About WDS Problem - 2 AP's signal work as 1 AP's

    How to make it as the situation is 2 AP signal as 1 AP signal , because when i using the WDS mode in my WRT54G(dd-wrt),i found 2 different SSID on my survey list(even they are the same SSID name).Although , no problem if i connect to either one , they all go back to the main's router network.
    But in this situation , i will get a different signal in different places , if i want to get a better signal , i need to connect to another SSID's AP.

    Can i use the signal one for all?
    I mean , one SSID include those 2 routers signal , so it will like a wireless signal booster , than i don't have to change the SSID to get different signal.
    Any ideas to make it under WDS mode or whtever?


    The solution i want is below:

    Main Router(WRT54G)--->WDS to--->Secondary router(WRT54G)--->Combine the wireless signal together without changing the SSID in different place.

    :confused: :confused: :confused:

    With WDS you can use the same SSID...

    no ,which i saw is the same SSID , but when i try to survey again , i saw the different Signal of the same SSID,but i can still use it.The situation is when i connect to router 2 SSID , i can't get roam to router 1 SSID automatically when i needed, so i can't use the best signal ever.

    Is it i have to put different Channels but Same SSID on two of the router?

    Roaming is not WDS !

    Roaming -> the APs are wired, different channel, same SSID

    WDS -> the APs are not wired, same channel, different or same SSID

    thanks for your reply.

    My undertand is ,that's mean i can't use the things like range expander under my WRT54G , is it?
    Otherwise i need to wired between the 2 AP's than i get the things like range expender.....
    is that your meaning?

    Another question is later dd-wrt will release v24 , they will have WDS-Repeater mode.Is that meet my solution?

    I just want the signal cover all my house without changing the SSID by myself manually.

    In all cases, you don't need to change manually !
    On your PC client, you have only to register the wireless networks you use (SSID, encryption, etc.) and automatically when it starts (or moves), it uses the best one.

    The adaptator has a parameter to define the switching signal threshold (-70dBm)...

    hello every body i
    need some help wich Router and Access point have the WDS option can me tell any body Faisal

    also there is one more thing some body know the lino wave?

    To Hispeed:

    There still a problem while letting the wireless client adaptor to do the "auto choosing".There still a connection drop in this case , it might change the ip if in some case. Also ,some application needs to be keep continue ping to the network.Any method to prevent the lose of connection?

    Is it WDS a wrong idea when using my solution?

    The major inconvenient with WDS is the troughput performance divided by 2 !

    Why don't you put fixed addresses ?

    I dont think the WRT54G units supports true roaming, where client information is passed between APs for seamless transitions....

    I think it is able to do it, but not with any linksys or current 3rd party firmwares....

    This is not a true roaming but very similar.
    When one AP stops (or the client goes to far away), the client is automatically reconnected to the other AP...

    Letterboy, your WDS will work, but it's not the ideal solution. I take it you don't want to-, or cannot-, wire your 2 APs together for a true roaming solution?

    If so, you can still use your WDS, but be aware of the following:

    It sounds like you have the DHCP server running on both APs, i.e. 2 DHCP servers, which is why your client changes IP address, and creates a delay. Enable only ONE of your DHCP servers. This will then allow the switch from one AP to the next AP to be much smoother. You may or may not have to set the "other" AP to be a DHCP relay - I'm not sure about that.

    gcore, the roaming is just about seamless among wired WRT54s. If you "ping -t Some_IP" while on AP #1, and then walk/move so you get to better range for AP #2, I found that you only miss 1 or maybe 2 pings. I also think that the roaming is more a function of the card/adapter/driver and WZC (or whatever utility) than it is of the AP, as the decision is made by the client side stuff. I'm speculating here..., but that's my humble opinion.

    Linksys WRT54G using DD-WRT 3rd party firmware.

    Use the same channel, security, and SSID.

    I have 3 routers (a v1.1, v2.0 and a v3.1), all flashed with the same firmware.

    Router 1 is the gateway (only this one has DHCP enabled). Under the WDS config it has the MAC of Router2 and Router 3 entered. Router2 and Router3 just have the MAC address of Router1.

    For linear range expansion, I could configure Router1 with MAC of Router 2, Router2 with MAC of Router2 & Router3, and Router3 with MAC of Router2.

    This all works great.

    So , i think the solution i want is to get roaming instead of WDS.
    The second router i did not set the DHCP server , only enabled on the main router.
    As "Hispeed" said , this is not a true roaming , but similar ,what i really want is a true roaming that i won't have a connection signal drops between each AP's.
    I understand now , thx all.
