Introduction Congratulations on your purchase! With both a wired LAN router and a 811g wireless access point, the AirStation WHR-G54S Cable/DSL Router is perfect for linking your wireless devices with a wired network and each other. System Requirements • A high-speed (Broadband) Internet connection or existing local area connection. • A computer with a network connection (wired or wireless) and a good web browser.
Basic Setup Begin by finding a good place to set up your router/access point. consider: Some things to • You’ll need to be able to plug your internet connection into it, so it should go within reach of the LAN cable from your DSL or Cable modem. You’ll also want a power outlet nearby. • Keep the access point as central in your work area as possible. speed fall off with distance. • Higher is often better.
Getting Ready Make note of the AirStation’s wired MAC address. The LAN or Wired MAC address is the default SSID (wireless network name) of the AirStation. You can find it on the bottom of the AirStation. You may also wish to contact your ISP to ask if other information, such as global IP address, subnet mask address, default gateway address, DNS server address, or PPPoE parameters, is necessary to access your internet connection. Write down any necessary information that your ISP requires for connection.
Connecting your AirStation 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 WAN port. Initially, 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’s Ethernet adapter (NIC).
Log in to the Configuration Tool Launch a web browser on the computer that you’re going to use to configure the AirStation. Enter 192.168.11.1 into the URL field. Naturally, if you change your AirStation’s IP address, you’ll have to enter the new address instead. A window will open, prompting you to enter a User ID and Password. Enter root as the User name and leave the password field blank.
Detecting Your Broadband Connection Your AirStation’s SmartRouter technology will determine the type of internet connection you have automatically, and ask you for any needed information. If your ISP assigns IPs automatically (most cable providers do), their DHCP server will give your router an IP address. If additional login information is required to connect to the internet, the wizard will ask for it. Enter any required login information if asked.
Home This is the opening page of your AirStation’s configuration tool. You can always get to it from within the configuration screens by clicking on Home. From here, you can configure port mapping for your internet games, turn on UPnP for Windows (MSN) Messenger, configure your Firewall, setup Encryption, choose your Wireless channel, update your AirStation’s firmware, and reset your Internet connection’s configuration.
AOSS AOSS (AirStation One-Touch Secure System) is a simple system for configuring your wireless network securely. If your router and your client device are connected and both support AOSS, then making a secure wireless connection is very easy. Push the AOSS button on the top of your router and hold it in for a few seconds. The AOSS light will begin to flash amber. You now have two minutes to push the AOSS button on your client device and finish the connection.
AOSS Notes Some things to keep in mind • • • • Only one AOSS wireless client adapter can be configured with the AOSS router at a time. The buttons will need to be re-pressed to connect each additional AOSS wireless client adapter. It is not necessary to AOSS client devices that have already been configured via AOSS, unless significant changes have been made to the wireless network. Do not attempt to configure two separate AOSS networks at the same time, as it may cause undesired configurations.
Router/Access Point Mode This AirStation supports quickly changing the product from a wireless router to a conventional access point. Put your Airstation into Access Point Mode by moving the switch on the bottom of your AirStation from AUTO to BRI. This changes the default IP address of the AirStation from 192.168.11.1 to 192.168.11.100, and DHCP, NAT, and the WAN port are disabled. Access Point Mode might be desirable if you’re adding wireless capability to an existing network with a router.
Manual Client Configuration If your wireless client doesn’t support AOSS, you’ll have to configure it manually. From the Home page, click on the System Info tab.
System Info This page gives you all the information you might need to configure your non-AOSS wireless client. Probably you’ll just need the SSID, encryption type, and password. Consult your wireless client’s documentation for more information on configuring it if necessary. You can get here from Home by clicking the System Info tab.
AirStation Configuration Tool (Home) When you first open your AirStation Configuration Tool, it will take you to Home (see also page 11). From Home, you can configure port mapping for your internet games, set UPnP for Windows (MSN) Messenger, configure your firewall, setup encryption, choose your wireless channel, update your AirStation’s firmware, and reset your Internet Connection’s configuration. Clicking the Advanced tab gives you access to all of the AirStation’s configuration tools.
Internet Games (Port Mapping) Select any ports that need to be opened for your internet games to function correctly. Consult your game’s documentation for more information on what ports need to be configured.
Windows (MSN) Messinger/UPnP Windows (MSN) Messinger requires UPnP for proper operation. You may Enable UPnP here. UPnP may need to be configured on your PC as well. If you need to configure UPnP on your PC, the links at the bottom of the page have instructions for doing so on Windows ME and XP computers. Get to this page from Home by clicking on Windows (MSN) Messinger.
Firewall/Intrusion Detector From this page, choose the level of firewall security you desire. You may also choose to have alerts sent to a different PC, if you like. Click Next when done to restart the router. Get to this page from Home by clicking on Firewall/Intrusion Detector.
Wireless Encryption This page is available from Home by selecting Wireless Encryption. Here, you can manually select the type of wireless encryption you’d like to use. Your AirStation supports three different encryption schemes; choose the best one that all your clients support. Virtually all wireless clients support WEP. It’s a lot better than nothing. TKIP is much more secure than WEP, but slower. AES is even more secure than TKIP, and the fastest of all.
Wireless Channel This page is available from Home by selecting Wireless channel. With Auto Channel selected, your AirStation will choose the best channel available. Current channel will show the channel that your AirStation is currently using. You may also select any channel from 1-11 manually. Channels 1, 6, and 11 are non-overlapping. If multiple channels are in use in an area, select a different channel for your AirStation, as far away from the other channels being used as possible.
Firmware Update This page is available from Home by selecting Firmware update. Use Browse to select your firmware update file, and then click on Apply. Firmware update may take several minutes to complete. Don’t power down your AirStation until the diag LED has gone out.
Internet Connection (Multisession Reset) From Home, selecting the Internet Connection Wizard (Multisession Reset) tab will begin the Internet Connection Wizard.

Also on this page, under Advanced Settings, you may manually set the Default Gateway, DNS server, WAN MAC address, WAN format, and WEB port number. Click Apply when finished.
PPPoE Many DSL connections require a PPPoE connection in order to log in to an internet connection. Normally, the Easy Detection Wizard will help you configure that, but you may manually configure one here. Consult your ISP for more information on correctly configuring your PPPoE connection. To add a new PPPoE connection, click Edit Connection List. To choose your preferred connection, click on Edit Preferred Connection List.
LAN Config (LAN Port) Default for the LAN side IP address is 192.168.11.1. To add the AirStation to an existing LAN, specify a unique IPaddress, not used elsewhere in the network. The default Subnet Mask is 255.255.255.0. To connect AirStation to an existing LAN, specify the Subnet Mask that the LAN uses. If there’s more than one DHCP server on a network, disable all but one of them.
Advanced DHCP Settings This page offers the same DHCP settings as the previous one, and in addition, offers you the chance to change the Lease Period, Default Gateway, DNS servers, WINS server, and Domain Name. Click Apply when you have the settings the way you want them. To manually assign an IP address, click Manual Assignment.
DHCP Server (Manual Assignment of IP Address) To manually link a LAN address to a MAC address, enter them under Add Client Information and click Add. Current DHCP Client Information shows all LAN addresses currently assigned by AirStation’s DHCP. You may configure a specific client to always recieve the same IP address by clicking Manual Assignment to the right of its MAC Address. Clicking Delete returns a manually assigned client to normal DHCP operation.
Network Config (Route Info) By default, the AirStation receives RIP (Route Information Protocol) information only from your local network, and doesn’t broadcast RIP at all. For large, complicated network configurations, you may wish to modify this behavior. Click Apply when you have your desired configuration. Lower on the page, routing information is displayed. Click Edit Routing Information to add a new route manually.
Network Configuration (Edit Routing Information) To configure a route manually, enter its destination address and gateway. Enter a maximum number of hops allowable in Metric and click Add.
NAT You may disable Network Address Translation and IPsec passthrough by unchecking the appropriate Enable boxes. If you have a DMZ, enter its IP address in the IP Address of DMZ box. Incoming packets containing no recognizable destination port information will be redirected to the DMZ’s IP address. Click Apply when done. To set a NAT table entry manually, click Edit NAT Table.
NAT (Manual Entry) From this page you may manually add entries into the Address Translation Table. Click Add New Group when each is complete.

Network Configuration (Intrusion Detector) To enable intrusion detector, choose Enable or Enable (Apply packet filter rules) from the Intrusion Detector drop-down box. If packet filter rules are applied, packets will be filtered with packet filter rules before Intrusion Detector is applied. Blocking IP spoofing blocks packets from devices using an IP address that is not their own. In the Threshold Value box, enter the number of times an event has to occur before you receive notification.
UPnP You may disable Universal Plug and Play functionality by unchecking Enable here. Note that Windows (MSN) Messenger will not function correctly with UPnP disabled.
AOSS Clicking Start AOSS Sequence has the same function as pushing the AOSS button on the router: it initiates the AOSS process. If all your clients support AOSS, it’s very simple to set them up. Press the AOSS button on the router, or the one on this page, and then push the AOSS button on the client device. Each client device will have to be set up seperately. Wait for each AOSS process to finish before starting the next one. Consult your client device’s documentation for the location of its AOSS button.
802.11g (Basic) If you have a mixed mode network, with both 802.11b and 802.11g clients, it’s recommended that you check 11g protection to ensure that slower 11b clients don’t hog all available bandwidth. Choosing Auto for Wireless mode lets both 802.11b and 802.11g clients connect to the network. If you would prefer to allow only one or the other, you have those options as well. Two different framebursting modes are available.
802.11g (Security) Buffalo recommends that you choose the strongest form of encryption that’s supported by all your client devices. • WEP is a lot better than nothing, and almost every wireless device ever made supports it. • TKIP is slower than WEP but much more secure. • AES is the most secure of all, and the quickest as well. Use it if you can. Setting the key renewal period too short can decrease network performance. By default, the AirStation broadcasts its SSID.
Bridge/Repeater (WDS Bridging) To setup a bridge between two or more wireless access points, select Enable and click on Apply. For more on setting up WDS, see page 67, or click on Help at the top right corner of the screen.

Configuring a WDS Bridge Your AirStation’s WDS bridging capability allows you to extend the size of your wireless network by adding additional AirStations, all connected wirelessly. In this simple example, we’ll connect two AirStations in a wireless bridge. You may use these same steps to add additional bridges for greater coverage.* For easiest configuration, we recommend configuring all components in close proximity before deploying them to their final positions.
Configuring a WDS Bridge Connect a PC’s Ethernet port to another RJ-45 port on the main router (the first AirStation). You will use this PC to configure the settings of the AirStations. Here’s the whole setup, ready for initial configuration. * Note: Each AirStation may be part of 6 different bridges. Remember that each layer of bridges takes about half your total network speed, so avoid configuring daisy-chains more than 4 bridges long.
Configuring a WDS Bridge Once the AirStations are powered on, you will want to make sure that they are in factory default configuration. On the bottom of each, hold down the “INIT” button for three seconds. This will reset them to factory defaults. They will take 30-60 seconds to reboot afterwards. Power on your PC. Make sure that it is configured to “obtain an IP address automatically” from DHCP. Open a web browser and in the address field, enter 192.168.11.1.
Configuring a WDS Bridge The Web-Based Configuration Utility for your first AirStation will open. Click on the Advanced tab. On the left side menu, click on Wireless Config, and then Basic. Change the Wireless Channel from Auto to a channel. Make a note of the channel that you’ve chosen, because all of your wireless devices will need to be configured to use this same channel.
Configuring a WDS Bridge On the left-side menu, click on Wireless Config, and then Repeater. Repeater-Bridge (WDS) must be set to Enable. If it is not, change it to Enable in the drop down menu and click Apply. After the AirStation reboots, the screen will refresh. Click Edit Registered WDS Partners. Under Add New WDS Partner Access Point, enter the wireless MAC address of the second AirStation, the one that you want to form a bridge with.
Configuring a WDS Bridge Now, you need to configure the second AirStation with the MAC address of the first one. In your browser’s address field, enter “192.168.11.100”. This will take you into the Web-Based Configuration Utility for the second AirStation. Once again, the username is “root” and the password is blank.
Configuring a WDS Bridge In the Web-Based Configuration Utility, click on the Advanced tab, select Wireless Config, and choose Basic. Change the wireless channel to match the one you set for the first AirStation. Change Framebursting from 125 High Speed Mode to Framebursting or Do not use (whichever you chose for the first AirStation). For easy roaming, you may change the SSID to match the current SSID setting of the other AirStation. Click Apply. Your AirStation will reboot in 30-60 seconds.
Configuring a WDS Bridge Under Add New WDS Partner Access Point, enter the wireless MAC address of the first AirStation (available from the bottom of the first AirStation), with each pair of digits separated by a colon, e.g. MAC:000D0B10F779 would be entered 00:0D:0B:10:F7:79. Click New Partner when done. The AirStation will reboot, and when the screen refreshes, the first AirStation’s MAC address will be listed under Bridgeable Access Points. The two AirStations are now linked by a wireless bridge.
Configuring a WDS Bridge Once you can connect to each of your access points, you should configure WEP encryption. Without WEP, anyone within range of your access points can easily connect to your network. From within the second AirStation’s Web-Based Configuration Utility (192.168.11.100), click on Advanced, then Wireless Config, then Security.
Configuring a WDS Bridge Hexadecimal Input - 26 digits (Hex WEP128 104 bit, key should contain 26 characters A-F, 0-9) Hexadecimal Input - 10 digits (Hex WEP64 40 bit, key should contain 10 characters A-F, 0-9) Enter at least one encryption key in the first encryption key space. The key should match the format of the chosen WEP encryption type. Additional keys may be entered in boxes 2, 3, and 4. Click Apply when finished.
Troubleshooting WDS Most problems with setting up WDS are caused by incorrectly entering the MAC addresses into each AirStation’s Web-Based Configuration Utility. If you’re having problems, check the MAC address settings in both AirStations’s Web-Based Configuration Utilities. Each Airstation should be configured to be in a bridge with the other’s wireless MAC address. Confirm that all bridges are set to the same wireless channel.
Troubleshooting WDS Notes on WDS: 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. 3. Start the wireless bridge system with only two access points and then add more, one at a time. 4.
