Ping Timeouts to the DietPi Device since switch from 157 to 6.16/6.17

Hi,

since I reinstalled my NanoPi Neo with 6.16 (and updated to 6.17) I got Ping timouts every 3-8 Pings…

And its definitly not the cable or the hardware, because I have no timeouts, when I switching menus in dietpi-config at fast speed. Looks like something goes to sleep -.- Got no problems with Version 157


plz help
