Introduction Congratulations on your purchase! With both a wired LAN router and a 811g wireless access point, the AirStation WHR-G125 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.
Initial Setup Begin by finding a good place to set up your router/access point. Some things to consider: • 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. Signal strength and speed fall off with distance. • Higher is often better.
Connecting your AirStation Power to outlet or surge protector PC Cable or DSL Modem
Setup with AirNavigator CD For a simple installation, you may use the AirNavigator CD in your package to step you through configuration. Insert the CD in the drive of your computer and follow the directions. The installation program will step you through connecting your computer to the AirStation and the Internet.
Manual Configuration To configure your router manually, use a wired connection to your computer. Once you’ve connected to the internet through the router, you may switch to a wireless connection if desired. The computer used to configure the AirStation should be set to obtain an IP address automatically using a DHCP server (this is Windows’ default). The WHR-G125 has a default LAN IP address of 192.168.11.1 and Subnet Mask of 255.255.255.0. 1.
Log in to the Configuration Tool Launch a web browser on the computer that you’re using to configure the AirStation. The first time your router is powered on, the window below should open automatically. To open it manually, you may enter your routers IP addrees (192.168.11.1 by default) into the URL field. 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.
Connecting Wireless Clients to the Access Point To connect wireless devices to the AirStation, you may either enter the SSID and encryption key manually, or you can use AOSS. For more information on AOSS, see pages 14 and 15. Consult your wireless clients’ manuals for instructions on configuring them manually. You can get SSID and encryption information from the AirStation’s initial setup screen, as shown above.
Basic Setup Page You can get back to the Setup page from anywhere in the configuration screens by clicking on the Setup tab in the top left corner. From here, you can rerun the Internet Connection Wizard, change your router mode, initiate AOSS or WPS, and see your wireless SSID and encryption settings. Context sensitive help is available on the right side of each page.
Navigating the Menus The menus in the Configuration Tool let you change your AirStation’s settings. To navigate settings, choose a category at the top of the page and then a submenu below. Settings will appear on the left, help files on the right. This example shows the WAN/LAN category with the WAN submenu item selected. Categories Submenus Individual Settings Help and Instructions The following pages show examples of some screens from the configuration utility.
Initialize/Reboot The Initialize/Restart page can be reached by choosing the Admin Config catagory tab and then clicking on the Initialize/Restart submenu. Click Restart Now from this page to restart your AirStation. Click Initialize Now to restore your AirStation to factory defaults and restart it. You may also initialize your AirStation by holding down the Reset button for 3 seconds.
AOSS You can get to this page by selecting the Wireless Config category and choosing the AOSS submenu. The blue AOSS button at the top left of the page has the same function as the physical AOSS button on the top of 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.
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 installed and both support AOSS, then making a secure wireless connection between them is very easy. Push the AOSS button on the side 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 with AOSS: • 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.
Router Mode This AirStation supports quickly changing the product from a wireless router to a conventional access point. For normal use, leave the “Router” switch in the ON position. If the Router switch is moved to OFF, the default IP address of the AirStation changes from 192.168.11.1 to 192.168.11.100, and DHCP, NAT, and the WAN port are disabled. Turning this switch off might be desirable if you’re adding wireless capability to an existing network with a router.
Encryption and Security By default, encryption is not enabled on the AirStation unless you used AOSS to perform your setup. Anyone within range can easily connect to your wireless network. This might not be what you want. Buffalo recommends enabling encryption and setting a password for access to your network. This is easy to configure from within the AirStation’s configuration tool. Select the Wireless Config tab and the Security submenu.
Encryption and Security Many kinds of encryption are available. WEP works with almost everything. WPA2-PSK is much more secure. Choose the strongest method of encryption that works with all of your wireless devices. If you must use WEP, it is available under “Wireless Encryption”. Enter a network key (“password”) for this connection. Write down your password and put it in a safe place. You will not be able to connect wireless devices to your network without this password.
Encryption and Security Each of your wireless clients will need your password to connect to the network. Click on the wireless icon in your computer’s systray, or this message if it pops up. Any wireless networks available in the area will be listed as available. Click on your wireless network SSID so that it turns blue and the click on Connect at the bottom right.
Encryption and Security Enter your network key (“password”) twice and click Connect. Repeat for each Windows XP computer that connects to your network wirelessly. Other wireless devices may have different configuration requirements. Consult their documentation for instructions on how to enter your network key and connect them to your wireless network.
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 Router switch from ON to OFF. 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 (“Internet”) port. 3. Open LAN Settings - LAN Port Settings and configure the following settings: IP Address =[192.168.11.137] (Specify an unused network address from the existing LAN.

125/300* High Speed Mode * When operating in High-Speed Mode, this Wi-Fi device achieves an actual throughput of up to 34.1 Mbps, which is equivalent to the throughput of a system following 802.11g protocol and operating at a signaling rate of 125 Mbps. 300 Mbps is the link speed when using Draft-N mode. It represents actual wireless data speeds, including overhead. Because the overhead is not available for user data transfer, usable wireless throughput will be substantially slower.
