Bug with WDS and WPA

    i think i found a bug,

    im currently using 2 WRT54GS, one in AP+WDS and the other in WDS mode,

    When using WPA Personal security mode, if i use WDS Link with ...... and set the wireless mac on each router, my clients lose connectivity around every 1 minute and then they reconnect like every 5 minutes,
    now if i set WDS to automatic/lazy mode my clients works fine.

    im not sure if its a bug or not but i though of posting it in case anyone else is having this problem.

    my setup:

    router 1
    WAN type dhcp
    ip 192.168.1.1
    dhcp server disabled
    wireless mode Access point + WDS
    Security WPA Personal
    WDS Automatic/Lazy

    router 2
    WAN type Disabled
    ip 192.168.1.69
    dhcp server disabled
    wireless mode WDS
    Security WPA Personal
    WDS Automatic/Lazy

    put both routers in the AP + WDS mode
    don't use lazy, specify the mac address to connect to.
    you might want to add mac filters (don't forget to add the mac address of the routers to the list)

    telnet (or ssh) to both routers and enter the following command.

    nas4not lan wds0.2 up supplicant aes psk password ssid

    and try again

    Is it necessary to telnet and enter the command to both routers? Or can WDS be set-up strictly using the Tomato GUI - ie, is this something Jon needs to be aware of?

    I had problems with WDS and WPA before I used the nas4not command, so may be we should check with Jon.

    It is not necessary to telnet in... I placed the command in the Start-up script and it works fine.

    But it does appear to have weaker signal in WDS+WPA than in WDS+WEP

    I have discussed the use of the nas4not command in the startup script with Jon. His explaination to me said that placing this command in the startup was incorrect and would probably fail (with out a proper delay). I removed the command, rebooted my router and it has been working without it ever since (approx. 11 hours)

    I do remember from when I ran Thibor, that it was always recommended after configuring WDS that the router should be rebooted to establish the wds connection (which is a step with Tomato that I had forfotten)

    Jon suggeste running ifconig and make sure the wds0.49153 was listed. (this is the updated version of the wds0.2 that I was playing with.

    without using nas4not in my startup I see the wds connection listed on both routers.

    i still cannot use WDS with WPA using LINK with... even after running the command
    nas4not lan wds0.2 up supplicant aes psk password ssid

    its running fine using automatic/lazy mode.

    Do both routers have the same ssid? Verify that you have entered the password/passkey correctly and that the ssid's are the same. make sure you have enter the mac of the other router in the mac filter if you have that enabled. and make sure you are running 1.02

    yes i have triple checked everything, same ssid, same password, tomato 1.02, wireless mac of routers and clients are set on my filters,
    weird thing is that it will work on WDS link with, but only for a really short time (around 1 to 2 minutes) then all my clients disconnect at the same time.

    im going to keep them in automatic/lazy mode for now.

    here's my setup

    just make sure wds is using the "wireless" mac not the router mac (there is a difference)
