Finally, I have a Mikrotik device to manage the sluggish internet in my home environment.
After reading Mikrotik reviews, various recommended videos, and Mikrotik setup tutorials, I decided on the Mikrotik RB952Ui-5ac2nD TC series.
Oh, for a comprehensive review of the Mikrotik RB952Ui-5ac2nD TC, it’s already published on Breedie.com. Here, we’ll focus on the self-problem only.
After setting it up and getting it ready for use, I left the black Mikrotik HAP AC Lite running 24/7.
Occasionally, I monitored the internet speed being delivered through a Huawei E3372 modem via the Winbox interface.

And then, I received the warning ‘Mikrotik System Error: Critical Router Rebooted Without Proper Shutdown’ through the Mikrotik Terminal window.
At first, I panicked. I was restless.
Could it be that I ordered the wrong Mikrotik device?
Could it be that the Mikrotik RB952Ui-5ac2nD TC is a defective product?
Could it be that my router has been infiltrated by malware to be used for Bitcoin mining by hackers from China?
Oh no… How did this problem escalate all the way to China?
This is not without reason, mind you.
I found this information through a Google search for self-help regarding Mikrotik system problems, errors, and critical issues. The Mikrotik log even appeared in red ink. 😱
Who wouldn’t be shocked?
Who wants to waste their money, especially when I spent nearly one million rupiahs on the Mikrotik RB952Ui-5ac2nD TC model?
Here’s how to resolve the ‘Mikrotik System Error: Critical Router Rebooted Without Proper Shutdown.’
You just need to perform a shutdown on the Mikrotik once whenever you receive this error message. After that, restart your Mikrotik routerboard. Voilà… The error message in the system log disappears instantly.
And the warning ‘System Error: Critical Router Rebooted Without Proper Shutdown’ in the Mikrotik Terminal window also vanishes immediately.
Here’s the cause of the Mikrotik RB952Ui-5ac2nD experiencing the ‘System Error: Critical Router Rebooted Without Proper Shutdown.’
This error occurs when there is a sudden power outage. It’s as if the Mikrotik RouterOS experiences a hiccup.
There are also shared experiences where the issue is not caused by a power outage but rather due to the router losing its internet connection, leading to hang-ups and restarts due to continuous client requests.
Another user’s experience could be a CPU load of 100%, and the system decides to auto-restart.
In my case, the issue was purely due to a power outage.
In conclusion: The best way to turn off the Mikrotik is to perform a shutdown, just like turning off a computer or laptop. This doesn’t mean you can simply unplug the charger, as Mikrotik has a heart. 💖
Solution: You only need to shutdown Mikrotik every time you get the error message.
