About the AirStation CD

The AirStation does not require any software to be installed on your computer for conﬁ guration. The AirStation CD contains product documentation, TightVNC Remote Control Software, and Buffalo’s Client Manager which provides AOSS functionality for any Buffalo client card or any Intel Centrino notebook.

It is the policy of Buffalo Technology to improve products as new technology, components, software and ﬁ rmware become available.

Please consult the AirStation wireless website (http://www.buffalotech.com/wireless) to download and install the latest ﬁ rmware for your product.

Follow these simple steps to connect the AirStation to your Broadband Internet connection allowing you to combine and share wired and wireless computers and printers with the high-speed internet connection.

Installation / Setup

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 Ethernet adapter’s (NIC) port. If you plan to initially conﬁ gure the AirStation via a wireless connection, (not recommended), you may skip this step.

4. Power on your cable or DSL modem, wait one full minute, Power on the AirStation router, wait

another full minute and then power on the com-

puter which will be used to conﬁ gure the AirStation. If the red DIAG light on the AirStation is lit or ﬂ ashing after several minutes of being powered on, please consult Buffalo Technical Support.

Installation / Setup

Introduction

Conﬁ guring the AirStation using a standard web browser requires basic wireless conﬁ guration knowledge. Setup includes manual wireless conﬁ guration and basic administrative management.

Setup Preparation

Make note of the AirStation’s wired MAC address (found on the underside of the WZR-RS-G54). It is also recommended you record any other broadband ISP information such as global IP address, subnet mask address, default gateway address, DNS server address and PPPoE parameters.

Setup Overview

Buffalo recommends using a wired connection, meaning your computer is physically connected to the AirStation with a CAT5 straight cable plugged into one of the four LAN ports This type of setup will eliminate possible setup problems due to any issues with the wireless adapter on the computer being used to conﬁ gure the AirStation.

A Web browser version 4.5 or later can be used to conﬁ gure the AirStation.

Advanced settings for security, ﬁ ltering and other features will be explained in later sections.

Antenna Installation

The WZR-RS-G54 has two internal antennas. One has a vertical orientation while the other has a horizontal orientation. This setup is ideal because it allows for proper antenna polarization with both desktop and notebook style wireless adapter antennas.

However, it may be necessary to increase your range further by installing an external, higher-gain antenna. External antennas come in all shapes and sizes. Antennas also come with different connectors. The WZR-RS-G54 has an ‘MC Connector’ on it. Thus, the antenna must also have an MC connector.

To install the antenna, slide the antenna connector door on the back of the WZR-RS-G54 to the right. This will expose the MC Connector. Attaching the antenna is simple, just insert the antenna’s MC Connector into the WZR-RS-G54’s MC Connector and ﬁ rmly push it in until it snaps into place. Once snapped, the antenna’s connector will swivel with ease. It is important not to push the antenna connector in at an angle.

To remove the antenna, pull the antenna connector out. It is important not to pull the antenna connector out at an angle.

AOSS

AOSS (AirStation One-Touch Secure System) is a simple, one-touch setup for connecting wireless clients to an access point while setting up the most secure possible connection. Users no longer need to worry about choosing the proper security protocols, IP addresses, or SSID's. The intelligence of AOSS determines the most optimal connection and conﬁ gures itself in seconds.

■ NOTE: AOSS automatically creates a secure connection between your AOSS Access Point and client. You must have an AOSS enabled wireless client device to use the AOSS features of your AOSS Access Point/Router. Intel Centrino supports AOSS by installing Buffalo's Client Manager software.

◗ Conﬁ gure your WZR-RS-G54’ internet

connection by referring to the instructions in the WZR-RS-G54’ Quick Setup Guide.

◗ Once the WZR-RS-G54 has been conﬁ g-

ured, follow the directions to install your wireless client device and its drivers if necessary. Certain wireless client adapters require client software to conﬁ gure them. If your device has a Client Manager, then install it as well.

■ NOTE: If the wireless client adapter is installed on a PC, then the AOSS client manager will need to be installed as well. If your wireless client adapter is a standalone device that does not require a PC, then just power up the device.

Standalone Devices: Ethernet Converters and Access Point Bridges Client Manager Devices: CardBus, USB, and PCI Adapters.

◗ Now that the WZR-RS-G54 and wireless client adapter

are installed, you can use AOSS to conﬁ gure them.

◗ To begin the conﬁ guration, press the AOSS button on

the side of the WZR-RS-G54 for 3-5 seconds. The orange AOSS light will begin to ﬂ ash rapidly when the AOSS mode has been enabled. You can stop pressing the button at this point.

■ NOTE: AOSS mode will stay active for a period of two minutes. This is the time-slot required to initiate AOSS on the wireless client adapter.

◗ Refer to your wireless client adapter's AOSS supplement

to initiate the wireless client adapter's AOSS mode.

◗ Once the client adapter has ﬁ nished communicating

with the AOSS router, the orange light will stop ﬂ ashing and become solid. This indicates that the AOSS process has completed and the devices are now using AOSS. It typically takes 15-60 seconds for the entire AOSS process to complete. Please refer to your wireless client adapter's

supplement for the remainder of the setup.

AOSS

Additional AOSS Information:

◗ Only one AOSS wireless client adapter can be conﬁ gured to the AOSS router at a time. Thus,

the button will need to be repressed for each additional AOSS wireless client adapter that will be connected.

◗ 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-RS-

G54’ advanced conﬁ guration menus.

ters for the SSID (case sensitive). By default the SSID is the LAN Mac address of the AirStation.

■ Note: Roaming - When multiple AirStations have an identical SSID, WEP key (if WEP is used), (and channel in WDS mode) , client computers may Roam between the AirStations.

Wireless Channel - Select the channel used for wireless communication. There are 11 overlapping channels. Channels 1, 6 and 11 are non-overlapping. The ‘Auto-Channel’ option is recommended, as it constantly assesses the best available channel for the AirStation to operate on.

Set up LAN connections.

Wireless Settings

Wireless Function - Enable or

disable wireless LAN computer communication.

SSID - Allows administrator to alter the SSID of the AirStation. To communicate with a speciﬁ c AP only, the AP’s SSID must be entered in the client computer. The client computer looks for the speciﬁ c AP (or SSID) for wireless communication. Use up to 32 al pha nu mer ic charac-

Advanced Settings

If there are multiple APs in close proximity using the same channel, there may be interference. In this case, change to a non-overlapping channel.

Privacy Separator - Enable or disable communication between wireless clients. If you choose to use this feature, every wireless client that is associated to the AirStation will not be able to communicate with any other wireless clients.

■ Note: If this function is used, wired clients can still communicate with wireless clients.

BSS (Basic Service Set) Basic Rate Set - The transmission data rates offered by the AirStation. It is recommended to use the ‘Default’ selection to accomidate 802.11 and 802.11b rate sets. It is NOT recommended to use the ‘All’ selection, as some devices may not understand all of the rate sets offered by the AirStation.

Frame Bursting - This function increases 802.11g communication throughput by transferring packets more efﬁ ciently. The following conditions affect this function:

• The wireless LAN client adapter must support Frame Bursting (and it must be enabled). If the wireless LAN client adapter does not support Frame Bursting, or Frame Bursting is not enabled, then it will operate at non-Frame Bursting speeds.

125 High Speed Mode - This function further increases 802.11g communication. Rate sets up to 125 Mbps are offered to clients.The following conditions affect this function:

• The wireless LAN client adapter must support 125 High Speed Mode (and it must be enabled). If the wireless LAN client adapter does not support 125 High Speed Mode, or it is not enabled, then it will operate at regular 802.11g speeds.

It is recommended to leave 125 High Speed Mode enabled as it can only help throughput, not hurt it.

Advanced Settings

802.11g Protection - This enables protection mechanisms for when 802.11b clients join the network. It enables CTS (Clear-to-Send)

DTIM Period - An access point transmits beacon signals to nearby clients at a preset interval. This parameter sets the beacon transmission interval time (1-255 seconds). Se lec tion of a larger number may conserve energy for the client computer (when client power management is enabled), but may delay wireless communication. The default value of 1 is recommended.

Wireless Output Power - Conﬁ gure output power of the AirStation. Decrease wireless output power to shrink the wireless communication range. The default setting of 100% is recommended unless decreased range is desired

Broadcast SSID - Enable or Dis-

able the SSID (SSID) from being broadcasted. If denied, the AirStation will not be found unless the speciﬁ c AirStation’s SSID is entered in the client computer manually.

Data Encryption - Disable to have no encryption of the wireless data. This will make accessing the AirStation and the network very easy. It is im-

Advanced Settings

portant to note, that without encryption it is easy for strangers to connect to your network, especially if the AirStation is broadcasting its SSID.

Select the type of data encryption:

• Disabled - Disable data encryption.

- WEP - Uses WEP encryption. Encryption key should be entered.

- TKIP - Uses TKIP (Temporal Key Integrity Protocol) for data encryption.

The encryption key is renewed every “Re-key interval” when “TKIP” is selected.

WEP - When the WEP (Wired Equivalent Protection) encryption standard is implemented into a wireless network, a WEP key is used between the client and access point to successfully encrypt, transmit and decrypt data. For this reason, the same WEP key must be used for communication between the client and the AirStation.

An access point and client may both carry multiple WEP keys. It is necessary for not only the WEP keys to match, but also the WEP key’s order. If a wireless client cannot support multiple WEP keys, the AirStations must be conﬁ gured to transmit key number 1 for a connection to take place.

Examples of WEP key:

64-bit ASCII: 5 digits of alphanumeric characters, “ab34Y”

128-bit ASCII: 13 digits of alphanumeric characters, “123456abcdef7”

■ Note: ASCII WEP keys are case sensitive.

64-bit HEX: 10 digits, using characters 0-9 and a-f, “00234ABCDE”

Advanced Settings

128-bit HEX: 26 digits, using characters 0-9 and a-f, “20123456789abcdeabcdeabcde”

TKIP - TKIP (Temporal Key Integrity Protocol) is a WEP expanded encryption technique. TKIP has greatly improved WEP’s weaknesses by rotating secret keys between every packet. TKIP uses WPA-PSK (pre-Shared Key).

Characteristics:

- The Initialization Vector is expanded from 24-bits to 48-bits.

- The Initialization Vector is randomized.

- Uses a different RC4 key for every packet.

AES - AES further improves TKIP by using AES (Advanced Encryption Standard) encryption method. Due to its hardware co-processor, AES uses the toughest encryption without sacriﬁ cing throughput like WEP and TKIP.

TKIP & AES require an 8 to 63 character passphrase in ASCII or 64 digits hexadecimal key.

Example 1: [ airstation -WPA-PSK ]

Example 2: [0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef]

WPA Group Rekey Interval - When TKIP is selected, the encryption key is renewed at this interval. This interval is in seconds; the range of acceptable values is 0-3600.

If 0 is entered, the key is never renewed.

■ Note: The lower the rekey interval, the more often a rekey occurs. Setting a low rekey interval may affect performance negatively.

Advanced Settings

IEEE802.1x/EAP authentication (WPA) - Conﬁ gure Authentication and WPA Settings.

Disable - Do not use any RADIUS Server based authentication.

Enable - Authorized clients access this AirStation via a RADIUS Server.

Use 802.1x/EAP to authorize every wireless client who wants to access the AirStation by using

802.1x/EAP and a RADIUS Server. The RADIUS server provides login information for every user establishing a more secure system than TKIP or other ﬁ xed encryption key methods. This also reduces the amount of necessary key maintenance.

A RADIUS server is necessary for IEEE802.1x/EAP authentication. Enter [RADIUS Server], {RADIUS Port] and [RADIUS Key] information.

PPTP Client

This feature allows remote users to establish a PPTP VPN session to share resources betwenn networks in a secure environment.

You will need to have an account and have permission from the network administrator to connect as a PPTP client.

Select ‘Enable’ to turn the PPTP client on.

Input the IP address of the VPN Server as well as the username

and password.

Advanced Settings

Connecting PPTP Networks: For routing information to be accurate, you will be required to specify the routes of the VPN server’s network you are connecting to. This information will need to be supplied by the network administrator of the network in which you are connecting.

Routes should be added respecting subnets. For instance, if the network you are connecting to is in the 192.168.7.* subnet, then you should enter the IP Address as 192.168.7.0 (0 meaning the entire subnet). The subnet in this case would be 255.255.255.0.

For additional help with setting up the PPTP client, please consult the on-screen help balloons by pressing on the ‘Question Mark’ graphics next to each setting. In addition, consult with the network administrator of the network you are connecting too. In the event that you are using two WZR-RS-G54’s to create a secure tunnel, then both devices will have to be setup as PPTP Clients and as PPTP Servers. Due to the many different VPN servers and supported conﬁ gurations, we cannot provide more speciﬁ c setup instructions regarding the PPTP Client.

updates to a third party server. This means that you will always be able to ﬁ nd your network by way of a Dynamic DNS hostname; regardless of your IP Address. This feature is critical when using the Remote Gateway features of this router as it allows your users to always be able to ﬁ nd and connect to your network via a vanity hostname. It is a requirement that you enroll in one of the two Dynamic DNS providers we offer. TZO (Paid Service) and DynDNS (Free Service) are two of the most popular Dynamic DNS providers. Please see their respective web pages (http://www.tzo.com & http://www.dyndns.org) to create an account and learn more. Once you have created an account at one of the sites, then you can Enable the Dynamic DNS Function.

From the pull-down menu select the service you just subscribed to.

Dynamic DNS is one of the most effective ways of being able to locate your network

from anywhere on the internet anytime. Traditionally, IP Addresses and network information from your ISP change from time to time. When this change happens you can no longer

access your network by IP Address. Dynamic DNS is software that runs on your router that constantly sends network

Host Name - Input the domain host name set on the dynamic DNS server. For example: if the domain you wish to use is [buffalo.dyndns.org] then the host name would be buffalo. The host name may be 64 alphanumerical characters including hypens.

Domain Name - Input the domain name set on the Dynamic DNS server. If the domain you wish to use is [buffalo.dyndns.org] then the domain name would be dyndns.org. The domain name may be up to 64 alphanumeric characters including hyphens and periods.

User Name - Enter the account user name for the Dynamic DNS service you use. Up to 64 alphanumeric characters or symbols may be used.

Password - Enter the account password set on the Dynamic DNS service you use. Up to 64 alphanumerical characters or symbols may be used. For conﬁ rmation purposes the password must be entered twice.

Expiration - This setting cannot be changed from its default setting. The default setting works for both TZO and DynDNS.

IP Address Renewal Interval - With certain Dynamic DNS servers, the registered data has a set period of time it stays active. After this set period the Dynamic DNS hostname is no longer valid This period of time speciﬁ es the AirStation to renew your Dynamic DNS hostname after this many days. This prevents the Dynamic DNS service from removing your hostname. Caution: Dynamic DNS Services do not like being updated very frequently. In fact, some services will cancel your subscription if you renew too often. It is recommended to use 24-35 days in this ﬁ eld as it is an acceptable amount of time for a renewal, however, it is not too often that the Dynamic DNS service will cancel/block your hostname. Additionally, anytime your network information changes from your ISP, the Dynamic DNS service will automatically update, so setting this variable extremely low is not required.

Network

Service List

The Network Service List is the control center for your network. From within your LAN or from anywhere in the world with a VPN connection (See VPN Quick Setup Guide) you can access this control center. From this control center you can access convenient and easy to use services including: File Sharing, Remote Control/Access of PC’s, Wake-On-LAN, FTP Servers, and Web Servers. To learn more about each independent feature, click on the ‘Question Mark’ logo next to ‘Network Service List’. It has a lot of informative information regarding the services.

This hosts page can be reached by typing this URL into any browser connected to the network: http://XXX.XX.XXX.XXX/hosts.htm (where XXX.XXX.XXX.XXX is the local IP Address of the AirStation; by default this address is 192.168.12.1). Connecting to the VPN Server is easy, just launch the PPTP client as instructed in the VPN Quick Setup Guide and use the Dynamic DNS hostname as the VPN address.

Network Service List

For easier access to the Network Service List, the Dynamic DNS hostname can be used for access to the AirStation. However, for this to occur the ‘Remote Management Port Number’ must be conﬁ gured on ‘Page 43’. By entering the value ‘80’ into the ‘Remote Management Port Number’ the Network Service List can be accessed by typing: http://hostname.dyndns.org/hosts.htm -OR- http://hostname.tzo.com/hosts.com depending on the service you’re subscribed with.

You can also log into your network service list by just typing: http://hostname.dyndns.org OR- http://hostname.tzo.com depending on your service. You will be prompted for your user name and password. Once entered, you can click on the large ‘Network Service List’ link. It is not recommended that you give this username and password out to guests; this method of connection should only be utilized by yourself or the administrator of the network.

NOTE: By allowing remote management over a port number you allow access into your AirStation from the Internet without a VPN connection. This is a potential security risk especially if you have not setup an administrator password on the AirStation. Even with a password set, a user on the internet could log into your Network Service List and see all of the information regarding your network. Fortunately they would NOT have access to remote control, ﬁ le sharing, or Wake-On-LAN, but they will still be able to see what computers and devices are on your network. For some this may be considered a security risk.

File & Printer Sharing - Audio/Video Playback

The Shared Files icon on the Network Service List gives you access to a PC or network device’s shared ﬁ les and printers. For Windows PC’s, File and Printer sharing must be setup properly before this service will work. On Network Storage Centers like Buffalo’s LinkStation, the Shared Files icon should work with little to no conﬁ guration. Please consult your Windows documentation to learn more about setting up File and Printer Sharing.

After clicking on the Shared Files icon you will see the available shared ﬁ les and printers. Printing: To print you can right click on a shared printer and press the ‘Connect’ button to install it as a printer on your computer. You can also drag a document, image, or text ﬁ le directly over the printer share and it will connect to the printer and print it. Thus, you can drag a Microsoft Word Document over the shared printer and it will print out on the printer in the remote location. Files: To access ﬁ les, double click on the ﬁ le or folder icon just like you would on your local machine. Files can be moved, copied, and renamed normally as well.

Audio/Video Playback*: To play audio or video ﬁ les through shared ﬁ les just double click on the audio or video ﬁ le you would like to play or select multiple ﬁ les and create a playlist.

* Streaming audio or video over the internet requires an internet connection sufﬁ cient enough to move the necessary amount of data. For instance, to stream a 128kbps MP3, a 150k or greater internet connection would need to be present on the remote and local side. Video often requires a faster internet connection. Most broadband DSL/Cable connections will have no problem streaming audio and most video ﬁ les.

Remote Control - TightVNC

TightVNC is the recommended Remote Control Software. This icon will appear on any computer on the Network Service List that is running the VNC software. This icon provides a one-click process to obtaining access to the PC.

Installing TightVNC Software for the Desktop: Installing TightVNC is very easy, just insert the CD-ROM that came with your AirStation product and install the software. The on-screen menus will guide you through the setup process.

Non-Windows Platforms: TightVNC utilizes the open-source VNC standard, thus any VNC software will work with the AirStation. Currently only TightVNC and Windows are supported but customers can install other open-source VNC applications for Macintosh, Linux, and other systems. If the server runs on port 5800 then the ‘VNC Remote’ icon will appear on the Network Service List.

Additionally, there are VNC comptible clients for all systems including PalmOS and PocketPC. Thus, with PPTP VPN connection software, a handheld user (PalmOS and PocketPC) could theoretically connect in and control their home or ofﬁ ce PC’s from their handheld; assuming the handheld has some sort of internet connection. Buffalo Technology (USA) Inc. does not support users in making VNC work in anything but Windows.

Remote Control - TightVNC

Once you click on the ‘VNC Remote’ link you will be prompted for a password. If a password was not set during the installation, then this step may not occur. Enter the password and press the ‘OK’ button.

It is recommended to change the remote PC’s desktop size to 800x600 for the best viewing experience. This change can be made after connecting to the remote PC by right clicking on the desktop, selecting properties, and pressing on the ‘Settings’ tab.

Once logged on, you will have full, complete control over the PC in question. On the top bar there are a series of buttons that perform various tasks:

Disconnect: Ends the TightVNC remote control session immediately. Options: Brings up the options menu (see below). Clipboard: Brings up the remote PC’s clipboard so you can copy/paste

into the connecting machine. Send Ctrl-Alt-Delete: Sends an Alt-Ctrl-Del signal to the remote computer Refresh: Refreshes what is on the screen

There are several options for TightVNC. It is recommended to leave them all at their default values. However, the following settings may be changed if desired: JPEG Image Quality: Lower number = faster connection; lower image quality. Higher number = slower connection; better image quality. View Only: If enabled, you can only see what happens on the screen, not interact with the desktop.

Remote Control - TightVNC

There is a TightVNC client available on the CD-ROM that came with your AirStation. It provides more conﬁ guration options including screen scaling.

Troubleshooting

Troubleshooting WDS (Step-by-Step Instructions)

The 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 document this is under the ‘System Information’ section of the conﬁ guration web page. For proper setup, please continue reading this document.

Problem:

Communication problems with WDS (wireless bridging/repeating).

Cause:

WDS is a very complex bridging system, and it is not part of the 802.11b or 802.11g standard.

Restrictions:

Please verify that the following conditions are met (if just one condition is not satisﬁ ed, then WDS cannot be used on the wireless network):

1. All wireless access points in the wireless bridge need to be from the same vendor (e.g. all Buffalo access points).

(At time of publication, the Apple Airport Extreme WILL work in WDS with Buffalo G54 access points.)

2. No single access point can communicate with more then six other access points in the wireless bridge.Good Practices:proper location.

Troubleshooting

The following is a list of good practices with WDS:

1. Start the wireless bridge system with only two access points and then add more access points.

2. Setup all access points in the wireless bridge in close proximity before they are deployed to their

proper location.

3. Only one access point in the wireless bridge should be serving DHCP and routing services unless a routed wired network exists.

Proper Setup:

Please follow the following steps to properly setup WDS.

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 make sure the SSID settings need to be identical as well). Press the ‘Set’

button if any changes are made.

(If the IP address was changed, then reconnecting to the access point for conﬁ guration will require ac-

cessing it via its new IP address in a web browser (e.g. http://NEW_IP_ADDRESS).

Troubleshooting

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 as default.

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 ad-

dress (including the :’s). Please make sure the MAC address is recorded from the Wireless section and not the other sections.

9. 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’ button.

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 make sure the SSID settings need to be identical as well).

13. Click on the ‘LAN port’ link on the left.

14. Make sure that the ‘LAN side IP address’ ‘IP address’ setting is different then 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 ‘Do not use’ or to ‘Disabled’. Press the ‘Set’ button when ﬁ nished.

Troubleshooting

15. Click on the ‘Wireless bridge (WDS)’ link on the left.

16. Enable the WDS function and press the ‘Set’ button.

17. Enter the Wireless MAC Address of the ﬁ rst access point (which was recorded on Step 8) into the

ﬁ eld that say ‘MAC Address of AirStation(Wireless)’ (include the :’s). Press the ‘Add’ button.

18. The Wireless MAC address inputted on the step above will appear in the ‘Connected AirStation’ table. Please check that the checkbox under enable is checked, and then press the ‘Enable marked item’ button.

19. 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 ad-

dress (including the :’s). Please make sure the MAC address is recorded from the Wireless section and not the other sections.

22. Logout of the access point by clicking on the ‘Logout’ link on the left. Close the browser window.

23. Login to access point one again.

24. Click on the ‘Advanced’ button.

25. Click on the ‘Wireless bridge (WDS)’ link on the left.

26. Enable the WDS function and press the ‘Set’ button.

27. Enter the Wireless MAC Address of the ﬁ rst access point (which was recorded on Step 21) into the

ﬁ eld that say ‘MAC Address of AirStation(Wireless)’ (include the :’s). Press the ‘Add’ button.

Troubleshooting

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.

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 oc-

curred during the setup.

WDS is a complicated bridging system with a lot of variables. If there are still problems with WDS con-

ﬁ guration on the network, then please call our 24/7 technical support line at 1-866-752-6210.
