Hi, I have similar issue, as reported in this topic
Do you have also similar issues in the Supervisor and Host logs? I also find errors in other logs, like these are from Node-Red

I cannot fully understand if is strictly network related, or if something in my HA installation kept restarting automatically every few minutes.
I will try the radio off suggestion in the meantime.
