Check uptime and RouterOS version

The system uptime is displayed in the system resources output.

/system/resource/print

Example Output:

                   uptime: 1w2d10h2m52s        <-- Uptime
                  version: 7.17 (stable)       <-- RouterOS version
               build-time: 2025-01-10 11:30:08
              free-memory: 21.1MiB
             total-memory: 64.0MiB

                cpu-count: 1
            cpu-frequency: 400MHz
                 cpu-load: 16%

          total-hdd-space: 64.0MiB

         write-sect-total: 486250
               bad-blocks: 0%

               board-name: RB750GL
                 platform: MikroTik

Check RouterOS Firmware version

We can check the firmware version by running the following command.

/system/routerboard/print

Example output:

       routerboard: yes
             model: RB750GL
     serial-number: XXXXXXXXXXXX
     firmware-type: ar7240
  factory-firmware: 3.29
  current-firmware: 7.17
  upgrade-firmware: 7.17

If there is a line that says ;;; Firmware upgraded successfully, please reboot for changes to take effect!, then the firmware has been updated at some point and the router needs a reboot to apply it. Remember you need to update both the RouterOS version and the firmware version when upgrading.
