Help, Modem Keeps Restarting (WDS)

    Hello I have a setup that looks like this



    I have set the first router connected to the modem as an AP and the second router that is connected to it as an AP + WDS. I have DHCP disabled on the second router and both broadcast the same SSID ( with WPA TKIP Security ). I have set it to Automatic mode for WDS

    First of all , do I have these settings correct?
    Secondly when i have things setup this way, it seems like the modem cycles quite often and i can never get a constant stable connection. I am using tomato 1.23

    What is the modem and connection method to the first router, PPPoE ?

    PPPoE is dsl right? I am using a Cable Modem Internet Service. I have connected the Ethernet cable from the cable modem to the Internet/WAN port of the Router

    When I play games online. My connection would seem to stall, then reconnect with the server and this would happen frequently. It wouldn't disconnect completely with the server though.

    This also happens when i browse and use IM programs. Firefox would just suddenly stop loading pages and then MSN would drop, then everything would work after a few seconds. It seems like the modem is being reset, or loses connection with the router because the PC connection LED on the modem keeps blinking.

    After some tests, I tried unplugging the connection from first router A to B and I seem to have no more problems with internet on PC A ( see diagram in earlier post). So I think it could be the settings that are causing this.

    If you have the router's connected together with an ethernet cable (what ports did you use to connect them?), you shouldn't need WDS at all. And make sure you are broadcasting on different channels for each router.

    I believe i did lan port from router a to lan port in router b.

    I want to have one large area covered by one broadcasted SSID. Should i set them both to AP with same ssid and security key? how about DHCP on router b? Should that be on?

    Ill make sure they are on different channels

    I thought with WDS you don't wire them together like switches because they're already re-broadcasting everything over both routers wirelessly. Now, you can plug in devices into the LAN ports of each, but you I'm pretty sure you don't connect them with a patch cable.

    EDIT: Read the first paragraph here: http://www.dd-wrt.com/wiki/index.php/WDS

    I think you have the idea now.

    You should connect the two routers via LAN-port to LAN-port ethernet cable. Configure them both as Access point with the same SSID and encryption settings, but a different channel. Disable the DHCP server on the second router, and you're done (however, you'll want to manually assign LAN IP addresses on the same subnet to each of the routers). You'll have a large area covered by a single SSID, and clients will roam between the two as necessary.

    WDS is only useful in cases where you aren't able (or willing) to connect the two with a cable. In that case the WDS link acts as your connection, with all of the disadvantages that wireless brings. Since you're able to do it wired, that is a much better solution.

    Excellent suggestion.

    Sorry, could you clarify what you mean here? I already have set the addresses to both routers separately and Is this what you mean?

    Alright I've set it up and seems like my connection is stable for now. Thanks for the help!

    For channels I've chosen 6 for router a and 14 for router b

    I have another question about QoS settings or TCP vegas. I have quite a few devices that connect to my network, psp, ps3, 1 lenovo laptop, 2 desktops connected by ethernet, 3 iphones.

    I dl occasionally using Bittorent and Newsgroups, Should I look into those two settings for prioritizing bandwidth?

    Hmm i'm still having problems with this setup after using these settings, the router seems to stay on however i the modem keeps cycling. Any ideas ?? I'm on rogers cable in canada

    Seems to go away when i disconnect the second router from first.
