    I want to extend the wifi range and have a spare WRT54GS same as main router. Both running DD-WRT and have tried numerous times to get WDS working with no success. How else could I use them both to extend the range?

    study c language and create your own firmware is the hard way searching the net for a better firmware is the easy way

    Could use wds or make the 2nd router a client of the first. Could also get better antennae if you have the capability of removing the original antenna.

    where are you having issues in the setup?

    Routers seem to link together but once the second router has been disconnected from the wired link I am unable to access it via wifi so
    I can't see what it's doing any more! Should I be able to access it via wifi?

    Ok I gave it another try and am having some weird MAC problems - maybe I missed this the first time around!

    When I set it all up with MACs in each other, my 'second' router shows in the wireless status page that there is a WDS node on the correct MAC address of the main router. Now for the wierd one. On the 'main' router on the same wireless status page it shows a WDS node on the wireless MAC of the second router at 100% BUT it's also showing a client connected at 56% strength and that is also the second router but on a different MAC! 100% is the MAC
    00:16:BE:B4:1B:E5 which I've double checked is the wireless MAC of router 2, the 56% strength MAC is 00:16:BE:B4:1B:E4? Checking again and it looks like the 2nd router has the same MAC for both wired and wireless (E4).
    How can I change it and where is the one ending in E5 coming from? Was this a bad flash and can I reflash it again safely and hope the MAC's get sorted this time or is there a way to change the wireless MAC to E5?

    If you look at the page that comes up when you first go to the routers address there is 3 MAC addresses. LAN, WAN, and Wireless. To get the one you want to use click on wireless, then on the WDS tab and its listed at the top.

    also on the WDS page, make sure you have it listed as LAN, not Point to Point.

    Tried it all again tonight. Did a complete reset on router 2 and when it came back, the 3 MAC addresses were correct, each offset by one - E3, E4 and E5.
    Great so now let's set it up. Did everything for WDS BUT now when I go back to the sys-info page the wireless MAC has changed again to the same as the LAN MAC! Now totally baffled and it still won't work!

    Ok reset everything back to normal on router 2 and the MAC has gone back to what I expected? Does WDS change the wireless MAC on a client?

    Also on the SECOND router that connects to YOUR MAIN ROUTER make sure the connection type is set to disabled.

    So login to your second router then
    Setup > Basic Setup

    And change connection type to "Disabled"
    And save settings at the bottom.
    Let the router reboot.

    On the 2nd router ALSO
    Setup > Basic Setup

    Change the IP address to something other than
    I'd recommend changing it to because two network devices cannot have the same IP so you must set it something other than

    In the Gateway and DNS boxes change them to both
    Also Change the "DHCP Server" to "DHCP Forwarder"
    Then "Save Settings" at the bottom.

    Also be sure to double, triple check your MAC address in Wireless > WDS tab in both routers.
    Again make sure that the WDS type is set to LAN and NOT Point to Point.

    Be sure to try that and see how it goes. Post back your DETAILED results if you have a problem.

    EDIT - WDS does not cause a client's MAC address to change. The MAC address is embedded into the physical layer of the card and cannot be changed by normal means.

    Thanks for the help, I've done all of that except for the DNS Forwarder.

    Just tried it all again and still puzzled my those MACS Here is the sys-info
    from my main router
    Wireless MAC

    Which is what I expected and the 2nd router links up to the Wireless MAc.

    Now for router 2 (!)

    Wireless MAC

    Not what I expected as WAN and Wireless show the same! Go to WDS tab and it says the Wireless MAC is E5 which I thought it should be.

    Set up both MACs in each router and this is what happens -

    On router 2 I see

    Wireless Nodes
    Access Point
    MAC Address Signal Noise SNR Signal Quality
    00:18:39:E6:D1:37 -40 -93 53

    But on router 1, the main router I see this

    WDS Nodes
    MAC Address Description Signal Noise SNR Signal Quality
    00:16:B6:B4:1B:E5 Downstairs 0 -98 98

    but here's the odd one, I also see this

    Wireless Nodes
    MAC Address Signal Noise SNR Signal Quality
    00:18:DE:AC:6B:9A -81 -98 17
    00:16:B6:B4:1B:E4 -43 -98 55

    So it looks like router 2 is on the MAC ending in E4 not E5? So now I am really puzzled (again!)

    Changing the MAC to end in E4 on router 1 doesn't sort anything out either so anyone know what the heck is going on and what I'm doing wrong? Could this be a bad flash and should I try to flash router 2 again?

    OK I've reset everything and set it all up yet again. Both routers now show WDS nodes but the only way I can get it to work is to connect router 2 via a network cable!! Both on same channel and SSID and signal strength has gone up quite a bit but that's not really what I thought WDS was all about?
