How to Restart Network Services in Ubuntu 24.04
Restarting network services in Ubuntu 24.04 clears up network problems and applies new settings.
Network services are the hidden programs that keep your computer connected to the internet and other devices. They control things like your Wi-Fi or Ethernet connection.
You often need to restart them after changing network setup files. For example, after you edit a Netplan configuration file, a restart makes sure the changes work correctly.
This simple step also fixes many common connection issues by giving your network a fresh start.
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
Restarting network services with Systemd: For most Ubuntu systems, the go-to method is the Systemd command. Here’s how you run it:
Run the command below.
sudo systemctl restart NetworkManager
sudo systemctl restart NetworkManager.service
Restart network services using the NetworkManager CLI
Restarting network services with the NetworkManager CLI: If your internet isn’t working right, you can use the nmcli command. This tool lets you disable and then re-enable your network connections by their specific names. It’s a quick way to fix connection problems without a lot of typing.
To start, list the network interfaces by running the command below.
nmcli connection show
Then, use the command format below to disable or enable the network interface.
sudo nmcli connection down <interface_name>
Replace <interface_name> with the name of the network interface you want to disable or enable.
You can turn the network on or 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)
Restarting network services with the NetworkManager Text User Interface (nmtui): Ubuntu offers an approachable text-based menu with the nmtui tool. It lets you manage network settings without complicated commands. Simply run nmtui, select to turn your network off, and then turn it back on to restart the services.
The nmtui command provides an interactive way to manage network configurations.
Run the command below, select deactivate, and then reactivate the network services.
nmtui
Use the screen to deactivate and reactivate the interface.
Restart network services using ifup / ifdown
Restarting network services with ifup / ifdown: For older methods, you can use the ifup and ifdown commands in Ubuntu. First, find the name of your network connection. Then, use ‘ifdown’ to turn it off and ‘ifup’ to turn it back on, which restarts the service.
Run the command below to list all the interfaces.
ip a
Then, use the command format below to turn the network interface off or on.
sudo ifdown <interface_name>
sudo ifup <interface_name>
Replace the <interface_name> with the name of the network interface on 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 complete the process!
