WDS

WDS_Link #x - This is only to identify your WDS link. The wds0.2 virtual interface is WDS Link #1, the wds0.3 virtual interface is WDS Link #2 and so on...
Mac_Address - This is where you enter the MAC address of the router's wireless interface that you are connecting to. This can be found either through the WEB interface (admin --> STATUS --> Wireless) or by incrementing the last digit of the MAC which is located bottom of the router by 2 (in HEX).
IP_Address - This setting is to configure the ip address for the WDS interface itself. It is recommended to use a different subnet than your local network.
Subnet_Mask - This is the WDS interface netmask for the above ip configuration. The value should be 255.255.255.252, other values have caused issues with WDS setup. In particular, do not use the same subnet mask as your local network if you are putting your WDS IP addresses in a subset of the subnet of your local network (i.e. If your LAN is network 10.0.0.x/mask 255.255.255.0 don't use 10.0.0.15, 10.0.0.16, and mask 255.255.255.0 for WDS. 10.0.0.15, 10.0.0.16 with mask 255.255.255.252 appeared to work in preliminary testing. If you follow the recommendation not to put your WDS and local network within the same subnet, then this note shouldn't even apply to you.)
Default_Gateway - The Default gateway is the machine that you want as the gateway between the local network (LAN) and the other networks (WAN). This is the default route when packets that are not destined for the local network will be sent down for further processing and delivery. It may be left as 0.0.0.0 ('blank) for basic WDS setups.

WDS Quick Setup Guide

Set up the router's basic settings such as IP address such that they do not conflict with each other. On both routers set the CHANNEL and SECURITY to the same settings (Note that only WEP or no security at all can be used here). The SSID does not have to be the same on both routers.
Disable the firewall from the security --> firewall tab as well, and uncheck block WAN requests.
Now you are ready to set up the WDS link. We recommend to use different IP addresses than your local network ip range (for example ip range 192.168.1.0/24 means ip: 192.168.1.x netmask: 255.255.255.0 ; WDS range 10.0.1.1/30 means ip:10.0.1.{1,2} netmask: 255.255.255.252 ).
Now you should type in the other end's MAC address which can be found at the admin --> STATUS --> Wireless tab on the web interface. If both sides are set up properly the WDS link should be established. However, you may need to reboot each router. Now telnet or ssh into each router (assuming you have enabled those features) and type "brctl addif br0 wds0.2" (or if it is not the first wds link then replace wds0.2 with wds0.x, where x means the wds interface + 1).
If you did not enable telnet or ssh, go to the admin --> management interface, hit run and in the popup windows type the above command.

Note: With Satori pre1 and pre3(original), if you make any configuration change on or reboot the router you will need to re-enter the command 'brctl addif br0 wds0.2' in order to get the WDS working again. Apparantly this requirement is eliminated by using OSPF, or by using later pre3.x versions. WDS/OSPF References:

Q. Does WDS have a lot of overhead and reduce bandwidth?
A. Sveasoft wrote:
WDS will halve the throughput as it needs to double transmit the data. 802.11b/g are half duplex which means only one side is transmitting at a time. WDS means double transmissions must take place and effectively halves the bandwidth.

This should be true for wireless client PCs connected wirelessly to the second WRT54G. Client PCs connected directly via wired ethernet to the second WRT54G shouldn't see the bandwidth cut in half.

Q. Can I run my WDS links on different subnets in Satori pre3.3?
A. Yes...via the shell in pre3.3, probably via the WDS tab in pre3.4 or so:

If you want separate subnets in Satori-pre3.3 for your WDS links please add them in the rc_startup script.

Code:
wl wds none
wl wds [MAC 1] [MAC 2] (etc)
ip addr [IP 1]/[netmask] dev wds0.2
ip addr [IP 2]/[netmask] dev wds0.3
        ... etc ...

You will still be able to see the WDS strength in the web interface.

You may also want to add "wl wds none" in your rc_shutdown script.
