WRT54GS problem

    I have the WRT54GS v6 and the problem I have is that the router spontaneously drops the internet connection. I know it's the router because i've tried the internet with a direct patch cable to the TA and i don't get the problem.

    When plugging the router back in, the line occasionally drops. It's not all the time but happens often enough to cause a few problems.

    I've updated the firmware to latest release to no avail. I've looked also at the tomato firmware but the release notes clearly state that it's not been tested on v6.

    As a work around, I normally just unplug the power to the Router, wait a few seconds then plug it back in (cold boot).

    Any ideas as to what's going on?

    Many thanks

    Well Admiral, a v6 is not a ship-shape router ;) It has limited flash and RAM, and runs a proprietary operating system, so we cannot check what it's doing. Search for the autopsy on this site to see the differences among WRT versions.

    A few questions:
    1) Does/can the router re-establish the internet connection if you just leave it when it drops?
    2) If you have 2 or more PCs connected to the router, can the 2 PCs still talk to one another?
    3) Are you running torrents, games, or other software that makes many connections to the internet?

    If your answer is No, No, Yes: Your router is most likely being saturated with the number of connections over it. Reduce the number of connections. (You'll have to figure that one out yourself as I don't know what software you are running.)

    Alternatively, and this is strongly recommended, load dd-wrt micro on the v6, and tune the TCP and UDP number of connections and timeouts to lower values. If you do load http://www.dd-wrt.com/ micro, be sure to follow the instructions to the letter - it's not that hard, but if you get hasty or skip certain steps you can brick the v6.

    If your answer to the questions is Yes, Yes, No: I would look at the WAN setup parameters. Your router may be dropping just the WAN connections because it don't understand something. In this case, loading dd-wrt micro is also recommended, as it may give you a bit more control over the WAN setup.

    Many thanks for your reply. I'm wondering now if I should have just purchased the WRT54L.

    The answer to those questions are

    NO - I have to unglug the router power.

    I'll certianly have a look at your recommendations and post back.

    What exactly am I looking for on that link?

    The WRT54GL would certainly have been the better bet, as you could pretty much load any firmware you please on that.

    Given your v6, you are looking for the dd-wrt micro firmware for the WRT54G or WRT54GS v6 on www.dd-wrt.com. You are also looking for instructions on how to load dd-wrt micro onto your v6, as it is not straight forward. You can start by dowloading the correct firmware from http://www.dd-wrt.com/dd-wrtv3/dd-wrt/downloads.html (I think it would be http://www.dd-wrt.com/dd-wrtv2/down...ksys, Asus etc.)/dd-wrt.v24_micro_generic.bin , but read a bit and make sure).
