52The 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.System Information
53Here you can choose what information gets logged and see recent log entries.Log Information
54Here, you can see the packets and errors for each of your networks.Packet Traffi c Information
55Client Monitor shows you a list of all clients currently connected to the wireless network.Client Monitor
56To 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.Ping Test
57Connecting to a Preexisting Network Add an AirStation without changing your existing LAN confi guration1. 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 confi gure the following settings: IP Address =[192.168.11.1] (Specify an unused network address from the existing LAN.) Subnet Mask=[255.255.255.0] (Use the same Subnet Mask as the existing LAN.) DHCP Server Function=[Disable] 4. Restart PC.
58The 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. If your antenna has a different kind of connector, you’ll need an adaptor.To install a different antenna, unscrew the stock antenna from the RP-SMA connector on top of the AirStation, and screw on the connector or adaptor from your new antenna.

67Troubleshooting WDSThe 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 confi guration 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. No single access point can communicate with more then six other access points in the wireless bridge.Good Practices:1. Start the wireless bridge system with only two access points and then add more, one at a time. 2. Setup all access points in the wireless bridge in close proximity before deploying them to their fi nal location.3. Only one access point in the wireless bridge should be serving DHCP and routing services unless a routed wired network exists. Troubleshooting
68Setting 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 fi rst 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. 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 set the SSID settings identically as well. Press the Set button if any changes are made. (NOTE: If the IP address was changed, then reconnecting to the access point for confi guration will require accessing it via its new IP address in a web browser (e.g. http://NEW_IP_ADDRESS). Write down the new IP address carefully if you changed it, and put it in a safe place!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 at their defaults. 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 colons). Please make sure the MAC address is recorded from the Wireless section and not the other sections.Troubleshooting
699. 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 fi rst access point. All settings except for the SSID need to be identical amongst all access points in the bridge. If roaming is desired, then set the SSID settings identically as well.13. Click on the LAN port link on the left. 14. Make sure that the LAN side IP address setting is different than that of the fi 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 fi rst access point. Thus, if access point one’s address is 1.1.1.1, then access point two’s 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 fi nished. If the IP address was changed, then reconnecting to the access point for confi guration will require accessing it via its new IP address in a web browser (e.g. http://NEW_IP_ADDRESS).15. Click on the Wireless bridge (WDS) link on the left. 16. Enable WDS and press the Apply button. If desired, move the switch on the bottom of the WHR-HP-G54 from AUTO to BRI to disable normal router functionality (optional).17. Enter the Wireless MAC Address of the fi rst access point (which was recorded on Step 8) into the fi eld MAC Address of AirStation (Wireless) (include the colons). Press the Add button. 18. The Wireless MAC address inputted on the step above will appear in the Connected AirStation table. Confi rm that enable is checked, and then press the Apply button.Troubleshooting
7019. 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. Click on the Advanced Settings tab.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 fi rst access point (recorded in Step 21) into the fi eld that says MAC Address of AirStation(Wireless) (include the :’s). Press the Add button.28. The Wireless MAC address inputted on the step above will appear in the Connected AirStation table. Please check that the checkbox by enable is checked, and then press the Apply button.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. Troubleshooting
71 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 confi guration on the network, please contact Buffalo Tech Support (see pages 82 and 83). Troubleshooting
