In my device, I have sometime trouble to establish connection with the router. I have a loop running with reconnect callback and the -11 error :

Could you help me concerning the meaning and cause of error -11 ? It can disappear for a period of time and come back. No source code revision relevant, I always saw it but feel it is maybe more frequent (or I am less tolerant).
I try different router, different hardware.
Could it be due to noisy environment ?
Thanks to everybody
