Help with getting WDS setup to work better.

    When I was living with my brother I setup a WDS network with his WRT54G v1.1 and my WRT54GL v1.1 and it was rock solid. No issues. Both were running Victek's Tomato Mod. When I moved I bought a Asus RT-N16 and installed Teddybear's Tomato Mods (MIPSR2 fw) on it and the Linksys WRT54GL (MIPSR1 fw). I seem to have issues getting them to stay connected. I've tried changing settings and not much has helped. I have the RT-N16 running in B/G mode as I don't have any Wireless N Devices yet. This seemed to help a little. The speeds between the routers seems slower. Would setting them both to G only help any. I think the only real solution would be to buy a 2nd RT-N16 and sell the WRT54GL. But I thought I would check if anything I can do with the settings to get them to talk to each other better until I find the money to get a 2nd router. Also would using a different fw work better. Like Victek's version or even dd-wrt. Thanks for any help.

    Try builds 54 (with newer wireless driver) and 52, and compare which one works better for you.

    In my tests, WDS with RT-N16 was unstable in all previous builds using the older driver, but works very good with build 54. Granted, I only tested it with various Asus models - WRT54 might be totally different...

    I just updated to build 54 today on both routers actually. Like I said I think its because I'm using 2 different brands of routers that I'm having issues. I just wonder what other things I can try until I get a 2nd asus router. Like would running them both G only mode rather than b/g. I know if I leave the asus in b/g/n mode it seems to make things worse. I also blocked all wifi devices from being able to connect to the 2nd linksys router this helped improve speeds a bit. I also noticed with the MIPSR1 fw on the linksys the transmit power defaults to 42 and the MIPSR2 fw on the asus defaults to 17. Is this normal? Also one of the issues I run into with WDS is that when I check the Device List on both routers show that is it seeing the other each others router but it not transmitting to each other. I can then power cycle the linksys all I want and it still won't connect. I then power cycle the asus and then they both finally start talking to each other.

    I have found that WDS connections get very problematic when different versions of the wireless driver are used at either end. I just could not get ND software to connect with non-ND software.

    It is also the case that the link showing up in the device list is completely independent of the link actually being set up. The fact that the link shows up in the device list is simply due to it being configured, not to it working. Power on just one side of the connection and see for yourself.

    I also found that getting WDS links (when they do work) to initialize was very finicky. Devices had to be turned on in a certain order and with certain timing for it to initialize.

    Finally, you might want to check out this blog entry that talks about WDS links breaking down after a period of time.

    I'm thinking that their conclusion of using WET rather than WDS is the way to go. While WDS was designed for point-to-point links and has no additional bandwidth losses over WET mode (personal hot-button), it's just too unstable for reliable use.
