The problem is NetworkManager working in Kali Linux?

Hello, eth0 falls off after a few hours of work in Kali Linux. Restart Network Manager does not help. I checked the command (ip a) that the computer sees the ethernet. Most likely something in Network Manager. What could be the problem?

In NetworkManager.conf tried to change c false to true does not help.

To kill NetworkManager and configure manually.
