5Work and play - further and faster! Eliminate dead spots and enjoy faster connections with vastly extended range from Buffalo Technology’s amazing wireless solution, the AirStation Draft-N Nniti Wireless Router & AP. 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-AG300NH Package ContentsThe AirStation WZR-AG300NH package contains the following items: • WZR-AG300NH AirStation• AC adapter and power cable• CAT5 LAN cable • Utility CD with Manual• Quick Setup Guides• Warranty StatementIntroduction
6Begin by 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.Basic Setup
7Make 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 type of setup will eliminate possible setup problems with the wireless adapter on the computer being used to congure the AirStation. The computer used to congure the AirStation should be set to obtain an IP address automatically using a DHCP server. The WZR-AG300NH has a default LAN IP address of 192.168.11.1 and Subnet Mask of 255.255.255.0.Getting Ready
81. Power down the Cable or DSL modem and the computer which will be used to con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 con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 nally power on the computer which will be used to congure the AirStation. If the red DIAG light on the AirStation is lit or ashing after several minutes of being powered on, please consult Buffalo Technology Technical Support.Connecting your AirStation
9Launch a web browser on the computer that you’re going to use to congure the AirStation.Enter 192.168.11.1 into the URL 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 ID and Password.Enter root as the User name and leave the password eld blank.Log in to the Conguration Tool
10Your 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 Detecting Your Broadband Connectioninformation 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.
11This is the opening page of your AirStation’s conguration tool. You can always get to it from within the conguration screens by clicking on Home. From here, you can congure port mapping for your internet games, turn on UPnP for Windows (MSN) Messenger, congure your Firewall, setup Encryption, choose your Wireless channel, update your AirStation’s rmware, and reset your Internet connection’s conguration. As you explore the con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.Home
12AOSSAOSS (AirStation One-Touch Secure System) is a simple system for conguring 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 top of your router and hold it in for a few seconds. The AOSS light will begin to ash amber. You now have two minutes to push the AOSS button on your client device and nish the connection. If you have a standalone client device, it will probably have a little red button labled “AOSS” on it. Push the button! About 15 seconds later, you’ll have a secure network connection. If your client device is a PC card, CardBus, or PCI adaptor, the AOSS button will probably be in its Client Manager Software. Check your client device’s user manual for instructions on where to push or click the AOSS button.After you’ve pressed both buttons, it will take about 15 seconds for the connection to complete. When it’s nished, the AOSS light witll glow a solid amber. You now have a secure network connection! standalone client devicePC card Client ManagerSoftware AOSS
13Some things to keep in mind with AOSS:• Only one AOSS wireless client adapter can be congured 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 congured via AOSS, unless signicant changes have been made to the wireless network.• Do not attempt to congure two separate AOSS networks at the same time, as it may cause undesired congurations.• If an undesired client has connected via AOSS, it can be disconnected from within the WZR-AG300NH’s advanced conguration menus.AOSS Notes
14This 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, or conguring your AirStation as part of a bridge setup. It is not suitable for most home congurations. If you plan to use the AirStation as an normal wireless router, make sure that this switch is in the normal (AUTO) position!To set up your AirStation as a bridge, ip the switch to BRI.Router/Access Point Mode
15If your wireless client doesn’t support AOSS, you’ll have to congure it manually. From the Home page, click on the System Info tab.Manual Client Conguration
16This page gives you all the information you might need to congure your non-AOSS wireless client. Probably you’ll just need the SSID, encryption type, and password.

41The SSID or network name can be changedby entering a custom SSID and pressingthe Apply button.802.11a (Basic)
42If you have a mixed mode network, with Draft-N, 802.11a clients, it’s recommended that you check 11n protection to ensure that slower 11a clients connect properly.802.11a (Advanced)
43Buffalo 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.802.11a (Security)By default, the AirStation broadcasts its SSID. This makes it easier for clients to connect to the AirStation. To disable broadcasting, uncheck this box.Privacy Seperator prevents wireless clients from being able to browse each other’s computers. Check Enable to turn it on.
44The SSID is the name of your wireless network. This is what you’ll see when performing a wireless scan or survey from a wireless client. You may change this to something easy to remember, like “MYNETWORK”.Channel Selection - You may nd it necessary to change the AirStation’s channel to avoid interference with other 2.4 Ghz sources, such as cordless phones, neighboring Wi-Fi networks, baby monitors, etc. By default, the Auto Channel mode will attempt to locate the clearest channel possible.Channel Bonding modes are specic for Draft-N. The 20 MHz mode uses less available wireless bandwith, which results in less interference to other 2.4 GHz wireless devices as well as slower wireless transfer speeds. The 40 MHz mode uses more bandwith, resulting in potentially more interference but signicantly more performance. Control Sideband instructs the AirStation to use channels towards the lower end of the spectrum or the higher end.802.11g (Basic)
45If you have a mixed mode network, with Draft-N, 802.11b and 802.11g clients, it’s recommended that you check 11n protection to ensure that slower 11b and 11g clients connect properly.Choosing Auto for Wireless mode lets Draft-N, 802.11b and 802.11g clients connect to the network. If you would prefer to allow only one of the modes to connect, you have those options as well.802.11g (Advanced)
46Buffalo 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.802.11g (Security)By default, the AirStation broadcasts its SSID.
