Wireless Disconnecting and Reconnecting

Hi all,

There’s an issue in my mikrotik RB951G-2HnD. When I setup wireless connection it can be detected but when I connect with my notebook or smartphone it’s always connected and disconnected. This issue is not happened in one device but almost 5 devices with the same type.
Here are the screenshot of my log:

Can anyone give me help about that issue?

Thanks :slight_smile:
