Firmware Update Click Browse to select your firmware update file. Then, click the Firmware Update button to update firmware. Firmware Update may take several minutes to complete. Do not power down the router until Firmware Update is finished and the diag light on the front of the router has stopped blinking. When available, updated firmware may be downloaded from www.buffalotech.com.
System Information The System Information page lists all the setup information for your AirStation. It can be very handy for setting up clients that don’t support AOSS.
Log Information Here you can choose what information gets logged and see recent log entries.
Packet Traffic Information Here, you can see the packets and errors for each of your networks.
Client Monitor Client Monitor shows you a list of all clients currently connected to the wireless network.
Ping Test To perform a Ping test, enter a target (such as 192.168.11.2 or www. buffalotech.com) and click Execute. Successful pings return “64 bytes from . . .” messages. If the ping returns “Connection failed” or other errors, something is preventing you from communicating successfully with your target.
Connecting to a Preexisting Network Add an AirStation without changing your existing LAN configuration 1. Set the AirStation into Access Point Mode by moving the switch on the bottom from AUTO to BRI. 2. Connect one of the AirStation’s LAN ports to an existing router or switch on your network. Nothing should be plugged into the WAN port. 3. Open LAN Settings - LAN Port Settings and configure the following settings: IP Address =[192.168.11.1] (Specify an unused network address from the existing LAN.
Antenna The WHR-HP-G54’s external antenna will usually give the best performance if oriented to point straight up. If your AirStation is resting on its side, use the antenna’s swivel and twist function to orient it pointed upward. In some environments it’s desirable to further increase range by installing an external, higher-gain antenna. External antennas come in all shapes and sizes. Antennas also come with different connectors. The WHR-HP-G54 has an RP-SMA connector on it.

Specifications Note: The range values listed in Table “Radio Characteristics” are typical distances as measured at Buffalo Technology AirStation laboratories. These values are provided for your guidance but may vary according to the actual radio conditions at the location where the AirStation product is installed. AirStation IEEE 802.11 Channel Sets The range of the wireless signal is related to the Transmit Rate of the wireless communication.
Troubleshooting Common Problems • • • • Out of range, client cannot connect to the AirStation. Configuration mismatch, client cannot connect to the AirStation. Absence or conflict with the Client Driver. Conflict of another device with the AirStation hardware. LED Activity Monitoring LED activity helps identify problems. • Power LED should be Green, • Wireless LED should be Green if the line is active. If is it blinking Green, wireless communication is active.
Troubleshooting DIAG LED Activity Table DIAG LED Display Time Description/Action Continuous Red Starting RAM Error Red flash, 2 times Starting Flash ROM Error Red flash, 3 times Starting A problem on the wired LAN side Red flash, 4 times Starting A problem on the wireless LAN side LEDs Work But Client PC Cannot Connect to Network If the LEDs indicate that the network is working properly (Power LED is on, Transmit/ Receive LED blinks), check the TCP/IP settings of the network.
Troubleshooting • If the wireless adapter protocol is not yet installed, click the Add button and select the TCP/IP protocol from the list. Refer to Windows Help for more information. • If the wireless adapter protocol is installed, select the protocol and click the Properties button. Verify that the parameters match the settings provided by your LAN Administrator. Make changes if necessary, and click OK. 5. If prompted, restart your computer. Other Problems Please refer to www.buffalotech.
Troubleshooting Troubleshooting WDS 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 get this from System Information in the configuration tool. Restrictions: 1. All wireless access points in the wireless bridge need to support WDS. At time of publication, only Buffalo G54 and Apple Airport Extreme access points support WDS. 2.
Troubleshooting Setting up WDS; the long version: 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 first access point in the wireless bridge (this should be the DHCP server enabled access point if there is not already a routed wired network). 3. Click on the Advanced button. 4. The wireless settings page will appear.
Troubleshooting 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 Settings tab. 12. The wireless settings page will appear. Select the proper settings for the wireless network. Refer to the settings recorded from the first access point. All settings except for the SSID need to be identical amongst all access points in the bridge.
Troubleshooting 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 address (including the :’s). Please make sure the Wireless MAC address, and not the wired MAC address, is recorded. 22. Logout of the access point by clicking on Logout at the top of the page. Close the browser window. 23. Login to access point one again. 24.
Troubleshooting 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 occurred during the setup. WDS is a complicated bridging system with a lot of variables. If there are still problems with WDS configuration on the network, please contact Buffalo Tech Support (see pages 82 and 83).
