    I flashed the DD-WRT v23 SP1 onto my WRT54GS v1.1, after a couple of years of using the Linksys firmware.

    After this change, the throughput in the local network has gone down for both the wireless and wired connections, as follows:

    - on wireless I used to get 2.6MiB/s, now I only get 1.3MiB/s, and only for relatively short periods of time. It's more frequent that I get 500-700 KiB/s, and after a few minutes of transfer all grinds to a halt. The connection isn't dropped, and other connections work well on the same interface. For instance, a previously open ssh connection works very well. So, I would guess that, somehow, packets get dropped and while they're requested all over again, the queue fills and nothing else gets through.

    - on the wire I used to get 7.5MiB/s, now I get 4.3MiB/s. This is stable.

    As far as I can tell, I reproduced the same settings I had when I was using the Linksys firmare.

    The router doesn't seem to be use too much of its processing power, as the load reaches 0.3 or lower.

    Obvious settings:
    - wireless: g-only, afterburner enabled, tx rate 54 Mb/s, frame burst enabled
    - firewall: block anonymous requests, filter IDENT port, IP max number of sockets 4096, socket timeout 10 s

    At this point I'm looking for other settings that would solve the issues with the throughput.

    Note: The primary reason to switch from the Linksys firmware was that WPA was hard to use: every few hours the laptop and the router would simply stop talking to each other, and all I could do was to turn off the network, wait for all sockets to be closed, then start it again.

    It's not entirely clear what caused this, but I would have to guess it was a bug of sorts in the Linksys firmware, since I don't get this with DD-WRT.

    Thanks for any help
