Introduction

Congratulations on your purchase! The AirStation WZR-G240 MIMO Router uses multiple antennas

and Airgo Gen-3 MIMO (Multiple In, Multiple Out) technology to give you a faster, more reliable wireless network. The WZR-G240 also includes AOSS™, allowing you to set up a secure wireless network in minutes. The AirStation MIMO WZR-G240 is a great router and access point for multimedia streaming and other applications where performance and data integrity are crucial.

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. The

screenshots in this manual were taken with Firefox, but Netscape and Internet Explorer are also supported in versions 4.5 or later, and Safari 1.0 and later are supported with Macintosh OS X 10.2 and later.

AirStation WZR-G240 Package Contents

The AirStation WZR-G240 package contains the following items:

• WZR-G240 Base Station

• AC adapter and power cable

• CAT5 LAN cable

• Utility CD with Manual

• Quick Setup Guides

• Warranty Statement

Basic Setup

Begin by ﬁ nding 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. For instance, set it up on the top shelf of a bookcase rather than

the bottom one, if possible.

• Buffalo Technology recommends leaving the three antennas in their upright positions.

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.

Buffalo recommends using a wired network connection, where your computer is physically connected to the AirStation with a CAT5 straight cable plugged into one of the four LAN ports, to initially set up your router. This will avoid possible conﬁ guration problems with the wireless adapter on the computer being used to conﬁ gure the AirStation.

The computer used to conﬁ gure the AirStation should be set to obtain an IP address automatically using a DHCP server. The WZR-G240 has a default LAN IP address of

192.168.11.1 and Subnet Mask of 255.255.255.0.

Connecting your AirStation

1. Power down the Cable or DSL modem and the

computer which will be used to conﬁ gure 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). If you plan to initially conﬁ gure the AirStation wirelessly (not recommended), you may skip this step.

4. Power on your cable or DSL modem and wait one full minute, then power on the AirStation router and wait one full minute, and ﬁ nally, power on the computer which will be used to conﬁ gure the AirStation.

Power

WAN Port

LAN Ports

Launch a web browser on the computer that you’re

going to use to conﬁ gure the AirStation.

Enter 192.168.11.1 into the URL ﬁ eld. 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 Name and Password.

Enter root as the User Name and leave the password ﬁ eld 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. Contact your DSL provider for any missing login information.

If your DSL provider requires that PPPoE information be entered manually, see page

25.

Home

This is the opening page of your AirStation’s conﬁ guration tool. You can always get to it from within the conﬁ guration screens by clicking on

Home. From here, you can conﬁ gure port mapping for your internet games, turn on UPnP for Windows (MSN) Messenger, conﬁ gure your Firewall, setup Encryption, choose your Wireless channel, update your AirStation’s

ﬁ rmware, and reset your Internet connection’s conﬁ guration. As you explore the conﬁ guration tool, you can

usually get context sensitive help by clicking on the Help link at the top right of the page.

To go to Advanced Settings (page 25), click on the Advanced tab. To get the system information you need to set up a wireless client that doesn’t support AOSS, click on the System Info tab. See page 17 for more on Home.

AOSS

AOSS (AirStation One-Touch Secure System) is a simple system for conﬁ guring your wireless network securely. If your router and your client device are powered on and both support AOSS, then making a secure wireless connection is very easy.

First, push the AOSS button on the back of your router and hold it in for one second. The AOSS light will begin to ﬂ ash. Let go of the AOSS button. You now have two minutes to push the AOSS button on your client device and ﬁ nish the connection.

Second, push the AOSS button on your client device. Check your client device’s documentation for the location of its AOSS button.

After you’ve pressed both buttons, it will take about 15 seconds for the connection to complete. When it’s ﬁ nished, the AOSS light will glow a solid amber. You now have a secure network connection!

If you’ve already connected your AirStation to the Internet (page 10), your client devices will now be able to access the internet as well.

AOSS Notes

Some things to keep in mind with AOSS

The AOSS button is also the INIT button. Don’t hold the button down too long!

•

One second is sufﬁ cient. If you hold the button down for 5 seconds or more, AOSS will cease and the WZR-G240 will initialize all settings. You’ll then have to restart conﬁ guration from the beginning.

• Many AOSS clients have their AOSS button in software. If your client device doesn’t

have a visible AOSS button, look in its client software, or consult its documentation.

• AOSS connects your wireless clients to your access point. It doesn’t set up your

internet connection for you. To connect to the internet, you may still have to run your router conﬁ guration utility, even if you are using AOSS.

• Only one AOSS wireless client adapter can be conﬁ gured with the AOSS router at a

time. The AOSS button will need to be re-pressed to connect each additional AOSS wireless client.

• It is not necessary to AOSS client devices that have already been conﬁ gured via AOSS,

unless signiﬁ cant changes have been made to the wireless network.

• Do not attempt to conﬁ gure two separate AOSS networks at the same time, as it may

cause undesired conﬁ gurations.

• If an undesired client has connected via AOSS, it can be disconnected from within the

WZR-G240’s advanced conﬁ guration menus.

Manual Client Conﬁ guration

If your wireless client doesn’t support AOSS, you’ll have to conﬁ gure it manually. From the Home page, click on the System Info tab.

System Information Page

This page gives you all the

information you might need to conﬁ gure your non-AOSS wireless client. Probably you’ll just need the SSID, encryption type, and encryption key (password). Consult your wireless client’s documentation for more information on conﬁ guring it if necessary.

You can get here from Home by clicking the System Info tab.

AirStation Conﬁ guration Tool (Home)

When you ﬁ rst open your AirStation

Conﬁ guration Tool, it will take you to Home (see also page 11). From Home, you can conﬁ gure port mapping for your internet games, set UPnP for Windows (MSN)

Messenger, conﬁ gure your ﬁ rewall, setup encryption, choose your wireless channel,

update your AirStation’s ﬁ rmware, and reset your Internet Connection’s conﬁ guration. Clicking the Advanced tab gives you access to all of the AirStation’s conﬁ guration tools.

You can get back to Home from anywhere in the management tool by clicking on the Home button at the top left of the screen.

Let’s begin exploring advanced settings by clicking on Internet Games (Port Mapping).

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 conﬁ gured.

Windows (MSN) Messinger/UPnP

Windows (MSN) Messinger requires UPnP for proper operation. You may Enable UPnP here. UPnP may need to be conﬁ gured on your PC as well.

If you need to conﬁ gure 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 ﬁ rewall 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. Highly recommended if all of your wireless clients support it.

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 nonoverlapping. 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.

Channel Expansion reduces wireless overhead, giving your network faster throughput for clients that support it. If enabled, choose an Expansion Channel either 4 higher or 4 lower than your main 802.11g channel.

Firmware Update

This page is available from Home by selecting Firmware update. Use Browse to select your ﬁ rmware update ﬁ le, 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 Wizard (Multisession Reset)

From Home, selecting the Internet Connection Wizard (Multisession Reset)

tab will begin the Internet Connection Wizard.

The Internet Connection Wizard will only function correctly in simple networks, where your cable or DSL modem is plugged directly into your AirStation’s WAN port. If you have a complicated existing network that you’re adding the AirStation to, see page 56.
