Raspberry Pi 3 loosing wifi - busy status

[mgouin]

Thanks for the commands, I will try that next failure...

I don't know if it's related, but I also noticed that recently, my ssh connections are becoming unreliable.

I explain: Usually, I can connect with no problem. On some rare occasion, just after password entry, there is a long delay of about 30 seconds.

But the most frequent issue is that regularly, while typing, the ssh session seems to not accept any keys. The session is still open, I can ping the PI so network is not down. However the session does not respond to any keypress. After about 30s to 1min (approx), this usually comes to normal and the "buffered" keys appear in the bash prompt. Then, I can type without lag for 1min, then freeze again.

This is driving me nuts...
