HOWTO : Wired router connected to wireless router with WDS

I have two identical TP-Link TL-WR1043ND routers and they are both flashed with DD-WRT (build 20548). I connect these two routers together with a wired router and the tutorial is here. The new setup is wired router to wireless router and then wireless router. The two wireless routers are act as WDS (Wireless Distribution System). The firmware of DD-WRT can be download here.

At the tab of "WDS" on each router, make sure they are set to "LAN" and set to other's MAC address. Select "Lazy WDS" for both routers and "Apply Settings".

Make sure all the wireless setting on the both routers are identical, such as channel and etc. Also make sure the security wireless setting are disabled on both routers at the moment. We will enable it later.

The wireless router that is connected to the wired router is A and the other wireless is named B. Make sure to disable the firewall at the router B which is not the one connected to the wired router.

On the router B (which is not connected to the wired router), set the Internet "Connection Type" to "Disabled". The "DHCP Type" is set to ""DHCP Forwarder". The "Local IP Address" is set to the same network (subnet) of the wired router but in a different IP address. The "Gateway" is set to the address of the router A that connected to the wired router. The "DHCP Server" is set to the address of wired router.

For example, wired router IP address is 192.168.0.1 and it is act as DHCP server. Router A address is 192.168.0.80 and the settings is same as the captioned link at the beginning of this article. Router B address is 192.168.0.90 and the gateway is set to 192.168.0.80 and the DHCP server address is set to 192.168.0.1.

Enable the wireless security setting on router B and then A. They should be identical too. Now, you can connect to the internet properly without problem.

That's all! See you.

HOWTO : Wireless Router connects to Wired Router

*** This tutorial is written on July 16, 2007 by me. I repost it here for reference. The origianl tutorial is here. ***

I have a wired and a wireless routers. I connect them together to make them looking as one router. Then, I can access all the computers within the same intranet.

Router A (connect to the internet)

Step 1 :

I assigned the wired router to be router A which is connected to the internet directly. I did nothing on the Router A. The LAN IP is 192.168.0.1.

Router B (connect to the Router A)

Step 2 :

I assigned the wireless router to be Router B and I should change the settings of it.

WAN -
Set the WAN IP to be static 192.168.111.2, subnet mask is 255.255.255.0 and gateway is 192.168.111.1, no matter your Router B is wired or wireless. For me, Router B is a wireless. (You can change the WAN IP and gateway to meet your requirement, here is only an example)

LAN :
Disabled DHCP and set the LAN IP to 192.168.0.200, subnet mask is 255.255.255.0, no matter your Router B is wired or wireless. (You can change the LAN IP to meet your requirement, here is only an example)

Step 3 :

Connect Router A and Router B via a cable on LAN ports only. WAN port will not be used at the Router B. Connect Router A to the internet as normal. Now, you can access Router A by 192.168.0.1 and Router B by 192.168.0.200 via your browser. Any computer or laptop will be assigned an IP of 192.168.0.XXX.

That’s all! See you.
