Tomato (USB) and WDS

    I easily made two WRT54GL v1.1 with TomatoUSB K24NoUSBStd-build52 work in WDS mode: one as router, connected to the Internet, the other as wireless repeater.
    The setup was outlined in the Tomato FAQ (
    I set wireless security to WPA2 with AES, even that works flawless.
    One thing that seems to disturb things are wireless clients (in this case IPods that are carried around the house) that are on the edge of one or the other WRT54GL, with either one having the strongest signal. The IPods at some moment kept switching from one to the other WRT54GL, slowing down the whole wireless network, including the fixed computers in the house.
    The solution may be to give the two WRT54GL their individual SSID and manual select the accesspoint with the strongest signal.
    Are different SSID supported in this WDS setup?

    Does the second router need to supply any wireless clients or is it just a "bridge" to a desktop?

    The second one (router used as accesspoint) will be used for wireless clients, it will really be used as wireless-repeater.
    I know that with different SSID's, you need to manually select the required accesspoint, which is ok in this case.
    I will give it a try soon anyway, was just curious if someone would know ahead if this is supported.

    I feel that u should just configure the 2nd router as a WDS-only router and not have your wireless clients connect to it. Only let the 1st router connect to your wireless clients.

    Sounds like he's using the second one ONLY for wireless clients.

    I don't think there are any tomato mods that will support a VAP(virtual access point). DD-WRT will, though.
    Assuming your house is big enough that one router isn't enough, you could load DD-WRT on the second router and place it in a central location of your house. Basically, you put the 2nd router in repeater mode, it will pick up the SSID of the main router, then create a VAP (new SSID) that all your wireless clients can connect to.

    ...maybe that's what you're looking for...

    I see.

    But if the wireless clients are able to detect the first router, then why not use that as the Access Point, since they will not get halved performance with the WDS relay.

    If the wireless clients are only able to detect the second router, then ok, keep that as the Access Point.

    WDS with WPA2 and AES doesnt seems to like different SSID's.
    Cannot get it to work that way, I may keep trying a bit later on.

    For Kiwi8: the router is at the first floor, clients on the third floor get a weak signal. I was hoping to use WDS with different SSID's to be able to manual select either the router or repeater (to avoid mobile devices hop between the accesspoints, as mentioned in the first post).

    The obvious solution is to put the router on the second floor, any reason not to?

    WDS seems to be a bit troublesome. Now it doesnt even get to work with the "standard" settings, it did went to work with WDS set to Automatic (instead of "Link with" and specify the other router MAC address). After moving the repeater to its destination on the first floor, the routers did not manage to find each other.
    Reverted the first router (the one connected to the Internet) back to orginal settings without WDS and stored the second router back on the shelf, no WDS for now.
    I can imagine that I need to give both routers a fresh start (maybe even a 30-30-30 reset) and start setting up WDS right from scratch (for another rainy weekend).

    Okay, i managed to somehow get WDS up again, with TomatoUSB build 52 and wireless clients only:
    WRT54GL#1 with connection to the Internet.
    WRT54GL#2 as wireless repeater.

    Both set for:
    -Unique LAN Router IP Address
    -Access Point + WDS
    -Same SSID
    -Same Channel
    -WPA2 Personal
    -Same Shared Key
    -WDS Link With: [the other WRT54GL MAC address]

    Only WRT54GL#2, the repeater:
    -WAN: Disabled
    -Default Gateway: [WRT54GL#1 IP address]
    -Static DNS: [WRT54GL#1 IP address]
    -DHCP Server: unchecked

    To get the link working first WRT54GL#2 (the repeater) must be up, then powerup (or reboot) WRT54GL#1 (with the Internet connection).

    To configure WRT54GL#2 of course a wired client with fixed IP address is used, when the connection is up the wired client on WRT54GL#2 is able to reach WRT54GL#1, this can be used as first test to check if the connection is up.
    The indication of the WDS partner in the Device List is no garantee that the link is really up.

    Anyway, after a few minutes (10 to 20?) the WRT54GL#2 (the repeater) lost the connection, connected wireless clients lost the Internet connection.

    For now I conclude that WDS with above settings does not work reliable.
    Maybe it is related to WPA2 Personal with AES??

    I've had issues with WDS on my two GL routers with usb build 52. I've had to flash back to build 50.
    I've done this twice. Give it a try...maybe it's not just me.

    Thanks for the feedback.
    I doubt that I will revert back to build 50 to just test WDS, maybe another lazy rainy Sunday when the family does not need Internet ;-)
