Random disconnections

RouterOS General
1

I have an AP, configured as an ap-bridge
Multiple clients are connected as station-bridge.

The connected clients randomly disconnect for a few seconds.
The wireless connection is up but no IP packets are transmitted.
MAC ping also stops working.
After a few seconds, the connection is restored.

All Miktorik versions are 6.32.2.

Any idea what can cause this problem ? How can I troubleshoot that issue?

Thank you

After I enable debug in wireless I get this error:

if-wifi: no network that satisfies connect-list, by default choose strongest signal

I think for some reason mikrotik is searching for other SSID that is causing the disconnections problems…

Any idea why mikrotik produce this error?

Current mikrotik version installed is 6.33.3
