WDS Connections:
Add Entry Button
Add an entry to the WDS Connections table. This adds a virtual station to the
device.
Delete Entry Button
Delete the currently selected entry in the WDS Connections table. To select a row,
click anywhere in the row with the mouse, to highlight the entire row.
Connection Mode
Specify the connection mode for this link.
AP (Downlink) configures the connection as a virtual Access Point.
Sta (Uplink) configures the connection as a virtual Station/Cient.
SSID
AP Mode: Specify the SSID that this virtual access point will use. Stations
connecting to this virtual access point use this SSID.
Sta Mode: Specify the SSID that this virtual station will use when connecting to
other access points.
Encryption
Select the required Encryption (if any) for this WDS link.
Encryption Key
Enter the Encryption key (for WEP encryption) or the passphrase (for WPA
encryption). For WEP encryption, the encryption key is set as WEP Key 1. For Sta
Mode, this must match WEP Key 1 on the Access point this virtual client will
connect to. For AP mode, clients must configure their WEP Key 1 to the same value
as this key and select the Default WEP Key to be WEP Key 1.
There are many different ways to setup wireless networks; often it depends on the devices you wish to connect and the
existing network topology.
The following pages show some examples of how to connect devices into different types of systems.
Example 1 Extending range using WDS
Figure 38 - Extending Range
One of the most common uses for WDS is to extend the range of the wireless network using repeaters. The diagram in
Figure 38 above illustrates a simple example where the four Access Points are all at fixed locations (each of the Access
Points could, of course, have one or more client/stations connected). Since the locations are fixed, there is no chance of
network loops so we can avoid the overhead of using the Bridge Spanning Tree protocol by configuring fixed WDS links
to ensure that each Access Point will only connect to the next Access Point in the chain. Any number of additional
intermediate repeaters could be added to the chain in a similar way.
The WDS configuration is accessed by selecting the
Repeaters
link on the configuration web page. Configuration for Site
A is shown above in Figure 39. Site A is configured with a virtual Client that will connect to the Access Point at Site B
