Why “System” is using the network? Here is an attachment.

I’m not the person to ask really but I did recall seeing 3 system connections after initially connecting to the net then they vanished but as to whether your query is the same as mine I wouldn’t know

I’ve seen other users with the same, but could never figure out except on my own PC: I allowed all ICMP traffic in Network Monitor and when it utilizies, the system process briefly appears. This is normal. Your picture, however, is due to something else that I don’t know.
