I am using Kali Linux. My NetworkManager is enabled. But randomly my NetworkManager or networking.service goes down. Most of the time it's networking.service and my wifi is gone.
And Then I'm unable to turn on the networking.service
I think if I can configure the /etc/network/interfaces file properly then my issue might be fixed

ipnet, ifup, ifconfig
iwconfig
