    I was getting frustrated running my WRT54G router with standard Linksys firmware because of all
    the unexplained connection drops, and about 3 months ago I installed standard Tomato 1.19,
    and am now running Tomato 1.21 Speedmod.

    I have a Sony VAIO with Intel wireless and Marvell Yukon ethernet.

    Since upgrading to XP Service Pack 3 I have not bothered re-setting up my wireless and have my
    laptop hard wired to the router which is connected to a Speedstream 4100 Modem from ATT.

    Everything is working fine apart from when surfing the web with either Firefox 3.01 or Internet Explorer 7,
    a web site would fail to load, seemingly every hour.
    Using Firefox, I installed the Broadband Speed Test and Diagnostics Add-On which
    automatically checks whether the Internet conennction is working or not on a Page Load Error.
    Apart from the outdated links and human error, the Add-on would report back that the Internet connection is working.
    If I opened a new tab and entered a URL it would display but the one in the "bad tab" does not.

    When looking at the Tomato log files every hour there would be a single entry similar to this one since the
    defualt log configuration has a Mark Interval of 60 minutes.
    Aug 12 11:30:42 ATT Yahoo! -- MARK --

    I changed the Mark Interval on the router using to 15 minutes,
    and sure enough, when surfing the web every 15 minutes I got a page that failed to load, with the Add-on
    reporting that the connection was working and the router log had an entry for the same time.

    I changed the Mark Interval to 120 and am waiting for the 2 hours to pass to see what happens.

    Could the router temporarily "loose focus" for a brief nano-second when writing to the log file
    and that causes the open tab or window to "loose focus" also?

    I know that it's a strange set of circumstances, but it is the only explanation where the facts all come together.

    I am running now 1.19 so I can say that nothing like this happens using this version but it is very interesting because I had such problems on 1.21. I can't say with sure that the problem occured in moments when this MARK was shown il log because I don't remember but it could be like that. I have to say that in couple of hours with 1.19 there is no problem with stopping net for 10-20 seconds about which I wrote in other thread. So maybe this what you're writing about - MARK in log is connected with it.

    errm bad tab?
    does that mean that nothing would load in that particular tab but it loads fine in others? cuz that sounds like a client-side software issues to me (=

    anyways, i doubt syslogd can interfere with router operations in any way, so this is probably not the issue here

    Do you really need to use syslogd? I turn it off myself, as I find that it just consumes free RAM which is in short supply on 16MB routers.

    To me, the Mark Interval entries provide an incremental write to syslog and consume resources while the router could use more accurate timing. Under Administration > Logging > Syslog, I disabled MARK Interval, cron reporting while enabling NTP. Under Basic > Time set Auto Update Time set to every 2 hours.

    This gives me a "smarter" incremental log indication AND sets router timing within 1 sec.
