The radio runs as wireless client. It's been stable for most of the time. But occasionally, I see error message like below. And usually after I see this message, client cannot ping AP (or at most intermittent). "iw wlan0 link" shows it's linked.

Can anyone help me understand what this problem is and is there a patch available?
