## Troubleshooting

<Accordion title="My microSVC disconnects after a random period of time">
  <Note>This fix only applies to orders placed prior to June 2026.</Note>

  **What's wrong?** Your microSVC works for a while, then suddenly drops the connection. This one-time fix is know to solve it. It takes about 5 minutes.

  Just follow each step in order. Copy each command exactly as shown.

  <Steps>
    <Step title="Open the terminal">
      Connect to the microSVC over SSH. When asked, enter:

      * **Username:** `dwe`
      * **Password:** `deepwater`

      Not sure how? Follow [this guide](https://docs.dwe.ai/dwe-os/pages/terminal#accessing-the-terminal) first, then come back here.
    </Step>

    <Step title="Copy and paste this command, then press Enter">
      This applies the fix. Nothing will look like it happened — that's normal.

      ```bash theme={null}
      cmdline_path=""
      for candidate in /boot/firmware/cmdline.txt /boot/cmdline.txt; do
          if [ -f "$candidate" ]; then
              cmdline_path="$candidate"
              break
          fi
      done

      if [ -z "$cmdline_path" ]; then
          echo "Warning: cmdline.txt not found in /boot/firmware or /boot, skipping USB quirks configuration."
      else
          # Idempotent: only append if the quirk isn't already there
          if ! grep -q 'usbcore.quirks=0bda:8152:k' "$cmdline_path"; then
              sudo sed -i -e 's/$/ usbcore.autosuspend=-1 usbcore.quirks=0bda:8152:k/' "$cmdline_path"
              echo "USB quirks added to $cmdline_path"
          else
              echo "USB quirks already present in $cmdline_path, skipping."
          fi
      fi
      ```

      <Tooltip tip="It adds two settings to the device's startup file that stop the USB Ethernet adapter from powering itself down. That power-saving behavior is what causes the random disconnects.">What does this command do?</Tooltip>

      <Warning>If you see `Warning: ... not found`, stop here and contact support — the fix was not applied.</Warning>
    </Step>

    <Step title="Restart the microSVC">
      Type this command and press Enter. The device will reboot, which takes a minute or two.

      ```bash theme={null}
      sudo reboot
      ```
    </Step>

    <Step title="Check that it worked">
      Once the device has restarted, open the terminal again (Step 1) and paste this command:

      ```bash theme={null}
      for d in /sys/bus/usb/devices/*/; do
        vid=$(cat "$d/idVendor" 2>/dev/null)
        pid=$(cat "$d/idProduct" 2>/dev/null)
        [ "$vid:$pid" = "0bda:8152" ] && echo "$d" && cat "$d/quirks"
      done
      ```

      <Tooltip tip="This only reads information — it makes no changes. It finds the USB Ethernet adapter and prints back its current setting so you can confirm the fix is active.">What does this command do?</Tooltip>

      <Check>If you see `0x400` in the output, the fix worked. You're done! If you don't see it, repeat the steps or contact support.</Check>
    </Step>
  </Steps>
