Ch 3. Configuring WDS 
Wireless Distribution System (WDS) uses wireless media to communicate 
with the other devices, like the Ethernet does. This function allows one or 
more remote LANs connect with the local LAN. To do this, you must set 
these devices in the same channel and set MAC address of other devices 
you want to communicate with in the WDS AP List and then enable the 
WDS.  
When you decide to use the WDS to extend your WLAN, please refer the 
following instructions for configuration. 
z
  The bridging devices by WDS must use the same radio channel.   
z
  When the WDS function is enabled, all wireless stations can’t connect 
the device. 
z
  If your network topology has a loop, you need to enable the 802.1d 
Spanning Tree function. 
z
  You don’t need to add all MAC address of devices existed in your 
network to WDS AP List. WDS AP List only needs to specify the MAC 
address of devices you need to directly connect to. 
z
  The bandwidth of device is limited, to add more bridging devices will 
split the more bandwidth to every bridging device. 
WDS network topology 
In this section, we will demonstrate the WDS network topologies and WDS 
AP List configuration. You can setup the four kinds of network topologies: 
bus, star, ring and mesh. 
In this case, there are five devices with WDS enabled: WDS1, WDS2, 
WDS3, WDS4 and WDS5.
