Restarting the network using the terminal

So, you can shut down the network

sudo nmcli networking off

Then you can start it again.

sudo nmcli networking on

This restarts the network with nmcli.

Finally, you can use the commands ifdown and ifup which can be combined to disable and enable all network interfaces. As a result, the network in general will be restarted.

To use them, you can then run

sudo ifdown -a && sudo ifup -a

To restart the network, you will have to check the network icon and on the Wi-Fi or Ethernet interface turn the network off and on again.

In this way, and using the GNOME graphical interface, you will be able to reboot the network.
