Unable to access SG-1100 via serial or web gui

  • I received my Netgate SG-1100 last night and was able to successfully set it up using the local IP address This morning I believe I made a mistake as my intention was to change the local ip address to but upon saving the changes I am no longer able to access the device through the webgui I have also attempted to connect to the devices through the serial cable/putty and am unable to. The black diamond symbol on the device itself flashes rapidly about every 30 seconds or so....At this point I would like to factory reset it and start from scratch but I am unable to get access to it.

    did you remove the power cable accidentaly without powering it off?

    did you follow this instruction to connect to the console?


    if you manage to connect via console try a factory reset from the menu or see if it show any error and report back

    or you can ask for support at https://go.netgate.com , register and open a ticket

  • So I've been able to establish a connection to it via the serial connection.......it is in fact in a boot loop I am going to attach a screenshot here, I have in fact opened a ticket with Netgate support as well. SG1100SerialSS.png

  • I have been attempting to follow the instructions to reimage the device here
    but am getting the below error when attempting to run "run usbrecovery".

    Try with another USB thumb.
    Follow the instructions 1:1 here: https://docs.netgate.com/reference/create-flash-media.html

    The actual panic error you're seeing there shows it's a filesystem error. You can probably recover form that using fsck from single user mode if you have not flashed it yet:

    1. At the SG-1100 console press any key to interrupt the boot loader when you see:
      Hit [Enter] to boot immediately, or any other key for command prompt.

    At the 'loader>' prompt enter: boot -s

    That will boot in single user mode to a question asking for a path to the shell, just press return to reach the # prompt.

    1. At the # prompt run the following command: fsck -y /

    Run the fsck command at least 3 times; Repeat the command until no errors are reported, even if fsck claims the filesystem has been marked "clean".

    1. Reboot by running: reboot
