How to Restart Network Services in Ubuntu 24.04
You restart network services in Ubuntu 24.04 to apply configuration changes or fix connectivity issues.
Network services manage how your Ubuntu system connects and communicates with other devices. This includes everything from your Wi-Fi adapter to internet protocols.
Applying changes to network configuration files, such as those managed by Netplan, requires restarting these services to become active. For instance, after editing a Netplan YAML file, a restart is crucial.
This action is also a common troubleshooting step when you encounter network problems, effectively resetting your network adapter and re-establishing communication.
Restart Ubuntu 24.04 network services using `sudo systemctl restart NetworkManager` in the terminal. Alternatively, use `nmcli networking off && nmcli networking on` or the `nmtui` interface. These commands reset network connections to apply changes or fix issues.
Restart network services using Systemd
In most Ubuntu systems, the most common way to restart network services is to use the Systemd command.
To do that, run the command below.
sudo systemctl restart NetworkManager
sudo systemctl restart NetworkManager.service
Restart network services using the NetworkManager CLI
Another way to restart the network services in Ubuntu is to use the NetworkManager CLI command (nncli).
To do that, first, list the network interfaces by running the command below.
nmcli connection show
Then, use the command format below to turn down or up the network interface.
sudo nmcli connection down <interface_name>
Replace <interface_name> with the corresponding interface you want to turn down or up.
You can turn the network on/off entirely using the command below, thus restarting the network services.
sudo nmcli networking off
sudo nmcli networking on
Restart network services using the NetworkManager Text User Interface (nmtui)
Another way you can restart network services in Ubuntu is to use the NetworkManager Text User Interface (nmtui).
The nmtui command provides a simple and interactive way to manage network configurations.
Run the command below, select deactivate, and reactivate the network services.
nmtui
Use the screen to deactivate and reactivate the interface.
Restart network services using ifup / ifdown

Run the command below to list all the interfaces.
ip a
Then, use the command format below to turn on/off the network interface.
sudo ifdown <interface_name>
sudo ifup <interface_name>
Replace the <interface_name> with the corresponding interface in your system.
For example, run the command below to shut down the enp0s3 interface.
sudo ifdown enp0s3
To bring up the same interface, run the command below.
sudo ifup enp0s3
That should do it!
