WRT54GL v1.1 + Tomato v1.28 + uTorrent 3.0 = no GUI access

    I have a problem which started recently:

    I am using a WRT54GL v1.1 with latest vanilla Tomato and uTorrent 3.0. It was working great till two weeks ago, when browsing became sluggish as soon as I started uTorrent (I am also using Cfosspeed on all connected clients). At the same time WRTGL54 wasn't accessible anymore.

    Because I haven't changed any settings, I reinstalled uTorrent as a precaution and deleted all settings. The browsing is normal now, but after a while my WRT54GL still isn't accessible any more. It does it's job though.

    Any ideas?

    When your router become slow do: "nvram show |grep entries" and look what NVRAM you have left.
    Maby you have run out of ram !?

    You should really upgrade to Shibby Tomato because vanilla is over 2 years old now and the latest Shibby works fine for the same thing you describe having a problem with.

    Don't forget to clear NVRAM after upgrading.

    # nvram show | grep entries
    469 entries, 12836 bytes used, 19932 bytes free.

    It's a WRT54GL with limited resources and memory. To remain stable with uTorrent and a lot of Torrent connections it is usually necessary to reduce the conntrack/netfilter timeout values. Most modern tomato firmwares have these reduced somewhat as a default when they are initially flashed. In my releases these timeout settings are vastly reduced so that the routers will rarely ever need any attention in that area. You don't need to change firmware though, just pay attention to the settings whatever version you are running.

    please give recommendation,
    my conntrack configuration:
    None 120
    Established 1200
    SYN Sent 120
    SYN Received 60
    FIN Wait 120
    Time Wait 120
    Close 10
    Close Wait 60
    Last ACK 30
    Listen 120

    The minimum value is 10

    You can set that for everything to quickly learn what happens when the values are reduced to the lowest setting. Generally speaking everything will still work OK but you see a drastic reduction in the numbers of connections. Setting 10 for some of these are much shorter than the values you will see recommended if you google for them, you can change them afterwards if you see anything failing. Google will help you there.

    I have up to 150 users online and rarely see more than 1000 connections, for example.

    The one that you need to keep long is TCP Established. Leave it alone. NB - In many routers this is set by default to several days. That is why the conntrack table always filled up and the router crashed.

    You will quickly get a feel for it.

    Some connections do need a bit longer timeout. For some VOIP the UDP timeouts must be long enough to permit the connection to begin, for example.

    Sorry for the slow/short responses. I am working away from home and have lousy web access.

    i tried tomato-WRT54G_WRT54GL-1.28.7633.3-Toastman-IPT-ND-Mini.bin for 1 week and the QOS just awesome.
    btw, what is the difference of Mini and Tiny?
    currently I have about 2,236KB Free Memory, whether TINY will do good on free memory?

    thanks Toastman

    It won't make any difference to the running of the router itself. You just have to choose a version that is small enough to be flashed. Stay with what you have.

    Do you mean, free NVRAM?

    In that case, they';ll all be the same. A linksys router with 60K would be useful.

    so, no different for TINY or MINI for my wrt54gl? in terms of free NVRAM, correct?
