Buffalo WHR-G54S User Manual

Your AirStation’s WDS bridging capability allows you to extend the size of your wireless network by adding additional
AirStations, all connected wirelessly.

In this simple example, we’ll connect two AirStations in a wireless bridge. You may use these same steps to add
additional bridges for greater coverage.*

For easiest confi guration, we recommend confi guring all components in close proximity before deploying them to their
fi nal positions. Wired connections make initial confi guration even simpler.

The fi rst AirStation will be the router that receives the internet connection. On the
bottom of the AirStation, make sure that the switch is set to “AUTO”. If desired, you
may connect the Ethernet cable from your cable or DSL modem to its WAN port now,
though this is not necessary for confi guration. Power on the fi rst AirStation.

The second AirStation will be confi gured as a repeater/bridge. Make sure that its
switch is set to “BRI”. Use a RJ-45 cat5 Ethernet cable to connect LAN ports of the two
AirStations. Power up the second AirStation. Connect a PC’s Ethernet port to another
RJ-45 port on the main router (the fi rst AirStation). You will use this PC to confi gure
the settings of the AirStations.

Here’s the whole setup, ready for initial confi guration.

* Note: Each AirStation may be part of 6 different bridges. Remember that each layer of bridges takes about half your

total network speed, so avoid confi guring daisy-chains more than 4 bridges long. A star-pattern is always better, with a
central router serving multiple bridges.

Once the AirStations are powered on, you will want to make sure that they are in
factory default confi guration. On the bottom of each, hold down the “INIT” button
for three seconds. This will reset them to factory defaults. They will take 30-60
seconds to reboot afterwards.

Power on your PC. Make sure that it is confi gured to “obtain an IP address
automatically” from DHCP. Open a web browser and in the address fi eld, enter

192.168.11.1. This is the default IP address of your fi rst AirStation.

A login window will pop up. The default username is “root”. Leave the password
fi eld blank and click OK.

The Web-Based Confi guration Utility for your fi rst AirStation will open. Click on the
Advanced tab.

On the left side menu, click on Wireless Confi g, and then Basic.

Change the Wireless Channel from Auto to a channel. Make a note of the channel
that you’ve chosen, because all of your wireless devices will need to be confi gured
to use this same channel. Change Framebursting from 125 High Speed Mode to
Framebursting or Do not use (Framebursting is recommended if all your client devices
support it). Click Apply. Your AirStation will reboot in 30-60 seconds. Optional:
Note the SSID of this AirStation. By default, this value will be different for each
AirStation. For easy roaming, you may want to change the SSIDs of both AirStations
to a constant value.

On the left-side menu, click on Wireless Confi g, and then Repeater.

Repeater-Bridge (WDS) must be set to Enable. If it is not, change it to Enable in
the drop down menu and click Apply. After the AirStation reboots, the screen will
refresh. Click Edit Registered WDS Partners.

Under Add New WDS Partner Access Point, enter the wireless MAC address of the
second AirStation, the one that you want to form a bridge with. You can get this from
the bottom of the second AirStation. Enter it with each pair of digits separated by a
colon, e.g. 000D0B10F778 would be entered “00:0D:0B:10:F7:78”. Press New Partner
when done. The AirStation will reboot, and when the screen refreshes, the second
AirStation’s MAC address will be listed under Bridgeable Access Points.

Now, you need to configure the second AirStation with the MAC address of the first
one. In your browser’s address field, enter “192.168.11.100”. This will take you into
the Web-Based Configuration Utility for the second AirStation.

Once again, the username is “root” and the password is blank.

In the Web-Based Configuration Utility, click on the
Config, and choose Basic. Change the wireless channel to match the one you
set for the first AirStation. Change Framebursting from 125 High Speed Mode to
Framebursting or Do not use (whichever you chose for the first AirStation). For easy
roaming, you may change the SSID to match the current SSID setting of the other
AirStation. Click Apply. Your AirStation will reboot in 30-60 seconds.

Now, under Wireless Config, choose Repeater.

Confirm that

Partners.

Repeater-Bridge (WDS) is set to Enable. Click Edit Registered WDS

Advanced tab, select Wireless

Under Add New WDS Partner Access Point, enter the wireless MAC address of
the first AirStation (available from the bottom of the first AirStation), with each
pair of digits separated by a colon, e.g. MAC:000D0B10F779 would be entered
00:0D:0B:10:F7:79. Click New Partner when done. The AirStation will reboot, and
when the screen refreshes, the first AirStation’s MAC address will be listed under
Bridgeable Access Points.

The two AirStations are now linked by a wireless bridge. Unplug all the network cables and test the bridge by logging
into each of the access points with a wireless client. You should be able to connect to either of the access points from
Windows Wireless Network connection, getting an IP address assigned to your client with no error messages. You should
also be able to log into both of their Web-Based Configuration Utilities by entering their IP addresses into a web browser
(192.168.11.1 for the main access point; 192.168.11.100 for the bridged access point). If the first AirStation is connected
to the internet, you should be able to connect to the second AirStation and surf the web.

Once you can connect to each of your access points, you should configure WEP
encryption. Without WEP, anyone within range of your access points can easily
connect to your network. From within the second AirStation’s Web-Based
Configuration Utility (192.168.11.100), click on Advanced, then Wireless Config,
then Security. Note that you must set up WEP on the bridge (second AirStation)
first, before configuring it on the main router (first AirStation), or you will have to
reconnect the network cables to finish configuration.

Change wireless encryption from “no encryption” to “WEP”. Note that TKIP and AES encryption schemes will not work
with WDS; you must use WEP for encryption. WEP keys may be any of 4 different types; choose one of the following types
from the drop-down “WEP Encryption Key” box:

Character Input - 13 characters (ASCII WEP128 104 bit, key should contain 13 alphanumeric characters a-z, A-Z, 0-9)

Character Input - 5 characters (ASCII WEP64 40 bit, key should contain 5 alphanumeric characters a-z, A-Z, 0-9)

Hexadecimal Input - 26 digits (Hex WEP128 104 bit, key should contain 26 characters A-F, 0-9)

Hexadecimal Input - 10 digits (Hex WEP64 40 bit, key should contain 10 characters A-F, 0-9)

Enter at least one encryption key in the first encryption key space. The key should match the format of the chosen WEP
encryption type. Additional keys may be entered in boxes 2, 3, and 4.

Click Apply when finished!

After configuring the bridge (the second AirStation) for WEP, log into the first AirStation’s Web-Based Configuration Utility
(192.168.11.1) and make exactly the same changes to the WEP settings. All WEP configuration settings must be exactly
the same, or the AirStations will not be able to communicate.

Each wireless client that will connect to the AirStations must also be configured with the exact same WEP encryption
key type and encryption key. Consult your wireless client’s documentation for more information on configuring its WEP
settings.

Troubleshooting:

Most problems with setting up WDS are caused by incorrectly entering the MAC addresses into each AirStation’s Web­Based Configuration Utility. If you’re having problems, check the MAC address settings in both AirStations’s Web-Based
Configuration Utilities. Each Airstation should be configured to be in a bridge with the other’s wireless MAC address.

Confirm that all bridges are set to the same wireless channel.

Check the Packet Log (Advanced/Diagnostic/Packet Info) in each AirStation’s Web-Based
Configuration Utility to confirm communication between them (screenshot to right). The
“WDS” entries should show packets both sent and received. In this example, the packet
log shows packets sent but not received, so the next troubleshooting step would be to
check the other AirStation’s settings and packet log for more clues.

If you cannot access the AirStations wirelessly, reconnect the Ethernet cables as shown
on page 1 of this document to easily access the AirStations’s Web-Based Configuration
Utilities.
