How to Restart Network Interface in Linux

To restart a network interface in Linux, you can use the ifdown and ifup commands. Here's how:

1. Open a terminal window.

2. Type the following command to bring the network interface down:

sudo ifdown interface

Replace interface with the name of the network interface that you want to restart (e.g., eth0, wlan0, etc.).

3. Wait for the interface to be brought down.

4. Type the following command to bring the network interface up:

sudo ifup interface

Replace interface with the name of the network interface that you want to restart.

The network interface should now be restarted and active again.

Keep in mind that these commands may not work on all Linux systems. Some systems may use different commands or tools to manage network interfaces. In these cases, you may need to use a different method to restart the network interface.
