No internet on new CentOS, what's wrong?

Question

linux

I'm running CentOS 7 only installed not on the Internet.
I look at the logs

journalctl -xe

Displays 2 errors: 1) Dependency failed for Network Manager Wait Online.
NetworkManager-wait-online.service unit error
2) Next, it activates the router interface, but there is no connection with it, probably due to the first error and an error is generated:
Failed to start LSB: Bring up/down networking.
What could it be, google did not find anything sensible!

Answer 1

And if you say:

systemctl enable systemd-networkd.service
systemctl start systemd-networkd.service
