USG40 WLAN port Offline

Good morning, I have a USG40 unit and for two days I have had a problem with it, sporadically the WLAN interface goes offline, the only solution I have found is to reset it. Reviewing the log I find these reports but I don't know what I should do, can someone help me with the solution? Thank you. I copy part of the log

    I had similar issue with a USG60 few years ago.
    • Shutdown (via GUI) the device.
    • Wait for the communication of ended shutdown.
    • Unplug power adapter from the power socket/wall/whatever, keep it unplugged for 4 minutes at least.
    • Plug it back.

    Start monitoring again.
