    But I will still have to upgrade to fix the security issues. Are these
    firmwares always secured (no security holes)?

    LOL! My computer friends teased me that I am unlucky with electronics.
    But then that is why I am a software quality assurance (SQA) tester. I
    break stuff easily. :/

    If the router is bricked, how can one tftp/telnet? I have no idea what
    jtag is (new to me). I assume it is this:
    http://en.wikipedia.org/wiki/Joint_Test_Action_Group (hardware stuff).
    If so, then I am not a hardware person (can't even use a screw driver
    due to my multiple physical disabilites). :(

    So it doesn't matter which WRT54 I get, it is good and usable by third
    party firmwares, right? If that is the case, then I know what my future
    one is going to be. :)

    Oh, ok, so the physical button on the front of the router would be a
    good thing.

    No security holes? EVER? Come on, now. :)
    There are new exploits being dreamt up every day. Every now and then
    one is targeted toward these kinds of devices, but generally they go
    after the millions of Windows PC's out there, right? It shouldn't be
    something that causes great concern, but that's your call.

    Even when bricked, they usually have about a 5-second window of
    opportunity as they are being powered up. If that fails, there's a
    special procedure where you connect a jtag cable to the circuit board,
    connect the other end to the PC, and do some magic. Yes, it means
    acquiring the jtag cable and opening up the router case, but it's
    pretty rare to get to that point. Don't do firmware upgrades via
    wireless and you'll be pretty much ok.

    If you're asking me, it doesn't matter as long as it's a WRT54GL. I
    don't think it's worth saving a few bucks and getting a WRT54G. The L
    makes a difference.

    Yeah, I always read don't do it via wireless. I remember upgrading a

    Re: Linksys BEFSX41 v1 router locking up?

    Had another one earlier. I seem to notice a pattern. I think it only
    happens when I am heavily using the Web on my updated Windows XP Pro.
    SP3 (IE6) machine, in loading many tabs in Mozilla's SeaMonkey v1.1.18.
    And this is usually after I haven't used the Internet a lot from heavy
    usage for a while. I don't seem to see this when I use my older box with
    Debian/Linux with the same Web browser. I also don't see this when
    downloading heavily (peak speeds) with downloaders.

    I am planning to do my router's settings reset next weekend when I have
    more free time and when less people are using the network in case
    something goes wrong or whatever, and I don't get complaints. ;)

    Skim back through this thread and I think you'll see that we keep
    saying WRT54GL and you keep saying WRT54G. :)

    Those are two different models, and I'm saying that the WRT54GL is
    "better" for this purpose than the vanilla WRT54G.

    IIRC, there are a few dd-wrt feature upgrades every year, but I can't
    say I remember the last time there has been a security upgrade. There
    probably has been one at some time, but I don't remember it. I would
    say you generally aren't forced to upgrade unless you want to.

    It has been over 20 days of no new lockups. Either I am having good luck
    (not declaring fixed/resolved yet) or I fixed it(?). Funny thing is that
    I did not reset my settings or downgrade! The only thing I changed was
    to enable MTU size to 1500.

    Per chance, do you remember what it was before you changed it?

    It was disabled and no value? (greyed out). Router's internal help said
    "Select Disable toturn off MTU. Select Enable to manually set the MTU
    size.Enter an appropriate size; check with your ISP for more
    information. Manually setting the MTU is not required by all ISPs."

    If this indeed fixed the lockup issue, then that makes no sense? Maybe I
    am just being lucky. :P

    I vaguely remember manually configuring a 1500 byte MTU on a very old
    Linksys router way back in about 2002 or so. Seems like it was one of
    the original BEFSR41's that were common in the day, but I could be
    wrong about that. I think the default was 1480 or 1492, something like
    that. My theory is that packets larger than that would naturally have
    to be fragmented, which would be fine, until a large packet came along
    with the Do Not Fragment bit set, and the firmware would freak out. In
    my case, the issue was initially resolved by manually specifying the
    1500 byte MTU, but later firmware versions fixed the entire behavior.

    Maybe your case is somewhat similar, given the age of the BEFSX41.

    You might want to check out the freeware program SG TCPOptimizer found at
    http://www.speedguide.net/downloads.php

    It can look at your link and give you actual feedback as to what your
    particular
    MTU values need to be set at in order to have the best link. I believe the
    Mirror sites
    listed there have the newest version available for downloading.

    Yeah, mine is the original model. But I don't ever recall enabling and
    setting MTU size with previous firmwares. [shrugs] I know I can use the
    Internet like crazy. :) Let's hope this enabled MTU's 1500 was it to fix
    the rare random lock ups.

    If not, then reset firmware settings or downgrade! :P

    I love routers ;-)
    My MTU setting is disabled and has 1500 as greyed value.
    I couldn't find a Wallwatcher backup but what I remember during my tests
    is that the router dumped a Wallwatcher entry with MTU = 1500.
    And if I look at the router Status page it said MTU = 1500.

    In the manual you get the advice to set MTU = 1492 , but for some reason
    I set it to 1500. My other linksys router also works with MTU = 1500.
    I think Char Jackson has a good point with his idea of freaking out
    firmware.
    Maybe that's why I got back to 1500.
    No lock-up problems with my router so I think you shouldn't downgrade for
    a lower MTU value. You decide what your working MTU value is.
