How to resolve the issue of network card not starting i…

In a Linux system, if the network card fails to start, you can try the following troubleshooting methods:

1. Check the network connection: make sure that the ethernet or wireless connection is working properly, and that the plugs are correctly connected to the ports.
2. Check the network card status: Use the command ifconfig or ip addr to view the status of the network card, ensuring that the network card is correctly recognized and assigned an IP address.
3. Restart the network service by using the command sudo systemctl restart network or sudo service network restart to ensure the network configuration takes effect.
4. Check network configuration files: Verify that the parameters of the network card such as IP address, subnet mask, and gateway are correctly set in the /etc/network/interfaces or /etc/sysconfig/network-scripts/ifcfg- configuration files.
5. Check drivers: Verify if the correct network card drivers are installed by using the command lspci -k to view relevant information about the network card and confirm if the drivers have been successfully loaded.
6. Check if the network service is running: Use the command “sudo systemctl status network” or “sudo service network status” to check if the network service is already running. If it is not running, you can try to start it manually.
7. Reboot system: If none of the above methods work, you can try rebooting the system, as sometimes a restart can resolve certain network issues.

If the issue persists, it is recommended to consult the relevant documentation for the Linux system or seek help from the community for a more detailed solution.
