Moto-E XT-1022 // WiFi disconnect on Suspend...

Hi guys, my XT-1022 is losing wifi connection when the phone is in suspend mode, even if the setting "Keep Wi-Fi on during sleep" is set to "Always"...
This is happening with any ROM... AICP - Exodus - CM12.1 - AOSP - SlimLP - Orion - Blisspop...

Any TIP?

Many thanks!!!
