Hi guys first of all very nice community you have here!
Now to my problem 
We have just recently upgraded our router to Mikrotik rb450 package.
Everything is set up properly couse wan and lan works just fine.
The problem is after some time of working, router restart itself.(sometimes after 10 hours, sometimes after 24h)
Our router os is 2.9.46.
We have also unstable power in whole gaming center,so i have seen some errrors duo to power failure also on router.(router log)
Is mikrotik very sesnsitive to power variation?(maybe need ups for him?)
Now when it restarts log is empty and it doesn’t say why it did that 
I’am new to Mikrotik stuff so i need some pro help.
We are running 32 pcs on mikrotik with one wan connection(so no hard work for him i suppose)
Cpu goes from 32% to 80%…
Bad blocks are at 43…
But restarts are verry anoying
Please help and best regards from Kobatz
Hi,
Try to uninstall/Disable unwanted Packages from
/System Packages.
Reboot your Router and Check the Performance
Put it on a UPS and see if that fixes your problem. There was a restart problem with all RB4xx routerboards when power was lost for less than 1 second. A UPS will isolate that problem by eliminating short brownouts.
Also you cannot run RouterOS version 2.9.46 with an RB450. So you probably have an RB150 if you are really running that OS version.
In that case, ignore what I said because the RB150 did not have that restart problem.
