Enable Linux Network Card: Step-by-Step Guide

There are several ways to enable a network card in Linux system, with the most commonly used method being the ifconfig command.

1. Open the Terminal window.
2. Use the following command to view the network card information in the current system:

ifconfig

1. Look for the name of the network card you want to enable based on the information displayed by the ifconfig command, which typically begins with “eth” or “wlan”.
2. Use the following command to enable the specified network card (using eth0 as an example):

sudo ifconfig eth0 up

1. Please enter the administrator password to confirm the execution of the command.
2. Enter the ifconfig command again to confirm if the network card has been successfully enabled.

Additionally, you can use the ‘ip’ command to enable the network card, with the following syntax:

sudo ip link set eth0 up

Please note that in the above command, “eth0” is just an example, you need to replace it with the actual network interface name you want to operate on.
