R500 short-term disconnection from the network

[Andriy]

Hello.
There are three R500 points in the network. Connected to Mikrotik POE. There is a short-term dump of one of the points (2-4 packages). If you turn it off, this problem appears on the second point. If you disable the second point, the problem appears on the third point.

2.4 and 5

Two, one for 2.4 and the other for 5. If you deplete them, the problem does NOT go away.

The problem was found.
One of the connected clients (device) had a problem. Just turned it off and the problem went away.
