[Q] Wifi problem after MM update

I come from Italy and I updated my device on March, as everyone, I think. My device is now perfect except the wifi. The wifi disconnect during the stanby and it connects only using the static mode. I also have this problem even if I changed the wifi option for the stanby in "always". Another strange thing is that the wifi is reported as one of the main cause of consumption, as it is shown in the screeshot
