Rpi3 B+ Volumio 2.657 network problem

Hi all,
I’ve installed volumio v.2.657 on my Raspberry Pi 3 B+. Network randomly does not work. I’m unable to reach volumio and i’m unable to ping the ip address. If i reboot the Rberry, it answers to ping and after random time, again it does not answer. I’ve tried to plug monitor and keyboard and i’ve noticed that i’m unable to write. Terminal does not answer.
If i try to install the previous version, keyboard is ok and i’m able to access the cli but the network problem is still present.
I’ve tried to disable BT and WiFi via CLI but the problem is still present.
I’ve tried to disable the cable network,enable WiFi and disable BT, the problem is still present.
All works well with a Raspberry Pi 2.

Can you help me to solve the problem?
Thank you.
