the same as that used by the wireless AP/Router to which it is linked. Selecting
Auto Select enables the wireless AP/Router to automatically select an unoccupied
radio channel.
Wireless Distribution System (WDS)
The WLAN1 radio interface can be configured to operate in a mode that allows it to
forward traffic directly to other access point units. To set up links between access
point units, you must configure the Wireless Distribution System (WDS) forwarding
table by specifying the wireless MAC address of all units to which you want to
forward traffic.
Traffic forwarded to WDS links is automatically converted to 802.11 four-address
format frame. This uses the MAC addresses of the station and that of the AP
connected to it on the transmitting LAN, and the MAC addresses of the AP
functioning as a wireless repeater/bridge and that of the station connected to it on a
neighboring LAN in the 802.11 frame header. Ethernet traffic follows a three-address
format that is reconstructed for WDS transmission. The wireless AP/Router will
reconstruct the frame format upon receival and transmission using the criteria of the
receiving and forwarding port location and whether it is Ethernet or wireless in type.
Note: The wireless AP/Router does not support the spanning tree algorithm. WDS links
should be configured appropriately to avoid causing loops on the network.
Up to four WDS links can be specified for each unit in the WDS network.
The WDS link can be configured in the following combinations:
1. All units are configured as Gateway Mode
2. Units can be configured as Gateway Mode and Bridge Mode combinations.
(ex: 2 units for Gateway Mode and 2 units for Bridge Mode)
3. All units are configured as Bridge Mode
When both units are set to Gateway Mode, be sure to check these settings:
• Be sure each unit is configured with a different LAN IP address.
• Be sure that only one unit has Internet access on its WAN port.
• Be sure the DHCP server is enabled only on one unit. If one unit is providing
Internet access, enable the DHCP server on that unit.
Note: WDS Settings only apply to WLAN1. WLAN2 is pre-configured to Bridge mode
unless WLAN1 is configured to act as a bridge, in which case WLAN2 is disabled.
