OK, so after upgrading to ROS 7.1 from 6.49.1, I found out that most of my CAP-ACs randomly get disconnected.
So I decided to downgrade to the latest 6.x version, which, at the time of this post is 6.49.2.
So, here’s how to do it:
Find the architecture of the Mikrotik device
- open Winbox and go to System -> Ressources. Look for the Architecture name field. (see examples below)
or
Download the RouterOS image from your Mikrotik device
- you can download the desired ROS version for your Mikrotik device (be careful on the architecture) from here: https://mikrotik.com/download
The files look like:
routeros-mipsbe-6.49.2.npk for MIPSBE
routeros-arm-6.49.2.npk for ARM
Upload the RouterOS firmware to the Mikrtotik Device’s Root Directory
- From Winbox, click on Files menu item. File List window will appear.
- Drag and drop the downloaded NPK file to this File List window. Then, the file will be uploaded to MikroTik root directory
Issue the Downgrade command
- From Winbox, go to System -> Packages menu item. Package List window will appear
- Click on Downgrade button from this window
- It will ask to Confirm Reboot. Click on Yes button.
The system will be rebooted and after reboot you will find that your RouterOS has been downgraded.
Downgrading Mikrotik firmware
If you upgraded firmware before, you also need to downgrade firmware. The following steps will show how to downgrade MikroTik Firmware properly.
From Winbox, go to System -> Routerboard menu item. Routerboard window will appear.
Check your Current Firmware and Upgrade Firmware version.
If the Current Firmware version is greater than the Upgrade Firmware version, click on Upgrade button. It will ask to confirm upgrade. Click Yes button to upgrade firmware.
Now reboot MikroTik Router. After reboot you will find that Firmware has been downgraded.
Enjoy!
