Problem in interface

[chpmotry]

Hello everyone, good time.

I have a wireless link. At different times, the connection between the radio and the switch is constantly up and down, and the bandwidth fluctuates between 100 megabits and 1 gigabit.

I also tested the network cable on the switch. The network cable is OK in terms of the connection of the wires according to the standard. There are several possibilities here: either the network cable is faulty. Either the radio's ether port is faulty or the switch port is faulty. I moved the switch port, but the problem still exists.

Do you think there is a solution?

I attached switch loggs on my post now

  - @chpmotry   Ok, can you also check  logs on the mikrotek station bridge ?

Unfortunately, I turned the radio off and on and its logs stored in RAM were erased. But I saw them before they were deleted. In a day, for about two to three hours, at intervals of a few minutes, its Ethernet link connected to the switch would go up and down regularly. And sometimes the bandwidth would drop from one gigabit to a hundred megabits.

 - @chpmotry  In my opinion the problem is related to the external infrastructure : bridge and access point , not the switch. Try to get logs from those anyway and or tweak network settings on the bridge , if possible,

See if that stabilizes the connection.  Keep this link under observation for, at a minimum, a week.
