rb1100 ahx2 packet drop and refuse to reboot.

Hello all!

RB1100 ahx2 suddenly started to drop packets on wan connections. The configuration didnt changed. In this case when i’m trying to reboot device using winbox or terminal command it hangs.- Nothing happens on console interface too. Only hard-reboot solves problem for a while. No high cpu load or ram overuse, no overheat, no viruses in script area.
I had updated ros and firmware to the latest Long-term, but glitch still alive. It appears randomly once a week or three times a day.

Any thoughts how to solve this? And what kind of glitch it is - hardware of software.

Thank you for your time!

Sorry, you do not provide any relevant detail.

The RB1100ahx2 would be getting a little old now. Check the power supply looking closely at capacitors with bulging tops. Swap the power supply if possible to confirm.
