  • FTP causes modem reboot

    OK kids. This one has stumped Comcast, and it's been vexing me for ages.

    When I try to connect to an FTP site, about 60% of the time (near 100% for the first try at it) my modem/router will hang and reboot.

    Twiddling with settings in FTP doesn't seem to help much, but I'm willing to try any and everything again for the purposes of this exercise.

    Below is a sample of a connect log, trying to hook to my TG webspace. This is typical: the PASV command will run, and then the connection will hang on the LIST command.

    This phenomenon does not happen at any other time, with any other protocol, with any other type of connection. Version info on the equipment:
    Software version: SBG1000-0.1.3.3-SCM07-NOSH
    Hardware version: 1
    Upgrading the firmware is only an option if I can find it. The internet does not give up that secret to any query string I have thus far composed.

    Any tips would be greatly appreciated.

    I had this problems with a LinkSys router when I would do a traceroute. The router worked fine, but if I did a traceroute it would hang and reboot. I ended up bringing it back and exchanging it and then everything was fine.

    What is the make/model of the equipment?

        Ahh! It was a link!

        Damn me for not leaving my links underlined and damn whoever came up with this CSS scheme for the site as the link text doesn't quite stand out very well in the forums sometimes. :)

        That's a funny looking device! I'm actually stumped, short of just replacing it I don't have any ideas.

          Re: FTP causes modem reboot

          There's two issues with that.

          1) This thing isn't made anymore, and is well out of its return period.
          2) This problem hasn't been a constant thing since I purchased it. It started a while ago, yeah, but I recall having perfectly clean FTP connections with this piece of equipment.

          So that'd lead me to believe that SOMETHING SOMEWHERE happened to cause this. It also means that it's correctable, though it might not be able to be done as an end user.

            Re: FTP causes modem reboot

            I was going to inquire about having the latest firmware installed, but looking at the site there is no firmware for your device.

            The problem I think most likely lies in the gateway of the router, maybe with its NAT translation. I think it is that because those are the areas that the FTP has to go through those parts and if the firmware coding is screwed up it could cause a problem that freezes the machine and forces it to reboot. Since I am more of a hardware man and not a coder I won't comment on the firmware coding and the problems that it could be causing, but the hardware areas are most likely the bridge between the modem and the gateway of the router and the NAT used to direct the packets to your computers.

            I would suggest if you have the money and are truly mad at this is to get a new modem and wireless router, just remember to let Comcast know the MAC address of your new modem if you do get it.
