MikroTik Gateway Update
This guide walks you through updating RouterOS packages and the RouterBOARD (firmware/“BIOS”) using the Winbox 4.
Prerequisites
- Admin access (username & password)
1. Update RouterOS Software
In the left panel System → Packages → Check for Updates. A new window will open, check if the versions match. If not, click Download&Install and wait a few minutes.

2. Update RouterBOARD (Firmware/“BIOS”)
- In the left menu, open System → RouterBOARD.
- Compare Current Firmware with Upgrade Firmware.
- If an upgrade is available, click Upgrade.

3. Reboot to Apply Firmware
- In the left menu, open System → Reboot.
- Confirm the reboot to apply the RouterBOARD firmware upgrade.

- Wait for the device to come back online, then log in again.
4. Verify the Update
- System → Packages:
- Click Check For Updates — it should now report up to date (both versions should match).
- System → RouterBOARD:
- Confirm that Current Firmware now matches Upgrade Firmware — meaning the firmware is successfully updated.
