First of all, I currently have a Belkin ADSL2+ wireless router. I'm trying to setup a WDS connection on RB493G. Therefore, my far away PCs can access Internet through RB493G wired or wirelessly. Here is a simple topology diagram.



I asked the same question to MikroTik support. They gave me a pretty simply answer.

To make it work as repeater,
- Use mode=station-pseudobridge on the RB493G;
- add to bridge wlan interface and Ethernet interfaces;
That's all.
IP address/routes are needed for management only on RB493G.

I tried, but it still doesn't work. I replied and asked questions about WDS and DHCP relay. MikroTik support just ignores me.

In order to access the Internet, I have done some extra configuration on RB493G and manually config my PC with static IP. However, weird things happened. Some of my computers can access Internet while other computers with same configuration can't, so I decided to start over and ask questions here.

The thing is that I am able to establish a connection to Belkin router, but nothing else further. I can't get dhcp client to work on my wlan interface (BTW, I have R52Hn on my RB493G). I tried to work another way around so RB493G can bypass DHCP information by using DHCP relay. I failed again.

I will be very pleased if there is any hints or help. Thank you very much.

For WDS....

Does your Belkin support WDS??....your Wireless interface in your RB should be in mode=wds-slave and select the wds-mode and the bridge where the wds link will be working, you have to create a bridge add the wireless and ethernet interfaces to it, create a wds link (it can be created dinamically depending on the mode)...

now if you want to use the dhcp relay...you can read this

Thank you for reply.

No, I don't think my Belkin router supports WDS. I just wish there is a way to repeat wireless signel. In the worst case senareal scenario, I hope the ethernet interfaces can receive DHCP info from Belkin.

I have tried everything I can about this. I googled, asked mikrotik support, and tried everything I can think of on RB493G, but I just can't get it work. I found a post related to DHCP relay. However, I can not fully understand what they were talking about. As far as I know, DHCP relay would not work unless it has the first IP set on a certain interface. Any clues?
