Introduction To Restart Network

Restarting the network should be done carefully. You can do this task remotely by using SSH. That’s because your SSH is lost when you do networking. In some cases, you cannot start via SSH, you must connect directly to the Ubuntu machine.

Prerequisites To Restart Network on Ubuntu 22.04

How to Restart Network on Ubuntu 22.04

Restart the network in Ubuntu by using the command line. If you are using the Ubuntu server version, you are now in the terminal. But if you are using the desktop version, access the terminal using the keyboard shortcut Ctrl+Alt+T on Ubuntu. There are several commands available for rebooting the network in Ubuntu. Some of the commands that are mentioned below should also be applicable for rebooting the network in Debian and other Linux distributions.

Restarting Network Manager Service

The easiest way to restart the network is to use the command line. It is equivalent to the graphical way of doing it. Restart the Network-Manager service using:

sudo service network-manager restart

Now the network icon will disappear for a moment and then reappear.

Systemd Command for Managing Network

The service command is just a wrapper for this method, as well as for init.d scripts and Upstart commands. The systemctl command is much more versatile than the service. As you can see below:

sudo systemctl restart NetworkManager.service

Now the network icon will disappear again for a moment.

nmcli Tool for Managing Network

nmcli is another tool for managing networks on a Linux machine. A very powerful tool that is very useful. Many system admins choose it because it is easy to use. There are also two steps in this method: turning off the network and turning it on again:

sudo nmcli networking off

The network will turn off and the icon will disappear. To turn it back on, use the following command:

sudo nmcli networking on

ifup & ifdown Commands for Managing the Network

The ifup & ifdown commands directly handle the network interface and change its state to one that can send and receive data. Use ifdown to shut down all network interfaces and then use ifup to turn all network interfaces back on. The combination of both of these commands is very important. This step will not make the network icon disappear from your system and you will not be able to have any kind of network connection at the time:

sudo ifdown -a
sudo ifup -a

Now you have successfully restarted your network.

Restart the Network in Ubuntu Graphically

This step is the easiest network reset for Ubuntu desktop users. If it didn’t work, check the command-line options mentioned in the steps above.

NM-applet for Network Manager

NM-applet represents the system tray applet for NetworkManager. Use it to reboot the network. First, check the top panel. You should find the network icon in your system tray. Then click on the icon (volume or battery icon). This method opens the menu. Select the “Turn Off” option:
