Basic WDS configuration

The Wireless Distribution System (WDS) allows you to bridge wireless traffic between access points. It is actually somewhat like connecting a "wireless cable" between two Edges Edges/Safe@office /Safe@office, over which traffic can easily pass between them. Configuring a WDS link is similar imilar to creating a VLAN.

Prerequisite At least 2 Edge/Safe@office wireless/wirelessDSL devices If we’ll use Safe@Office we need ““POWER PACK” add-on on all devices that we want to configure WDS on . On all devices that participate in the WDS network make sure Wlan is enabled. Under NetworkMy Network WLAN WLAN change “Channel” from “automatic” to Static. Reference for terms in this document: Master: The device that through it internet connection is provided provided. Slave: The “repeater”, the device that connect to the Master via WDS connection.

Master WDS : Under NetworkMy My Network we'll click the "Add Network" button; we'll choose a name and set the type to "Wireless reless Distribution System". We’ll add “Peer WLAN MAC Address” of the slave device (we’ll find the Mac address under “Reports”  “My Computer” “WLAN”). WDS supports WEP encryption or none between the two or more devices.

Slave configuration (Repeater WDS ) :

Add Bridge :

Under NetworkMy My Network we'll click the “Add Bridge” . The configuration needs to be: Type “Network Name”. (Any name) In the “Firewall between Members” field choose “Enabled or disabled”, ”, this feature will enable you to decide whether you want to activate a firewall policy between the bridge members. (ie:LAN,DMZ,WLAN) In the “IP Address” field we’ll need to type the same subnet we type typed at the Master device. device (ex: 192.168.50.2/255.255.255.0)

Add WDS Network :

Under NetworkMy My Network click the "Add Network" button, we'll choose the same name that we gave to the Master WDS network and set the type to "Wireless Distribution System". We’ll add “Peer WLAN MAC Address” of the Master edge. In “Wireless Settings” area “Security” Security” configure the exact configuration that was configured at the Master device. add the WDS to the bridge networkk under “assign to bridge to allow for internet traffic to reach the wireless clients through the WDS link.

Checking connection between Master and Slave: Under “Reports”  “My Computer Computers” we’ll see “WDS Peer” and the Mac address of the Master or the Slave. We’ll need to see that we have Signal between the peers.

Adding Network WAN to Bridge: Under Network  Internet Primary Primary, under “Connection Type” choose “Bridged”. In the “Default Gateway “field enter the ip address of the Master device WDS network and the same ip address at “Primary DNS Server”. (Ie: 192.168.50.1)

Wireless reless roaming between two Edge/Safe@office devices

The simplest WDS setup is needed when you want to deliver WLAN connectivity over an area, larger than a single Edge/Safe@office can support, and you do not want to physicall physically y connect two Edge/safe@office devices with Ethernet cables. In this setup each of the boxes will have a wireless network (WLAN or any other VAP) bridged to a WDS lin link. k. The WDS will be configured with no antispoofing.. This way when one the WAN connections are down, traffic can still reach the internet through the WDS and the WAN connection of the other Edge Edge/safe@office.. Of course, this setup does not no have to only include ude two Edge/Safe@office devices , but rather can be enlarged by connecting other Edge/Safe@office devices with WDS.

WDS rings and WDS mesh

If we want to cover a large area with a large number of appliances, we would like to have a number of internet connections, both for load balancing between the stations and for redundancy, and we would like to add as much redundancy as possible so that if a single link fails, there will still be other links through other Edges. This would of course require not only WDS links, but also using STP over the WDS links. Edge/Safe@office devices support up to 4 APs with 3 VAPs and the main wireless network and up to a total of 8 wireless networks including the VAPs and the WDS links. This means that with 2 VAPs, Edges still support 6 WDS links.
