Hi @Max_Si 

It looks like the EAP didn't get a proper power supply.

How did you power on the EAP?

When the issue happened, did you observe the LED status of the EAP?

Hello, 

EAP is powered by the power supply that came in the box of EAP.

Havent observed as EAP is hidden, will try to observe.

Interesting fact, yesterday after I posted this, I got all users off from wifi 5ghz of EAP. And I havent see any link up/down after that..

Hi  @Max_Si 

Do you mean this only happening on 5G, and meanwhile, the 2.4G is working correctly?

Is the firmware the latest?

  @Vincent-TP 
I dont really use 2.4 g.  I dont have devices connect to it. I moved devices to another wifi AP  ( Archer c7)
So for now I`m using only 5g for my computers, phone, etc..

Latest Available firmware for EAP.

What I did, is that I moved yesterday all clients from 5g wifi to same archer c7.
So today I checked logs on my mikrotik, and didnt saw any links down/up events.

I will monitor today, and will add 1 devices one by one in some interval of time.
