiate the wireless client adapter's AOSS mode. It typically takes 10-15 seconds for the AOSS light to stop ashing after the AOSS button has been pressed on the wireless client adapter. Once con guration is complete, the AOSS light will remain steady. Please refer to your wireless client adapter's supplement for the remainder of the setup. 24 AOSS Additional AOSS Information:

Only one AOSS wireless client adapter can be congured 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 congured via AOSS unless signicant changes have been made to the wireless network. Do not attempt to congure two separate AOSS networks at the same time, as it may cause undesired congurations. If an undesired client has connected via AOSS, it can be disconnected from within the WZR-HP-

G54s advanced conguration menus. 25 Advanced Settings Wireless Settings LAN Settings Wireless Settings Wireless Function - Enable or disable wireless LAN computer communication. SSID - Allows administrator to alter the SSID of the AirSta-

tion. Once this is done, the APs new SSID should be se-

lected in the client computers wireless settings. The client computer then looks for that speci c AP (and SSID) for wire-

less communication. Use up to 32 al pha nu mer ic characters for the SSID (case sensitive). By default the SSID is the LAN Mac address of the AirStation. Note: Roaming - When multiple AirStations have an identical SSID, WEP key (if WEP is used),

(and channel in WDS mode) , client computers may Roam seamlessly between the AirStations. Wireless Channel - Select the channel used for wireless communication. There are 11 overlap-

26 Advanced Settings ping channels. Channels 1, 6 and 11 are non-overlapping. The Auto-Channel option is recommended, as it constantly assesses the best available channel for the AirStation to operate on. 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. Note: If this function is used, wired clients can still communicate with wireless clients. BSS (Basic Service Set) Basic Rate Set - The transmission data rates offered by the AirStation. It is recommended to use the Default selection to accomidate 802.11 and 802.11b rate sets. It is NOT recom-

mended to use the All selection, as some devices may not understand all of the rate sets offered by the AirStation. Frame Bursting - This function increases 802.11g communication throughput by transferring packets more efciently. The following conditions affect this function:

The wireless LAN client adapter must support Frame Bursting (and it must be enabled). If the wireless LAN client adapter does not support Frame Bursting, or Frame Bursting is not enabled, then it will operate at non-Frame Bursting speeds. 125* High-Speed Mode - This function increases the routers speed beyond that of normal 802.11g com-

munication. Rate sets up to 125* Mbps are offered to clients. Note:

The wireless LAN client adapter must support 125* High-Speed Mode, and have it enabled, for the network to operate in 125* High-Speed Mode. If the wireless LAN client adapter does not support 125* High-Speed Mode, or it is not enabled, then the wireless network will operate at regular 802.11g 27 Advanced Settings speeds. You may leave 125* High-Speed Mode enabled at all times. It can only help throughput, not hurt it. 802.11g Protection - This enables protection mechanisms for when 802.11b clients join the net-

work. It enables CTS (Clear-to-Send). DTIM Period - An access point transmits beacon signals to nearby clients at a preset interval. This parameter sets the beacon transmission interval time (1-255 seconds). Se lec tion of a larger num-

ber may conserve energy for the client computer (when client power management is enabled), but may delay wireless communication. The default value of 1 is recommended. Wireless Wireless Security Security Settings Settings Wireless Output Power - Con g-

ure 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 - You may Enable or Disable broadcasting the SSID. If denied, the AirStation will not be 28 Advanced Settings found unless the specic AirStations SSID is entered in the client computer manually. Data Encryption - Disable to have no encryption of the wireless data. This will make accessing the AirStation and the network very easy. It is important to note that without encryption, its easy for strangers to connect to your network, especially if your AirStation is broadcasting its SSID. Select the type of data encryption:

Disabled - Disable data encryption.

- WEP - Uses WEP encryption. Encryption 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 encrypt, transmit, and decrypt data. For this reason, the same WEP key must be used for communication between the client and the AirStation. An access point and client may both carry multiple WEP keys. It is necessary for not only the WEP keys to match, but also the WEP keys order. If a wireless client cannot support multiple WEP keys, the AirStations must be congured to transmit key number 1 for a connection to take place. Examples of WEP key:

64-bit ASCII: 5 digits of alphanumeric characters, ab34Y 128-bit ASCII: 13 digits of alphanumeric characters, 123456abcdef7 29 Advanced Settings Note: ASCII WEP keys are case sensitive. 64-bit HEX: 10 digits, using characters 0-9 and a-f, 00234ABCDE 128-bit HEX: 26 digits, using characters 0-9 and a-f, 20123456789abcdeabcdeabcde TKIP - TKIP (Temporal Key Integrity Protocol) is a WEP expanded encryption technique. TKIP has greatly improved WEPs weaknesses by rotating secret keys between every packet. TKIP uses WPA-PSK (pre-Shared Key). 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. AES - AES further improves TKIP by using AES (Advanced Encryption Standard) encryption meth-

od. With its hardware co-processor, AES is able to use some of the strongest encryption available without sacricing throughput as WEP and TKIP do. TKIP & AES require an 8 to 63 character passphrase in ASCII or a 64 digit 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 inter-

val. This interval is in seconds; the range of acceptable values is 0-3600. If 0 is entered, the key is never renewed. 30 Advanced Settings IEEE802.1x/EAP authentication (WPA) - Congure Authentication and WPA Settings. Disable - Do not use any RADIUS Server based authentication. Enable - Authorized clients access this AirStation via a RADIUS Server. Use 802.1x/EAP to authorize every wireless client who wants to access the AirStation by using 802.1x/EAP and a RADIUS Server. The RADIUS server provides login information for every user establishing a more secure system than TKIP or other xed encryption key methods. This also reduces the amount of necessary key maintenance. A RADIUS server is necessary for IEEE802.1x/EAP authentication. Enter [RADIUS Server], {RA-

DIUS Port] and [RADIUS Key] information. RADIUS authentication:

RADIUS Server - Enter RADIUS server IP address. RADIUS Port - Enter port number for authentication. RADIUS Key - Encryption key between RADIUS Sever and the AirStation. Enter the same key as registered in the server. Use a 1 to 256 character alphanumeric code. 31 LAN Port LAN Port Settings Settings Advanced Settings Note: The lower the rekey interval, the more often a rekey occurs. Setting a low rekey in-

terval may affect performance negatively. LAN Port Set the LAN side Ethernet settings. LAN Side IP Address - Allows ad min is tra tor to specify a static IP and Subnet Mask for the LAN side of the AirStation. Note: If the AirStations IP address is changed, the con guring computers IP must be changed to the same range to continue con guration. If the LAN IP is changed, restart the AirStation. (Section 4.4.10). If the IP address is changed, then the DHCP scope must be changed to match. DHCP Server Function - Allows administrator to enable/disable the DHCP server function for the AirStation LAN side. Select Use to enable and Do not use to disable the function. Once Use is selected, the assigned IP address range can be speci ed. Enter the starting LAN IP address and total number of computers the DHCP server can accomidate. Note: If there is another DHCP server on the network, one either must be disabled or the IP 32 DHCP Server DHCP Server Settings Settings Advanced Settings range must be changed to avoid con icts derived from overlapping DHCP scopes.

B. 1.3 Other Problems Please refer to www.buffalotech.com for further reference materials. 78 Troubleshooting 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 conguration web page. For proper setup, please continue reading this document. Problem:

Communication problems with WDS (wireless bridging/repeating). Cause:

WDS is a very complex bridging system, and is not part of the 802.11b or 802.11g standards. Restrictions:

Please verify that the following conditions are met (if just one condition is not satised, then WDS can-

not be used on the wireless network):

1. All wireless access points in the wireless bridge need to be from the same vendor (e.g. all Buffalo access points).

(At time of publication, the Apple Airport Extreme WILL work in WDS with Buffalo G54 access points.) 2. No single access point can communicate with more then six other access points in the wireless bridge. 79 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. It is recommended that all access points in the bridge are reset to their factory default settings. This is done by holding the INIT button on the rear of the access point down for 5-10 seconds. 2. Login to the rst access point in the wireless bridge (this should be the DHCP server enabled ac-

cess point if there is not already a routed wired network). 3. Click on the Advanced button. 4. The wireless settings page will appear. Select the proper settings for the wireless network. Record all settings on a piece of paper. All settings except for the SSID need to be identical amongst all access points in the bridge. If roaming is desired, then make sure the SSID settings are identical as well. Press the Apply button after any changes are made. If the IP address was changed, then reconnecting to the access point for conguration will require accessing it via its new IP address in a web browser (e.g. http://NEW_IP_ADDRESS). 5. Click on the LAN port link on the left. 80 Troubleshooting 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 Apply button if any settings on this page have been changed. 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 colons (i.e. 00:00:0A:1B:2C:DF). Please make sure the MAC address is recorded from the Wireless section and not the other sections. 9. Logout of the access point by clicking on the Logout link on the left. Close the browser window. 10. Login to the second access point in the wireless bridge. 11. Click on the Advanced button. 12. The wireless settings page will appear. Select the proper settings for the wireless network. Refer to the settings recorded from the rst access point. All settings except for the SSID need to be identical for all access points in the bridge. If roaming is desired, then make sure the SSID settings are identi-

cal as well. 13. Click on the LAN port link on the left. 14. Make sure that the IP address for the LAN side IP address setting is different from that of the rst access point. The IP addresses cannot be the same, but they should be on the same network. It is recommended that the IP address of the second access point is one higher then that of the rst ac-

cess point. Thus, if access point ones address is 1.1.1.1, then access point twos address should be 1.1.1.2. If there is a DHCP server function setting on this page, then make sure to set it to Disabled. Press the Apply button when nished. 81 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 rst access point (which was recorded on Step 8) into the eld 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. Please check that the checkbox under enable is checked, and then press the Enable marked item button. 19. At the top of the page, press the Apply button. 20. Once the router has rebooted, click on the Management tab on the left. 21. The System Information page will appear. In the Wireless section of the table record the MAC ad-

dress (including the :s). Please make sure the MAC address is recorded from the Wireless section and not the other sections. 22. Logout of the access point by clicking on the Logout link on the left. Close the browser window. 23. Login to access point one again. 24. Click on the Advanced button. 25. Click on the Wireless bridge (WDS) link on the left. 26. Enable the WDS function and press the Apply button. 27. Enter the Wireless MAC Address of the rst access point (which was recorded on Step 21) into the eld that say MAC Address of AirStation(Wireless) (include the :s). Press the Add button. 82 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 eld 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. If the Result section of the table reports Destination Host Unreachable, then an error has oc-

curred during the setup. WDS is a complicated bridging system with a lot of variables. If there are still problems with WDS con-

guration on the network, then please call our 24/7 technical support line at 1-866-752-6210. 83 Glossary 10BaseT or 100BaseTx: 802.3 based Ether-
