Installation / Setup

Introduction

Conﬁguring the AirStation using a standard web browser requires basic wireless conﬁguration

knowledge. Setup includes manual wireless conﬁguration and basic administrative management.

Setup Preparation

Make note of the AirStation’s wired MAC address (found on the underside of the WHR-G54S). 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 conﬁgure the AirStation.

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

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

Installation / Setup

The WHR-G54S has one hoip antennas. This setup is ideal be-

cause it allows for proper antenna polarization with both desktop

and notebook style wireless adapter antennas.

Internal Antennas

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 conﬁgures 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.

◗ Conﬁgure your WHR-G54S’ internet con-

nection by referring to the instructions in

the WHR-G54S’ Quick Setup Guide.

◗ Once the WHR-G54S has been conﬁg-

ured, follow the directions to install your

wireless client device and its drivers if

necessary. Certain wireless client adapt-

ers require client software to conﬁgure

them. If your device has a Client Man-

ager, 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 WHR-G54S and wireless client adapter are

installed, you can use AOSS to conﬁgure them.

◗ To begin the conﬁguration, press the AOSS button on the

top of the WHR-G54S for 3-5 seconds. The orange AOSS

light will begin to ﬂash 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 ﬁnished communicating

with the AOSS router, the orange light will stop ﬂashing

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 conﬁgured 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 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.

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

G54S’ advanced conﬁguration menus.

LAN Settings

Set up LAN connections.

Wireless Settings

Wireless Mode - 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 comput-

er. The client computer looks

for the speciﬁ c AP (or SSID) for

wireless communication. Use

up to 32 al pha nu mer ic charac-

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 overlap-

ping channels. Channels 1, 6 and 11 are non-overlapping. The ‘Auto-Channel’ option is recom-

mended, as it constantly assesses the best available channel for the AirStation to operate on.

Advanced Settings

Wireless

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 recom-

mended to use the ‘All’ selection, as some devices may not understand all of the rate sets offered by the

AirStation.

Frame Bursting Mode - This function increases 802.11g communication throughput by transferring pack-

ets more efﬁciently. 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.

High Speed Mode - This function further increases 802.11g communication. The following conditions af-

fect this function:

• The wireless LAN client adapter must support High Speed Mode (and it must be enabled). If the wire-

less LAN client adapter does not support High Speed Mode, or it is not enabled, then it will operate at

regular 802.11g speeds.

It is recommended to leave 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 net-

work. 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 num-

ber 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

Wireless LAN Security

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-

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 conﬁgured 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 sacriﬁcing

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 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

IP and Subnet Mask for the

LAN side of the AirStation.

■ Note: If the AirStation’s IP

address is changed, the con-

ﬁ guring computer’s IP must be

changed to the same range to

continue conﬁ guration. If the

LAN IP is changed, restart the

AirStation. (Section 4.4.10). If

the IP address is changed, then the DHCP scope must be changed to match.

DHCP Server Function - Allows administrator to enable/disable the DHCP server function for the

AirStation LAN side. Select Use to enable and Do not use to disable the function. Once Use is

selected, the assigned IP address range can be speciﬁ ed. Enter the starting LAN IP address and

total number of computers the DHCP server can accomidate.

■ Note: If there is another DHCP server on the network, one either must be disabled or the IP

range must be changed to avoid conﬂ icts derived from overlapping DHCP scopes.

normally as well.

Audio/Video Playback*: To play audio or video ﬁles through shared ﬁles

just double click on the audio or video ﬁle you would like to play or select

multiple ﬁles and create a playlist.

* Streaming audio or video over the internet requires an internet connection sufﬁcient 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 stream-

ing audio and most video ﬁles.

The Shared Files icon on the Network Service List gives you access to a PC or network

device’s shared ﬁles 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 conﬁguration. Please consult

your Windows documentation to learn more about setting up File and Printer Sharing.

NOTE: It may take a few moments for

the Shared Files folder to open after you

Troubleshooting

Troubleshooting WDS (Step-by-Step Instructions)

The most common issue with WDS installations is using the wrong MAC address. The proper MAC Ad-

dress for the access points is the ‘Wireless MAC Address’. The best place to document this is under the

‘System Information’ section of the conﬁguration 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 satisﬁed, then WDS can-

not 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 ﬁrst access point in the wireless bridge (this should be the DHCP server enabled ac-

cess 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 ac-

cess 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 conﬁguration 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 ﬁrst 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 ﬁrst 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 ﬁrst 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 ﬁnished.

ﬁeld 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 ﬁrst access point (which was recorded on Step 21) into the

ﬁeld 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’ ﬁeld 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-

ﬁguration on the network, then please contact your local agency described in Quick Setup Guide.
