Extremely erratic (and unusable) in client bridge mode

    After trying tomato with no success at all, I installed dd-wrt V23SP2 on my WRT54GL and set it up in client bridge mode.

    Primary router: speedtouch 585,
    Secondary router: WRT54GL, with gateway and DNS set to address above

    • I could connect to the primary router and I could ping the router and external addresses. I could even visit www.google.com but loading the page took about 1.5 minutes. That was yesterday.
    • Signal quality is quite low 40-50% although the two routers are standing next to each other. Other devices such as laptop see the primary router as 100% signal strength.
    • Today, for about a minute or 3, internet connectivity on the computer connected to the secondary router was fast (although signal quality was still low). But this went away by itself and for a while I could not ping even the primary router.

    What can be the issue here? Does DD-WRT / WRT54GL not play well with the speedtouch? Could there be a misconfiguration?

    • I used V23SP2 instead of V24 because I was worried about DHCP issues that may be present in V24.
    • Security is WPA pre-shared key.

    Please help.

    On my Fonera, client bridge mode never really worked well for me, either, until I tried V24-SP1 build from late July of 2008. With that version, client bridge has been rock solid!

    My only complaint was that, in client bridge mode, DD-WRT passes on that device's MAC address to the main network AP/router, instead of the MAC of the device connected to it, but I'd read that this had been fixed in newer builds of DD-WRT.

    So last night I tried an eko-BrainSlayer V24-preSP2 build from February of this year, and, while it did fix the MAC address issue, it's gone back to really spotty/finnicky wireless connection in client bridge mode.

    Just to follow up on this, I installed the newest eko-BrainSlayer V24-preSP2 build 260309 (March 26, 2009), and it works like a charm!

    Client Bridge mode appears to work perfectly, as it did on my old July 2008 build, with the added benefit of the correct MAC address being passed to my main router. Also tested adding a virtual Wi-Fi access point to the Fonera while in Client Bridge mode, connected to that, still worked great!
